How about some integration with harnesses?

[undsoft]

More and more I find myself mixing harnesses and spectator.

Spectator is great for setting up dependencies and reducing Testbed boilerplate, while harnesses are great at abstracting away the logic behind UI elements.

For example, if you have a date picker component, you can hide its implementation details so that your tests look like this:

const birthday = await loader.getHarness(MyDatePickerHarness.with({ label: 'When were you born?' });
await birthday.pickDate('1989-09-18');

It's not this is impossible to do this utility functions and spectator, but it's just cleaner with harnesses.

So maybe spectator could have something to make it easier to work with harnesses? For example instead of doing:

let loader: HarnessLoader;

beforeEach(() => {
  // create component
  loader = TestbedHarnessEnvironment.loader(spectator.fixture);
});

it('allows user to specify birthday', async () => {
  const birthday = await loader.getHarness(MyDatePickerHarness.with({ label: 'When were you born?' });
  await birthday.pickDate('1989-09-18');
});

we could have spectator.loader be automatically available:

beforeEach(() => {
  // create component
});

it('allows user to specify birthday', async () => {
  const birthday = await spectator.loader.getHarness(MyDatePickerHarness.with({ label: 'When were you born?' });
  await birthday.pickDate('1989-09-18');
});

or just have getHarness right there.
