equal( )
A basic equality checking assertion...
Syntax
equal( actual, expected, message );
Parameters
| Parameter | Type | Mandatory | Notes | API Version |
|---|---|---|---|---|
| actual | Variant |  | The actual value. | 1.0 |
| expected | Variant | | The expected value. | 1.0 |
| message | String | | A message stating what the assertion is testing. | 1.0 |
Return Values
| Value | Type | Notes | API Version |
|---|---|---|---|
| <error> | Error | Most likely the parameters are wrong. | 1.0 |
true | Boolean | expected == actual. | 1.0 |
false | Boolean | expected != actual. | 1.0 |
Example
Test("Inequality checks", Test.ANY( ), function() {
// assertions will pass
equal( true, true, "true == true?" );
equal( undefined, null, "undefined == null?" );
equal( null, false, "null == false?" );
equal( "fish", true, "'fish' == true?" );
// assertion will fail
equal( true, false, "true == false?" );
// and for some fun... NaN != NaN, ever!
equal( NaN, NaN, "NaN == NaN?" ); // WAT?!

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...

- 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...
