Jasmine 编写 JavaScript 测试用例
1,下载Jasmine 包，主要包括如下三个文件：
1>,jasmine-html.js,jasmine.css,jasmine.js
2>,编写测试用例,代码如下：
describe("Examples of Jasmine suite", function() {
//List 1
describe("This is an exmaple suite", function() {
it("contains spec with an expectation", function() {
expect(true).toBe(true);
expect(false).toBe(false);
expect(false).not.toBe(true);
});
});
//List 2
describe("Test suite is a function.", function() {
var gVar;
it("Spec is a function.", function() {
gVar = true;
expect(gVar).toBe(true);
});
it("Another spec is a function.", function() {
gVar = false;
expect(gVar).toBe(false);
});
});
//List 3
describe("This is an exmaple suite", function() {
it("contains spec with an expectation", function() {
var num = 10;
expect(num).toEqual(10);
});
});
//List 4
describe("The 'toBe' matcher compares with ===", function() {
it("and has a positive case ", function() {
expect(true).toBe(true);
});
it("and can have a negative case", function() {
expect(false).not.toBe(true);
});
});
//List 5
describe("Included matchers:", function() {
it("The 'toBe' Matcher", function() {
var a = 3.6;
var b = a;
expect(a).toBe(b);
expect(a).not.toBe(null);
});
describe("The 'toEqual' matcher", function() {
it("works for simple literals and variables", function() {
var a = "varA";
expect(a).toEqual("varA");
});
it("Work for objects", function() {
var obj = {
a: 1,
b: 4
};
var obj2 = {
a: 1,
b: 4
};
expect(obj).toEqual(obj2);
});
});
it("The 'toBeDefined' matcher ", function() {
var obj = {
defined: 'defined'
};
expect(obj.defined).toBeDefined();
expect(obj.undefined).not.toBeDefined();
});
});
//List 6
describe("An example of setup and teardown", function() {
var gVar;
beforeEach(function() {
gVar = 3.6;
gVar += 1;
});
afterEach(function() {
gVar = 0;
});
it("after setup, gVar has new value.", function() {
expect(gVar).toEqual(4.6);
});
it("A spec contains 2 expectations.", function() {
gVar = 0;
expect(gVar).toEqual(0);
expect(true).toEqual(true);
});
});
//List 7
describe("A spec", function() {
var gVar;
beforeEach(function() {
gVar = 3.6;
gVar += 1;
});
afterEach(function() {
gVar = 0;
});
it("after setup, gVar has new value.", function() {
expect(gVar).toEqual(4.6);
});
it("A spec contains 2 expectations.", function() {
gVar = 0;
expect(gVar).toEqual(0);
expect(true).toEqual(true);
});
describe("nested describe", function() {
var tempVar;
beforeEach(function() {
tempVar = 4.6;
});
it("gVar is global scope, tempVar is this describe scope.", function() {
expect(gVar).toEqual(tempVar);
});
});
});
//List 8
xdescribe("An example of xdescribe.", function() {
var gVar;
beforeEach(function() {
gVar = 3.6;
gVar += 1;
});
xit(" and xit", function() {
expect(gVar).toEqual(4.6);
});
});
});
3>,编写一个List.html文件作为调用Jasmine 和测试用例的入口文件,代码如下：
<html>
<head>
<title>Jasmine Spec Example</title>
<link rel="shortcut icon" type="image/png" href="lib/jasmine-1.3.1/jasmine_favicon.png">
<link rel="stylesheet" type="text/css" href="lib/jasmine-1.3.1/jasmine.css">
<script type="text/javascript" src="lib/jasmine-1.3.1/jasmine.js"></script>
<script type="text/javascript" src="lib/jasmine-1.3.1/jasmine-html.js"></script>
<script type="text/javascript" src="spec/Lists.js"></script>
<script type="text/javascript">
var jasmineEnv = jasmine.getEnv();
var htmlReporter = new jasmine.HtmlReporter();
jasmineEnv.addReporter(htmlReporter);
jasmineEnv.specFilter = function(spec) {
return htmlReporter.specFilter(spec);
};
window.onload = function() {
jasmineEnv.execute();
};
</script>
</head>
<body>
</body>
</html>
4>,在浏览器打开List.html文件,即可用查看 Lists.js 文件编写的测试用例的所有的执行结果报告，如果所测试用例执行错误，则会在界面上提示是哪个测试用例执行报错，如下图：
