問題描述

如果滿足兩個期望之一，我需要將測試設置為成功:

I need to set the test to succeed if one of the two expectations is met:

expect(mySpy.mostRecentCall.args[0]).toEqual(jasmine.any(Number));
expect(mySpy.mostRecentCall.args[0]).toEqual(false);

我希望它看起來像這樣:

I expected it to look like this:

expect(mySpy.mostRecentCall.args[0]).toEqual(jasmine.any(Number)).or.toEqual(false);

我在文檔中遺漏了什么還是我必須編寫自己的匹配器?

Is there anything I missed in the docs or do I have to write my own matcher?

推薦答案

注意:此解決方案包含 Jasmine v2.0 之前版本的語法.有關自定義匹配器的更多信息，請參閱:https://jasmine.github.io/2.0/custom_matcher.html

Note: This solution contains syntax for versions prior to Jasmine v2.0. For more information on custom matchers now, see: https://jasmine.github.io/2.0/custom_matcher.html

Matchers.js 僅適用于單個結果修飾符" - not:

Matchers.js works with a single 'result modifier' only - not:

核心/Spec.js:

jasmine.Spec.prototype.expect = function(actual) {
  var positive = new (this.getMatchersClass_())(this.env, actual, this);
  positive.not = new (this.getMatchersClass_())(this.env, actual, this, true);
  return positive;

core/Matchers.js:

jasmine.Matchers = function(env, actual, spec, opt_isNot) {
  ...
  this.isNot = opt_isNot || false;
}
...
jasmine.Matchers.matcherFn_ = function(matcherName, matcherFunction) {
  return function() {
    ...
    if (this.isNot) {
      result = !result;
    }
  }
}

所以看起來您確實需要編寫自己的匹配器(從 before 或 it 塊中獲取正確的 this).例如:

So it looks like you indeed need to write your own matcher (from within a before or it bloc for correct this). For example:

this.addMatchers({
   toBeAnyOf: function(expecteds) {
      var result = false;
      for (var i = 0, l = expecteds.length; i < l; i++) {
        if (this.actual === expecteds[i]) {
          result = true;
          break;
        }
      }
      return result;
   }
});
