The primary goal of software testing is to ensure that the software meets its requirements, as defined by the stakeholders. This involves testing the software to identify any defects or deviations from the requirements.

The two main types of software testing are functional testing and non-functional testing. Functional testing verifies that the software meets its functional requirements, while non-functional testing verifies that the software meets its non-functional requirements, such as performance, security, and usability.

Unit testing tests individual units of code, such as functions or methods, to ensure that they work as expected. Integration testing tests how different units of code work together to ensure that the overall software system works as expected.

White-box testing is a type of testing that is based on the internal structure of the software. It involves examining the code to identify potential defects or vulnerabilities.

Black-box testing is a type of testing that is based on the external behavior of the software. It involves testing the software without examining its internal structure.

Static testing is a type of testing that is performed before the software is executed. It involves examining the source code or other artifacts to identify potential defects or vulnerabilities.

Dynamic testing is a type of testing that is performed after the software is executed. It involves running the software and observing its behavior to identify potential defects or vulnerabilities.

A test case is a set of inputs, expected outputs, and preconditions for a test. It defines the conditions under which a test will be performed and the expected results of the test.

A test suite is a collection of test cases that are used to test a particular software system or component.

A test plan is a document that describes the scope, objectives, and schedule of a testing project. It also defines the resources that will be used to conduct the testing project.

A test report is a document that summarizes the results of a testing project. It includes information about the tests that were performed, the defects that were found, and the overall status of the testing project.

A bug is a mistake in the code that can cause the software to behave incorrectly. A defect is a deviation from the requirements, which can be caused by a bug or by other factors, such as a misunderstanding of the requirements or a change in the requirements.

The purpose of a quality assurance audit is to assess the effectiveness of the software testing process. It involves examining the testing process, the test cases, and the test results to identify any areas where the testing process can be improved.

Quality assurance is proactive, meaning that it is focused on preventing defects from occurring in the first place. Quality control is reactive, meaning that it is focused on identifying and fixing defects after they have occurred.

The role of a software tester is to ensure that the software meets its requirements. This involves testing the software to identify any defects or deviations from the requirements.
