Test parameter vs multiple regexp n RSpec

I have a method which handle failure on some api calls. I wrote tests for it:

  it 'logs the error' do
    expect(Rails.logger).to receive(:error).with(/Failed API call/i)
    expect(Rails.logger).to receive(:error).with(/#{error_type}/)
    expect(Rails.logger).to receive(:error).with(/#{server_error}/)
    subject
  end

but to make it work I would need to make 3 api calls or split it to 3 test cases. I don't like both of the solutions. I think the best one would be to combine 3 regexp into single expectation.

Is it possible to put multiple Regexps on single parameter in one test case?

You could combine all these regexp into one (using regexp's AND operator).

  let(:expected_log_message) do
    /(?=.*Failed API call)(?=.*#{error_type})(?=.*#{server_error})/i
  end

this regexp will test string if it matches all of above.

Then inside a test case:

  it 'logs the error' do
    expect(Rails.logger).to receive(:error).with(expected_log_message)
    subject
  end
