intellij karma runner doesn't use watchify for bundle rebuild

[pchudzik]

When running karma tests from intellij autoWatch flag is always overwritten to false - https://github.com/JetBrains/intellij-plugins/blob/master/js-karma/src/js_reporter/karma-intellij/lib/intellij.conf.js#L56 (https://youtrack.jetbrains.com/issue/WEB-14437)

For small projects it doesn't really matter but in case project is big then bundling all js files can tak up to 20-30 seconds (with all the sources, and external dependencies).

karma-browserify depends on autoWatch = true which will trigger watchify. Now since idea always overwrite autoWatch to false then it's impossible to use watchify when running tests from idea. It means that every time I want to run tests I need to wait 20+ seconds for browserify to bundle from scratch :(

I've created ugly workaround for this - https://github.com/pchudzik/karma-browserify/commit/10ee655d8bf489cc2ff315815847e67410f0af3b With this bundle is built with watchiy in less than 1s. I can create proper PR with test and documentation but the question is will you accept this ugly workaround dedicated for intellij? It's basically the same as in https://github.com/nikku/karma-browserify/pull/24 but It wasn't merge because of https://youtrack.jetbrains.com/issue/WEB-12496 for which there is a workaround: In file ~/.IntelliJIdea2016.3/config/plugins/js-karma/js_reporter/karma-intellij/lib/intellijRunner.js find function runTests and change runWithConfig invocation param refresh to true. It should look like this:

function runTests() {
  var serverPort = cli.getServerPort();
  var urlRoot = cli.getUrlRoot() || '/';
  if (urlRoot.charAt(urlRoot.length - 1) !== '/') {
    urlRoot = urlRoot + '/';
  }
  runWithConfig({
    port: serverPort,
    refresh: true,
    urlRoot: urlRoot
  });
}

[bendrucker]

I don't think it's appropriate for this project to add and document hacks for a specific IDE

[nikku]

Glad you created that issue and good to know there exists an actual workaround.

We won't include that hack into our project, for the reasons @bendrucker outlined.

Others interested in a workaround may resort to your hack.

[pchudzik]

It's hack for one particular IDE (maybe more than one because there is intellij, webstorm, phpstorm, etc) and I'm not surprised that you decided to decline it :)

In case anybody stumbles on this I've decided to fix it and publish to npm (it's more convenient for me to use package from npm instead of github link): http://npmjs.com/package/karma-browserify-intellij https://github.com/pchudzik/karma-browserify

I will try to keep my fork up to date, and maybe one day jet brains will fix it...
