Please make wait retry

[steinybot]

What would you like?

I would like wait to retry.

Why is this needed?

In my case I intercept every request and check if it is a graphQL request and if it is I pull out the mutation name and alias the request using that. Then in my tests I can, with no extra setup, wait for a particular mutation. What I also want to do is wait for certain mutations and then if that mutation contains a particular value I will proceed. For example we have an auto save feature on our forms which has a bunch of debouncing etc. This means that the number of requests that actually get sent are not relevant, I just need to wait until a particular mutation with the field I care about gets saved. In this specific test I am checking that I can resume from an autosaved state. If I don't wait then I can't tell if I am resuming before or after the autosave I am interested in occurred. If I had to wait for a certain number of requests to occur then the test would be overspecified and extremely brittle (if the number of requests is even deterministic). I'm going to have to duplicate my interception logic within each test and give it some other unique alias.

Other

wait automatically increments so retrying makes a lot of sense.

Alternatively I would like to be able to make any command retry even then via an option.

I managed to do it this way. Notice that I'm using cy.get instead of cy.wait.

cy.get('@interceptedRequest').its('request.body').should(body => {
    expect(JSON.stringify(body)).to.include('content');
});

I managed to do something similar by only waiting for the request I need:

    cy.intercept('GET', '/path/to/resource', req => {
      if (!ctx.id) return;
      req.alias = `alias-${ctx.id}`;
    });
    cy.wrap(ctx).then(() => {
      // Calling this in .then ensures id is set to what I need at this point.
      cy.wait(`@alias-${ctx.id}`)
        .its('response.body')
        .then($body => {
          expect($body).not.to.be.undefined;
        });
    });
