有什么方法可以调用包含 it() 和运行的 Mocha 函数吗？

Question

我正在尝试像下面这样简单地调用 Mocha 函数

this.logSomething = function() {
    console.log('======== outside it ========')
    it('something inside it', function logSomething(done){
        console.log('+++++++ something inside it ++++++++') 
        done()  
    })
}

来自另一个 js 文件。使用 mocha.run(logSomething())

后

======== outside it ========

出现但

+++++++ something inside it ++++++++

丢失。

我试过使用'describe'，但结果是一样的。有没有绕过的解决方案？

仅供参考，我知道它可以运行通过将其导入为 Mocha 测试并使用 Mocha CLI，但是我想使用此方法重新运行我的测试套件中的失败函数，因此它可能是零个或多个具有不同名称的函数，并且它不像导入一定数量的 Mocha 测试那么简单。

此外，我已经尝试了 Mocha 现有的重试，但由于它不符合我们的测试，所以我没有使用它。

一个简单的例子

导出您的 logSomething 函数，将其导入另一个文件并执行它确实给了我您期望的行为：

lib.js

module.exports.logSomething = function() {
    console.log('======== outside it ========')
    it('something inside it', function logSomething(done){
        console.log('+++++++ something inside it ++++++++')
        done()
    })
}

test.js

const {logSomething} = require('./lib');
logSomething();
logSomething();

输出

$ mocha test.js
======== outside it ========
======== outside it ========


+++++++ something inside it ++++++++
  ✓ something inside it
+++++++ something inside it ++++++++
  ✓ something inside it

包含多个文件和 classes

的示例

所以这是一个更复杂的示例：有一个 test.js，它从两个单独的文件中导入两个 classes。每个 class 都有两种方法，依次使用 it().

运行 mocha 测试用例

test.js

const {TestSet1} = require('./lib1');
const {TestSet2} = require('./lib2');

new TestSet1().runTest1();
new TestSet1().runTest2();
new TestSet2().runTest1();
new TestSet2().runTest2();

lib1.js

class TestSet1 {

    runTest1() {
        it('should run TestSet1.Test1.It1', () => {
            console.log('This is output from TestSet1.Test1.It1');
        });
        it('should run TestSet1.Test1.It2', () => {
            console.log('This is output from TestSet1.Test1.It2');
        });
    }

    runTest2() {
        it('should run TestSet1.Test2.It1', () => {
            console.log('This is output from TestSet1.Test2.It1');
        });
        it('should run TestSet1.Test2.It2', () => {
            console.log('This is output from TestSet1.Test2.It2');
        });
    }

}

module.exports = {TestSet1};

lib2.js

class TestSet2 {

    runTest1() {
        it('should run TestSet2.Test1.It1', () => {
            console.log('This is output from TestSet2.Test1.It1');
        });
        it('should run TestSet2.Test1.It2', () => {
            console.log('This is output from TestSet2.Test1.It2');
        });
    }

    runTest2() {
        it('should run TestSet2.Test2.It1', () => {
            console.log('This is output from TestSet2.Test2.It1');
        });
        it('should run TestSet2.Test2.It2', () => {
            console.log('This is output from TestSet2.Test2.It2');
        });
    }

}

module.exports = {TestSet2};

输出

$ mocha test.js


This is output from TestSet1.Test1.It1
  ✓ should run TestSet1.Test1.It1
This is output from TestSet1.Test1.It2
  ✓ should run TestSet1.Test1.It2
This is output from TestSet1.Test2.It1
  ✓ should run TestSet1.Test2.It1
This is output from TestSet1.Test2.It2
  ✓ should run TestSet1.Test2.It2
This is output from TestSet2.Test1.It1
  ✓ should run TestSet2.Test1.It1
This is output from TestSet2.Test1.It2
  ✓ should run TestSet2.Test1.It2
This is output from TestSet2.Test2.It1
  ✓ should run TestSet2.Test2.It1
This is output from TestSet2.Test2.It2
  ✓ should run TestSet2.Test2.It2
