Overview
An adapter for the builtin Deno, Bun, and NodeJs testing frameworks which is useful for library authors that are targeting multiple JavaScript runtimes.
The librar provides a standard subset to run tests against all 3 runtimes rather than implement all features and test styles until node:test is available in all three testing runtimes.
Documentation
Documentation is available on jsr.io
Usage
psuedo code to show off the test function.
import { test } from "@bearz/testing";
test("simple", () => {
console.log("test");
});
test("use done", (_, done) => {
done(); // finishes the test.
done(new Error()); // finishes the test and throws an error.
});
test("async", async () => {
await Deno.writeTextFile("test.txt", test);
await exists("test.txt");
});
test("skip", { skip: true }, () => {
console.log("skipped test");
});
test("timeout", { timeout: 2000 }, () => {
// the test timeout will be exceeded
setTimeout(() => {}, 3000);
});Functions
test- defines a test
Notes
This library was written to deal with the frustration of targeting multiple JavaScript runtimes.
Vitest was failing to work with deno outside of very limited context. Vitest is cool, but it is/was heavy on the dependencies and it was failing run on Deno outside of a very limited context.
