Supertest should report custom error messages

At the moment when the status message does not match the expectations we get an error message like:

"expected 200 "OK", got 500 "Internal server error"

It would be helpful to display a server custom error message if any, as defined by:

res.send(500, { error: 'something blew up' });

would display:

"expected 200 "OK", got 500 "something blew up"

I’m feeling the same way. Its really non-descriptive to have the standard status code error. However this is a pretty simple work around when trying to the match status code:

request(app)
.get(path)
.expect(function (res) {
  var expectedCode = 302
  var result = res.statusCode + " " + JSON.stringify(res.text)
  var expected = expectedCode + " " + JSON.stringify(res.text)
  assert.equal(result, expected)
})

I think this should be a part of supertest. Fixing a bug in the code, where the test simply states the error was 500 Internal Server Error is difficult. And it’s extra frustrating if you know your code is actually returning a meaningful error message.

Others seem to feel the same way: https://github.com/frenchie4111/supertest/commit/850d5d893d313f4515a581c16cb173a74fd7b4f8 (supertest fork)
