所有断言都在断言类别中.
此类别提供了一组用于编写测试的断言方法.只记录失败的断言.
| Sr .No. | 方法&说明 |
|---|---|
| 1 | async() 指示QUnit等待异步操作. |
| 2 | deepEqual() 深递归比较，处理基本类型，数组，对象，正则表达式，日期和函数. |
| 3 | equal() 非严格比较，大致相当于JUnit的assertEquals. |
| 4 | expect() 指定预期在测试中运行的断言数. |
| 5 | notDeepEqual() 反向深度递归比较，处理基本类型，数组，对象，正则表达式，日期和函数. |
| 6 | notEqual() 非严格比较，检查不平等. |
| 7 | notOk() 布尔检查，ok()的反转和CommonJS的assert.ok()，等效于JUnit的assertFalse().如果第一个参数为假，则通过. |
| 8 | notPropEqual() 严格比较对象自身的属性，检查不等式. |
| 9 | notStrictEqual() 严格比较，检查不平等. |
| 10 | ok() 布尔检查，相当于CommonJS的断言.ok()和JUnit的assertTrue().如果第一个参数为真，则通过. |
| 11 | propEqual() 对象自身属性的严格类型和值比较. |
| 12 | push() 报告自定义断言的结果. |
| 13 | strictEqual() 严格的类型和值比较. |
| 14 | throws() 测试回调是否抛出异常，并可选择比较抛出的错误. |
让我们试着在一个例子中介绍上面提到的大部分方法.
<html> <head> <meta charset = "utf-8"> <title>QUnit basic example</title> <link rel = "stylesheet" href = "https://code.jquery.com/qunit/qunit-1.22.0.css"> <script src = "https://code.jquery.com/qunit/qunit-1.22.0.js"></script> </head> <body> <div id = "qunit"></div> <div id = "qunit-fixture"></div> <script> QUnit.test( "TestSuite", function( assert ) { //test data var str1 = "abc"; var str2 = "abc"; var str3 = null; var val1 = 5; var val2 = 6; var expectedArray = ["one", "two", "three"]; var resultArray = ["one", "two", "three"]; //Check that two objects are equal assert.equal(str1, str2, "Strings passed are equal."); //Check that two objects are not equal assert.notEqual(str1,str3, "Strings passed are not equal."); //Check that a condition is true assert.ok(val1 < val2, val1 + " is less than " + val2); //Check that a condition is false assert.notOk(val1 > val2, val2 + " is not less than " + val1); //Check whether two arrays are equal to each other. assert.deepEqual(expectedArray, resultArray ,"Arrays passed are equal."); //Check whether two arrays are equal to each other. assert.notDeepEqual(expectedArray, ["one", "two"], "Arrays passed are not equal."); }); </script> </body></html>验证输出
