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([settingsRefdataRef]) {
	// code and assertions
}

// Define some test data for our unit test
var data = {bar: "fish"};
 
// The test data is passed in as 3rd parameter of the Test() function
// and is accessible via the testData variable
Test("Foo", Test.ANY( ), function() {
	comment( "My first unit test!" );
	// inIn here, 'data' is undefined as the function is re-scoped
	// to the unit test instance it's running within
	equal( "fish", data.bar, "data.bar == 'fish'?" ); // error: data not defined
	equal( "fish", testSettingstestData.bar, "testSettingstestData.bar == 'fish'?" ); // pass
}, data); // <-- test data passed in here
 
// ifIf you wanted to access the settingstestData via a custom named variable,
// specify it's name as the first parameter to the unit test function...
Test("Foo2", Test.ANY( ), function(data) { // <-- custom reference to testData
	comment( "My second unit test!" );
	// nowNow you can access testSettingstestData via 'data' parameter
	equal( "fish", data.bar, "data.bar == 'fish'" ); // pass
	// testSettingsNote that testData variable will still be defined...
    equal( "fish", testSettingstestData.bar, "testSettingstestData.bar == 'fish'" ); // pass
}, data);
