RSpec: use `receive ... exactly ... with ... and_return ...` with different `with` arguments

Question

I'm writing an expectation which checks whether a method is called two times with different arguments and returns different values. At the moment I'm just writing the expectation twice:

expect(ctx[:helpers]).to receive(:sanitize_strip).with(
  %{String\n<a href="http://localhost:3000/">description</a> <br/>and newline\n<br>},
  length: nil
).and_return('String description and newline')

expect(ctx[:helpers]).to receive(:sanitize_strip).with(
  %{String\n<a href="http://localhost:3000/">description</a> <br/>and newline\n<br>},
  length: 15
).and_return('String descr...')

I wonder if I can use receive ... exactly ... with ... and_return ... instead; something like:

expect(ctx[:helpers]).to receive(:sanitize_strip).exactly(2).times.with(
  %{String\n<a href="http://localhost:3000/">description</a> <br/>and newline\n<br>},
  length: nil
).with(
  %{String\n<a href="http://localhost:3000/">description</a> <br/>and newline\n<br>},
  length: 15
).and_return('String descr...', 'String description and newline')

The code above doesn't work, it raises the following error:

1) Types::Collection fields succeeds
   Failure/Error: context[:helpers].sanitize_strip(text, length: truncate_at)

     #<Double :helpers> received :sanitize_strip with unexpected arguments
       expected: ("String\n<a href=\"http://localhost:3000/\">description</a> <br/>and newline\n<br>", {:length=>15})
            got: ("String\n<a href=\"http://localhost:3000/\">description</a> <br/>and newline\n<br>", {:length=>nil})

Is there a way to use receive ... exactly ... with ... and_return ... with different with arguments?

Answer 1

There's an rspec-any_of gem that allows for the following syntax by prodiding all_of argument matcher:

expect(ctx[:helpers]).to receive(:sanitize_strip).with(
  %{String\n<a href="http://localhost:3000/">description</a> <br/>and newline\n<br>}
  all_of({length: 15}, {length: nil})
)
.and_return('String descr...', 'String description and newline')
.twice
