Test Design Techniques

The use of structured testing is a crucial step forward in increasing the software quality. After the test plans are written, the test teams formed, and the tools selected, it’s time to develop test cases and start the testing.

So, which test design techniques should you use? How do you decide which tests are most important? What does a good test case look like? How can you reduce the number of tests while increasing coverage? When and how should you use white-box testing to complement black-box techniques?

In a software project‚ the success of testing depends on the test cases used. To reduce the turnaround time and project duration‚ it is important to design an effective set of test cases that enable detection of the maximum number of errors.

This course describes the techniques that are most commonly used for deriving test cases from system documentation. Examples and exercises are used to teach each technique, which is closely examined for its applicability.
