Jasmine/量角器:在 beforeEach 中停止失败测试 [英] Jasmine/Protractor: stop test on failure in beforeEach

问题描述

我目前正在编写测试量角器，我想知道是否有可能在 beforeEach 中的某些内容失败时立即取消测试执行(并返回一些有用的消息，例如前提条件失败:无法登录用户").IE.我在 beforeEach 中有一些帮助方法，用于登录用户然后进行一些设置.

I am currently writing tests protractor and I was wondering if there is some possibility to cancel test execution as soon as something in the beforeEach fails (and return some useful message like "precondition failed: could not login user"). I.e. I have some helper methods in the beforeEach that login the user and then do some setup.

beforeEach:
  1) login user
  2) set some user properties

如果第一个步骤失败，显然执行第二个步骤没有任何意义(实际上它非常有害，因为用户被锁定，这不好).我尝试在第一步中添加一个期望"，但第二步仍然执行 -> 新的想法.

Obviously it does not make any sense to execute the 2nd step if the first one fails (actually its quite harmful as the user gets locked which is not nice). I tried to add an "expect" as part of the 1st step, but the 2nd step was still executed -> fresh out of ideas.

推荐答案

jasmine.Env.prototype.bailFast = function() {
  var env = this;
  env.afterEach(function() {
    if (!this.results().passed()) {
      env.specFilter = function(spec) {
        return false;
      };
    }
  });
};

然后只需调用:

jasmine.getEnv().bailFast();

(感谢 hurrymaplelad，他编写了一个可以做到这一点的 npm，但是你不需要使用它)

(credit goes to hurrymaplelad who wrote an npm that does just that, however you don't need to use it)
