Testing Gems

[Caleb Tennis]

According to http://docs.rubygems.org/read/chapter/20#test_files, the
test_files section of the gemspec file lists test files that are loaded "when
the user requests a gem to be unit tested".

Is there a gem command to run the tests? I can't see one listed in the help,
but I may just be missing it.

Try something like:

$ gem install --test somegem

There is detail with:

$ gem help install
$ gem help examples

If the tests succeed, there's no output (at least by default?) but they do
run if they're there (after Rdoc I think).

Hi,

I recently had exactly the same question... So, maybe the Gemspec
Reference should be updated.

The install command has the --test or -t option.
Have a look at gem help install.

So, for example:
gem install examplegem --test

Interesting thing about running the tests this way ...
If the gem has no tests, it outputs "There are no unit tests to run".
If any tests fail, it prompts whether to keep the gem.
If no tests fail, there is no output and no indication that tests were run.

I don't really like that last part. I wish there was some output
indicating that the tests were actually run.
