Test Case Design in Manual Testing Interview Questions.
### Test Case Design in Manual Testing
9. What is Equivalence Partitioning?
Ans: Equivalence Partitioning is a software testing technique used to systematically reduce the number of test cases needed to test a software system while maintaining reasonable test coverage. It is based on the principle that inputs and outputs of a system can be divided into groups or sets that exhibit similar behavior. The idea is to choose a representative test case from each partition, assuming that all inputs and outputs within a partition behave in the same way.
Key concepts of Equivalence Partitioning:
1. Equivalence Class:
– An Equivalence Class is a set of input values that are expected to be processed or responded to in the same way by the software. Testers identify these classes to streamline test case selection.
2. Partitioning:
– The process involves dividing the input domain into different partitions or groups based on common characteristics. Each partition represents an equivalence class.
3. One Test Case per Equivalence Class:
– The goal is to design one test case that represents each equivalence class. Testing a single representative value from each class is expected to provide sufficient coverage for all values within that class.
4. Reduced Test Cases:
– Equivalence Partitioning helps reduce the number of test cases needed to test a system, especially in cases where the input space is extensive. By selecting a single test case from each equivalence class, testers aim to cover the entire input domain.
5. Assumption of Similar Behavior:
– The technique assumes that if one input value within an equivalence class behaves in a certain way, all other values in the same class will exhibit similar behavior. Therefore, it is sufficient to test only one representative value.
Example:
Consider a system that accepts positive integers and calculates their square roots. The input space can be divided into the following equivalence classes:
– Equivalence Class 1: Positive integers less than 10
– Equivalence Class 2: Positive integers between 10 and 100
– Equivalence Class 3: Positive integers greater than 100
For Equivalence Class 1, one representative value (e.g., 5) can be chosen for testing. The assumption is that if the system correctly calculates the square root of 5, it will behave similarly for other positive integers less than 10.
Similarly, one representative value each from Equivalence Class 2 and Equivalence Class 3 can be chosen for testing.
Advantages of Equivalence Partitioning:
1. Efficiency:
– Reduces the number of test cases needed, making the testing process more efficient.
2. Coverage:
– Provides reasonable coverage of the input space by testing representative values from each equivalence class.
3. Simplicity:
– Simplifies test case design and management, making it easier to focus on critical scenarios.
Equivalence Partitioning is particularly useful for systems with a large and complex input space, helping testers design effective test cases while optimizing testing efforts.
10. Explain Boundary Value Analysis.
Ans: Boundary Value Analysis (BVA) is a software testing technique that focuses on testing the boundary values of input domains. The idea behind this technique is that errors often occur at the extremes or boundaries of input ranges rather than in the middle. By testing values at the edges of the input domain, testers aim to uncover potential issues related to boundaries, such as off-by-one errors, boundary crossing errors, and other boundary-related defects.
Key principles of Boundary Value Analysis:
1. Input Domain Partitioning:
– The input domain is divided into partitions, and test cases are designed to cover the boundaries of these partitions. Partitions include valid, invalid, and extreme values.
2. Boundary Values:
– Test cases are focused on the boundary values or points where the input transitions from one partition to another. These values are typically the minimum, maximum, and values immediately before and after these limits.
3. Boundary Conditions:
– Testers pay special attention to conditions at the boundaries, such as equality, less than, greater than, and other boundary-related conditions.
4. Testing Values:
– For an input variable with a specified range (e.g., 1 to 100), the boundary values would be 0, 1, 100, and 101. These values are tested to verify that the system behaves correctly at these critical points.
5. Edge Cases:
– Edge cases are scenarios where an input value is at the edge of its valid range. Testing these edge cases helps identify issues that may arise due to boundary conditions.
Example:
Consider a system that accepts user ages between 18 and 65 for a specific service. Using Boundary Value Analysis, the test cases would focus on the boundaries:
– Minimum valid age: 18
– Maximum valid age: 65
– Values just below the minimum: 17
– Values just above the maximum: 66
Test cases would be designed to check how the system handles these boundary values, ensuring that it behaves correctly and does not allow invalid input or reject valid input.
Advantages of Boundary Value Analysis:
1. Error Detection:
– Effectively detects errors and issues related to boundary values, which are common sources of defects.
2. Efficiency:
– Provides a focused and efficient approach to testing, as it concentrates on critical values that are more likely to reveal defects.
