How can I test it with multiple parameters with using test.each?

Hi, first of all, thank you for this great code base. I'm appreciating it every day.

I have a trouble using it with parametric tests.

I have a code like this:

  it("with some ids as parameters ", async () => {
    await testApiHandler({
      handler: usersListHandler,
      test: async ({ fetch }) => {
        test.each`
          id          | expected
          ${"someID1}     | ${200}
          ${"someID2"} | ${200}
        `(`parameter loop`, async ({ id, exStatus }) => {
          const response = await fetch({
            body: JSON.stringify({id})
          })
          const status = response.status
          expect(status).toBe(200)
        })
      },
    })
  })

which fails because of the following error:

    Tests cannot be nested. Test "parameter loop" cannot run because it is nested within "with some ids as parameters".

      273 |           id          | expected
      274 |           ${"someID1}     | ${200}
    > 275 |           ${"someID2"} | ${200}
          |                              ^
      276 |         `(`with some ids as parameters`, async ({ id, expected }) => {
      278 |

What I would like to do is tesiting next-api with multiple parameters.

Of course, I can solve it with using promise array and resolve it with Promise.all but this does not have great visibility in jest result. Any workaround for this? Thanks!

Sorry... I solved it with myself.

it.each`
id | expected
"someID1" | 200
"someID2" | 200
`("with some ids as parameters. id: $id, expected: $expected", async () => {
    await testApiHandler({
      handler: usersListHandler,
      test: async ({ fetch }) => {
          const response = await fetch({
            body: JSON.stringify({id})
          })
          const status = response.status
          expect(status).toBe(200)
        }
      },
    })
  })

Thanks!

I was just about to suggest moving the test.each outside of the testApiHandler function. Glad you got it working!
