Software testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test. Software testing can also provide an objective independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include but are not limited to the process of executing a program or application with the intent of finding software bugs (errors or other defects).
There are various types of software testing such as unit testing integration testing system testing and acceptance testing. Unit testing is a level of software testing where individual units/components of a software are tested. Integration testing is a level of software testing where integrated units/components are tested as a group. System testing is a level of software testing where complete and integrated software is tested. Acceptance testing is a level of software testing where final user criteria are verified to ensure that the system meets its needs.

There are various types of software testing but they can broadly be classified into two categories:
1) Static testing - This type of testing is based on reviewing documents that describe the code or application without executing it. For example reviews walkthroughs and inspections.
2) Dynamic testing - This type of testing involves executing code or applications. For example unit testing integration testing system testing and acceptance testing.

Software testing can also provide an objective independent view of the software to allow the business to appreciate and understand the risks of software implementation. Test techniques include but are not limited to the process of executing a program or application with the intent of finding software bugs (errors or other defects) and verifying that the software product is fit for purpose.
There are different types of software testing such as unit testing integration testing system testing and acceptance testing. Unit testing is done at the developer level and tests individual units of code. Integration testing is done after unit testing and it tests how well units of code work together. System testing is done after integration testing and it tests an entire system to check if all components work together as expected. Acceptance testing is done by customers or end-users to check if a system meets their needs and expectations.