3. Coverage:
– Offers a way to achieve reasonable coverage of the input domain by testing values at the edges of partitions.
4. Simplicity:
– Test case design is simplified by concentrating on a limited set of critical values.
Boundary Value Analysis is particularly useful in situations where input values have specific valid ranges, and the system behaviour at the boundaries is critical to its correctness and reliability. It complements other testing techniques and contributes to a more comprehensive testing strategy.
11. What is Test Scenario?
Ans: A Test Scenario is a high-level description of a test, capturing the overall functionality or a specific feature to be tested. It provides a context for the detailed test cases that will be developed to verify the desired behavior of the software application. Test scenarios are derived from the requirements and serve as a basis for designing test cases and executing tests.
Key characteristics of a Test Scenario:
1. High-Level Description:
– A Test Scenario provides a broad, yet concise, description of what needs to be tested. It is not detailed but gives an overview of the feature or functionality under consideration.
2. Objective:
– The primary objective of a Test Scenario is to define what aspect of the application will be tested. It outlines the specific conditions or situations that the testing team needs to validate.
3. User-Centric:
– Test Scenarios are often written from a user’s perspective, focusing on how a user interacts with the system to achieve a particular goal or execute a specific task.
4. Independent of Implementation Details:
– Test Scenarios are independent of the implementation details of the software. They focus on the expected behavior and outcomes rather than the specific steps or code behind the functionality.
5. Helps in Test Case Design:
– Test Scenarios serve as a foundation for the creation of detailed test cases. Each scenario can be broken down into multiple test cases, each addressing a specific aspect or condition.
6. Traceability:
– Test Scenarios provide traceability back to the requirements. They ensure that the testing efforts are aligned with the specified features or functionalities outlined in the project documentation.
Example of a Test Scenario:
Consider a banking application with the requirement to transfer funds between two accounts. The corresponding Test Scenario might look like this:
– Test Scenario: Transfer Funds
– Objective: To verify that funds can be successfully transferred from one account to another within the banking application.
– Conditions:
– The user is logged into their account.
– Sufficient funds are available in the source account.
– Steps:
1. Navigate to the “Transfer Funds” section.
2. Enter the destination account details.
3. Enter the amount to be transferred.
4. Click the “Transfer” button.
– Expected Result: The funds should be successfully transferred, and the user’s account balances should be updated accordingly.
This Test Scenario provides a high-level overview of what the testing team needs to verify in terms of transferring funds. Test cases derived from this scenario would provide detailed steps, input data, and expected outcomes.
In summary, Test Scenarios act as a bridge between high-level requirements and detailed test cases. They help define the scope of testing and ensure that testing efforts are aligned with the intended functionality of the software application.
12. Define Test Case and Test Script.
Ans: Test Case:
A Test Case is a detailed set of instructions, conditions, and variables that are used to perform a specific test or validation of a particular aspect of a software application. It outlines the steps to be executed, the input data to be used, the expected results, and any other conditions necessary to verify that the software behaves as intended. Test cases are derived from test scenarios and are designed to ensure thorough testing of individual functionalities or features.

4. Click the “Login” button.
– Expected Result: The user should be successfully logged in, and the application’s home page should be displayed.
Test Script:
A Test Script, often associated with automated testing, is a set of instructions written in a scripting language that specifies the actions to be taken, the conditions to be checked, and the expected results for the automated testing of a particular functionality or scenario. Test scripts are used to automate the execution of test cases, allowing for more efficient and repeatable testing, especially in scenarios with large test suites or frequent test execution.
Key characteristics of a Test Script:
1. Scripting Language:
– Written in a scripting or programming language suitable for automated testing tools (e.g., Python, Java, JavaScript).
2. Actions and Verifications:
– Specifies the actions the automated tool should perform (e.g., clicks, data inputs) and the verifications it should make (e.g., checking expected outcomes).
3. Parameterization:
– Often allows for parameterization, where variables or data values can be dynamically replaced during execution to simulate different scenarios.
4. Integration with Test Framework:
– Integrated into a test automation framework, providing additional capabilities such as test setup, teardown, and reporting.
5. Reuse and Modularity:
– Structured for reuse and modularity, allowing components of the script to be used across multiple test cases or scenarios.
