/**
 * This node module is run by the karma executable to specify its configuration.
 *
 * The list of files from all needed JavaScript files including the ones from the
 * apps to test, and the test specs will be passed as configuration object.
 *
 * Note that it is possible to test a single app by setting the KARMA_TESTSUITE
 * environment variable to the apps name, for example "core" or "files_encryption".
 * Multiple apps can be specified by separating them with space.
 *
 * Setting the environment variable NOCOVERAGE to 1 will disable the coverage
 * preprocessor, which is needed to be able to debug tests properly in a browser.
