poc-jest-sandbox

This is a sandbox repo for playing around with Jest + Typescript + Node.

Test that a function...

• gets called
• returns the expected results
• throws the expected errors

You might use describe like this

// describe noun
describe("The function", () => {
    // describe behavior
    describe("should throw an error", () => {
        // test case
        test("when dependency throws", () => {
            //
        });

        // test case
        test("when input is bad", () => {
            //
        });
    });
});
