class RuboCop::Cop::RSpec::ImplicitExpect
Check that a consistent implicit expectation style is used.
This cop can be configured using the `EnforcedStyle` option and supports the `–auto-gen-config` flag.
@example `EnforcedStyle: is_expected`
# bad it { should be_truthy } # good it { is_expected.to be_truthy }
@example `EnforcedStyle: should`
# bad it { is_expected.to be_truthy } # good it { should be_truthy }
