#"在摩卡咖啡中是否有特殊含义? describe和it实际做什么?抱歉，找不到describe和it

Does '#' has special meaning in Mocha? What does describe and it actually do? sorry not found document for describe and it

推荐答案

describe和it遵循称为BDD的模式，表示行为驱动开发".它只是定义了一个接口，使您对编写测试的方式有所不同，至少应该如此.嵌套describe还可以按功能对测试进行分组，并且生成的报告对此具有可读性".

describe and it follows a pattern called BDD, which means "Behaviour Driven Development". It just defines an interface that makes you think a little different about how you write your tests, at least it should. Nesting of describe also makes it possible to group your tests functionally, and the resulting report has a "readable" feeling to it.

从摩卡文档中引用该示例:

Quoting the example from the Mocha docs:

describe('Array', function(){
    describe('#indexOf()', function(){
        it('should return -1 when the value is not present', function(){
            assert.equal(-1, [1,2,3].indexOf(5));
            assert.equal(-1, [1,2,3].indexOf(0));
        })
    })
})

它显示为:

不存在该值时，Array#indexOf()应该返回-1

Array#indexOf() should return -1 when the value is not present

前两个描述仅设置(描述/分组)作用域，而it是运行的实际测试. #没有特殊含义.在这种情况下，它只会使输出文本/报告看起来更像API文档.

The first two describes just sets up the (descriptional/grouping) scope, and the it is the actual test that is run. # has no special meaning. In this case, it just makes the output text/report look a little more API-doc like.
