RSpec matching response

I am using Ruby on Rails 5 and Rspec.

My test is like

expect(json_response['data']['body']).to match(/'["can't be blank"]'/)

I am getting error

expected ["can't be blank"] to match /'["can't be blank"]'/

I was wondering, how to fix it ? Hope it is clear.

Reading the test failure, the JSON response returns an array with a string in it: ["can't be blank"]. Seems like a fine use case for testing equality directly:

expect(json_response['data']['body']).to eq(["can't be blank"])

match_array will work, but it "disregards differences in the ordering between the actual and expected array." As an array with one item only, that feature isn't necessary here.

Try the match_array helper method.

expect(json_response['data']['body']).to match_array(["can't be blank"])
