Additional information

Results when use other package tools

When I run a jest test using npm, yarn, and pnpm, the test passes.

The code I’m trying

it.each`
  a    | b    | expected
  ${1} | ${2} | ${3}
  ${2} | ${2} | ${4}
`('$a and $b add up to $expected', ({ a, b, expected }) => {
  expect(sum(a, b)).toBe(expected);
});

Results in a different notation

If the ParameterizedTest is written with an array instead of using back quote, it passes.

it.each([
   [1, 2, 3],
   [2, 2, 4],
 ])('$a and $b add up to $expected', (a, b, expected) => {
   expect(sum(a, b)).toBe(expected);
});