Example of a Test Script (Selenium WebDriver with Java):
“`java
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
public class LoginTestScript {
public static void main(String[] args) {
// Set the path to the ChromeDriver executable
System.setProperty(“webdriver.chrome.driver”, “path/to/chromedriver.exe”);
// Create a new instance of the ChromeDriver
WebDriver driver = new ChromeDriver();
// Open the application login page
driver.get(“https://example.com/login”);
// Enter a valid username
WebElement usernameInput = driver.findElement(By.id(“username”));
usernameInput.sendKeys(“testuser”);
// Enter a valid password
WebElement passwordInput = driver.findElement(By.id(“password”));
passwordInput.sendKeys(“password123”);
// Click the “Login” button
WebElement loginButton = driver.findElement(By.id(“loginButton”));
loginButton.click();
// Verify that the user is successfully logged in
WebElement homePage = driver.findElement(By.id(“homePage”));
if (homePage.isDisplayed()) {
System.out.println(“Login test passed”);
} else {
System.out.println(“Login test failed”);
}
// Close the browser
driver.quit();
}
}
“`
In summary, a Test Case is a detailed set of instructions for manual testing, specifying the steps, conditions, and expected results. A Test Script, on the other hand, is a set of automated instructions written in a scripting language for automated testing tools. Both are essential components of a comprehensive testing strategy, whether manual or automated.
13. What is Positive Testing?
Ans: Positive Testing, also known as “Happy Path Testing,” is a testing approach that focuses on validating that a system behaves as expected under normal or favourable conditions. In Positive Testing, the test cases are designed to verify that the software functions correctly when provided with valid input data and follows the expected paths of execution. The goal is to ensure that the application behaves as intended under typical scenarios without encountering errors or unexpected behaviours.
Key characteristics of Positive Testing:
1. Valid Input Data:
– Positive Testing involves using valid and expected input data to test the application’s functionalities. This includes providing inputs within the specified ranges, formats, or conditions defined in the requirements.
2. Expected Outputs:

Effectively managing defects contributes to the overall stability, performance, and success of the software product.
Define the life cycle of a defect.
Ans: The life cycle of a defect, also known as the defect life cycle or bug life cycle, refers to the stages that a defect goes through from its identification to its resolution and verification. The defect life cycle is a structured process that helps manage and track defects effectively. The stages may vary slightly depending on the development and testing methodologies used by an organization. Here’s a common representation of the defect life cycle:
1. New:
– The defect enters the life cycle when it is first identified and reported. This stage is often initiated by testers during the testing phase or by users who encounter issues in a production environment.
2. Assigned:
– After a defect is reported, it is assigned to the development team or a specific developer for analysis and resolution. Assigning the defect ensures that the responsible parties are aware of the issue and can take appropriate action.
3. Open:
– The defect remains in the “Open” state while the development team is working on analyzing and fixing the issue. During this stage, developers may collaborate with testers to gather additional information and understand the root cause of the defect.
4. Fixed:
– Once the development team addresses the defect by implementing a fix, the status is changed to “Fixed.” The fix may involve modifying the source code, correcting logic errors, or making other adjustments to eliminate the defect.
5. Verified:
– After the defect is fixed, it is sent back to the testing team for verification. Testers perform testing to ensure that the reported issue has been successfully resolved. If the fix is effective, the defect moves to the “Verified” state.
6. Reopen (Optional):
– If, during verification, testers find that the defect still exists or if the fix has introduced new issues, they may reopen the defect. It returns to the “Open” state for further analysis and resolution.
7. Closed:
– Once the defect has been verified and confirmed as fixed, it is marked as “Closed.” The closed status indicates that the defect has been successfully addressed, and no further action is required.
8. Rejected (Optional):
– In some cases, a defect may be rejected if it is determined that the reported issue is not a valid defect, or if it is intentional behaviour, a duplicate, or a non-reproducible problem. The defect is then marked as “Rejected.”
9. Deferred (Optional):
– If a decision is made to postpone the resolution of a defect to a future release or iteration, it may be marked as “Deferred.” This status indicates that the defect will be addressed in a later development cycle.
10. Duplicate (Optional):
– If a defect is identified as a duplicate of another defect, it may be marked as “Duplicate.” In this case, the original defect is usually kept open, and the duplicate is linked to it.
