Execute the tests with:
$ ruby hamming_test.rb
Only the first test will be executed, all the others have been made pending
skip method. Delete or comment the next
skip as you get
each test passing.
skip method instructs the test suite to not run a test. This is commonly used to avoid running tests of unimplemented functionality, so you can focus on the part you are currently working on.
The test run summary will list the number of skipped tests. You should disable all of the skips before completing an exercise.
Customizing Test Reporting
If you want color, execute the tests with:
$ ruby hamming_test.rb -p
If you want to see the test names, execute the tests with:
$ ruby hamming_tests.rb -v
If you would like to run only one test, you can specify one or a group with regular expression style matching.
$ ruby hamming_tests.rb -n /empty/
You can combine the options as well.
Disabling All The Skips
With your new found powers of being able to select the individual or groups of tests that you want to run, you may want to disable all the skips.
The Quick and Dirty
Taking advantage of the fact that in Ruby methods are overridable, if you were to add this line of code;
def skip ; end
like this in the Hamming test file
class HammingTest < Minitest::Test def skip ; end def test_identical_strands
then all the skips will still evaluate, yet will let your tests run.
The Still Quick And Cleaner
Of course, editing all the files through time can be irritating, so you could do like we did in developing the exercises... make a file that has the skip definition in it, and require that as a library when we want it.
We created a
lib folder to keep our "helper" things in, and it looks
require 'minitest/autorun' # You can use this to disabe all skips in the current exercise by issuing the # following command: # ruby -I../lib -rdisable_skip <filename_test.rb> module Minitest class Test def skip(_msg='', _bt=caller) end end end
The description on how to use it is commented in that file listing, and the file listing is in its complete state.
