The unit test function, responsible for performing one or more Test Assertions...

 

Syntax

The scope of unit test functions is manipulated before a test runs, so you cannot reference variables defined in the function's scope chain (closures will not work either).

If you want to reference variables external to the Unit Test function, pass them in via a settings object defined in the associated Test() invocation (see Example section below).

function() {
	// code and assertions
}

Parameters

The unit test function has no parameters, but a number of variables and properties are available within it – see Notes below for details.

Return value

The return value is not processed.

Notes

Within the unit test, the following variables and properties are available:

Property / VariableTypeTest.APPEND( ) modeAny other modeAPI Version
_globalObject

A reference to the global object (not scope).

This variable is defined by Test API and is thus safer to use within tests than the equivalent global defined by Util API.

1.0
modulePathStringThe modulePath that the test is running in – see Test.module() for more information.1.1
moduleSettings

Object

Undefined

The settings associated with the modulePath, if specified in the Module Lifecycle Object.

If the module doesn't have settings, moduleSettings will have a value of undefined.

1.1
this.settingsVariant

The settings associated with the Test.ASYNCH( ) that initiated the current asynchronous test session.

Same as testSettings below.1.0
testSettingsVariantThe settings associated with the current unit test.1.0
testNameStringThe name of the current unit test.1.0
testModeObject

An object describing the mode in which the test is being run – for more information see Test API - Dev Notes.

Example

var mySettings = {bar: "fish"};
Test("Foo", Test.ANY( ), function() {
	comment( "My first unit test!" );
	equal( "fish", testSettings.bar, "testSettings.bar == 'fish'?" );
}, mySettings);

  • 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 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...
    • hasNative( ) — Assert presence of a native property on the global object...
    • hasFunction( ) — Check if a context has a function property, optionally with specified number of formal parameters...
    • equal( ) — A basic equality 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...
