re-jest
Jest bindings in ReasonML
This is a set of bindings to jest in ReasonML, It aims to be simpler to use than bs-jest, with most functions returning unit, enabling a developer to write their tests with the same approach they would take writing them in JavaScript, but without needing to leave the type safety of ReasonML.
describe("myTests", () => {
test("numbers", () => {
let myNumber = 123;
expect(myNumber)->toBeGreaterThan(100);
expect(myNumber)->not->toBeLessThanOrEqual(1);
// It also works for floats...
expect(myNumber->float_of_int)->toBeLessThan(124.0);
});
testAsync("promises", () => {
expect(Js.Promise.resolve(123))->resolves->toEqual(123);
});
test("arrays", () => {
expect([|1, 2, 3, 4, 5|])->toContain(4);
});
// Still working on this one...
Skip.test("billion dollar idea generator",
() =>
expect(generateBillionDollarCompany()->valuation)
->toBeGreaterThan(1000000000)
);
});Stability
Very much a work in progress, but nonetheless it can do enough to test plenty of existing code.
