Examples of the various types of testing in Agile development include;
Unit Testing: the testing of an individual unit or group of related units. Usually completed by the programmer to test that the unit he/she has implemented is producing an expected output against a given input.
Functional Testing: testing to ensure that the specified functionality required in the system requirement works.
System Testing: testing to ensure that by putting the software in different environments (e.g., Operating Systems) it still works. System testing is done with full system implementation and environment.
Integration Testing: a group of components are combined to produce output. If software and hardware components have any relation then the interaction between software and hardware is also tested in integration testing.
Regression Testing: Regression testing is the testing after modification of a system, component, or a group of related units to ensure that the modification is working correctly and is not damaging or imposing other modules to produce unexpected results.
Stress Testing: testing to evaluate how system behaves under unfavorable conditions. Testing is conducted at beyond limits of the specifications.
Performance Testing: the testing to assess the speed and effectiveness of the system and to make sure it is generating results within a specified time as in performance requirements.
User Acceptance Testing (UAT): often done by the customer or Prod to ensure that the delivered product meets the requirements and works as the customer expected.
Beta Testing: conducted by a team outside development, or publicly releasing full pre-version of the product which is known as beta version to be tested by end users. The aim of beta testing is to cover unexpected errors.
