Usage

Export a default function that accepts a test suite.
To fail a test just throw, or use an assertion library.

import { TestSuite, TestParams } from "just-test-api";
import { expect } from "chai"; // Example of an assertion library.
import { MyClass } from "./MyClass"; // The class you want to test.

export default function(suite: TestSuite) {
    suite.describe("MyClass", (suite: TestSuite) => {
        suite.test("some test", () => {
            let myClass = new MyClass();

            let actual = myClass.foo();

            expect(actual).to.equal("hello");
        });

        suite.test("some test with stages", (t: TestParams) => {
            t.arrange();
            let myClass = new MyClass();

            t.act();
            let actual = myClass.foo();

            t.assert();
            expect(actual).to.equal("hello");
        });

        suite.test("async test", async (t: TestParams) => {
            let myClass = new MyClass();

            let actual = await myClass.foo();

            expect(actual).to.equal("hello");
        });

        suite.testFunc(when_adding_2_number_then_the_sum_is_correct);

        suite.testFunc(function inline_function_with_name(t: TestParams) {
            expect(1 + 2).to.equal(3);
        });

        suite.testFuncs(test1, test2);
    });
}

function when_adding_2_number_then_the_sum_is_correct(t: TestParams) {
    expect(1 + 2).to.equal(3);
}

function test1(t: TestParams) {}
function test2(t: TestParams) {}
