If you've used Capybara and RSpec, you've probably used matchers like:
With CapybaraMiniTestSpec you can have similar functionality while using MiniTest::Spec:
You can also use the TestUnit style assertions:
assert_page_has_content page, 'Title'
But if you really want to be simple with MiniTest::Unit, you don't need this gem. You can do the following without this gem:
assert page.has_content?('Title'), 'Your custom failure message'
However, if you choose to use this gem, you get Capybara's failure messages as if you were using RSpec matchers.
assert_page_has_content?('<h1>Content</h1>', 'No such Text') # fails with 'expected there to be text "No such Text" in "Content"'
You can see all the available matchers here. CapybaraMiniTestSpec iterates through those "have_x" methods and creates corresponding MiniTest assertions/expectations.
# Gemfile gem 'capybara_minitest_spec'
NOTE: If after installing the Capybara gem, Nokogiri isn't installed, it's a known bug (https://github.com/jnicklas/capybara/issues/882).
If you choose to use Rails's default ActionDispatch::IntegrationTest, just extend Minitest::Spec::DSL. E.g.
# Maybe in a helper or something. ActionDispatch::IntegrationTest.extend Minitest::Spec::DSL
Otherwise you may see this exception:
NoMethodError: undefined method 'assert_page_has_content' for nil:NilClass.
In theory, this should work with Capybara >= 2. The latest version it was tested with was Capybara 2.4.1.
For Capybara < 2 support, use a version of this gem < 1.0.
Supports Minitest >= 4. It may work for earlier versions, I just haven't tested it. If you need it to support an earlier version, let me know and I'll see what I can do.
Cucumber is not officially supported. See #10 for a possible workaround.
This gem was tested by basically copying the Capybara spec located in 'spec/rspec/matchers_spec.rb' and altering the test to run with MiniTest.
