What type of testings are available

• Functional Every functionality of the system is tested by providing appropriate input, verifying the output, and comparing the actual results with the expected results.

• White box testing When we have all information about it and want to make code better.

• Black box testing When we test software from scratch, we don't have information or knowledge about the application, and we test it like a final customer.

• Gray box testing When we know something about — helpful to find o

  bugs that user would not know about it.

• Regression testing Searching for bugs (with test documentation) — used mostly.

When to test ?

• Developers testing during completing tasks (important: check quality of code: includes unit testing and component architecture testing - this way we ensure code will work when integrated)

• Internal testing of completed tasks (testers- project lead/other and developers tests tasks in QA while they keep in mind user experience to ensure that development is going on according to business goals
