this.timeout fails inside describe block about karma-parallel

[joeljeske]

Thank you for this bug report. This is occurring because this framework must call all the describe blocks in every instance, even those that contain it()s that will only be run in another instance. It is difficult and error-prone to fake the entire executing API of this for each describe.

As opposed to mocking the API, it might be easiest to put the this.timeout() in a before() or beforeAll(). Those will only be called in the instances that will actually run each test spec.

Example:

Instead of

describe('some_module/some_component', function() {
  this.timeout(10000);

  // Setup and run some tests
  ...
});

Try this

describe('some_module/some_component', function() {
  before(function() { // Runs once
    this.timeout(10000);
  });

  // Setup and run some tests
  ...
});

This approach works! I think if this is the only non-standard thing we have to do that I can get onboard with this approach.

I'm hesitant to deviate too much from following the mocha docs, but this exception alone would be worth it.

Coming across another issue that I'll open a separate ticket for.

For me, this is accessible and set timeout works in the before statement but it's reset in the it statement. As a workaround,

describe("component", () => {
  it("description", function(done) {
    this.timeout(10000); // place the timeout here make it works as expected.
    ...
  });
});

FYI, the code was as follow

describe("component", () => {
  it("description", (done) => {
    ...
  }).timeout(10000); // was set timeout here.
});
