This article is devoted to understanding how to derive test cases from a program and also derive coverage metrics for tests undertake. It is much more involved than black-box testing. White-box test design techniques (also called structural or structure-based techniques) are used to derive test cases from an analysis of the program (code). The main aim of white-box testing is to check how the system is performing. Techniques that are used in white-box testing include: 1. It is mainly applicable at lower levels of the testing process. ![]() White-box testing is also known as 'structural testing', 'open box testing' and 'glass box testing'. A software testing technique whereby explicit knowledge of the internal workings of the item being tested are used to select the test data. A test case that makes the condition false also need to be given, such as i = 7 and j = 4. 2.Introduction: White-box/Structure-based measures and its related design techniques are described in BS7925-2 standard. White box testing is a form of application testing that provides the tester with complete knowledge of the application being tested, including access to source. The tester also needs to validate the internal structure of the item under consideration along with the output.Ĭonsider this example: If (i 7) do this else do that If the test case i= 4 and j= 8 is given as input, only the true condition is met and the code executed. The tester detects all logical, design and typographical errors. The objective is to ensure that each and every line of the code is tested. The tester is required to know the internal workings of the code. Definition: White-box Testing is a type of testing method where the software tester has knowledge of internal structure and code in the system.ĭescription: White-box Testing is a type of testing method where the tester (a developer testing the application) is aware of the system internals. ![]()
