QUnit-TAP

A TAP Output Producer Plugin for QUnit

DESCRIPTION

QUnit-TAP is a simple plugin for QUnit to produce TAP output.

QUnit-TAP provides TAP output feature for ANY version of QUnit (But there are some exceptions. See TESTED ENVIRONMENTS section below). With QUnit-TAP you can run your QUnit test scripts on your terminal, use TAP Consumers like prove for test automation, pass test output to Jenkins, and so on.

QUnit-TAP runs under headless browsers like PhantomJS, command-line js environments (like SpiderMonkey or Rhino), and CommonJS environments like Node.js, and of cource, runs on your real browser too.

CHANGELOG

• (2016/06/20) Release 1.5.1: Supports QUnit 2.0.0 and above.
• (2014/12/10) Release 1.5.0: Now supports QUnit 1.15.0 and above. Drops support for too old QUnit versions (before-1.0.0).
• (2013/08/08) Release 1.4.0: Now QUnit-TAP exports single qunitTap function as module.exports. Therefore, require("qunit-tap") returns qunitTap function itself. Please fix your code if you are using Node.js (or any CommonJS env). Provide tap#unsubscribe method to unsubscribe specified logging events.
• (2013/01/10) Release 1.3.0: Deprecate noPlan option: Now QUnit-TAP works as with noPlan: true by default. If you want to delare plan explicitly, please use QUnit.config.requireExpects option instead. Stop using QUnit.tap as namespace: qunitTap function now returns an object that represents QUnit-TAP API and customization subject.
• (2012/09/13) Release 1.2.0: Reorganize configuration options. Some options are marked as deprecated (with safe fallbacks). Changed output message format a little.

CAUTION for Node.js users

• BC BREAK: Since 1.4.0, QUnit-TAP exports single qunitTap function as module.exports. Therefore, require("qunit-tap") returns qunitTap function itself. Please fix your code if you are using qunit-tap module via npm.

TESTED ENVIRONMENTS

DOWNLOAD

• Just download qunit-tap.js
• or download archives from qunit-tap tags
• or git clone git://github.com/twada/qunit-tap.git
• or npm install qunit-tap if you use npm.
• or bower install qunit-tap if you use bower.

You can use QUnit-TAP,

• as a single file, copy lib/qunit-tap.js to anywhere you like.
• as git submodule.
• as a node.js package (via npm).
• as a bower component (via bower).

USAGE

Simple steps to use QUnit-TAP.

1. load/require qunit.js
2. load/require qunit-tap.js
3. Call qunitTap function with two or three arguments. The first argument is QUnit object reference, the second is print-like function for TAP output. And the third argument is object to customize default behavior. (Note that the first and second argument is mandatory, and the third argument is optional.)
4. (optional) qunitTap function returns an object that represents QUnit-TAP API.

usage example 1 : embed QUnit-TAP in your HTML (e.g. to run with PhantomJS)

<script type="text/javascript" src="path/to/qunit.js"></script>
<script type="text/javascript" src="path/to/qunit-tap.js"></script>
<script>
  qunitTap(QUnit, function() { console.log.apply(console, arguments); });
</script>
<script type="text/javascript" src="path/to/your_test.js"></script>
<script type="text/javascript" src="path/to/your_test2.js"></script>

usage example 2 : use QUnit-TAP with Node.js

First, declare qunitjs and qunit-tap as devDependencies in your package.json, then run npm install.

{
    . . .
    "devDependencies": {
        "qunitjs": "2.3.0",
        "qunit-tap": "1.5.1",
        . . .
    },
    . . .
}

Next, require and configure them.

var QUnit = require('qunitjs');
var qunitTap = require('qunit-tap');
qunitTap(QUnit, function() { console.log.apply(console, arguments); });
QUnit.config.autorun = false;

// your tests

QUnit.load();

usage example 3 : use QUnit-TAP with Rhino/SpiderMonkey

load("path/to/qunit.js");
load("path/to/qunit-tap.js");

// enable TAP output
qunitTap(QUnit, print);  //NOTE: 'print' is Rhino/SpiderMonkey's built-in function

// or customize default behavior
// qunitTap(QUnit, print, {showExpectationOnFailure: true, showSourceOnFailure: false});

// configure QUnit to run under non-browser env.
QUnit.config.autorun = false;

load("path/to/your_test.js");
load("path/to/your_test2.js");

QUnit.load();

CONFIGURATION OPTIONS

QUnit-TAP is already configured with reasonable default. To customize, qunitTap function takes third optional argument as options object to override default behavior. Customization props are,

• initialCount : Initial number for TAP plan line. Default is 1.
• showExpectationOnFailure : If true, show 'expected' and 'actual' on failure. Default is true.
• showTestNameOnFailure : If true, show test name on failure (supported since QUnit 1.10.0). Default is true.
• showModuleNameOnFailure : If true, show module name on failure (supported since QUnit 1.10.0). Default is true.
• showSourceOnFailure : If true, show source file name and line number on failure if stack trace is available. Default is true.

