Test Execution Process

The preparation to test the application is now over. The test team should next plan the execution of the test on the application. In this section, we will see how test execution is performed.

Stages of Testing

Three passes
Tests on the application are done on stages. Test execution takes place in three passes or sometimes four passes depending on the state of the application. They are:

Pre IST or Pass 0: This is done to check the health of the system before the start of the test process. This stage may not be applicable to most test process. Free form testing will be adopted in this stage.

Comprehensive or Pass 1: All the test scripts developed for testing are executed. Some cases the application may not have certain module(s) ready for test, hence they will be covered comprehensively in the next pass. The testing here should not only cover all test cases but also business cycles as defined in the application.

Discrepancy or Pass 2: All Test scripts that have resulted in a defect during the comprehensive pass should executed. In other words, all defects that have been fixed should be retested. Function points that may be affected by the defect should also be taken up for testing. Automated test scripts captured during the pass one are used here. This type of testing is called as Regression testing. Defects that are not fixed will be executed only after they are fixed.

Sanity or Pass 3: This is the final round in the test process. This is done either at the client's site or at Same Organization depending on the strategy adopted. This is done in order to check if the system is sane enough for the next stage i.e. UAT or production as the case may be under a isolated environment. Ideally the defects that are fixed from the previous pass are checked and freeform testing done to ensure integrity is conducted.
