Earlier in the week, I was sent across a request from one of our Senior Management on what could be a best tool, used for the automation of tests across the spectrum of Web (HTML & Flash), Mobile (iPhone, Android, Windows, etc.) and Web Services. What I could come up on this is the following. People may disagree with these options and may have different opinions and views on it… please feel free to comment and put them through, to improve on the content
Looking into the problem from the requirements viewpoint, I believe Selenium would be the tool best suited for the above automation work. The issue which might go against it, is that their Mobile product is still in Beta, and they are not the best for Web Services Testing, Watir being the frontrunner in the Open Source (i.e., Free) tools in that category. There are other Commercial Tools also which are available with good support and good interface, making it easier for the Automation to be maintained; which is somewhat of a problem with the Open Source tools, if not properly designed initially. Commercial products also have a big following and hence are cost-effective in the long run, although they might be expensive to procure, but getting a resource who is great in an Open Source product can sometimes be a big recruitment headache.
That said, Flash/Flex is a group, which almost with all tools requires a debug/special build to be provided for testing. Each tool has their own quirks and libraries with which the Flash/Flex application needs to be compiled with. So, you might wish to go more into each tools individual ability and reviews of their Flash library functionality; especially for Web Based applications.
Coming to mobile applications, the market for these exists as a very fragmented field for testing successfully. With Android Browser, iPhone Safari, IE Mobile and Firefox being the major browser contenders for the Automation tools available, along with testing of the Apps within the iOS, Android, Windows Phone and the various other vendors out there. I have seen many people refer to the Experitest SeeTestMobile tool, which might be becoming a tool of choice for many, these days.
I plan to go over some of the tools which might help out in each group, and some which might have multiple categories covered below. These opinions are my own through what I have experienced with them, and all are free to criticize and cajole me into making changes as is reflected “great” for them…
Disadvantages: Not very intuitive, depends on coding skills and good design. New WebDriver is good, but there are not many in the market who can create some really good frameworks and know how to use it properly. Requires knowledge of XPath and JUnit type of coding to do anything great with the tool. Mobile product is still in Beta. Not many people available and consultation fees with consultants and resources can be high.
HP Quick Test Pro
Advantages: Well supported and lots of resources available who have certifications, but mostly used in Financial Institutions. Integrated add-ons for Flex, Web Services, Silverlight, and Web HTML. Framework issues can be easily taken care of with Odin AXE framework, which uses XML and simple interface.
Disadvantages: Ability to recognize complex UI and dynamic content hinders the tool. Mostly used in Data-driven web testing, which makes use of Excel sheets; easy for the user to use, but may cause issues in maintainability. Windows System only focused. Not suitable for Unix-Clones and Mac OS. High deployment costs.
MicroFocus / Borland SilkTest
Advantages: Good tool for Web and Flash. (MicroFocus has recently bought it after Borland failed, not sure of its development path going into the future). Has support for other platforms and operating systems.
Disadvantages: Learning curve, due to its test coding language. Not many people available with the tool knowledge.
Advantages: Good Open Source Tool for Web Services and Web Testing. Used with Fitnesse, produces easy to create and support web tests and web services tests. Not too good with Flash and Mobile.
Disadvantages: Uses Ruby as the language of choice, which is a skill getting hard to find for Testing.
Advantages: Great tool for Web testing. Has good variety of plug-ins for the various other technologies. Available as Free version and supported paid version. Support for the same is great, the Developer of the tool is quite helpful in working out the issues with the Test Team. Good for complex websites, where other tools may sometimes fail. Unlike Selenium, it does not make use of XPath to identify objects; and can be used across browsers for recording tests.
Disadvantages: Only used for Web Testing for now. [not sure if it has been updated with plug-ins for others]. Limited use, thus not many people know about it.
Advantages: Great tool for Web Services Testing from Smart Bear.
Disadvantages: Only useful for Web Services Testing. (but this might be an advantage, as they plan to make this a separate activity)
Advantages: Good tool, very similar to HP QTP, with a good interface and price. Overall good for Flash/Flex, with the included Libraries. SmartBear has a full stable of tools, which if bought together may be helpful in pricing and overall deployment and support. Uses VBScript/VBA for coding. People with QTP Experience may find it easy.
Disadvantages: Flash/Flex testing is still not very stable, sometimes fails to recognize the separate objects.
Microsoft Visual Studio Test Professional
Advantages: Is natively attached to the Visual Studio product line. Great for Cloud and .NET application testing. Good is you have Windows Phone applications. “CodedUI” is an excellent tool for testing cross-browser and web HTML testing. MS does deals to get the testing community to start using their tools
Disadvantages: Only for MS Technologies mostly. Not good for Firefox and Android. Only uses C# or Python.
Odin AXE Framework
Advantages: Great tool for building a wrapper over the existing tools scripts; actually it converts the tools identified objects into a XML recognizable format and has a great and easily understandable format for Automation testers.
Disadvantages: None that I can think of for now, except the use of a tool is somewhat a compulsory need for the framework created in AXE to work. Odin has done a good job of making the tool robust for Web Testing tools and it is compatible with almost all other commercial tools available.
Advantages: Combines the best of Requirements, Test Case Design and Test Case execution, all in one single application. Good when there are business testers who know what the application is doing and there is good documentation available for doing it.
Disadvantages: Not very flexible when it comes to handling of unexpected behaviour within the application. Likes to have a clean interface to run through test cases and offer a “happy” path.
I can provide some more research into the new tools (and some less known but good ones), but the above are some of the common ones in use.
I am not advocating the use of any one tool above and to each depends on what he has worked with and would be comfortable in using.
