+ *
+ * Save a screenshot as a base64 encoded PNG with the current state of the browser. Be aware that some Selenium driver
+ * are taking screenshots of the whole document (e.g. phantomjs) and others only of the current viewport. If you want
+ * to always be sure that the screenshot has the size of the whole document, use [wdio-screenshot](https://www.npmjs.com/package/wdio-screenshot)
+ * to enhance this command with that functionality.
+ *
+ * This command also doesn't support the [element screenshot](https://w3c.github.io/webdriver/webdriver-spec.html#take-element-screenshot)
+ * feature yet as it isn't supported by most of the drivers. However the protocol command for it is available
+ * to use (see [elementIdScreenshot](http://webdriver.io/api/protocol/elementIdScreenshot.html)).
+ *
+ * <example>
+    :saveScreenshot.js
+    it('should save a screenshot of the browser view', function () {
+        // receive screenshot as Buffer
+        var screenshot = browser.saveScreenshot(); // returns base64 string buffer
+        fs.writeFileSync('./myShort.png', screenshot)
+
+        // save screenshot to file and receive as Buffer
+        screenshot = browser.saveScreenshot('./snapshot.png');
+
+        // save screenshot to file
+        browser.saveScreenshot('./snapshot.png');
+    });
+ * </example>
+ *
+ * @alias browser.saveScreenshot
+ * @param {Function|String=}   filename    path to the generated image (relative to the execution directory)
+ * @uses protocol/screenshot
+ * @type utility
+ *
