在Heroku上运行Rails单元测试 [英] Running Rails unit tests on Heroku

问题描述

我已经为Heroku部署了一个应用程序，并且一切正常。问题是我无法让我的单元测试远程运行。我试过了：

I've deployed an app to Heroku, and it all works fine. The problem is I can't get my unit tests running remotely. I've tried:

heroku rake test:units

和

and

heroku rake db:test:prepare

但是我得到一个巨大的堆栈跟踪，结尾是：

but for both I get a massive stack trace, ending with:

rake aborted!
undefined method `[]' for nil:NilClass
/app/[id]/home/.bundle/gems/ruby/1.9.1/gems/activerecord-3.0.3/lib/active_record/railties/databases.rake:429:in `block (3 levels) in <top (required)>'
/usr/ruby1.9.2/lib/ruby/1.9.1/rake.rb:634:in `call'
/usr/ruby1.9.2/lib/ruby/1.9.1/rake.rb:634:in `block in execute'
/usr/ruby1.9.2/lib/ruby/1.9.1/rake.rb:629:in `each'
/usr/ruby1.9.2/lib/ruby/1.9.1/rake.rb:629:in `execute'

我正在运行 bamboo-mri-1.9.2 堆栈。

到目前为止，我得到的答案最接近 2009年以来的这篇博客文章。

The closest I've got to an answer so far is this blog post from 2009.

推荐答案

Heroku不提供测试数据库，所以没有简单的方法来做到这一点。理论上讲，你可以创建一个新的heroku实例，并将rake任务破解为仅仅使用生产数据库，但我怀疑所需的努力是否值得。

Heroku doesn't provide a testing database, so there's no straightforward way to do that. You could theoretically create a new heroku instance and hack up the rake tasks to just use the 'production' database possibly, but I doubt the effort required would be worth it.
