Question

我正在尝试创建一个带有逻辑的afterEach挂钩，该挂钩只应在前一次测试失败时触发。例如：

it("some_test1", function(){
  // something that could fail
})

it("some_test2", function(){
  // something that could fail
})

afterEach(function(){
  if (some_test_failed) {
    // do something to respond to the failing test
  } else {
    // do nothing and continue to next test
  }
})

但是，我没有办法在afterEach挂钩中检测测试是否失败。是否有某种事件监听器我可以附加到摩卡？也许是这样的：

myTests.on("error", function(){ /* ... */ })

Answer 1

您可以使用this.currentTest.state（不确定何时引入）：

afterEach(function() {
  if (this.currentTest.state === 'failed') {
    // ...
  }
});

Answer 2

您可以执行以下操作

describe('something', function(){
  var ok = true;
  it('should one', function(){
    ok = true;
  })

  it('should two', function(){
    // say the test fails here
    ok = false;
  })

  afterEach(function(){
    if (!ok) this.test.error(new Error('something went wrong'));
  })
})

从Mocha中的afterEach挂钩中检测测试失败
