Software testing is a process of verifying and validating the software application. There are different types of software testing like unit testing integration testing system testing etc. Each type of testing has its own significance and purpose. Unit Testing is a process of testing individual units or components of the software to check whether they are working as expected. Integration Testing is a process of testing the interfaces between different modules or components to check whether they are integrated correctly. System Testing is a process of testing the complete system to check whether it meets the requirements.

There are different types of software testing but the most common are functional testing and non-functional testing. Functional testing tests the functionality of the software to make sure it is working as expected. Non-functional testing assesses the performance security and other aspects of the software. There are also other types of testing such as regression testing unit testing and integration testing but functional and non-functional testing are the most common.

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. Testing is a process that should be done throughout the software development life cycle (SDLC). There are various types of tests that can be performed on software which can be broadly classified into two categories: functional testing and non-functional testing.

Functional testing: This type of testing is carried out to check whether the software application is functioning as per the requirement specification documents. Functional testing includes positive testing (to check if the functionality works as expected) and negative testing (to check if the functionality does not work as expected).

Non-functional testing: This type of testing is carried out to check how well the software application performs in terms of different non-functional aspects such as performance scalability security etc.
