mini-mocha

An absolutely minimal emulation of Mocha for demos.

Why

This was hacked together very quickly for demo purposes, making it possible to verify bugs on the Sinon issue tracker without having access to a development environment. Having an API emulation of Mocha makes it easier to demo bugs on RunKit when I see a verification test using Mocha or Jasmine, as I can just copy-paste the test into RunKit, add require('@fatso83/mini-mocha').install() at the top and it will run!

Typical usage

require('@fatso83/mini-mocha').install();

describe("issue #101 ES5 version", function() {
    it("shows a normal sync test", function() {
        // passes
    });

    it("will fail", function() {
        throw new Error("My error");
    });

    it("shows a normal async test using callbacks", function(done) {
        setTimeout(() => {
            done();
        });
    });

    it("will fail async", function(done) {
        setTimeout(() => {
            done(new Error("My error"));
        });
    });
});

Results in this being printed

$ node demo.js

issue #101 ES5 version
✔️  shows a normal sync test
❌ will fail (Failed with: "My error")
✔️  shows a normal async test using callbacks
❌ will fail async (Failed with: "My error")

async/await (aka Promises) feature
✔️  should pass as expected
❌ should fail (Failed with: "Some wrong type")

Known limitations

There are bits and pieces missing from the Mocha API, but it fulfills all the basic requirements.

• No support for Mocha internals like this.title, this.fullTitle(), etc.

Pull requests welcome :)

If you want to contribute, here are some tips:

• npm run update-snapshots will update the snapshots used for testing the output
