notSimilarTo( )

A deep dissimilarity spotting assertion...

Syntax

notSimilarTo( actual, unexpected, message );

Parameters

Parameter	Type	Notes	API Version
actual	Variant	An object containing the actual values.	1.3
unexpected	Variant	An object containing what you don't expect to find in the actual object.	1.3
message	String	A message stating what the assertion is testing.	1.3

Return Values

Value	Type	Notes	API Version
<error>	Error	Most likely the parameters are wrong.	1.3
`true`	Boolean	The actual value did not contain anything unexpected.	1.3
`false`	Boolean	The actual value contained unexpected things.	1.3

Notes

Unlike notDeepEqual( ), notSimilarTo( ) only investigates enumerable properties in the expected object.

Property values in the expected object have the following effects:

Expected Value	Notes	API Version
`null`	See `Test.FOUND` below.	1.3
`Test.FOUND`	The assertion will fail if a property of the same name is found in the same place in the actual object.	1.4
`undefined`	See `Test.NOT_FOUND` below.	1.4
`Test.NOT_FOUND`	The assertion will fail if a property of the same name is not found in the same place in the actual object.	1.4
*Any other value*	The assertion will fail if a property of the same name and value is found in the same place in the actual object.	1.3

Properties in the actual value that aren't listed in the unexpected value are ignored.

The checks will go to a maximum of 10 levels deep.

Example

Test("Dissimilarity checks", Test.ANY( ), function() {
	// assertions will pass
	notSimilarTo( {a:1, c:3}, {b:Test.FOUND}, "not actual.b found?" );
	notSimilarTo( {a:1, c:3}, {a:Test.NOT_FOUND}, "not actual.a not found?" );
	notSimilarTo( {a:1, c:3}, {a:2}, "not actual.a == 2?" );
	// assertion will fail
	notSimilarTo( {a:1, c:3}, {a:Test.FOUND}, "not actual.a found?" );
	notSimilarTo( {a:1, c:3}, {b:Test.NOT_FOUND}, "not actual.b not found?" );
	notSimilarTo( {a:1, c:3}, {a:1}, "not actual.a == 1?" );
});

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...
- 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...

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...
