How to output names of ruby unit tests

Question

I have a unit test (example is modified Test::Unit documentation)

require 'test/unit'

class TC_MyTest < Test::Unit::TestCase
  def test_something
    assert(true)
  end
end

When I execute it, I get:

Loaded suite C:/test
Started
.
Finished in 0.0 seconds.

1 tests, 1 assertions, 0 failures, 0 errors

I would like to get something like this (test_something is outputted):

Loaded suite C:/test
Started
test_something
.
Finished in 0.0 seconds.

1 tests, 1 assertions, 0 failures, 0 errors

Answer 1

Run unit test with verbose option.

test.rb -v v

or

test.rb --verbose=verbose

Output:

Loaded suite C:/test
Started
test_something(TC_MyTest): .

Finished in 0.0 seconds.

1 tests, 1 assertions, 0 failures, 0 errors

Answer 2

Command line options do not work if you are creating your own test runner:

Test::Unit::UI::Console::TestRunner.run(TC_MyTest)

You will have to specify verbosity in test runner. Test::Unit::UI options are:

SILENT = 0, PROGRESS_ONLY = 1, NORMAL = 2, VERBOSE = 3.

So, for verbose:

Test::Unit::UI::Console::TestRunner.run(TC_MyTest, 3)

Answer 3

If you're testing in rails you can use

rake test TESTOPTS=-v
