暂停后，我继续测试我的 Rails 应用程序。现在在我的 rails 应用程序上运行测试会返回 SystemStackError。即使是一个简单的测试，如

def test_per_page

assert_instance_of Fixnum, Activity.per_page

结尾

在给我

我发现我们已经安装并删除了 test-unit gem。即使在那之后同样的问题不断出现。我在使用 rcov 的同时也安装了 rcov 和同样的东西..

以前有没有人遇到过这样的事情.. 我知道 gem 需要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。一个在 environment.rb 文件中，另一个在 config 文件夹的 env 子文件夹中的单独的 test.rb 文件中。所以它一直在不断地循环下去。无论如何问题都解决了，地球仍在旋转。

谢谢
