chai is not defined in Karma-mocha
I am running my test cases succesfully using mocha-phantomjs configurations. Now I am running these test using Karma launcher. But I get the issue Chai is not defined . Here is my configuration file. module.exports = function(config) { config.set({ client: { mocha: { ui: 'tdd' } }, basePath: '', frameworks: ['mocha'], files: [ 'web/js/*.js', 'test/lib/*.js', 'node_modules/chai/chai.js' //added this on suggestion of the answer in stackoverflow ], exclude: [ ], preprocessors: { }, reporters: ['progress'], port: 9876, colors: true, logLevel: config.LOG_INFO, autoWatch: true, browsers: ['Firefox']
