Use have_css or have_xpath instead of have_selector.

Examples

# bad
expect(foo).to have_selector(:css, 'bar')

# good
expect(foo).to have_css('bar')

# bad
expect(foo).to have_selector(:xpath, 'bar')

# good
expect(foo).to have_xpath('bar')

DefaultSelector: css (default)

# bad
expect(foo).to have_selector('bar')

# good
expect(foo).to have_css('bar')

DefaultSelector: xpath

# bad
expect(foo).to have_selector('bar')

# good
expect(foo).to have_xpath('bar')

Prefer using predicate matcher over using predicate method directly.

Capybara defines magic matchers for predicate methods. This cop recommends to use the predicate matcher instead of using predicate method directly.

Examples

Strict: true, EnforcedStyle: inflected (default)

# bad
expect(foo.matches_css?(bar: 'baz')).to be_truthy
expect(foo.matches_selector?(bar: 'baz')).to be_truthy
expect(foo.matches_style?(bar: 'baz')).to be_truthy
expect(foo.matches_xpath?(bar: 'baz')).to be_truthy

# good
expect(foo).to match_css(bar: 'baz')
expect(foo).to match_selector(bar: 'baz')
expect(foo).to match_style(bar: 'baz')
expect(foo).to match_xpath(bar: 'baz')

# also good - It checks "true" strictly.
expect(foo.matches_style?(bar: 'baz')).to be(true)

Strict: false, EnforcedStyle: inflected

# bad
expect(foo.matches_style?(bar: 'baz')).to be_truthy
expect(foo.matches_style?(bar: 'baz')).to be(true)

# good
expect(foo).to match_style(bar: 'baz')

Strict: true, EnforcedStyle: explicit

# bad
expect(foo).to match_style(bar: 'baz')

# good - the above code is rewritten to it by this cop
expect(foo.matches_style?(bar: 'baz')).to be(true)

Strict: false, EnforcedStyle: explicit

# bad
expect(foo).to match_style(bar: 'baz')

# good - the above code is rewritten to it by this cop
expect(foo.matches_style?(bar: 'baz')).to be_truthy