Throughout the defect life cycle, effective communication and collaboration between development and testing teams are crucial. The defect life cycle helps maintain a systematic approach to defect resolution, ensures proper tracking, and contributes to overall software quality by addressing and eliminating issues in a structured manner.
28. What is the difference between a Bug and a Defect?
Ans: The terms “bug” and “defect” are often used interchangeably in the context of software development and testing, but they can have slightly different interpretations depending on the perspective and industry practices. In many cases, there is no strict distinction, and both terms are used to refer to issues or problems in software. However, some organizations may use these terms with specific meanings. Here’s a general understanding of the terms:
### Bug:

The key is to establish a clear understanding of the terminology within a specific context and ensure consistent usage within a team or project. Ultimately, the goal is to identify, document, and address issues in software to improve its quality and meet user expectations.
29. Explain the concept of Duplicate Defects.
Ans: Duplicate defects refer to multiple defect reports that describe the same or substantially similar issues in a software application. When multiple individuals independently report the same problem, it results in duplicate defect reports. Managing duplicate defects is essential for efficient defect tracking, as it helps avoid redundancy, streamlines the resolution process, and ensures effective communication between development and testing teams.
Here’s an overview of the concept of duplicate defects:
### Key Points:
1. Independent Reports:
– Duplicate defects arise when different users, testers, or stakeholders independently identify and report the same software issue. The reports may come from various sources, such as end-users, internal testers, or automated testing tools.
2. Common Causes:
– Common causes of duplicate defects include multiple users encountering the same problem, testers focusing on the same test scenario, or automated testing tools identifying identical issues during test execution.
3. Efficiency Concerns:
– Managing and resolving duplicate defects can be time-consuming and inefficient. It may lead to redundancy in the defect resolution process, where developers address the same issue multiple times.
4. Defect Tracking Systems:
– Defect tracking systems or issue management tools typically play a crucial role in identifying and handling duplicate defects. These tools often have mechanisms to detect similarities between defect reports and flag potential duplicates.
5. Linking and Cross-Referencing:
– In defect tracking systems, duplicate defects are often linked or cross-referenced to indicate their relationship. This helps teams understand that the reported issues are duplicates and allows them to consolidate efforts during the resolution process.
6. Communication:
– Effective communication between the teams is essential to manage duplicate defects successfully. Testers should be encouraged to check existing defect reports before submitting new ones, and developers need to be aware of reported duplicates.
7. Resolution Consistency:
– Once a duplicate defect is identified, teams need to ensure that the resolution is consistent across all instances of the duplicate. This may involve consolidating information, merging duplicate reports, or providing a unified fix for the identified issue.

2. Defect Recognition Tools:
– Implement defect recognition tools within the defect tracking system to identify potential duplicates based on commonalities in issue descriptions, symptoms, or error messages.
3. Establish Guidelines:
– Establish clear guidelines for defect reporting, emphasizing the importance of providing detailed information. Encourage users and testers to include relevant details, steps to reproduce, and screenshots to minimize ambiguity.
4. Collaborative Platforms:
– Use collaborative platforms or forums where users and testers can discuss and confirm potential duplicates before formally submitting defect reports.
5. Regular Defect Review Meetings:
– Conduct regular defect review meetings where the testing and development teams collaboratively review and discuss defect reports. This can help identify and resolve duplicate defects efficiently.
Effectively managing duplicate defects is crucial for maintaining the efficiency of the defect resolution process and ensuring that development efforts are focused on addressing unique issues. Clear communication, collaboration, and the use of appropriate tools can contribute to a streamlined approach for handling duplicate defects in a software development and testing environment.
### Testing Levels in Manual Testing
30. What is Unit Testing?
Ans: Unit Testing is a software testing technique where individual units or components of a software application are tested in isolation. The primary goal of unit testing is to validate that each unit of the software performs as designed and produces the expected output. Units are typically the smallest testable parts of a program, such as functions, methods, or procedures.
Key characteristics of unit testing:
1. Isolation:
– Unit tests focus on testing a single unit of code in isolation from the rest of the application. This isolation ensures that the behaviour of the unit is examined independently.
2. Automation:
– Unit tests are often automated to enable quick and frequent execution. Automated unit testing frameworks, such as JUnit for Java, NUnit for .NET, or pytest for Python, facilitate the creation and execution of unit tests.
3. Early Detection of Defects:
– Unit testing is typically performed during the development phase, allowing developers to detect and address defects early in the development process. Early detection helps prevent the propagation of defects to subsequent phases.
