I am a fresher and being hired as a Quality Analyst in a software firm in automation testing
I have been told to study the Selenium tool.
Can you guys help me in knowing that what are the scripting languages I should get in touch so that I can effectively and efficiently use the tool to give the very best output of mine,
Hoping for responses....It would definitely help me a lot in going in proper direction....
Thanks in ADVANCE
Not exactly scripting languages, but be very fluent with HTML and XML/XPath to easily work with pages and understand how they work.
Knowing a little about JavaScript will also come in handy. As for other languages, Selenium natively speaks HTML, but you can write test cases in any of the following languages (list is not exhaustive):
C#
Java
Perl
PHP
Python
Ruby
Native HTML test case can be translated easily to the aforementioned languages, pick whichever you like the most.
You can get all these details from seleniumhq.org site. Please check the documentation section . Also, regardless of the language you choose selenium features remain the same. So choose the language which you are comfortable with.
Adding to what others have already said, to begin programming with your favorite language using Selenium RC, you need to be familiar with the basic Object Orient Programming concepts.
To help you with XPath there are tools like XPather and Firebug which automatically fetch you the XPath of the element.
The perl language binding is quite reliable and up-to-date.
On the CPAN, the current release Test-WWW-Selenium-1.25 is from 28 Apr 2011. It's actively maintained.
Perl's Test Runners and TAP are cool. There are many other testing modules that you can combine with Test-WWW-Selenium.
Using E-P-I-C perl Editor for the Eclipse IDE, you'd get statement completion in your testcase files.
The Perl API calls are written in a slightly different naming convention: for instance, getEval becomes get_eval
but this is a minor point.
IMHO, the perl code template that Selenium IDE generates for you is ok, it can be adapted. (e.g. I prefer Test::Fatal instead of Test::Exception.)
Cannot say anything about the other language bindings.
Choose the language you are most familiar with, and start building up your expert knowledge of testing tricks, Selenium and browser idiosyncrasies. this will take a lot of time anyway.
For any kind of strong automation, you should know atleast one scripting language like JavaScript, VBScript etc... and one full fledged programming language like Java, C# etc.. benefit of learning java or #C is ... you are comfortable in developing complex solutions because of their OOP nature and Java,C# are widely used in IT Industry.
Robot Framework is a robust scripting engine and reporting tool for automation testing.

i am learning selenium concepts.while in the process i am not able to decide to go for which programming language.
1- JAVA or 2- PHP
i have worked on PHP and have gud knowledge about it.so please tell me which is the good one php or JAVA and why???
Well the decission is not only yours. In my own example, I have chosen Java programming language.
Not because I have experience with it.
Not because I might have feeling, that "java is better than PHP"
Simply because all developers in my company work in Java. And because I need help with programming, it is almost always better idea to first ask around in the office than to post your question here on StackOverflow :)
I use groovy(he simply of java), and i use Geb freamwork for this.
You can read about this tool there: link
Enjoy!!!
Well decision is your own. In selenium choose programing language in which you have sufficient knowledge and you have a grip on the language.
Both programing language is good and both have its own scope in the market
What open source software should I use to write scripts to test for no errors on a site?
Could I / we write something better ourselves if there a limited number of goals outlined?
- yet flexible enough to take on new rules etc.
The only consistent response we want is no errors, period.
I know Java, ASP and scripting languages if that helps.
Thanks!
Selenium is one good Website automated testing tool. It allows macros as well as hand-written scripts. Also has support for Firefox browser.
Understanding of Java should suffice.
You can check it out at http://seleniumhq.org/
Another good open source alternative is HTMLUnit http://htmlunit.sourceforge.net/
Again this requires knowledge of Java
You might want to consider the robotframework, combined with the selenium2library keyword library. It lets you write very human-readable tests and gives very nice reports. It integrates nicely with jenkins. Robotframework is written in python, and can be extended with python. It allows you to create data driven tests, BDD-style tests, or more traditional procedural tests.
I have been working on Test Automation from last few months and have been using the tool named "Testcomplete". But I have noticed that the tools do not matter a lot in the field of automation. Only thing you expect from an automation tool is the ability of the tool to spit out the recognition strings for the different controls used in the test application.
Apart from this, you will always have to build a automation framework which will serve your needs writing code.
So my question is, Is my thinking that automation tools do not matter a lot in the field of automation correct? In the sense, you can use any tools to get your automation running. Or Do the tools really matter? (Please ignore the costs factor of the tools). Also if I need to learn a new automation tool, then what do I concentrate on? Or how do I go about learing the tool? In short, what exactly does "learning a tool" mean?
