Types of Software Testing , Testing Types

Based on the focus areas, testing types are defined: 

• • • Functional Testing
    • Non- Functional Testing
    • Structural Testing
    • Re-testing 
    • Regression Testing

1) Functional Testing:

Functional testing is a software testing technique that tests features and functionality of the Software under test, by providing inputs and evaluating outputs. Please refer Functional testing for in depth details. 

2) Non Functional Testing:

Non-functional Testing is the testing of a software application or system for its non-functional requirements: the way a system operates, rather than specific behaviour of that system, its performance, reliability, load testing.Please refer Non-functional Testing for in depth details. 

3) Structural Testing:

Structural testing is the type of testing carried out to test the structure of code. It is also known as White Box testing or Glass Box testing. This type of testing requires knowledge of the code, usually done by the developers. It is also called white box testing or glass box testing.Please refer  Structural testing for in depth details. 

4) Re Testing:

Re-testing or confirmation testing  is testing a defect fix to confirm that the original defect has been successfully removed.

Please refer  Re Testing for in depth details. 

5) Regression Testing

Regression testing is the repeated testing of an already tested program, after modification, to discover any defects introduced or uncovered as a result of the change.

Please refer  Regression testing  for in depth details.
