What is a test harness
Collection of software and test data configured to perform specific tests on a module of a program by running it under different conditions, comparing actual outputs with expected outputs.
8 of 14
What is volume testing
Tests that the new system works with large volumes of data.

Producing a scaled-down version of the software which is used to show how the new system will work.
11 of 14

Ensures that new software can be used with a variety of hardware specifications and operating systems.
12 of 14
What is simulated environments
Various inputs and outputs can be used to test software in as realistic environment as possible.
13 of 14
What is regression testing
