+# Confirure unit tests for gitlab runner
+
+1. Create another Karma config file `karma-ci.conf.js` that will be used by gitlab-runner. In this configuration we will use `puppeteer` instead of usual Chrome browser:
+
+karma-ci.conf.js
+```
+process.env.CHROME_BIN = require('puppeteer').executablePath();
+
+module.exports = config => {
+    config.set({
+        basePath: './js',
+        frameworks: ['jasmine'],
+        files: [
+            '**/*.js'
+        ],
+        exclude: [
+            'main.js'
+        ],
+        preprocessors: {},
+        reporters: ['progress'],
+        port: 9876,
+        colors: true,
+        logLevel: config.LOG_INFO,
+        autoWatch: true,
+        browsers: ['Chrome'],
+        customLaunchers: {
+            Chrome: {
+                base: 'ChromeHeadless',
+                flags: ['--no-sandbox']
+            }
+        },
+        singleRun: true,
+        concurrency: Infinity
+    });
+};
+```
+
+2. Add `test-ci` command to `package.json`
+
+```
+"scripts": {
+  "test": "karma start karma.conf.js",
+  "protractor": "protractor e2e-tests/protractor.conf.js",
+  "start": "http-server . -a localhost -p 8000 -c-1",
+  "test-ci": "karma start karma-ci.conf.js"
+ },
+```
+
+3. Push changes to the repository, then you can see a new pipeline:
