Rails 'rake test' runs test twice immediately after creating new rails project

Question

Can someone offer troubleshooting tips here?:

With the following sequence of rails related commands:

rails new test6  
bundle install  
rails generate Controller Gohere left right up down
rake test

... seems to run the rake task 'test' twice. Where have I gone wrong?

log is here:

Answer 1

I realize this post is pretty old, but in case you never figured it out, or someone else is confused by this (like I was tonight), here's what's going on:

There are actually 2 sets of tests running here: functional tests & unit tests. When you generate a controller in a fresh Rails project like that, you get some functional tests, and you get a stubbed out unit test file with no actual tests in it.

So, the first test results line you see:

0 tests, 0 assertions, 0 failures, 0 errors, 0 skips

are the results for the empty unit test file.

As soon as you fill in some unit tests it will show you non-zero results. Note you can also run rake test:units or rake test:functionals to run just one set of tests.

I wish that there was some clearer output to indicate what's going on. It is confusing.
