Here you go:
干得好：
console.log(this.title);
回答by Louis
If you are directly inside a callback to describe, you can use this.titlefor the title of the describeor this.fullTitle()to get the hierarchical title of the describe(ancestors' titles + the title of this one). If you are inside a callback to ityou can use this.test.titleor this.test.fullTitle()respectively. So:
如果您直接在对 的回调中describe，则可以使用或this.title的标题来获取（祖先的标题+ 此标题的标题）的分层标题。如果您在回调中，则可以分别使用或。所以：describethis.fullTitle()describeitthis.test.titlethis.test.fullTitle()
describe("top", function() {
console.log(this.title);
console.log(this.fullTitle());
it("test", function () {
console.log(this.test.title);
console.log(this.test.fullTitle());
});
});
The console.logstatements above will output:
console.log上面的语句将输出：
top
top
test
top test
Here's a fuller example that shows how the titles change depending on nesting:
这是一个更完整的示例，显示标题如何根据嵌套而变化：
function dump () {
console.log("running: (fullTitle)", this.test.fullTitle(), "(title)",
this.test.title);
}
function directDump() {
console.log("running (direct): (fullTitle)", this.fullTitle(), "(title)",
this.title);
}
describe("top", function () {
directDump.call(this);
it("test 1", dump);
it("test 2", dump);
describe("level 1", function () {
directDump.call(this);
it("test 1", dump);
it("test 2", dump);
});
});
The console.logstatements will output:
该console.log语句将输出：
running (direct): (fullTitle) top (title) top
running (direct): (fullTitle) top level 1 (title) level 1
running: (fullTitle) top test 1 (title) test 1
running: (fullTitle) top test 2 (title) test 2
running: (fullTitle) top level 1 test 1 (title) test 1
running: (fullTitle) top level 1 test 2 (title) test 2
回答by Andrew Homeyer
From within a beforeEach, try this.currentTest.title.
从内beforeEach，尝试this.currentTest.title。
Example:
例子：
beforeEach(function(){
console.log(this.currentTest.title);
})
Using Mocha 3.4.1.
使用摩卡3.4.1。
回答by Ken
For mocha "^5.1.0" you can use console.log(this.ctx.test.title);
对于摩卡“^5.1.0”，您可以使用 console.log(this.ctx.test.title);
回答by Amado Saladino
Inside any test method
在任何测试方法中
it('test method name'), function() { var testName= this.test.title; }
and you may use :
你可以使用：
afterEach(function(){
console.log(this.currentTest.title); //displays test title for each test method
});
