• Allows you to write your test with Typescript decorator while using your favorite testing framework
• ... is a candy for the Java JUnit folks

• a framework, which does nothing for you but convert your functionally rich file into a more modular format

• [x] Modular test
• [ ] Decorators
  • [x] Test Class: @TestClass(desc?)
  • [x] Hooks: @BeforeAll, @BeforeEach, @AfterEach, @AfterAll
  • [ ] Test Suites: @Test(desc?, skip?, order?)
    • [x] Base decorator
    • [x] skip
    • [ ] Order (not really useful)
• [ ] Testing Platform impl
  • [x] Custom platform
  • [x] jest
  • [ ] vitest
  • [ ] Mocha
  • [ ] playwright
  • [ ] cypress
  • [ ] Jasmine

src/sum.ts

import {TestClass, Test} from "@yumii.saiko/testy";

export function sum(...numbers: number[]) {
  return numbers.reduce((acc, n) => acc + n, 0);
}

@TestClass({
  desc: "fn Sum()",
})
export class SumTest {
  @Test()
  should_compute_numbers_sum() {
    expect(sum(10, 10)).toEqual(20);
  }

  @Test({
    skip: true,
    desc: "Explicitly skip this for now",
  })
  not_implemented_yet() {}
}

Using the filename pattern that your testing framework might identify, example src/test/*/**/*.spec.ts, create a single file in which all of the Test class registrations should go.

src/test/bootstrap_test.spec.ts

import {defineTests} from "@yumii.saiko/testy";
// There we provided our own impl for jest platform
// Testy will come with a set of platform so you don't need to impl them yourself
import {PlatformJestImpl} from "../lib/testy_platform_jest";
import {SumTest} from "../sum";

defineTests([SumTest], PlatformJestImpl);

Run

npm test