Related config option on QUnit

• QUnit.config.requireExpects : If true, QUnit-TAP prints expected assertion count as plan line at the bottom after all the test points have run. Otherwise, QUnit-TAP prints actual assertion count as plan line at the bottom after all the test points have run.

More on customization

You can even override moduleStart, testStart, log, done, testDone method in object returned from qunitTap function. In these methods, this refers to the object returned from qunitTap function.

var tap = qunitTap(QUnit, function() { console.log.apply(console, arguments); });
. . .
tap.moduleStart = function(arg) {
    // 'this' refers to tap object
    this.note('customized: ' + arg.name);
};

TAP OUTPUT EXAMPLE

QUnit-TAP produces output based on TAP specification.

# module: math module
# test: add
ok 1
ok 2
ok 3 - passing 3 args
ok 4 - just one arg
ok 5 - no args
not ok 6 - expected: 7, got: 1, test: add, module: math module
not ok 7 - with message, expected: 7, got: 1, test: add, module: math module
ok 8
ok 9 - with message
not ok 10 - test: add, module: math module
not ok 11 - with message, test: add, module: math module
# module: incr module
# test: increment
ok 12
ok 13
# module: TAP spec compliance
# test: Diagnostic lines
ok 14 - with\r
# multiline
# message
not ok 15 - with\r
# multiline
# message, expected: "foo\r
# bar", got: "foo
# bar", test: Diagnostic lines, module: TAP spec compliance
not ok 16 - with\r
# multiline
# message, expected: "foo
# bar", got: "foo\r
# bar", test: Diagnostic lines, module: TAP spec compliance
1..16

Configuration for this example is,

qunitTap(QUnit, function() { console.log.apply(console, arguments); }, {
  showSourceOnFailure: false
});

Explicitly, it's same as,

qunitTap(QUnit, function() { console.log.apply(console, arguments); }, {
  initialCount: 1,
  showExpectationOnFailure: true,
  showTestNameOnFailure: true,
  showModuleNameOnFailure: true,
  showSourceOnFailure: false
});

RUNNING EXAMPLES

prepare

$ git clone git://github.com/twada/qunit-tap.git
$ cd qunit-tap

to run with PhantomJS

# with prove
$ prove --exec=sh phantomjs_test.sh

for details, see phantomjs_test.sh

for details, see sample/commonjs/

TROUBLE SHOOTING

qunitjs loading problem on Node

If you are using Node.js (or any CommonJS env) and have an error like this,

$ node test/incr_test.js 

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
Error: should pass QUnit object reference. Please check QUnit's "require" path if you are using Node.js (or any CommonJS env).
    at qunitTap (/path/to/qunit-tap.js:22:15)
    at Object.<anonymous> (/path/to/using_qunit_via_require_module.js)
    ....
$

Check QUnit's version you are using. QUnit's module export path has changed since QUnit 1.3.0, so you should fix 'require' path to get QUnit Object from 'require' module.

  var util = require("util"),
-     QUnit = require('./path/to/qunit').QUnit,
+     QUnit = require('./path/to/qunit'),
      qunitTap = require('qunit-tap').qunitTap;
  qunitTap(QUnit, util.puts);
  QUnit.config.autorun = false;

Official QUnit npm module is available since QUnit version 1.9.0, so the best way to get QUnit Object is just use 'qunitjs' module.

  var util = require("util"),
-     QUnit = require('./path/to/qunit').QUnit,
+     QUnit = require('qunitjs'),
      qunitTap = require('qunit-tap').qunitTap;
  qunitTap(QUnit, util.puts);
  QUnit.config.autorun = false;

for details, see my fix.

qunit-tap loading problem on Node

Similarly, QUnit-TAP exports single qunitTap function as module.exports since 1.4.0. Therefore, require("qunit-tap") returns qunitTap function itself. Please fix your code if you are using Node.js (or any CommonJS env).
