导轨奇怪的单元测试失败

本文介绍了导轨奇怪的单元测试失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我尝试运行这个最简单的单元测试：

I try to run this simplest unit test:

test "the truth" do assert true end

像这样：

ruby -Itest test/unit/my_model_test.rb

是文件中唯一的一个测试，实际上在整个站点）

(there is the only one test in the file, and actually in the whole site)

它失败了这个消息：

ActiveRecord::RecordNotUnique: SQLite3::ConstraintException: column email is not unique: INSERT INTO "users"... [some values to insert here]

现在我有一个名为users的表，但除了我以前从未要求过的任何测试，我甚至没有这样的测试。这个错误来自哪里？如何运行我的测试？

now I do have a table named "users" but other than that I have never asked to do any tests on it nor do I even have such tests. Where does this error come from? How do I run just my test?

编辑：users表来自设计宝石，如果这有帮助

the "users" table comes from the devise gem if that helps

推荐答案

从 guides.rubyonrails/ test.html

默认情况下，Rails将自动从您的设备的测试/夹具文件夹中加载所有夹具，功能测试。加载涉及三个步骤：

Rails by default automatically loads all fixtures from the test/fixtures folder for your unit and functional test. Loading involves three steps:

• 从与夹具相对应的表中删除任何现有数据
• 将夹具数据加载到表格中
• 将夹具数据转储到变量中，以防您要直接访问

所以我想你需要检查这些装置。另外我建议你阅读该教程。写得很好。

So I think you need to check those fixtures. Also I suggest you to read that tutorial. It is very well written.
