JEC Tiger Project

Tiger is the standard implementation of the JavaScript Unit Testing API (JUTA) specification. It provides the portability of unit tests for TypeScript applications.

JUTA allows developers to write portable unit tests, independently from the unit testing framework they use. Test suites are written in TypeScript and are based on the same kind of annotations than Junit.

The Tiger framework will run JUTA test suites over the Mocha framework.

Requirements

JEC Tiger needs the following system parameters in order to work correctly:

• Node 6+
• npm 3+
• TypeScript 2+

Installation

Set up the JEC Tiger and the Mocha modules with:

$ npm install jec-tiger --save-dev
$ npm install mocha --save-dev

Tiger Framework Initialization

You have to configure the Tiger framework with a basic script file (e.g. test-config.ts) in order to run JUTA unit tests:

import {TestStats} from "jec-juta";
import {Tiger, TigerFactory} from "jec-tiger";
 
const factory:TigerFactory = new TigerFactory();
const tiger:Tiger = factory.create();
tiger.process((stats:TestStats)=> {
  if(stats.error) console.error(stats.error);
 });

By default, test classes are located in the test folder, at the root of your project. You can use the Tiger API to set the location of the test folder:

const testFolder:string[] = ["my-test-folder"];
const tiger:Tiger = factory.create();
tiger.setTestPaths(testFolder);

To call the configuration file with the mocha command, add the following snippet to your package.json file:

...
"scripts": {
  "test": "mocha test-config"
}
...

Now, unit tests can be run by using the standard npm command:

$ npm test

Using JUTA Decorators

All JUTA decorators have to be imported with the ES6 syntax:

import { TestSuite, Test } from "jec-juta";
 
@TestSuite({
  description: "Tests the \"HelloWorld\" class methods."
})
export class HelloWorldTest {
  
  @Test(
    description: "should say Hello to the world 3 times",
    repeat: 3
  )
  public sayHelloTest():void {
    // Test here...
  }
}

For a complete list of available decorators, please refer to the JUTA project.

Running Tests

To execute all unit tests, use:

$ grunt test

API Reference

The API Reference documentation is not included into the JEC Tiger node module. To build the API reference documentation, use:

$ grunt doc

Documentation will be generated in the docs/api-reference repository. The online version of the API reference documentation will be available soon at the JEC Website.

The documentation generator is TypeDoc
