Jest: [Discussion] Test Macros

[jacobp100]

In Ava, extraneous arguments you pass to it are passed to the function.

const testMacro = (input, expectedValue) => {
  const actualValue = parse(input);
  expect(actualValue).toEqual(expectedValue);
};

test('title', testMacro, 'input', 'expected');

Would something like this be useful for Jest? I know I would use it a lot.

The current behaviour is that the third argument is used as a timeout for async tasks. Changing this would be a breaking change.

Not exactly the same, but you can use similar syntax:

test('title', testMacro.bind(this, 'input', 'expected'));

Yeah we cannot break this right now. We are considering to adopt other test libraries instead of Jasmine and Ava's API is awesome, so I'd love to have a standalone version of that. I'm going to close this issue out for now as we aren't likely to build this.
