Planning is one of main activities of software testing. Depending on formality of our test process, we have to create detailed test plans with strict template or simple check list on a paper. In any case, we must remember that planning is an endless activity. At least we have to plan for the whole project life cycle. We can’t create a test plan at the begin of the project, print it and have a successful test process. Test plan must be corrected and updated at every turn.
