prompter: What types of tests do we have in software development?

assistant: There are many types of tests in software development, each serving a different purpose. Here are some of the most common types of tests:

1. Unit Tests: These are tests that focus on a small, isolated unit of code, such as a single function or method. They are used to verify that the unit of code behaves correctly in isolation.

2. Integration Tests: These are tests that verify that different units of code work correctly together. They are used to identify issues that may arise when different parts of the system are integrated.

3. System Tests: These are tests that verify that the entire system works correctly, from end to end. They are used to ensure that the software meets all of the requirements and behaves correctly in the context of the overall system.

4. Acceptance Tests: These are tests that verify that the software meets the customer's requirements and expectations. They are often used as a final check before releasing the software to the customer.

5. Regression Tests: These are tests that are run to ensure that changes to the software do not introduce new bugs or issues. They are used to catch regressions that may occur when changes are made to the software.

6. Performance Tests: These are tests that verify that the software performs well under expected load and stress. They are used to identify performance bottlenecks and ensure that the software meets performance requirements.

7. Security Tests: These are tests that verify that the software is secure and does not have vulnerabilities that could be exploited by attackers. They are used to identify and mitigate security risks.

These are just a few examples of the types of tests that are used in software development. The specific tests that are used may vary depending on the project and the development methodology being used.

assistant: Software testing is generally classified into two main broad categories: functional testing and non-functional testing. There is also another general type of testing called maintenance testing.

Functional testing involves the testing of the functional aspects of a software application. When you’re performing functional tests, you have to test each and every functionality. You need to see whether you’re getting the desired results or not.

There are several types of functional testing, such as:

Unit testing
Integration testing
End-to-end testing
Sanity testing
Regression testing
Acceptance testing
Interface testing

Non-functional testing is the testing of non-functional aspects of an application, such as performance, reliability, usability, security, and so on. Non-functional tests are performed after the functional tests.

Non-functional tests are not generally run manually. In fact, it’s difficult to perform this kind of tests manually. So these tests are usually executed using tools.

There are several types of non-functional testing, such as:

Performance testing
Security testing
Load testing
Failover testing
Compatibility testing
Usability testing

Besides performing tests, measuring the effectiveness of the tests is also important, and test coverage tells the effectiveness of your tests.

You can use programs called linters to check if the code of your software project meets the specified coding convention rules. A linter actually saves you a lot of time as manually checking the code written by several developers is a very time-consuming process.
