重新运行第一个测试，如果第二个失败，摩卡，javascript

Question

I currently have

describeA();
describeB();

both A and B have it() tests. Is there a way to call describeA to run again, in describeB() after() function if any "it" fails in B? So in describeB after function it would have:

after(){

if(haveFailedTests)

// how to call run describeA();
}

You can override the it function of all your individual tests like so:

export function it(test: Function, retryCount: number = 4): (this: ITestCallbackContext, done: MochaDone) => any {
  return function() {
    for (let index = 0; index < retryCount; index++) {
      try {
        return test()
      } catch (error) {
        ;(browser as any).logger.info(
          `retry number ${index + 1}/${retryCount} for step "${error.message}" on it "${
            this.test.title
          }" and browser "${(browser.capabilities.browserName || '').toString()}"`
        )
      }
    }
    return test()
  }
}

This use typescript, but the basic idea remains, wrap your function call with a try/catch and rerun if it fails.
