Highground is in Beta and can be used as a testing framework for your small, one-off or prototype projects. It is not yet recommended for full-scale applications. The author finds it to be their first choice for ES6 prototyping, and hope you do too.

Highground is a fast, easy way to test your ES6 applications. It is inspired by Mocha and Jest, but written for simplicity in ES6.

I used to use Mocha or Jest when testing my small or prototype projects, but was frustrated by their lack of simplicity and native support for ES6. I eventually just started writing my tests in ES6 files and running them myself.

Enter Highground - the missing link between testing frameworks like Mocha and the most basic of testing methodologies, which is just writing the assertion and hoping it doesn't throw an error [or, when it does throw an error, it indicates to you clearly what changed or went wrong.].

Highground.js is a simple testing library.

• Tiny code base which is easy to understand
• Written in ES6 for ES6
• Familiar syntax - based on standard describe, it syntax
• Native async / await support, no support for callbacks
• Supports tests in browser or Node with no configuration
• describe, it and other helpers are added to the scope with import statements like everything else, and are not magically inserted
• Custom reporters allow for more sophisticated feedback, if desired

Mocha and Jest are run from the command line. They use an algorithm to determine what files to run as tests and in what order. They inject methods into the scope like describe and it, in an opaque process, and the test files are not valid ES6 since the injected methods may or may not be available.

Highground is different -

• Highground was written to support async / await syntax from the very beginning, and it does
• Highground is not run from the command line: You write your tests in normal JavaScript files and then simply run those files using babel-node or webpack
• Highground does not use an algorithm to determine what files are tests: instead you import any tests you would like to run into a main test file, using normal ES6
• Highground does not support mocking, snapshot testing

Note: Jest and Mocha contain many great features that Highground does not. Only choose Highground if you are certain you do not want these features

If you have never used Jest or Mocha and thought that the way that methods are injected into the scope or outdated and not suitable for ES6, then you do not need Highground - Jest is a better choice.

If you've tried using Mocha or Jest with your ES6 project, only to realize that you need some arcane combination of babel, webpack, babel-jest, etc, as well as verbose and mysterious config file just to even get your tests working, then Highground is for you. It's written in ES6, and doesn't support ES5. Highground considers methods appearing in the scope of your application without being imported to be pure nonsense.

##Usage

npm install --save-dev highground

//index.spec.js
import { describe, it } from 'highground';
describe("A simulation inside a simulation", () => {
  let world = {
      world: {
          world: true
      }
  };
    
  it("Should be inside another simulation [Passing Test]", () => {
      if (!world.world.world) {
        throw new Error();      
      }
  });
    
  it("But inside that simulation should be another simulation [Failing Test]", () => {
      if (!world.world.world.world) {
        throw new Error();
      }
  });
}); 

babel-node index.spec.js

Defines a suite of tests. Skipped if no tests are defined within using it.

import { describe, it } from 'highground';
describe("A suite", () => {
    it("A test", () => {
        throw new Error("Welcome to the real world, Summer.");      
    });
}); 

Defines a suite of higher priority.

Defines a suite of lower priority (will usually be skipped.)

Defines a test. Test passes if no errors are thrown during its execution, otherwise it fails.

Defines a test of higher priority.

Defines a test of lower priority (will usually be skipped.)

import { describe, it } from 'highground';
describe("A suite", () => {
    xit("This test has priority -1 and is skipped", () => {});
    it("This test has priority 0 and is skipped, too.", () => {});
    fit("This test has priority 1, the highest priority, and is run", () => {
        throw new Error("There's a plasma shard in the Abadongo cluster...");
    });
    
    fit("This test has priority 1 as well, and it's also run", () => {
        throw new Error("... if I get it, I'll be awesome.");
    });
});
