Rails 测试系统堆栈错误

Question

我在暂停后恢复测试我的 Rails 应用程序。在我的 Rails 应用程序上运行测试现在会返回 SystemStackError。 这样的简单测试也

即使像def test_per_page

assert_instance_of Fixnum, Activity.per_page

end

给了我

我发现我们安装了测试单元 gem 并删除了它。即使在那之后，同样的问题仍然不断出现。我安装了 rcov，在使用 rcov 时也做了同样的事情。

有没有人跑过之前遇到过类似的事情..我知道 gem require 被一遍又一遍地调用..有没有办法解决这个问题？

哎呀！当环境启动时，我有两个为 rcov 运行的初始化程序。一个位于environment.rb 文件中，另一个位于config 文件夹中env 子文件夹中的单独test.rb 文件中。所以它不断地循环下去。无论如何，问题解决了，地球仍然在旋转。

谢谢
