Topics:

Test() — Define a unit test and it's configuration...
Test Modules — A test module groups one or more unit tests and provides additional lifecycle settings for those tests...
- Test.module() — Allows multiple tests to be grouped together in to modules...
- Module Lifecycle Object — Configure the lifecycle of tests in the module...
Test Modes — Defines the mode in which a unit test is run...
- Test.ANY( ) — The most basic unit test mode...
- Test.EXPECT( ) — Causes the test to fail if it does not generate the specified number of results...
- Test.ASYNCH( ) — Causes a test to keep running until it either passes, fails or times-out...
- Test.APPEND( ) — Appends results to a specific asynchronous test session...
Unit Tests — The unit test function, responsible for performing one or more Test Assertions...
Test Assertions — Assertions are used to perform various tests and annotations within a unit test...
- comment( ) — Adds a comment to the test results...
- ok( ) — A simple state checking assertion...

Test Signals — Signals are used to prematurely terminate Unit Tests...
- REQUIRE( ) — Check whether a test or group of tests have passed. If the requirement fails, a RequireSignal will be sent which terminates the current test and marks it as failed.
- ABORT( ) — Aborts the current test, marking it as failed in the process...
- FINISH( ) — Terminates the test as if it had finished normally...
