Principles of Testing

• Each test case must address one requirement (or a part of it)
• Preparation of test cases should begin a lot earlier than their execution
• Pareto principle: 80% of the errors will involve 20% of the code
• Testing should start from small units and end with the complete system
• Testing is never complete
• Effective testing can only be performed by a third party
• Testing should involve black-box and black-box techniques
• Ideally, testing should automated, so that it can be executed after every software modification
