Jest describe each

Similar to jest test each, but for describe() blocks.

describe.each([
    {a: 1, b: 1},
    {a: 1, b: 2},
    {a: 2, b: 1},
])("math functions given $a and $b", ({a, b}) => {
    it("adds up correctly", () => {
        expect(lib.sum(a, b)).toBe(a + b);
    });

    it("subtracts correctly", () => {
        expect(lib.sub(a, b)).toBe(a - b);
    });
});
