What are the main tasks of java testing?

Java testing mainly involves work: 1. Unit testing; 2. Integration testing; 3. Functional testing; 4. Performance testing; 5. Security testing; 6. Continuous integration and automated testing; 7. User Acceptance testing; 8. Regression testing, etc. Detailed introduction: In Java development, testing is a key step to ensure software quality. These test levels and types are often combined in different stages to form a comprehensive testing strategy to ensure the stability, performance and security of the software.

In Java development, testing is a key step to ensure software quality. Java testing mainly involves the following aspects:

1. Unit Testing:

   • Framework: Use unit testing frameworks such as JUnit or TestNG unit test.
   • Goal: Test the smallest unit of code (usually a method or function) to verify whether its behavior is as expected.
   • Tools: JUnit, TestNG, Mockito, etc.

2. Integration Testing:

   • Framework: Use JUnit or other integration testing framework.
   • Goal: Test the integration between multiple modules to ensure they work together.
   • Tools: JUnit, TestNG, Spring Test, etc.

3. Functional Testing:

   • Framework: Use Selenium, Appium and other tools for functional testing of web and mobile applications.
   • Objective: Verify that the entire system functions properly according to specifications.
   • Tools: Selenium, Appium, Cucumber, etc.

4. Performance Testing:

   • Type: Including load testing, stress testing, performance analysis, etc.
   • Objective: Evaluate the performance of the system under different loads and identify potential performance issues.
   • Tools: Apache JMeter, Gatling, etc.

5. Security Testing:

   • Type: Including static code analysis, dynamic security testing, penetration testing, etc.
   • Goal: Discover and fix potential security vulnerabilities to ensure application security.
   • Tools: OWASP ZAP, Burp Suite, FindBugs, etc.

6. Continuous Integration and Automated Testing:

   • Tools: Jenkins, Travis CI, GitLab CI, etc.
   • Goal: Integrate developer code and automate test suite execution, as well as ensure that each commit does not break existing functionality.

7. User Acceptance Testing (UAT):

   • Type: Alpha testing, Beta testing, etc.
   • Objective: Performed by the end user to ensure that the system meets user needs and reaches the expected quality level.

8. Regression Testing:

   • Goal: Ensure that the previous functions still work properly after the code is modified to prevent the introduction of new changes Return error.
   • Tools: JUnit, TestNG, etc.

These test levels and types are usually combined in different stages to form a comprehensive testing strategy to ensure the stability, performance and security of the software.
