The 'describe' keyword in javascript
提问by Aatish Molasi
So I am a newbie in javascript and i had been going through some one else's code and I found this..
所以我是 javascript 的新手，我一直在浏览其他人的代码，我发现了这个..
describe('deviceready', function() {
it('should report that it fired', function() {
spyOn(app, 'report');
app.deviceready();
expect(app.report).toHaveBeenCalledWith('deviceready');
});
});
What I don't understand is:
What exactly does the describekeyword do?
我不明白的是：describe关键字究竟是做什么的？

Describeis not part of Javascript, it is a function defined in the library you used (namely Jasmine)
Describe不是 Javascript 的一部分，它是您使用的库中定义的函数（即 Jasmine）

"A test suite begins with a call to the global Jasmine function describewith two parameters: a string and a function. The stringis a name or titlefor a spec suite - usually what is being tested. The functionis a block of code that implements the suite."
“测试套件以调用全局 Jasmine 函数开始，使用两个参数描述：一个字符串和一个函数。字符串是规范套件的名称或标题- 通常是被测试的内容。该函数是一个 代码块实现套件。”
