Web Browser Automation Tools

There are many Web Browser Automation Tools, both paid and free / open source

Web Browser Automation is a process where certain steps in the web browser are performed repetitively to ensure the correct operation of the web application’s functionality. It may be applied for QA testing in the development process and for control over Information System accessibility and performance during implementation. The second becomes more and more important since current market trends indicate that just having a good service is not enough; the service should also be highly accessible and effective. With Web Browser Automation Tools it is possible to check accessibility and performance by periodically running some transaction scenarios for certain services.

There are many Web Browser Automation Tools, both paid and free / open source. The main purpose of these tools is to record a specific transaction scenario for a browser, play it back by injecting JavaScript into web pages and then to provide the corresponding results. The tools vary in many characteristics: OS platform support, supported programming languages, SSL support, whether it uses a real web browser or simulates the real browser’s behavior, etc. Below are presented a relative comparison of some popular free/open source tool’s characteristics.

Tool Simulation Supported Browsers Supported Languages Test Recorder
Selenium No Firefox, IE(partially), Opera (partially), Chrome (partially)[1] C#, Java, Perl, PHP, Python, Ruby Yes
Watij No On Windows only IE, On Linux only Firefox,
On Mac only Safari
java No
Windmill No Python and JavaScript Python, JavaScript, Ruby Yes
Watir No On Windows only IE, Watir Web Driver -IE/FF/Chrome/Safari Ruby Yes
Watin No IE, Chrome, Firefox .net platform languages Yes
Sahi No IE, Safari, Firefox, Chrome, Opera Java, Javascript Yes
Canoo WebTest Yes No need Javascript, Python Yes
CasperJS Yes No need Javascript Yes

Selenium’s different products are compatible, at least partially, with a variety of different browsers, but all of them are fully compatible with Firefox.


Aside from their variation in functionality, these tools have another essential difference. Some of them are headless, which means that they simulate browser behavior. For example, the CasperJS tool uses WebKit engine capabilities to simulate certain test cases. On one hand, headless tools are more productive, but on the other hand, the simulation may generate different results than those of the real browser.
Different tools have their specific advantages. Some of them work with different browsers without significant deviation or trouble; others provide higher performance, etc. There are many articles/posts comparing the pros and cons of web automation tools, but it would also be interesting to compare their performance. We have tested 3 different tools: Selenium, Watij and Casperjs on the same host with the following parameters: Windows 7 32 bit, 4 Gb RAM and the Intel i5 CPU. From these 3 tools, Selenium may currently be the most popular and richly featured, and it offers several products such as IDE, API, Remote Control server (to accept HTTP requests for the browser), Grid server (to test different browser instances running on remote machines), etc. Casperjs is a headless Phantomjs based tool and the Watij is Watir’s java version based on JXbrowser (a rich web browser component to integrate to Java).

To test the tools, we used 45 transaction instances with the same scenario of 7 steps (navigation, clicks, login, logout, etc.). A single transaction execution period was 5 minutes and the overall test duration was 20 minutes. Each tool was tested 2 times: first by running with 1 thread and then with 5 threads. The test results are shown below:
Tool Num. of tests Browsers App run duration Num. of threads Test frequency (min) Transaction step count Num. of tests running during 20 mins Avg. exec time for 1 test (sec)
Watij 45 IE 20 min 5 5 7 34 29.7
Watij 45 IE 20 min 1 5 7 32 33.2
Selenium 45 IE 20 min 5 5 7 - -
Selenium 45 IE 20 min 1 5 7 68 17.6
CasperJS 45 NA 20 min 5 5 7 204 17.1
CasperJS 45 NA 20 min 1 5 7 68 17.2

As you can see, the test results for Selenium with IE browser are absent. The problem was that the Selenium couldn’t run several transaction tests at the same time. Instead of opening several browser instances, it mixes all of them in one browser instance. However, it doesn’t have this kind of problem when working with Firefox or Chrome. For example, running the Selenium with the same conditions but on the Firefox browser, the following results were obtained: average execution time of 1 test is 15.1 seconds, the number of tests run during 20 minutes is 50. The average running time of one transaction test for these tools is not greater than that of the others. The other 2 tools spent a substantial amount of overhead time communicating with the server, starting browser instances, etc.

Examining the performance of selected Web Automation Tools shows that they differ not only in terms of functionality, but that they also behave differently in different conditions (depending on OS, browser type, multithread or singlethread). The main limitation we noticed with Selenium is that it’s primarily designed for Firefox. All of its products support Firefox, and as we have already seen it has problems working with IE. On the other hand the Casperjs is headless and is Webkit based, so it will not work on IE only sites, for example. Meanwhile, Watij works with only one unique browser type per OS (IE on Windows, Firefox on Linux and Safari on Mac). Working with different transaction scenarios simultaneously is much more productive with the headless tools since they consume less time.

We’re entering a new era of computing technology that many are calling the Internet of Things (IoT). Machine to machine, machine to infrastructure, machine to environment, the Internet of Everything, the Internet of Intelligent Things, intelligent systems – call it what you want, but it’s happening, and its potential is huge. IoT is comprised of smart machines interacting and communicating with other machines, objects, environments and infrastructures. As a result, huge volumes of data are being generated, and that data is being processed into useful actions that can “command and control” thi...
