How to Performance Test Automation for GWT and SmartGWT

The next “evolutionary” step is to monitor performance for every end user

This article is based on the experience of Jan Swaelens, Software Architect at Sofico. He is responsible for automatic performance testing of the company's new web platform based on GWT and SmartGWT. Sofico is specialized in software solutions for automotive finance, leasing, fleet and mobility management companies.

Choosing GWT and SmartGWT over Other Technologies
About two years ago Sofico started a project to replace its rich desktop application (built with PowerBuilder) with a browseribased rich Internet application. The developers selected GWT and SmartGWT as core technologies to leverage their in-house Java expertise because they believed in the potential of what these (fairly) new technologies had to offer. Their goal was to replace the existing desktop client with a new one that ran in a browser. Their eyes where set on a better user experience and high degree of customization possibilities to give their customers the flexibility and adaptability that they need to run their businesses.

Need End-to-End Visibility into GWT Black Box
GWT was a great choice as they could soon deliver the first basic version. The problems started when trying to figure out what was actually going on in these frameworks in order to analyze performance problems reported by the first testers.

Developers started off by using the "usual suspects" - browser-specific Dev Tools for Chrome, Firefox and IE. Back then, the built-in tools lacked first class JavaScript performance analysis capabilities which made it difficult to analyze a complex browser application. Additionally, there were no integration capabilities into server-side performance analysis tools such as JProfiler which would allow them to analyze the impact and correlation between server-side and client-side GWT code. Taking performance seriously, the performance automation team came up with some key requirements for additional tooling and process support.

Requirement #1: Browser to Database Visibility to "understand" what's going on
Do you know what really happens when a page of a GWT application is loaded? No?! Neither did the developers from Sofico. Getting insight into the "Black Box" was therefore the first requirement because they wanted to understand: what really happens in the browser, how many resources are downloaded from the web server, which transactions make it to the app server, what requests are cached, where is it cached and how the business logic and data access layer implementation impacts end user experience.

The following screenshots show the current implementation using dynaTrace (sign up for the free trial), which gives the developers full visibility from the browser to the web, app and database server. The Transaction Flow visualizes how individual requests or page loads and services by the different application tiers are processed.

End-to-End Visibility gave the developers more insight into how their GWT Application really works and what happens when pages are loaded or users interact with certain features.

A great view for front-end developers is the timeline view that shows what happens in a browser when a page gets loaded, when a user clicks a button that executes AJAX Requests, or when backend JavaScript continuously updates the page. It gives insight into performance problems of JavaScript code, inefficient use of resources (JS, CSS, Images...) and highlights whether certain requests just take a very long time on the server-side implementation:

Developers love the timeline view as it is easy to see what work is done by the browser, where performance hotspots are and even provides screenshots at certain events

Requirement #2: JavaScript Performance Data to Optimize Framework Usage

Requirement #3: Correlated Server-Side Performance Data

Requirement #4: Automation, Automation, Automation

Next Step: Real User Monitoring
Giving developers the tools they need to build optimized and fast websites is great. Having a test framework that automatically verifies that performance metrics are always met is even better. Ultimately you also want to monitor performance of your real end users. The next "evolutionary" step therefore is to monitor performance for every end user, from all different geographical regions and all browsers they use. The following shows a dashboard that provides a high level analytics view of actual users. In case there are problems from specific regions, browser types, or specific web site features, you can drill down to the JavaScript error, long running method, problematic SQL Statement or thrown Exception.

After test automation comes production: You want to make sure to also monitor your real users and catch problems not found in testing
