    Replaced by karma-browserify

    karma-browserifast

    Browserify your JavaScript on the fly when testing with Karma.

    Installation

    Install with npm:

    npm install karma-browserifast

    Configuration

    tl;dr version:

    module.exports = function (karma) {
        karma.set({
            frameworks: ["browserify"],
     
            // Files that are to be loaded as globals
            files: [
                "node_modules/es5-shim/es5-shim.js"
            ],
     
            // Files to browserify
            browserify: {
                files: [
                    "test/**/*.js"
                ]
            },
     
            // Hopefully temporary hack
            preprocessors: {
                "/**/*.browserify": "browserify"
            }
     
            // ...
        });
    };

    Somewhat more elaborate version

    Add "browserify" to your list of frameworks in karma.conf, e.g.:

    frameworks: ["browserify"]

    Any tests or other files to browserify should not be listed in Karma's files configuration. Instead, use the browserify key. This accepts the same list as files, e.g. filenames as strings, and/or objects with pattern, served, included and watched properties.

    // Files that are to be loaded as globals
    files: [
        "node_modules/es5-shim/es5-shim.js"
    ],
     
    // Files to browserify
    browserify: {
        files: [
            "test/**/*.js",
            { pattern: "integration/**/*.js",
              watched: false }
        ]
    }

    The last step is a temporary hack that we hope to get rid of very soon:

    preprocessors: {
        "/**/*.browserify": "browserify"
    }

    What is this? karma-browserifast works by adding a file to Karma's list of files. This file resides in your OS tmp directory, and if you set the log level to karma.LOG_DEBUG, karma-browserifast will tell you the exact file name. This file is empty, and the above pre-processor provides the content Karma will use. This content is of course the browserified JavaScript.

    The reason for this somewhat elaborate approach is that Karma's framework hook does not wait for asynchronous operations, meaning we can't browserify in this hook. The pre-processors however, are asynchronous, thus this hack. We're investigating how to fix this weirdness.

    Optional configuration options

    browserify: {
        debug: true
    }

    Adds sourcemaps to your Browserify bundle.

    File watching

    When you move files from Karma's list of files to the browserify list, you also opt out of Karma's watching feature. Don't worry, karma-browserifast has your back. It tells Karma to watch its bundle, and updates this whenever your files change. The Karma autoWatch configuration option, as well as individual files configurations (e.g. watch: true|false), are respected. If autoWatch is true, dependencies resolved by browserify will be watched in addition to files explicitly enumerated.

    Alternatives

    There's also karma-browserify, however, we found its performance to be unacceptable as the number of files in our project increases. karma-browserify adds a pre-processor that browserifies all known files each time a new file is passed to it. This means that for n files, karma-browserify will run browserify n! times and write to the same file n times. This quickly becomes noticably slow.
