Rails/ruby test - error report without line numbers

Rails
1

Hi all,

I’m new to Rails and new to Rails testing. I have a few questions:

First, the most important question. How do I get line numbers to be
reported with my errors when testing. Here is what I get back on a
typical error:

josh@josh-laptop:~/d/test$ ruby unit/line_test.rb -n test_update
Loaded suite unit/line_test
Started
E
Finished in 0.066663 seconds.

  1. Error:
    test_update(LineTest):
    NameError: undefined local variable or method `sdf’ for
    #LineTest:0xb6e61304

1 tests, 0 assertions, 0 failures, 1 errors

It is tough to debug without a line number and filename. From the code
samples I’ve seen, people generally get back a more verbose error
report. How do I enable this?

The next question is a small one. What is the difference between:
-ruby unit/line_test.rb
-ruby test -I unit/line_test.rb
-ruby test unit/line_test.rb

I’d like to know the difference since I’m unable to use the command in
the Rails Testing guide (third one).

Thanks!

Josh

Probably by not using Test::Unit. :) It sucks. Try RSpec instead. Better API and much more readable error reports.

Best,

I suggest running from your app root. What happens if you do
ruby -I test test/unit/line_test.rb

The next question is a small one. What is the difference between:
-ruby unit/line_test.rb

That will only work if you run from the test folder, in fact I am
surprised it works at all as I don’t know how it finds the app
environment.

-ruby test -I unit/line_test.rb

That should be ‘-I test’ not ‘test -I’ . It tells it to Include the
folder test in the search path, so that require ‘test_helper’ at the
top of the test file finds test/test_helper.rb

-ruby test unit/line_test.rb

I don’t think this would ever work.
