Software Testing Tutorial #19 - What is White Box Testing 

**Software Testing Tutorial #19 - What is White Box Testing - Notes** **Comparing with Black Box Testing:** - Recap of black box testing where only inputs and outputs are focused. - White box testing focuses on internal logic and code understanding. **White Box Testing Explained:** - Also known as clear box testing, structural testing, or glass box testing. - Analogy of an open "box" that exposes internal mechanisms and code. - Unlike black box testing, white box testing comprehends system's implementation. **Analogy with Calculator:** - In black box, interact with calculator for output, no knowledge of internals. - In white box, open calculator's "box," analyze internal code. - Craft test cases to evaluate logic and structure of calculator's code. **Testing Techniques in White Box Testing:** 1. **Statement Coverage**: Ensure each code statement is executed at least once. 2. **Branch Coverage**: Guarantee every branch or decision point is taken. 3. **Condition Coverage**: Focus on code conditions and test all outcomes. 4. **Loop Testing**: Verify behavior within loops and iterated sections. 5. **Path Testing**: Examine different execution paths and test each one. **Application of White Box Testing:** - Often done during unit testing and integration testing. - Developers write unit tests to validate implemented logic. - Ensures seamless integration and collective functionality in integration testing. **Advantages and Conclusion:** - White box testing allows scrutiny of system's internals and logic. - Validates implementation quality, identifies potential bugs. - Ensures reliable and robust system performance. - It's an essential part of software testing to ensure comprehensive quality.

Few weaks ago i starded "SW tester" course according ISTQB and your courses give me the advice in my study, many thanks, John

Thank you so much for making videos like this accessible to all, this is awesome.

very good presentation sir. plz do some focus on mic quality. thank you

thank you so much for sharing your knowledge.

Very Detailed. Thank you

Thank you mate, very clear and helpful

Excellent sir 🙏understood very well

going to subscribe really liked your content 👍🏻✅

Well explained sir

Sir different names of white box testing unit, cler, glass, transperent,code, structural, open right or rong

Good teaching

Thank you sir

👌👌👌👌 excellent , found helpful

Thanks a lot

is white box testing reserved only for automated testers?

Understood sir

Sir please make a interview vedios on manual , Api , database and Unix testing , I like the ways you explains

I don't have bachelor degree in IT or any other related but if I understand the testing than Can I get software testing job

Vera level uh... 🤣🤣🤣🤣

Sir your voice is very low.

i think whitebox testing is a really bad idea. 1. you lock the implementation. i can no longer change (improve) the code without also having to change the test 2. the test is *way* more complex, meaning it now needs tests itself (because if i can trust complex code right away i need no tests in the first place) 3. the test itself is harder to read because it's not clear which variable has which value for which reason

EAT It!

Good Presentation
