class RuboCop::Cop::RSpec::ContainExactly
Checks where ‘contain_exactly` is used.
This cop checks for the following:
-
Prefer ‘match_array` when matching array values.
-
Prefer ‘be_empty` when using `contain_exactly` with no arguments.
@example
# bad it { is_expected.to contain_exactly(*array1, *array2) } # good it { is_expected.to match_array(array1 + array2) } # good it { is_expected.to contain_exactly(content, *array) }
Constants
- MSG
- RESTRICT_ON_SEND
