我正在尝试在javascript中学习测试驱动开发方面实现打印钻石的功能.

Diamond.prototype.outerSpace = function (current, widest) {

  var currentValue = this.getIndexOf(current);
  var widestValue = this.getIndexOf(widest);

  if (currentValue > widestValue) {
      throw new Error('Invalid combination of arguments');
  }

  var spaces = widestValue - currentValue;
  return new Array(spaces + 1).join(' ');
};

我在错误处理方面遇到问题.如果currentValue大于widestValue,则上述函数应抛出错误.

这是我的代表测试/规范的片段:

it ("should throw an exception, if it is called with D and C", function () {
    var outerSpace = diamond.outerSpace.bind(diamond, 'D', 'C');
    expect(outerSpace).toThrow('Invalid combination of arguments');
});

我也试过在expect(..)中使用匿名函数,但这也没有用.

控制台消息是:预期函数抛出'Inval ...'但它抛出错误:参数组合无效.

我不明白,我应该怎么做这些信息.

编辑:这很奇怪,因为它与Jasmine v.1.3一起使用,但它与jasmine v.2.3 ie或与业力无关,尽管代码基于茉莉.

如上所述,我将尝试在注册过程中使用某个额外规则来验证密码.如果密码至少有一个数字,一个字母和一个特殊字符,则额外规则应该是密码验证.

我解决这个问题的方法我创建了一个名为validators.py的文件.

from django.core.exceptions import ValidationError

class CustomPasswortValidator:

    def validate(value):

      # check for digit
      if not any(char.isdigit() for char in value):
          raise ValidationError(_('Password must contain at least 1 digit.'))

      # check for letter
      if not any(char.isalpha() for char in value):
          raise ValidationError(_('Password must contain at least 1 letter.'))

      # check for special character
      special_characters = "[~\!@#\$%\^&\*\(\)_\+{}\":;'\[\]]"
      if not any(char in special_characters for char in value):
        raise ValidationError(_('Password must contain at least 1 letter.'))

我的自定义注册表单如下所示:

from django import forms
from django.contrib.auth.forms …
