JavaScript Leaders Demand Oracle Release the JavaScript Trademark
In an open letter, JavaScript community leaders urge Oracle to give up the JavaScript trademark, arguing that it has been effectively abandoned through nonuse.
jest-jasmine2
Advanced tools
The jest-jasmine2 package is a test runner for Jest that uses Jasmine 2 as its underlying test framework. It allows you to write and run tests using Jasmine's syntax and features within the Jest testing environment.
Basic Test Suite
This feature allows you to define a basic test suite using Jasmine's `describe` and `it` functions. The code sample demonstrates a simple test that always passes.
describe('Basic Test Suite', () => {
it('should pass a basic test', () => {
expect(true).toBe(true);
});
});
Setup and Teardown
This feature allows you to run setup and teardown code before and after each test using `beforeEach` and `afterEach` functions. The code sample demonstrates how to use these functions.
describe('Setup and Teardown', () => {
beforeEach(() => {
// Code to run before each test
});
afterEach(() => {
// Code to run after each test
});
it('should run setup and teardown', () => {
expect(true).toBe(true);
});
});
Matchers
This feature allows you to use various matchers to assert conditions in your tests. The code sample demonstrates the use of `toBe`, `toContain`, and `toEqual` matchers.
describe('Matchers', () => {
it('should use matchers', () => {
expect(1 + 1).toBe(2);
expect([1, 2, 3]).toContain(2);
expect({a: 1, b: 2}).toEqual({a: 1, b: 2});
});
});
Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple and fun. It provides a similar test structure with `describe` and `it` functions but does not include built-in matchers like Jasmine.
Chai is a BDD / TDD assertion library for Node.js and the browser that can be paired with any JavaScript testing framework. It provides a wide range of matchers and can be used with Mocha to achieve similar functionality to jest-jasmine2.
Jest is a delightful JavaScript Testing Framework with a focus on simplicity. It comes with its own test runner and assertion library, but it can also be configured to use Jasmine as the underlying test framework, similar to jest-jasmine2.
