Software Testing first week course essays

This week is the first lesson, a classic question at the beginning of the course: What is software testing? Software testing is the process of verifying whether it meets the required requirements or clarifies the difference between the expected and actual results, either by manual operation or by the automatic operation of the software.

Purpose of the test:1. Discover some development risks that can be avoided by testing.

2. Implement tests to reduce the risk that is found.

3. Determines when the test can end.

4. Consider testing as a standard project during the development of a project.

Classification of software tests: black box test, white box test

Black box testing: black-box testing is also known as functional testing, and it is tested to see if each feature is working properly. In the test, the program as a black box can not be opened, regardless of the internal structure of the program and internal characteristics of the case, in the program interface testing, it only checks whether the program function in accordance with the requirements of the specification of the normal use, the program can properly receive input data and produce the correct output information. Black box testing focuses on the external structure of the program, regardless of the internal logical structure, mainly for the software interface and software function testing.

White Box testing: white-box testing is also called structural testing, transparent box testing, logic-driven testing, or code-based testing. White box testing is a test case design method, the box refers to the software being tested, the white box refers to the box is visible, you know what the inside of the box and how it works. " White Box " method to fully understand the internal logical structure of the program and to test all logical paths. the " White box " method is a poor lift path test. When using this scenario, the tester must examine the internal structure of the program, starting with the logic of the checker and drawing the test data.
