一、断言（Assert）

async()
Instruct QUnit to wait for an asynchronous operation.

指导QUnit等待异步操作。

deepEqual()
A deep recursive comparison, working on primitive types, arrays, objects, regular expressions, dates and functions.

用于基本类型，数组，对象，正则表达式，日期和功能的深递归比较。

equal()
A non-strict comparison, roughly equivalent to JUnit’s assertEquals.

非严格的比较，大致相当于JUnit的assertEquals。

expect()
Specify how many assertions are expected to run within a test.

指定有多少断言，将会在运行测试中。

notDeepEqual()
An inverted deep recursive comparison, working on primitive types, arrays, objects, regular expressions, dates and functions.

用于基本类型，数组，对象，正则表达式，日期和功能的倒置深递归比较。

notEqual()
A non-strict comparison, checking for inequality.

非严格的比较，检查是否不平等。

notOk()
A boolean check, inverse of ok() and CommonJS’s assert.ok(), and equivalent to JUnit’s assertFalse(). Passes if the first argument is falsy.

一个布尔检查，ok()和CommonJS的的assert.ok（），并相当于JUnit的assertFalse（）。如果第一个参数是假的，则传递。

notPropEqual()
A strict comparison of an object’s own properties, checking for inequality.

严格的比较对象的自己的属性，检查是否不平等。

notStrictEqual()
A strict comparison, checking for inequality.

严格的比较，检查是否不平等。

ok()
A boolean check, equivalent to CommonJS’s assert.ok() and JUnit’s assertTrue(). Passes if the first argument is truthy.

一个布尔检查，相当于CommonJS的的assert.ok（）和JUnit的assertTrue（）。如果第一个参数是真的，则传递。

propEqual()
A strict type and value comparison of an object’s own properties.

比较一个对象的严格的类型和值。

push()
Report the result of a custom assertion

报告自定义断言的结果

strictEqual()
A strict type and value comparison.

比较严格的类型和值。

throws()
Test if a callback throws an exception, and optionally compare the thrown error.

如果回调抛出一个异常，以及可选比较抛出错误，则测试。

二、异步控制（Async Control）

async()
Instruct QUnit to wait for an asynchronous operation.

QUnit.asyncTest()
DEPRECATED: Add an asynchronous test to run. The test must include a call to QUnit.start().

QUnit.start()
PARTIALLY DEPRECATED: Start running tests again after the testrunner was stopped. See QUnit.stop() and QUnit.config.autostart.

QUnit.stop()
DEPRECATED: Increase the number of QUnit.start() calls the testrunner should wait for before continuing.

QUnit.test()
Add a test to run.

三、回调函数（callbacks）

When integrating QUnit into other tools like CI servers, use these callbacks as an API to read test results.

QUnit.begin()
Register a callback to fire whenever the test suite begins.

QUnit.done()
Register a callback to fire whenever the test suite ends.

QUnit.log()
Register a callback to fire whenever an assertion completes.

QUnit.moduleDone()
Register a callback to fire whenever a module ends.

QUnit.moduleStart()
Register a callback to fire whenever a module begins.

QUnit.testDone()
Register a callback to fire whenever a test ends.

QUnit.testStart()
Register a callback to fire whenever a test begins.

四、配置（configuration）

These methods and properties are used to configure QUnit: to adjust the runtime behaviour directly or extend the QUnit API via custom assertions.

QUnit.assert
Namespace for QUnit assertions

QUnit.config
Configuration for QUnit

QUnit.dump.parse()
Advanced and extensible data dumping for JavaScript

QUnit.extend()
Copy the properties defined by the mixin object into the target object

QUnit.init()
DEPRECATED: Re-initialize the test runner.

QUnit.push()
DEPRECATED: Report the result of a custom assertion

QUnit.reset()
DEPRECATED: Reset the test fixture in the DOM.

五、Test

QUnit.asyncTest()
DEPRECATED: Add an asynchronous test to run. The test must include a call to QUnit.start().
QUnit.module()
Group related tests under a single label.
QUnit.skip()
Adds a test like object to be skipped
QUnit.test()
Add a test to run.

六、实例

在测试页面添加两个文件：

qunit.css

qunit.js

本测试以qunit-1.18.0.css、qunit-1.18.0.js版本

1、基本例子
