如何在rake TestTask失败后抑制巨大的堆栈跟踪？

Question

我正在为一个项目设置一个rakefile,我已经定义了一些rake TestTasks.我运行了一个简单的健全性测试,assert_equal(1, 2)只是为了检查输出,除了通常的故障输出之外,我得到了这个烂摊子:

rake aborted!

/usr/bin/rake:31:in `<main>'

我怎么摆脱它？我不想向上滚动超过20行的垃圾来查看我的测试失败.

在这种情况下，Rake 不应该返回回溯——错误在于外部命令，而不是 rake 的内部。我已向 Jim Weirich 发送了有关以下补丁的电子邮件：https ://gist.github.com/1003628
