黄瓜在场景结束之前执行挂钩之后

Question

I have an After hook in hooks.rb that deletes users created in the last scenario. I started to notice that when tests run at a specific time of the day , this hook is being executed in the middle of a scenario . There is a method that executes until a certain line and then the hook executes just before an assert command in that method, which fails because of it. The tests are run from a batch file ("ruby file_name.rb").

Does anyone have an idea why this might happen or how to solve it?

Thanks!

Answer 1

Don't you run your tests from command line like following?

$ cucumber

I would suggest to use debugger gem. You could add debugger statement just before you think is failing and then use some debugger commands

Perhaps related to: https://github.com/cucumber/cucumber/issues/52

Issue 52 is mostly fixed on the master, but I think there are a few remaining tests broken that need to be fixed before release.

Regardless of that, you might instead try using the database_cleaner gem for this purpose in general. We use a clean database before every scenario for testing to ensure we have discrete tests that cannot have false positive/negative results due to results of other tests. We use the following:

begin
  # start off entire run with with a full truncation
  DatabaseCleaner.clean_with :truncation
  # continue with the :transaction strategy to be faster while running tests.
  DatabaseCleaner.strategy = :transaction
rescue NameError
  raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
end

And we load our test seeds before each run: Before do |scenario| load Rails.root.join('db/seeds.rb') end

Note that our seeds.rb checks which environment it is running in to keep it short. A big seeds file run in this manner would significantly increase test run times, so be careful.
