How can I test the connection refused case?

[LonelyGriffin]

I would like to write something like that:

await server.run()
await pactum.spec().get(healthUrl).expectStatus(200).expectBody('OK')

await server.shutdown()
await pactum.spec().get(healthUrl).expectConnectionRefused()

But I have not found a similar to expectConnectionRefused method. So I try to write something like that:

await server.run()
await pactum.spec().get(healthUrl).expectStatus(200).expectBody('OK')

await server.shutdown()
await pactum
  .spec()
  .get(healthUrl)
  .expect(({res}) => {
    expect(res.code).toBe('ECONNREFUSED')
  })

The problem with this way is the logger. I get the error log. Like this:

I can suppress this error, but I think it is better to have a native method for this case, or is there already a better solution?

Welcome to PactumJS Discussions & Thanks a lot for using this library.

This is an interesting use case. PactumJS doesn't have a native method to support error expectations. I too agree that we should have one.

As you mentioned having a method like expectConnectionRefused would solve this issue but it is explicit. We will discuss further and consider adding this method.

Instead, I will add a method something like expectError that would be generic for broader use cases.

// expect any error
await pactum.spec().get(healthUrl).expectError();

// expect ECONNREFUSED error
await pactum.spec().get(healthUrl).expectError('ECONNREFUSED');

// expect error object
await pactum.spec().get(healthUrl).expectError({ code: 'ECONNREFUSED' });

And once again thank you for your valuable suggestion.

@LonelyGriffin - expectError method is published as part of 3.0.12 version.
