How do you parameterize a test over several inputs?

for (const email of ["", "bad", "a@"]) {
  test(`rejects "${email}"`, async ({ page }) => {
    // ...
  });
}

1Pass an array as the second argument to test()
2Loop and declare a test with a unique title for each
3Use test.each, the only supported approach

Show the answer

Correct answer: Loop and declare a test with a unique title for each

Explanation

Playwright collects tests by running the file, so a loop creates one test per value. Titles must be unique.