4. White Box Testing:
– Unit testing is a form of white-box testing, meaning that the tester has knowledge of the internal workings of the unit being tested. Test cases are designed based on an understanding of the code structure and logic.
5. Rapid Feedback:
– Unit tests provide rapid feedback to developers, allowing them to quickly identify and correct issues. This iterative process of writing code, running unit tests, and refining the code contributes to the development of high-quality software.
6. Continuous Integration:
– Unit tests are often integrated into the continuous integration (CI) process, where they are automatically executed whenever code changes are committed. This helps maintain code quality and ensures that new changes do not break existing functionality.
7. Independent Verification:
– Unit testing allows for independent verification of each unit’s correctness. Since each unit is tested in isolation, it helps ensure that units work correctly individually before they are integrated into the larger system.
8. Test Cases:
– Unit test cases are written to cover various scenarios, including normal use cases, boundary conditions, and error conditions. This comprehensive testing helps uncover potential issues and ensures robustness.
9. Refactoring Support:
– Unit tests provide support for refactoring code. Developers can confidently refactor code with the assurance that existing unit tests will catch regressions, ensuring that the intended functionality is not compromised.
10. Documentation:
– Unit tests also serve as a form of documentation for the code. They describe the expected behavior of individual units and provide insights into the code’s functionality.
Example of a simple unit test in a programming language (Java with JUnit):
“`java
import static org.junit.Assert.assertEquals;
import org.junit.Test;
public class CalculatorTest {
@Test
public void testAddition() {
Calculator calculator = new Calculator();
int result = calculator.add(2, 3);
assertEquals(5, result);
}
}
“`
In this example, a unit test is written to verify the correctness of the `add` method in a `Calculator` class. The test ensures that adding 2 and 3 returns the expected result of 5.
Unit testing is an integral part of the software development process, contributing to the development of reliable, maintainable, and bug-free code. It forms the foundation of a comprehensive testing strategy, complementing other testing levels such as integration testing and system testing.
31. Define Integration Testing.
Ans: Integration Testing is a software testing technique that focuses on evaluating the interactions and interfaces between integrated components or systems. The primary goal of integration testing is to ensure that individual components, when combined, function as intended and produce the expected results. It aims to identify defects related to the interfaces and interactions between components, helping to validate the correctness of the integrated system.

3. Staged Integration:
– Integration testing is often conducted in stages, progressing from testing individual components (unit testing) to testing larger groups of integrated components (incremental integration testing) until the entire system is tested.
4. Top-Down or Bottom-Up Approaches:
– Integration testing can be performed using top-down or bottom-up approaches. In the top-down approach, testing begins with the highest-level components, gradually integrating lower-level components. The bottom-up approach starts with the lower-level components, progressively integrating higher-level components.
5. Interfaces and Dependencies:
– Integration tests focus on interfaces and dependencies between components. This includes verifying that input from one component is correctly processed by another, and that the output produced is as expected.
6. Functional and Non-functional Testing:
– Integration testing includes both functional and non-functional testing. Functional testing ensures that integrated components perform their intended functions, while non-functional testing addresses aspects like performance, reliability, and scalability in the integrated environment.
7. Continuous Integration:
– Integration testing is often integrated into continuous integration (CI) processes, where code changes are automatically integrated and tested in a shared environment. This helps identify integration issues early in the development process.
8. Incremental Testing:
– Incremental integration testing involves testing components incrementally as they are added to the system. This allows defects to be detected and addressed early, reducing the complexity of identifying issues in the entire system.
9. Test Stubs and Drivers:
– During integration testing, test stubs and drivers may be used to simulate the behavior of components that are not yet available or to isolate components for testing purposes.
10. Regression Testing:
– Integration testing contributes to regression testing by ensuring that changes or additions to the codebase do not negatively impact the integration points or existing functionality.
11. Scenarios and Use Cases:
– Integration tests are designed to cover various integration scenarios, including typical use cases, boundary conditions, error conditions, and interactions between different components.
Example of an integration test scenario:
Consider an e-commerce application where the integration test verifies the interaction between the shopping cart component and the payment processing component. The test scenario may include:
– Adding items to the shopping cart.
– Initiating the checkout process.
– Verifying that the payment processing component correctly processes the payment information.
