Functional testing is a type of software testing that verifies if the software functions as intended by checking its features and capabilities against specified requirements.
A checklist is a structured list of items, tasks, or criteria used to ensure that all necessary steps or requirements are completed during a process, such as software testing. It helps testers verify that all aspects of the testing process are covered and nothing is overlooked.
**Test Cases for Vendor Machine Inputs:**
1. **Boundary Value Analysis:**
- Test Case 1: Input 50 (valid input)
- Test Case 2: Input 49 (invalid input, below boundary)
- Test Case 3: Input 51 (invalid input, above boundary)
2. **Equivalence Partitioning:**
- Test Case 4: Input 50 (valid input for Pepsi)
- Test Case 5: Input 50 (valid input for Cock)
- Test Case 6: Input 50 (valid input for 7Up)
- Test Case 7: Input 0 (invalid input, below valid range)
- Test Case 8: Input 100 (invalid input, above valid range)
3. **Invalid Inputs:**
- Test Case 9: Input -10 (invalid negative input)
- Test Case 10: Input "abc" (invalid non-numeric input)
Testing methodology refers to the systematic approach and set of principles used to plan, execute, and evaluate software testing processes. It includes defining testing objectives, selecting appropriate testing techniques, and establishing criteria for success to ensure software quality and reliability.
Response time is the total time taken from when a request is made until the first response is received, including processing time and network latency.
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.