My 3 best reasons for choosing which tool to use:
it works. This is important, not all tools work in all scenarios i.e. flash, silver light, adobe air, legacy apps with no automation support, etc.
whole team skills. This includes not only testers, but also developers. Test automation shouldn't be an isolated effort, developers should also collaborate on it. This is far easier when dev and test are using the same language/platform.
price. Doesn't have to be free (but it could), but of course its an important factor.
Personally we use the same test runner as the one for the unit tests. That along with extra third party automation pieces that do the plumbing for you.
Some additional thoughts on why the tool is important:
Community - What's the user community like? Are there a lot of user-generated resources out there to help?
Support - (if vendor) What's customer support like? Do they fix problems quickly? Is it easy to find solutions to common problems?
Extensibility - Often in test automation, you'll need to roll your own or code work-arounds, if the tool does not support a particular type of object in your application. How easy is it to extend the product? What programming language does the tool use? What kind of support do you get from the IDE?
An other piece of advice: sometimes you'll need wrapper classes around certain frameworks. We were using WatiN, which was really good at its time, but it lacked Chrome (it had a small percentage that time) support. The thing that killed WatiN for us was the lack of coping with new FireFox releases: FireFox 8 was out, and we had to run on our tests on FireFox 3.6...
Selenium was the solution, but it had a totally different logic and we already had more than a 1000 tests.
So we had to create a wrapper class around Selenium to "fake" it was WatiN. We had some issues, but we had to rewrite only some special cases... And not all tests.
The point is, sometimes, support for frameworks just cease to exist. But with an own framework focusing on what the test actually does instead of how it works would save you in this situation.
Variety of Test Automation Frameworks and Test Automation Tools are already available in the market. Thus, I would not recommend the built your own Test Automation Framework at all.
As far as selection of automation tools is a concern, I would say it does matter on the following basis:
Support: How much level of support you have when you are choosing an automation tool for your project.
Community: How big community is using that tool and how responsive that community is about sharing knowledge?
Pricing: (Proprietary or Open Source) Last but not the least is the pricing of the automation tool that you are planning to introduce in your project.
QA teams' expertise also matters sometimes. For example, in case your QA team does not have a developer or semi-developer skills vs Not-Technical QA Team, etc.
Regarding the Automation framework, there are many automation frameworks also available in the market already, therefore no need to reinvent the wheel. and selection of automation framework mostly depends on your selection of scripting language.
For example, if you choose python as your scripting language, then you have option to choose UnitTest, PyTest etc. as an automation framework.
In case of Java, you have option of JUnit and TestNG as an automation framework.
and so on, the base on your selection of scripting language.
Finally, when it comes to structuring your automation framework, it solely depends on many things as the following:
Your nature of the project
Single product vs multiple products
and many more...
Check an example of multiple product automation project directory structure. https://github.com/pancht/python-selenium-framework
I hope, in some way, I would have helped you out in giving an answer to your question.

As already discussed in "Lua as a general-purpose scripting language?" Lua currently probably isn't the best scripting language for the desktop environment.
But what do you think about the future? Will Lua get so popular that there will soon be enough libraries to be able to use it like Python, Ruby or something similar?
Or will it simply stay in it's WoW niche and that's it?
I think it has a great future, a lot of projects are starting to adopt it for it's simplicity and usefulness.
Example: Awesome WM (Window Manager)
The project recently released version 3, incorporating a new configuration system completely written in Lua. Allowing you to literally write your configuration file as a program, loops, booleans, data structures.
Personally I love the syntax and the flexibility of such a system, I think it has great potential.
I wouldn't be surprised if it became more popular in the future.

I suppose the answer starts with 'It depends how you want to use it...'.
If you're writing the common business app (fetch the data from the database, display the data in a web page or window, save the data to the database), Lua already has what you need.
The Kepler Project contains goodies for web development. Check out their modules to see some of the available libraries - there's network, MVC, DBMS access, XML, zip, WSAPI, docs...
As an example web app, check out Sputnik.
For desktop UI, there's wxLua - Lua hooks for wxWidgets.
ORM is conspicuously missing but that didn't stop people from developing in other languages before ORM was available.
If you're looking for specialized libraries - scientific, multimedia , security - don't count Lua out before you check LuaForge.
When it comes down to it, there's nothing in Lua's design that prevents general purpose use. It just happens to be small, fast, and easy to embed... so people do.
Uh? I would say instead WoW is a niche in the Lua ecosystem... The world of Lua doesn't revolve around WoW, there are lot of applications, some big like Adobe Lightroom (to take a non game), using Lua.
Lua is initially a scripting language, in the initial sense, ie. made to be embedded in an application to script it. But it is also designed as an extensible language, so we will see progressively more and more bindings of various libraries for various purposes.
