Hello Marcelo,

Any comments on the failing tests on CI?

It would be nice to take a look at those.

For instance, please, take a look at the following error (which seems to be related to your changes):

When I click the Back link # features/step_definitions/user_steps.rb:1

  Unable to find link "Back" (Capybara::ElementNotFound)

  ./features/step_definitions/user_steps.rb:2:in `/^I click the (.+) link$/'

  features/repository/show/independent.feature:36:in `When I click the Back link'

Whenever you propose a patch, make sure you change the tests accordingly

Hi Athos,

When we ran the tests locally, they really passed. But in trevis build some related with our changes had broken.

We fixed those related with our changes, but trevis were still breaking with some timeout tests. So we had open another pull request that increase the time of these timeouts too.

The new pull request is #404.

Can we close this in favour of #404?
