BUG -- Concurrency error with node-http adapter when running a test suite with skipped test

[AELSchauer]

Description

Running a test suite with any skipped tests with jest (xit, it.only, it.skip) results in a concurrency error. However, running the same set of tests in which no tests are skipped, does not result in any errors.

it('test A', async () => {

});

xit('test B', async () => {
  ...
});

Error Message & Stack Trace

Config

Copy the config used to setup the Polly instance:

setupPolly({
  adapters: [NodeHttpAdapter],
  persister: FSPersister,
  persisterOptions: {
    fs: {
      recordingsDir: path.resolve(__dirname, '__recordings__')
    }
  }
});

Dependencies

Copy the @pollyjs dependencies from package.json:

{
    "@pollyjs/adapter-node-http": "^5.0.0",
    "@pollyjs/core": "^5.0.0",
    "@pollyjs/persister-fs": "^5.0.0",
    "jest": "^26.4.2",
    "jest-circus": "^26.4.2",
    "setup-polly-jest": "^0.9.1",
}

Thanks for all the info, we'll look into it.

@gribnoysup I wonder if this is an issue caused by the jasmine setup done in setup-polly-jest? Have you run into this sort of issue before?

[gribnoysup]

Hmmm... we have a test case for it.only and I just added one for it.skip and both are passing on jest with jasmine2 and with circus runner. It might be something with the setup-polly-jest helper especially as jest-circus support is pretty new and I don't think a lot of people are using it, but it would be really hard to tell without a reproduction. Maybe you can provide a more complete example @AELSchauer?