But you will never get an official big distribution with batteries included, like Python or Perl, because it is just not the philosophy of the authors.
Which doesn't prevent other people to make distributions including lot of features out of the box (for Windows, particularly, where it is difficult to build the softwares).
Lot of people already use it for general system-level scripting, desktop applications, and such anyway.
There are more and more libraries for Lua.
If you are a Windows user, have look at Lua for Windows. It comes with "batteries included" (wxLua, LuaCURL, LuaUnit, getopt, LuaXML, LPeg...).
Very usefull!
It's 2017, 9 years after this question was first asked, and lua is now being heavily used in the field of machine learning due to the Torch library.
I really like it as an embedded language. It's small, very easy to use and embed and mostly does what I need right out of the box. It's also similar enough to most languages that it has never really been an issue for me. I also like how easy it is to redefine and add base functions and keywords to the language to suit whatever needs my application has.
I have used it in the WoW area but I've also found it useful as a generic scripting language for a number of different applications I've worked on, including as a type of database trigger. I like Ruby and Python and other more full-featured scripting languages but they're not nearly as convenient for embedding in small applications to give users more options for customizing their environments.
being comfortable as a shell language has nothing to do with being a great general purpose language.
i, for one, don't use it embedded in other applications; i write my applications in Lua, and anything 'extra' is a special-purpose library, either in Lua or in C.
Also, being 'popular' isn't so important. in the Lua-users list periodically someone appears that says "Lua won't be popular unless it does X!", and the usual answer is either: "great!, write it!", or "already discussed and rejected".
I think the great feature of Lua is, that it is very easily extensible. It is very easy to add the Lua interpreter to a program of your own (e.g. one written in C, C++ or Obj-C) and with just a few lines of code, you can give Lua access to any system resource you can think of. E.g. Lua offers no function to do xxx. Write one and make it available to Lua. But it's also possible the other way round. Write your own Lua extension in a language of your choice (one that is compilable), compile it into a native library, load the library within Lua and you can use the function.
That said, Lua might not be the best choice as a standalone crossplatform language. But Lua is a great language to add scripting support to your application in a crossplatform manner (if your app is crossplatform, the better!). I think Lua will have a future and I think you can expect that this language will constantly gain popularity in the long run.
Warhammer Online, and World of Warcraft use it for their addon language I believe.
I think it's hot! I'm just no good at it!
Well, greetings from 2022.
It is already a general purpose language. Today you can even serve pages using OpenResty, extend games, read databases or create scripts as shellscript replacements.
There are a plenty of libraries "modules" for Lua, many ways to achieve what you are wanting and Lua 5.4 is even faster.
The "extendable and extensive" nature of Lua, accostumed people to think it should only be used as plugin or extension. In Linux, by example, you can shebang a file with lua-any, make it executable and run like any system script. Or you can make a folder app like Python or virtualenv using Lupe. Lua 5.3 also gained impressive performance improvements.
Also there are many good tools like IUP to create native windows in Lua for Mac, BSD, Linux and Windows and side environments like Terra that lets you use Lua with its counterpart Terra and write compiled programs. Lua now, is more than a extension language, it has its own universe.
I do mostly Java and C/C++ development, but I'm starting to do more web development (PHP, Rails) and Eiffel (learning a new language is always good).
Currently, I use Eclipse for Java, C/C++, and Ruby (not Rails). Since I know the environment, I'm thinking that it would be easier for me to find a plugin and use Eclipse for all of my development languages. But are there cases where a language-specific IDE (EiffelStudio for Eiffel, as an example) would be better than Eclipse?
I have used many many IDE's and in most cases to me it breaks down to personal preferences. Sometimes the language specific ones have some addins/addons/features that are nice but unless they are things you can not live without you should go with what is most comfortable for you.
I would think that if you are comfortable with the multi-language IDE it would be better to stick with that one. This way you dont have to memorize multiple IDE layouts, keyboard shortcuts etc.
Mastering an IDE takes time and energy. Using a multi-language IDE is definitively beneficial for a programmer who needs to develop in several languages. It is for the same reason that tools like VI and Emacs are so popular.
On the other side, IDE specialized in one language could sometimes go much further on some aspect and could be the preferred choice in some situations.
I love Eclipse as Java IDE (so much that we decided to build some Eclipse based application) and I'm an Emacs fan. But I also like the Groovy support of IntelliJ and the efficiency of EiffelStudio.
It's a matter of taste, you forgive the ones you love...
It entirely depends on the user and the language itself, if you are comfortable with the keyboard shortcuts then you can consider the plugin else you can go for a IDE . However most of the IDE comes with a cross-functional key maps so you use the key maps which u are more comfortable with....
