【问题描述】：
我想要一些关于如何测试我的一个 Django 表单中的错误的帮助或建议。它负责确保用户输入有效的会话 ID，该 ID 用作 3rd 方 API 的身份验证令牌。有效 ID 长度为 32 个字符，由字母数字组成。
我选择了一种验证字段的方法，而不是模型。
当我使用开发服务器手动测试它时，它按预期工作。 IE。如果用户粘贴长度错误的字符串或带有特殊字符的字符串，则该字段的 validate 方法会创建错误，然后通过 for 循环在 html 模板中的表单错误周围显示。
我不明白以下错误。我临时修改了 testcases.py 以证明错误正在传递给它 - 那么为什么 context[form].errors 是一个“属性”以及它是如何到达那里的？
我正在使用 Django 1.10 和 Python 3.5.1
