Test being skipped. Don't know why

Ruby
1

I am learning Ruby from Zed A. Shaw’s Learn Ruby The Hard Way.

I have come to this exercise and I am kinda stuck here.

shakib@shakib-ubuntu:/media/shakib/projects/ex49$ rake test
/home/shakib/.rvm/rubies/ruby-2.2.3/bin/ruby -I"lib:tests"

“/home/shakib/.rvm/rubies/ruby-2.2.3/lib/ruby/2.2.0/rake/rake_test_loader.rb”
“tests/test_parse.rb”
Run options:

# Running tests:

[2/3] ParseTest#test_parse_verb = 0.00 s
1) Skipped:
ParseTest#test_parse_verb [stop]:
[["noun", "I"], ["verb", "go"], ["direction", "inside"]]

Finished tests in 0.005502s, 545.2443 tests/s, 908.7405

assertions/s.
3 tests, 5 assertions, 0 failures, 0 errors, 1 skips

ruby -v: ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]

So that’s the terminal that shows 1 test being skipped.
Can any of you pros direct me to the correct direction here.

What testing framework do you have? Since Ruby 2.2.3 testing frameworks
are not bundled, but are available as gems.
Do you have any of these gems?

  • test-unit
  • minitest

minitest gem is installed… test-unit isn’t.

If ‘minitest’ is installed I don’t even know why the entire test runs at
all :slight_smile:

If you’d install Ruby 2.2.3 from scratch (and not upgrading from earlier
versions) test-unit wouldn’t get installed so “require ‘test/unit’”
should fail.

BUT: you are calling methods from the test that doesn’t exist in
‘lexicon.rb’:

def test_peek()
word_list = [[‘noun’, ‘I’],[‘verb’, ‘go’],[‘direction’, ‘inside’]]
assert_equal(peek(word_list), ‘noun’)
end

The #peek method doesn’t exist (only #initialize, #scan and
#convert_number)

Rewrite the test: 1. to use minitest (minitest has different testing
paradigms, choose the one that resembles most to the test/unit
TestCase), 2. call the proper methods

=========
Hint: You are using nested method definition here:

def scan(input)
input = input.split
out = []

def convert_number(inp)
  begin
    Integer inp

Ruby has NO nested methods. Up until the point #scan is not invoked,
#convert_number won’t exist.

MUHAHAHA :slight_smile:

You defined you own ‘skip’ method, but this is also a special keyword to
the Unit testing gem, and it instructs the test to skip.

I renamed the method (and all of its invocations) to some neutral word
(‘skipm’), and the problem is solved.

Thanks a lot!!

Finally the test is working!!
Renamed the skip function in parse.rb to skipper and voila! :slight_smile:

A side note: give your class and method names something more
descriptive, do not be afraid of them being 20-30 characters long, like
“use_readable_variables”.

Thanks for your help.
I have attached the parse.rb file where I have declared the peek and
other methods.

And it seems like I have another gem installed named
“test-unit-minitest”
I forgot to notify that to you before because I was using 1.9.3.
When I switched to 2.2.3 I noticed this gem.

Thanks for the advice. Really appreciate it.

I’m just learning ruby from this book.
I will try to be more descriptive when declaring functions and variables
from now on.
