angular2-testing-lite

angular2-testing-lite

Jasmine-free Angular 2 Testing Library

Features

• Jasmine-free
• Same core API as angular2/testing
• Less API: supports only TestInjector and TestComponentBuilder
• Opt-in utilities for Mocha

Install

$ npm install --save-dev angular2-testing-lite

Usage (Mocha & power-assert example)

Model

Simple mocha test

import assert = require("power-assert");

describe("TestModel", () => {

    it("can instantiate", () => {
        let model = new TestModel("AAA");
        assert(!!model);
    });

    describe("toString()", () => {
        it("should return string", () => {
            const model = new TestModel("AAA");
            const str = model.toString();
            assert(typeof str === "string");
        });
    });
});

Service

Inject Http

import assert = require("power-assert");
import {async, inject} from "angular2-testing-lite/core";
import {it, describe, xdescribe, beforeEach, beforeEachProviders} from "angular2-testing-lite/mocha";

describe("TestService", () => {

    beforeEachProviders(() => [
        BaseRequestOptions,
        MockBackend,
        provide(Http, {
            useFactory: (backend: MockBackend, options: BaseRequestOptions) => {
                return new Http(backend, options);
            }, deps: [MockBackend, BaseRequestOptions]
        }),
        TestService
    ]);

    it("can instantiate", inject([TestService], (service: TestService) => {
        assert(!!service);
    }));
});

Component

Ported TestComponentBuilder

import assert = require("power-assert");
import {inject, async, TestComponentBuilder} from "angular2-testing-lite/core";
import {describe, it, xit, beforeEachProviders, beforeEach} from "angular2-testing-lite/mocha";
import {HTTP_PROVIDERS} from "@angular/http";

describe("TestAppComponent", () => {

    beforeEachProviders(() => [
        HTTP_PROVIDERS,
        TestService,
    ]);

    it("can create", async(inject([TestComponentBuilder],
        (tcb: TestComponentBuilder) => {
            return tcb.createAsync(TestAppComponent)
                .then(fixture => {
                    assert(!!fixture);
                });
        })
    ));
});
