Jasmine Writing JavaScript Test Cases

1, download Jasmine package, mainly includes the following three files:

1>,jasmine-html.js,jasmine.css,jasmine.js

2>, write the test case with the following code:

Describe ("Examples of Jasmine Suite", function () {//list 1 describe ("This was an exmaple suite", function () {            It ("contains spec with an expectation", function () {expect (true).

3>, write a list.html file as a portal file that calls Jasmine and test cases, with the following code:

4>, open the list.html file in the browser, you can use the view Lists.js file to write the test case of all the results of the execution report, if the test case execution error, you will be prompted on the interface which test case execution errors, such as:
