How to run a single test method using Unit::Test?

I tried: ruby -I test test/unit/model_test.rb -n "the truth" Loaded suite test/unit/model_test Started Finished in 0.000297873 seconds. 0 tests, 0 assertions, 0 failures, 0 errors

The following test is in the model_test.rb file:   test "the truth" do     assert true   end

Changing the name of the test ("the truth") does not affect the output: apparently it is not finding the test. It does find the test file. Changing the file name throws an error.

How to run a single test method? (Not a single test file.)

Thanks!

No guarantees but try -n test_the_truth
