How to reproduce Rails unit tests in the Rails console (error about routes)












0














I'm an experienced programmer, but brand new to Ruby and Rails. I want to try building new tests for an existing project, so I thought a good way to start would be to reproduce existing tests line by line in the Rails console. However, I haven't been able to make it work.



As this question suggests, I went to the main directory of the project and did this:



$ rails console -e test

Loading test environment (Rails 5.2.0)

irb(main):001:0> require './test/test_helper'

[Coveralls] Set up the SimpleCov formatter.

[Coveralls] Using SimpleCov's 'rails' settings.

   (1.0ms)  SELECT "schema_migrations"."version" FROM "schema_migrations" ORDER BY "schema_migrations"."version" ASC

=> true


So far so good. But I still couldn't load the actual test modules:



irb(main):002:0> require './test/controllers/users_controller_test'

Traceback (most recent call last):

        2: from (irb):2

        1: from test/controllers/users_controller_test.rb:1:in `<top (required)>'

LoadError (cannot load such file -- test_helper)


So then I tried adjusting the $LOAD_PATH as follows, which seems to work:



irb(main):003:0> $LOAD_PATH.unshift '/{{absolute path to project}}/test'

{{irb now prints the new $LOAD_PATH which is really long}}

irb(main):004:0> require './test/controllers/users_controller_test'                         

=> true


But when I try to run the actual tests, it's still not working. It looks like some kind of unloaded "routes":



irb(main):008:0> my_test = UsersControllerTest.new("My Test")

=> #<UsersControllerTest:0x000055c90aadd148 @NAME="My Test", @failures=, @assertions=0>

irb(main):009:0> my_test.test_routes

Traceback (most recent call last):

        2: from (irb):9

        1: from test/controllers/users_controller_test.rb:11:in `test_routes'

NoMethodError (undefined method `recognize_path' for nil:NilClass)

irb(main):010:0> my_test.test_new_view

Traceback (most recent call last):

        2: from (irb):10

        1: from test/controllers/users_controller_test.rb:191:in `test_new_view'

RuntimeError (@routes is nil: make sure you set it in your test's setup method.)


Is there an easier way to run tests from the console? How can I resolve the missing "routes" so I can run the tests from the rails console? Or is my goal inadvisable to begin with?

    I would say it's a non standard approach. If I were to do this, I would write an empty test and put only binding.pry inside (pry is a popular debugger). By running the single test and hitting the breakpoint you would be sure that everything is initialized properly and you could start tinkering in the console.

  • @MarcinKołodziej that sounds great! So I did gem install pry and confirmed that require 'pry' works in irb. Then I added require 'pry' at the top of the test .rb file and binding.pry in the middle and ran the file with rails test. But I get a many-lines error ending with "cannot load such file -- pry (LoadError)" Any idea why?

  • Try adding gem "pry" to your Gemfile, running bundle install and bundle exec rails test.

    @MarcinKołodziej it works! I did gem install pry, added gem "pry" to the project's Gemfile, added require 'pry' at the top of the test .rb file and binding.pry in the middle. Still can't run most of the tests for various reasons, but pry is a good starting point for now.

Run scheduled task as local user group (not BUILTIN)
