The performance test interface leverages the script, function, and class-based unit testing

interfaces. You can perform qualifications within your performance tests to ensure correct

functional behavior while measuring code performance. Also, you can run your

performance tests as standard regression tests to ensure that code changes do not break

performance tests.

Determine Bounds of Measured Code

This table indicates what code is measured for the different types of tests.

Type of Test What Is Measured What Is Excluded

Script-based Code in each section of the

script

• Code in the shared
  variables section


• Measured estimate of the
  framework overhead
  Function-based Code in each test function • Code in the following
  functions: setup,
  setupOnce, teardown,
  and teardownOnce


• Measured estimate of the
  framework overhead
