/**
* Executes Karma test from {@literal src/test/javascript}. It requires a Karma configuration file as:

* config.set({
* basePath: '${basedir}',
* frameworks: ['jasmine'],
* files: [
* '${project.build.outputDirectory}/assets/square.js',
* 'src/test/javascript/*.js'

* reporters:['progress', 'junit'],
* junitReporter: {
* outputFile: 'target/surefire-reports/karma-test-results.xml',
* suite: ''
* }
* });
* };}
*
* It is recommended to use {@literal target/classes/assets/*} as sources instead of {@literal
* src/main/resources/assets}, so file are already preprocessed.
*
* Used plugins must be also configured in the plugin configuration to be installed automatically. The configuration
* can contain Maven variables replaced by filtering.
