// A test suite begins with a call to the global function `suite` with two parameters:
// a string and a function.
// The string is a name or title for a spec suite – usually what is being tested.
// The function is a block of code that implements the suite.
suite('String matching', function(suite) {
var text;
// To help a test suite DRY up any duplicated setup code, provides
// the global `setup` functions.
// As the name implies the `setup` function is called once.
// You can store data in `suite` Object, or define necessary variables.
// Code from body of the function will be presented in UI.
setup(function() {
suite.text = 'Hello world';
text = 'Hello world';
});
// Benchmark are defined by calling the global function `bench`,
// which, like `suite` takes a string and a function.
// The string is the title of the test and the function is the test
bench('String#match', function() {
!! text.match(/o/);
});
bench('RegExp#test', function() {
!! /o/.test(suite.text);
});
// Async benchmark.
// Calls to `bench` can take an optional single argument, Deferred object,
// method .resolve() should be called when the async work is complete.
bench('Async#test', function(deferred) {
setTimeout(function() {
deferred.resolve();
}, 100);
},
