About Unit, Integration and Functional Software Testing

Functional, unit and integration testing are types of tests performed on software application to test that the code is functioning the way intended. Functional tests are those that test the features and functions of an application. Unit testing is typically tested by the developer to check the application code. This type of technical testing is not performed at the customer level. It requires knowledge of the application code to test the various code paths and validate that the code is technically sound. Integration testing tests the interfaces between two systems or two pieces of code. Often data is passed between systems and that integration must be tested thoroughly. Again, this is technical testing that typically is not performed by customers or users.
