Used jests test.each for the first time. The syntax is kinda confusing but I grokked it in the end.
```
test.each([
  [1, 1, 2],
  [1, 2, 3],
  [2, 1, 3],
])(".add(%i, %i)", (a, b, expected) => {
  expect(a + b).toBe(expected);
});
```
The array of arrays passed is the variables and expected params for your test. The last item in the array is the expected value . You can have any number of values before which represent the aruguments or conditions of your text.
