An overview of test design techniques in software development. Deriving test cases directly from a requirement specification or black box test design. The concept behind this technique is that test case of a representative value of each class is equal to a test of any other value of the same class. There are many different test case design techniques used to test the functionality and various features of your software. According to the istqb blog, test design also involves creating and writing test suites for testing a software, but will require specificity and detailed input. Test case design techniques are a significant part of software testing as they are directly responsible for success of software testing.
