Software Testing Tutorial #19 - What is White Box Testing

[@manoj_mafiosi]

**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.

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

[@comedyman112]

is white box testing reserved only for automated testers?

[@elnino61]

Thanks a lot

[@jagmeetsingh7259]

👌👌👌👌 excellent , found helpful

[@xiamojq621]

Understood sir

[@khetankhobragade71]

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

[@dheenaafc9716]

Vera level uh... 🤣🤣🤣🤣

[@AbrarMehmood-y5v]

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

[@viveksinghbhadauriya7929]

Absolutely Yes

EAT It!

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

Sir your voice is very low.

[@supportmodi_yogi606]

Well explained sir
