Software testing methods презентация

Black box testing. Testing software based on functional and business requirements at operating it without knowledge of the internal structure or program source code. A tester tests a product so as an end-user would work with it at launching and operating it.
White box testing. The tester uses his understanding of source code and access the code to develop and execute test cases. This method tests the architecture of the system.

Development Testing is a software development process that involves synchronized application of a broad spectrum of defect prevention and detection strategies in order to reduce software development risks, time, and costs.

What if prototype seems wrong?
Every person may have different opinion
Fight only serious issues
Be on “user” point of view; check with other users
Be very polite
UI designer opinion will often win anyway
