How to loop through dynamic test cases with Jest and JavaScript?

To loop through dynamic test cases with Jest and JavaScript, we use the each method.

For instance, we write

test.each([
  [1, 1, 2],
  [1, 2, 3],
  [2, 1, 3],
])(".add(%i, %i)", (a, b, expected) => {
  expect(a + b).toBe(expected);
});

to call test.each with an array of arguments for the callback.

In the callback, we add the test code that uses the parameters.
