As a sign of the end of software testing, the error intensity curve drops to a predetermined level.

Software testing comes along with the creation of software. In the early software development process, the software was small in scale and low in complexity. The software development process was chaotic and quite random. The meaning of testing was relatively narrow. Developers equated testing with "debugging", with the purpose of correcting known errors in the software. Failures often leave this part of the work to the developers themselves.

There is very little investment in testing, and testing intervention is also late. Testing is often carried out until the code is formed and the product is basically completed. By the early 1980s, the software and IT industries had entered a period of great development. Software was becoming larger and more complex, and the quality of software was becoming more and more important.

Software testing principles:

Before testing computer software, you must first follow the software testing principles, that is, the principle of incompleteness. The principle of incompleteness means that if the test is incomplete and there are many parts involving the immunity principle in the testing process, it can be of certain help to software testing. Software testing has a certain degree of immunity from such factors.

The test content that testers can complete is directly proportional to their immunity. If you want to make software testing smoother and more effective, you must first follow these principles and integrate them throughout the entire development process. , continuous testing, rather than a one-time full test.
