Skipping tests with describe.only or describe.skip is running the code inside

[carlesba]

When I skip tests (either with .only or .skip) the code inside the skipped tests seems to still be running but the expectations are omitted. This is particularly bothering when using console.logs inside the tested code since you don't know which case is running.

example:

const add = (a, b) => {
  console.log('add');
  return a+b;
}
describe("add", ()=>{
  describe("positive numbers", () =>{
    it("adds 2+2", ()=> {
      expect(add(2,2)).toBe(4);
    })
  })
  
  describe.only("negative numbers", () => {
    it("adds (-2) + (-2)", () => {
      expect(add(-2,-2)).toBe(-4);
    })
  })
})

In this case we'll see 2 logs. I would expect that the skipped tests don't run at all so we can only see one log.

Is it correct to see 2 logs? In that case, how do you debug your code when a test is failing?
