Capybara/CurrentPathExpectation

Yes

Yes

1.18

2.0

Checks that no expectations are set on Capybara’s current_path.

The have_current_path matcher should be used on page to set expectations on Capybara’s current path, since it uses Capybara’s waiting functionality which ensures that preceding actions (like click_link) have completed.

This cop does not support autocorrection in some cases.

Examples

# bad
expect(current_path).to eq('/callback')
expect(page.current_path).to eq('/callback')

# good
expect(page).to have_current_path('/callback', ignore_query: true)

# bad (does not support autocorrection when `match` with a variable)
expect(page).to match(variable)

Capybara/VisibilityMatcher

2.0

Checks for boolean visibility in Capybara finders.

Capybara lets you find elements that match a certain visibility using the :visible option. :visible accepts both boolean and symbols as values, however using booleans can have unwanted effects. visible: false does not find just invisible elements, but both visible and invisible elements. For expressiveness and clarity, use one of the symbol values, :all, :hidden or :visible. Read more in the documentation.

Examples

# bad
expect(page).to have_selector('.foo', visible: false)
expect(page).to have_css('.foo', visible: true)
expect(page).to have_link('my link', visible: false)

# good
expect(page).to have_selector('.foo', visible: :visible)
expect(page).to have_css('.foo', visible: :all)
expect(page).to have_link('my link', visible: :hidden)
