Does the 'matchesRegexp' in the Artillery's expect plugin only support GET requests?

[sprakshith]

Hello all,

I’m trying to use the matchesRegexp expectation in the Artillery expect plugin to validate the body of a POST API response.

At first, I thought my regex was the issue, but after debugging the plugin itself, I saw that the body passed into the function below is null for POST requests. It works fine for GET requests, though.

Is this expected behavior? Or am I missing something in how the plugin should be used with POST calls?

function expectMatchesRegexp(expectation, body[--> IS NULL FOR POST requests], req, res, userContext) {
  debug('check valid regexp');
  const expectationName = 'matchesRegexp';
  const expectedRegexp = template(expectation[expectationName], userContext);

  let rx;
  let result;
  try {
    rx = new RegExp(expectedRegexp);
    const matches = new RegExp(rx).test(body);
    result = {
      ok: matches,
      expected: true,
      type: 'matchesRegexp',
      got: matches
    };
  } catch (rxErr) {
    result = {
      ok: false,
      expected: true,
      type: 'matchesRegexp',
      got: rxErr
    };
  }
}
