Create a nested structure to explicit the tests steps in AAA pattern

[marcopollivier]

Hi guys.

I'm starting to use Ava as my default testing framework, and a feature that I'm missing a lot is the possibility of separating my test steps (BDD-like).

I love to use AAA-pattern and define a specific and clear sentence for each step.

it helps a lot to design my tests and to find some errors during the development.

Is there a way to do it? If not, do you think makes sense to implement something like that?

A Jest example to illustrate it

describe('Given ...', () => {

//code

  describe('When...', () => {
    
//code

    it('Then ...', () => {

      expect().toEqual(
        expect.objectContaining(expected)
      )
    })
  })

That's not offered by AVA itself. There's https://www.npmjs.com/package/ava-describe which may still do what you want.

I've thought about ways to build custom test() functions which would lend itself to a BDD interface being built on top but I haven't the time.

I liked this lib but my concern is about the last update. 6y-ago 😱

I haven't checked, but that may not be a bad thing. The main AVA interface hasn't changed much.

Yes, I know, but the lib does not update the dependencies either. And in spite of this lib will be used only in the dev profile, out-of-dated-libs concerns me.
