Install

npm install --global qunit-migrate

Usage

  qunit-migrate -h

  Usage: qunit-migrate [options] <file ...>

  QUnit Migrate: A tool to migrate your files to QUnit 2.0 API

  Options:

    -h, --help                output usage information
    -V, --version             output the version number
    -c, --config <path>       Config file for qunit-migrate
    -P, --parser <regex|ast>  Parser to be used for parsing, Default: ast
    -w, --write               Pass if parsed files should be overwritten. Default: false
    -p, --preset <string>     Preset rule for jscs config. Default: jquery
    -j, --no-jscs             Pass if jscs fix should not be applied. Default: true

  Globbing is supported in files

  Examples:

    $ qunit-migrate "./**/*.js" -w --preset "google" -c "config.json"
    $ # This will migrate all js files in subdirectories using google
    $ # preset and config as config.json

Information: AST parser is more robust than regex parser

Configuration

Various rules can be toggled through use of custom config which can be passed via -c option.

Config Rules

Example:

qunit-migrate tries to change old QUnit code to new QUnit specifications.

For e.g. following code will be converted as follows:

// Taken directly from jquery-globalize
// file1.js
define([
  "cldr",
  "src/core",
  "json!cldr-data/supplemental/likelySubtags.json",
  "cldr/event"
], function( Cldr, Globalize, likelySubtags ) {
Cldr.load( likelySubtags );
module( "Globalize.locale" );
ssyncTest( "should allow String locale", function() {
  stop();
  Globalize.locale( "en" );
  ok( Globalize.cldr instanceof Cldr );
  equal( Globalize.cldr.locale, "en" );
  start();
});
});

$ qunit-migrate "file1.js" -w

to

// Taken directly from jquery-globalize
// file1.js
define( [ 
  "qunit",
  "cldr",
  "src/core",
  "json!cldr-data/supplemental/likelySubtags.json",
  "cldr/event"
], function( QUnit, Cldr, Globalize, likelySubtags ) {
Cldr.load( likelySubtags );
QUnit.module( "Globalize.locale" );
QUnit.test( "should allow String locale", function( assert ) {
  var ready = assert.async();
  Globalize.locale( "en" );
  assert.ok( Globalize.cldr instanceof Cldr );
  assert.equal( Globalize.cldr.locale, "en" );
  ready();
});
});

API

$ npm install --save qunit-migrate

var qunitMigrate = require('qunit-migrate');
var qmAst = qunitMigrate.ast;
var qmRegex = qunitMigrate.regex;
var data = 'Some old qunit code';

var modifiedDataAST = qmAst(data); // Fixed code through AST
var modifiedDataRegex = qmRegex(data); // Fixed code through AST

Information: qunit-migrate api doesn't fix source with jscs

Accuracy & Limitations

QUnit migrate tries its best to upgrade your API, but there are still some limitations.

For e.g.

• If you are encapsulating some of your logic in a function and using assertions in that, it is your responsibility to pass assert into function parameters. API of qunit-migrate can also be upgraded to do this, but it doesn't support it at the moment
• There might be issues with require definitions some time if they are not in the start and encapsulated somewhere.
• QUnit.reset is not supported as of now

All these are fixable through AST. Pull requests are welcome
