Unit testing error: Assertion 1 failed: call effects do not match (Even though the expected and actual result are the same)

Hi I’m having this weird issue, that when I’m passing the call action in an unit test I’m receiving this error, test was working before, but I add to that saga a CancelToken for cancelling the request.

    Expected
    --------
    { '@@redux-saga/IO': true,
      combinator: false,
      type: 'CALL',
      payload: 
       { context: null,
         fn: [Function: getVisualizations],
         args: [ '1', { token: [Object], cancel: [Function: cancel] } ] } }

    Actual
    ------
    { '@@redux-saga/IO': true,
      combinator: false,
      type: 'CALL',
      payload: 
       { context: null,
         fn: [Function: getVisualizations],
         args: [ '1', { token: [Object], cancel: [Function: cancel] } ] } }

As you can see, I believe they’re exactly the same outputs, but they don’t match. This is the failing test:

    describe("Unit testing", () => {
      let saga = testSaga(getVisualizationSaga, action);
      const cancel = CancelToken.source();
      it("fetches visualizations", () => {
        saga
          .next()
          .call(getVisualizations, action.payload, cancel)

          .next()
          .put(fetchVisualizationsSucceed())

          .next()
          .isDone();
      });
    });
  });

Hi! I’m having the same issue.

Seems there code that generates the output only goes so deep, probably standard toString or something.

There might be differences hiding for you underneath the token or cancel keys.

@bodazhao how did you expand the log here? I’ve tried --expand and --debug and other things.
