Karma Esquire

A simple plugin to load the Esquire library and (optionally) a number of scripts before running Karma.

Installation

Install with NPM:

npm install --save-dev karma-esquire

Then just add the esquire module to your listed frameworks in karma.conf.js.

module.exports = function(config) {

  config.set({
    // ...
    frameworks: ['esquire', /* ... */ ],
    files: [
      // ...
    ]
};

Loading scripts

When working with Karma for unit testing, the Esquire.karma(...) method can be used to specify what scripts to be loaded with each run.

The Esquire.karma(...) method takes either a RegExp or a callback function:

This method can be invoked multiple times, and all callbacks or expressions will be evaluated. If any of them matches, the script will be loaded.

Regular Expressions

When invoked with a RegExp, any file matching the expression will be loaded.

// This will load all '/tests/deferred/....js' files
Esquire.karma(/^\/tests\/deferred\/.\.js$/);

Callback functions

When invoked with a callback function, the callback will be invoked once for every file known to Karma and if the callback returns a truthy value, said file will be loaded as a script dependency.

// The callback function will be invoked for every file, and said
// file will be loaded if the function returns a truthy value
Esquire.karma(function(file) {
 return ...;
});
