✿ Testosterone

Virile testing for http servers or any nodejs application.

Installation

npm install testosterone

WhateverDrivenDevelopment

Testosterone allows you to follow BDD or TDD on any of your projects using the same testing library.

Options

• host: Host to do the http calls. localhost
• port: Port to do the http calls. 80
• output: Configure the amount of verbosity you want for your tests
  • specs: Print the specs true
  • ticks: Print the ✓ and ✗ ticks true
  • summary: Prints the summary true
  • title: Prints the title true
• title: Test title, it will be printed out. Testosterone
• sync: If set to true, you don't need to call done to specify when your tests are done. false

API

testosterone API is simple and flexible.

• get|post|head|put|delete...(url, req, response, cb): Does a http call with the given request. If a response is given, testosterone will assert that the real response matches.
• add(spec, function(done)): Adds a test. The test is considered executed when done function is called.
• before(function): Runs before each test.
• after(function): Runs after each test.
• run([cb]): Runs the tests in serial. cb will be called once all the tests are executed.
• assert: You must use this assert object instead of the native one.

All the functions are chainable.

Show me the code

You have more examples on the test folder:

HTTP testing example:

var testosterone = require('testosterone')({port: 3000})
  , assert = testosterone.assert;

testosterone
  .get('/', function (res) {
    assert.equal(res.statusCode, 200)
  })

  .get('/hi', function (res) {
    assert.equal(res.statusCode, 500);
    assert.equal(res.body, 'use post instead');
  })

  .post('/hi', {data: {message: 'hola'}}, {
    status: 200
  , body: 'hola'
  });

// Output

$ node test.js

✿ Testosterone : ✓ ✓ ✓ ✓ ✓
» 3 responses, 5 asserts

Asynchronous example:

var testosterone = require('testosterone')({post: 3000, title: 'Testing async'})
  , assert = testosterone.assert;

testosterone

  .before(function () {
    console.log('test about to run!');
  })

  // using done to tell testosterone when the test is done
  .add('First test', function (done) {
    setTimeout(function () {
      assert.ok(true);
      done();
    }, 999);
  })

  // same but currying
  .add('Second test', function (spec) {
    assert.ok(true);

    setTimeout(done(function () {
      assert.ok(true);
    }), 10);
  })

  .run(function () {
    require('sys').print('All tests passed!');
  });

// Output

$ node test.js

✿ Testing async :

First test => ✓
Second test => ✓ ✓

» 0 responses, 3 asserts

Example with gently stubbing and sync: true:

var testosterone = require('testosterone')({post: 3000, title: 'Testing with stubs', sync: true})
  , gently = new (require('gently'))
  , fs = require('fs')
  , assert = testosterone.assert;

testosterone
  .add('GIVEN foo.txt \nWHEN its empty \nTHEN it return null', function (spec) {
    gently.expect(fs, 'readFile', function (path, encoding, cb) {
      assert.equal(path, 'foo.txt');
      cb(null, null);
    });

    fs.readFile('foo.txt', 'utf-8', function (er, data) {
      assert.equal(er, null);
      assert.equal(data, null);
    });
  })

  .add('GIVEN foo.txt \nWHEN it have content \nTHEN it return that content', function (spec) {
    gently.expect(fs, 'readFile', function (path, encoding, cb) {
      assert.equal(path, 'foo.txt');
      cb(null, 'foo');
    });

    fs.readFile('foo.txt', 'utf-8', function (er, data) {
      assert.equal(er, null);
      assert.equal(data, 'foo');
    });
  })

  .run(function () {
    require('sys').print('done!');
  });

// Output

$ node test.js

✿ Testing with stubs :

GIVEN foo.txt
WHEN its empty
THEN it return null => ✓ ✓ ✓

GIVEN foo.txt
WHEN it have content
THEN it return that content => ✓ ✓ ✓

» 6 asserts

Test

In order to run the tests type:
