What are the common testing techniques?

Common testing technologies include black box testing, white box testing, gray box testing, functional testing, performance testing, security testing, automated testing and continuous integration. Detailed introduction: 1. Black box testing is a testing method that does not care about the internal structure and implementation details of the system under test, but only focuses on the input and output of the system. Testers design test cases based on requirements and specification documents, and input a Combine reasonable test data to verify whether the system's output meets expectations; 2. White-box testing is a testing method that focuses on the internal structure and implementation details of the system under test, etc.

There are many common testing techniques. Below I will introduce some common testing techniques, including black box testing, white box testing, gray box testing, and functional testing. Testing, performance testing, security testing, automated testing and continuous integration.

1. Black Box Testing:

Black box testing is a testing method that does not care about the internal structure and implementation details of the system under test, but only focuses on the input of the system. and output. Testers design test cases based on requirements and specification documents, and verify whether the system output meets expectations by inputting a reasonable set of test data. Black box testing mainly focuses on the functions, interface, user experience and other aspects of the system.

2. White Box Testing:

White box testing is a testing method that focuses on the internal structure and implementation details of the system under test. Testers can view the source code, logic and data structure of the system, design test cases, and verify whether each branch and path of the system is correct. White box testing mainly focuses on the logical correctness and code coverage of the system.

3. Gray Box Testing:

Gray box testing is a combination of black box testing and white box testing. It focuses on both the input and output of the system and the internals of the system. Structural and implementation details. When designing test cases, testers can partially understand the internal structure of the system to better design test cases. Gray box testing mainly focuses on the functions, performance, security and other aspects of the system.

4. Functional Testing:

Functional testing is a testing method that mainly focuses on whether the functions of the system meet the requirements and specification documents. Testers design test cases and verify whether the system functions normally by inputting a set of reasonable test data. Functional testing can include functional testing under normal circumstances, boundary condition testing, functional testing under abnormal circumstances, etc.

5. Performance Testing:

Performance testing is a testing method that mainly focuses on the performance of the system under different loads. Testers design test cases and verify whether the system's response time, throughput, concurrency and other indicators meet the requirements by simulating various load conditions. Performance testing can include load testing, stress testing, stability testing, etc.

6. Security Testing:

Security testing is a testing method that mainly focuses on the security of the system. Testers simulate various attack methods to verify whether the system's security protection capabilities meet requirements. Security testing can include vulnerability scanning, penetration testing, code auditing, etc.

7. Automation Testing:

Automated testing is a testing method that uses automation tools and scripts to perform test tasks. Testers write test scripts and execute the test scripts through automated tools to verify whether the system's functions and performance are normal. Automated testing can improve testing efficiency and accuracy.

8. Continuous Integration:

Continuous integration is a development process that mainly focuses on the integration and testing of code. After developers submit code each time, the build and testing process is automatically triggered to verify the quality and stability of the code. Continuous integration can improve team collaboration efficiency and code quality.

In addition to the common testing technologies introduced above, there are also some other testing technologies, such as regression testing, interface testing, security testing, compatibility testing, etc. Different testing technologies are suitable for different testing scenarios and goals, and testers can choose appropriate testing technologies according to specific needs. At the same time, the selection of testing technology also needs to consider factors such as testing resources, time and cost.
