White-box testing is also called glass testing or open-box testing. In order to perform white-box testing on an application, a tester needs to know the internal workings of the code. The tester needs to have a look inside the source code and find out which unit/chunk of the code is behaving inappropriately. Whitebox testing (also called glass box testing) means choosing test cases with knowledge of how the function is actually implemented. For example, if the implementation selects different algorithms depending on the input, then you should partition according to those domains. 46. White box testing is not called as_____ A. Glass box testing B. Closed box testing C. OPen box testing D. Clear box testing Ans: B. 47. Name the events that will be analyzed, Count the named incidents, Rank the count by frequency using a bar chart & Validate reasonableness of the analysis is called as A. Pareto Analysis B. Cause and Effect White box Testing Benefits: 1. The tester can begin white box testing at an earlier stage. They don’t have to wait for the entire modules to become available. 2. This testing process is more inclusive, provides more coverage into application parts, and hence increases the possibility of testing most of the paths. White box Testing Drawbacks: 1. Jan 23, 2019 · White Box Testing is also called Structural Testing, Clear Box Testing or Low-Level Testing. Black Box Testing is also called Functional Testing, Closed Testing or High-Level Testing. Code Visibility. Black Box Testing focuses on testing the functionality of the software being developed, hence code is not required for it. White Box Testing Advantages of Glass Box Testing: Forces test developer to reason carefully about implementation. Reveals errors in "hidden" code. Spots the Dead Code or other issues with respect to best programming practices. Disadvantages of Glass Box Testing: Expensive as one has to spend both time and money to perform white box testing. Every possibility
2) Grey box testing. 3) Black box testing – also called as functional testing or behavioral testing. 1. White box testing: • White box testing – is done by developers. • This testing is based on knowledge of the internal logic of an application’s code. • Also known as Glass box Testing. White box testing involves looking at the structure of the code. When you know the internal structure of a product, tests can be conducted to ensure that the internal operations performed according to the specification. And all internal components have been adequately exercised. White box testing is also called Structural testing or Glass box correct answer ,you check anyware.why white box testing technique are also called clear and glass box testing ,it must produce correct result to pass,concerned whether or not process worked correctly.based on knowledge of the internal logic of an application's code.tests are based on coverage of code statement,branches,path and conditions
Jun 20, 2017 · While using white-box testing methods, the software engineer can derive test cases that i) guarantee that all independent paths with in a module have been exercised at least once. ii) exercise all logical decisions on their True and False sides.
