Rails test hanging - how can I print the test name before execution?

Question

I'm having a test hang in our rails app can't figure out which one (since it hangs and doesn't get to the failure report). I found this blog post http://bmorearty.wordpress.com/2008/06/18/find-tests-more-easily-in-your-testlog/ which adds a setup hook to print the test name but when I try to do the same thing it gives me an error saying wrong number of arguments for setup (1 for 0). Any help at all would be appreciated.

Answer 1

If you run test using rake it will work:

rake test:units TESTOPTS="-v" 

Answer 2

The printing of the test name is the responsibility of the TestRunner. If you are running your tests from the command line you can specify the -v option, to print out the test case names.

example:

ruby test_Foo.rb -v
Loaded suite test_Foo
Started
test_blah(TestFoo): .
test_blee(TestFoo): .

Finished in 0.007 seconds.

2 tests, 15 assertions, 0 failures, 0 errors

Answer 3

This is what I use, in test_helper.rb

class Test::Unit::TestCase
  # ...

  def setup_with_naming 
    unless @@named[self.class.name]
      puts "\n#{self.class.name} "
      @@named[self.class.name] = true
    end
    setup_without_naming
  end
  alias_method_chain :setup, :naming unless defined? @@aliased
  @@aliased = true  
end

The @@aliased variable keeps it from being re-aliased when you run it on multiple files at once; @@named keeps the name from being displayed before every test (just before the first to run).
