Regression testing is the process of verifying that previously developed and tested software still performs after a change, such as enhancements or bug fixes. Retesting, on the other hand, involves testing a specific defect after it has been fixed to ensure that the issue has been resolved.
To parameterize a test with a database table or an Excel sheet, you can follow these steps:
1. **For Database Table:**
- Establish a connection to the database using a connection string.
- Write a SQL query to fetch the required data.
- Execute the query and store the results in a variable or data structure.
- Use the fetched data in your test scripts by referencing the variable.
2. **For Excel Sheet:**
- Use a library or tool (like Apache POI for Java, or pandas for Python) to read the Excel file.
- Load the specific sheet and range of cells containing the test data.
- Store the data in a variable or data structure.
- Reference this data in your test scripts as needed.
Make sure to handle any necessary data conversions and error handling as per your testing framework.
Testing in an Uncontrolled Environment refers to testing conducted without any predefined conditions or controls, leading to unpredictable results. In contrast, Testing in an Abnormal Environment involves testing under specific conditions that deviate from the norm, such as system failures or unexpected inputs, to assess how the system behaves in those scenarios.
Web-based testing is the process of testing applications that run on web browsers. To manually test a web application in real time, follow these steps:
1. **Understand Requirements**: Review the application requirements and specifications.
2. **Prepare Test Cases**: Create detailed test cases based on the requirements.
3. **Set Up Test Environment**: Ensure the testing environment is ready, including browsers and devices.
4. **Perform Functional Testing**: Test all functionalities to ensure they work as expected.
5. **Check Usability**: Evaluate the user interface and user experience.
6. **Test Compatibility**: Verify the application works across different browsers and devices.
7. **Conduct Performance Testing**: Assess the application's performance under various conditions.
8. **Report Bugs**: Document any defects found and report them to the development team.
9. **Retest**: Once bugs are fixed, retest the application to ensure issues are resolved.
Follow this procedure to ensure comprehensive testing of the web application
To prepare a traceability matrix for a web application, follow these steps:
1. **Identify Requirements**: List all the requirements of the web application, including functional and non-functional requirements.
2. **Map Test Cases**: For each requirement, identify and list the corresponding test cases that validate it.
3. **Create the Matrix**: Organize the information in a table format with requirements on one axis and test cases on the other.
**Example of a Traceability Matrix:**
| Requirement ID | Requirement Description | Test Case ID | Test Case Description |
|----------------|-------------------------|--------------|-----------------------|
| REQ-001 | User login functionality| TC-001 | Test valid login |
| REQ-001 | User login functionality| TC-002 | Test invalid login |
| REQ-002 | Password reset feature | TC-003 | Test password reset |
**Use of Traceability Matrix**: It ensures that all
To ensure all test cases are covered in an application, you can use a combination of techniques:
1. **Requirements Traceability Matrix (RTM)**: Map each requirement to its corresponding test cases to ensure all are covered.
2. **Test Case Review**: Regularly review test cases with stakeholders to confirm coverage.
3. **Code Coverage Tools**: Use tools to analyze code coverage metrics, ensuring all code paths are tested.
4. **Test Case Execution Reports**: Track executed test cases and their results to identify any gaps in coverage.
5. **Exploratory Testing**: Conduct exploratory testing sessions to uncover any untested areas.
1. Verify the Google text field is present and enabled.
2. Check that the Google text field accepts input.
3. Test inputting various types of text (e.g., letters, numbers, special characters).
4. Validate the maximum character limit for the Google text field.
5. Ensure the "Google Search" button is present and enabled.
6. Verify the "I'm Feeling Lucky" button is present and enabled.
7. Test clicking the "Google Search" button with valid input.
8. Test clicking the "I'm Feeling Lucky" button with valid input.
9. Check the behavior when the Google text field is empty and the "Google Search" button is clicked.
10. Check the behavior when the Google text field is empty and the "I'm Feeling Lucky" button is clicked.
11. Validate the page loads correctly with no errors.
12. Test the responsiveness of the Google text field and buttons on different screen sizes.
13. Verify the text field clears after submitting a search.

A Traceability Matrix is a document that maps and traces user requirements with test cases. It is used to ensure that all requirements are covered by tests, helping to identify any gaps in testing and ensuring that all functionalities are validated. The architecture typically includes columns for requirement IDs, requirement descriptions, test case IDs, test case descriptions, and status of the test cases (e.g., pass, fail, not executed).
The Whitebox Testing section on takluu.com is designed for QA professionals, testers, and developers who want to master the internal testing techniques crucial for delivering high-quality software. Whitebox testing, also known as structural or glass-box testing, involves examining the internal logic, code structure, and workflows to ensure thorough test coverage and bug detection.
This category covers essential concepts such as code coverage metrics (statement, branch, path coverage), control flow testing, data flow testing, unit testing frameworks, and debugging techniques. You’ll also learn about writing effective test cases, identifying edge cases, and using automation tools that support whitebox testing.
Whitebox testing is vital in detecting hidden errors early in the development cycle, improving code quality, and facilitating continuous integration and deployment. This section provides practical interview questions and detailed explanations to help you understand how whitebox testing differs from blackbox testing and when to apply each.
You will also find scenario-based questions frequently asked in QA and software developer interviews that test your understanding of testing methodologies, code instrumentation, and test-driven development (TDD).
Whether you’re preparing for roles such as QA Engineer, Software Tester, or Automation Engineer, this section equips you with the knowledge and skills to perform effective whitebox testing and confidently answer related interview questions.
At Takluu, we focus on practical learning, ensuring you can apply whitebox testing techniques in real projects and succeed in your career journey.
