I am automating the GUI using Robot framework with selinium2Library. I am using selenium IDE and I don't find any record and play option for the Robot framework.
Is it possible for record and play back option for the test cases with Robot framework using selenium2Libbrary instead of writing test cases manually?. Appreciate some early response on this one.
Looks like you might got in confusion because of the work selenium which is different when you use it in RobotFramework.
I believe that you have to write the test cases, and you may Pycharm IDE where you get the context help for the in built as well for the user written keywords when the resources are imported.
However, I remember reading in a thread, but could not trace it. Here you can find article on how you can use Selenium IDE to record, but haven't tried myself. You may try it and see how it goes for you.
But I strongly believe that if you write the test, you can organize them into different reusable keywords than depending on the recording the stuff. Good luck.

Why can't we just record all of our test cases in Selenium IDE, export it to Java/WebDriver and run it in WebDriver with Eclipse?
I need a clear explanation as I am very much confused in using WebDriver!
And can anyone please explain why IDE recorded scripts fail in WebDriver?
why cant we just record all of our test cases in IDE, export it to java/webdriver and run it in webdriver
Great question, and here is the answer:
Selenium IDE is a Record and Playback tool, which is very easy to use, but it's very unreliable. Record and playback is typically a frowned upon in web applications. Since web applications are frequently changed, the IDE is not an ideal solution for a production environment, because of the maintenance nightmare that may arise.
Let me give you a practical example. You record your test, and you find an element with a dynamic ID. Sure we can import it into eclipse, but what happens when that test starts failing down the road? why not simply make your test agile and independent to catch these in the first place.
It also boils down to your principles of test automation. Test automation in MY opinion (and several other professionals), believe that test automation should be approached from a programming perspective. Programmers should write the tests, and maintain the tests. Ideally, your quality assurance personnel should be trained to write and maintain their own tests.
So again, back to your question, the IDE is designed to be a quick solution to automation, NOT a solution to a full regression suite.
And can anyone please explain why IDE recorded scripts fail in Webdriver?
I haven't used the IDE in a while, but the reason they fail, is because the scripts that are exported, are simply the steps, not an entire java file. This also is because Selenium IDE exportations are supposed to be agnostic when it comes to how to run your test. Say I'm a user of jUnit.. what if Selenium IDE exported it to TestNG all the time? That wouldn't be fair.. honestly i'd rather create my own tests than changing that one line every single time i create my test file.
You may read the full text of a research conducted, called Why do Record/Replay Tests
of Web Applications Break?
Why can't we just record all of our test cases in Selenium IDE, export it to Java/WebDriver and run it in WebDriver with Eclipse.
You can actually do this with Selenium IDE quite easily. Record your test case / test suite in Selenium IDE, export to "Java / JUnit 4 / Webdriver" to a .java file. This will generate a JUnit test that you can import and run from Eclipse (with the correct version of JUnit of course).
It's not 100% reliable, and you may need to make some manual changes/corrections, but in general it works pretty well. Start with a single small testcase and work from there.
Why not just record in the IDE and play the recording with WebDriver???
The IDE Does Not Know What to Wait For
Suppose Bob is performing manual checks and recording his interaction with Selenium IDE. He performs an operation that takes a while to update the GUI, and when the operation has finished, he clicks a button. Bob knows that the GUI has finished updating because a spinner that was show when the operation started is removed when the operation is finished. How is the IDE going to capture the fact that the operation must have finished before clicking on the button? (Note here this is not a case where the button is disabled until the operation is finished.) This is not a hypothetical: when you test dynamic tables (like those managed by DataTables), the user can change anything at any time.
This can be one of the reasons a sequence of commands created with the IDE would fail with WebDriver. It just does not know what to wait for.
It is possible to add waits manually in the IDE but if you are doing this, then you are no longer "just record[ing] all of our test cases". And what you are doing becomes more like writing code for WebDriver.
Users are Inefficient
Not long ago there was a Selenium question in which the user wanted to get Selenium to click on the last record in a table that had multiple pages of records. So the question was, how can I page through the table, all the way down to the last page and then click the last record? Someone (maybe me, maybe someone else) pointed out that if the table is sortable, it could be sorted in reverse order and then the Selenium code could click on the first record. That's 2 operations rather than p+1 operations: clicking p times, where p is the number of pages, plus 1 time for the click on the record.
When we write code for WebDriver, we have the opportunity to write the tests to avoid taking the scenic route to get the results we want. See the next point for the technical details as to why it matters.
Selenium Operations Can Be Costly
If the software that runs your Selenium commands is local, and your browser is local, you may not feel that Selenium operations can be costly but if you run your commands on one machine and the browser is remote, then you will notice a significant slowdown. For instance, if you spawn your browser in a Sauce Labs VM or in a BrowserStack VM to run a test suite, network delays are going to add significant time to how long it takes the suite to complete. For a complete application test suite, this can mean many minutes more.
The IDE produces a sequence of commands that each require a round-trip between the Selenium script and the browser. Each round-trip adds up. Suppose I want to check that two elements contain the same text. I'm not going to use Selenese because I don't usually use the IDE but using WebDriver code in Python, the script could be:
a = driver.find_element_by_id("a")
b = driver.find_element_by_id("b")
assert_equal(a.text, b.text)
This code requires 4 round-trips: one round-trip per find_element... and one per access to the text field. The same test could be written:
a_text, b_text = driver.execute_script("""
var a = document.getElementById("a");
var b = document.getElementById("b");
return [a.textcontent, b.textContent];
""");
assert_equal(a_text, b_text);
This needs only one round-trip. When you use the IDE to record actions, the sequence of commands is like the earlier snippet: lots of round-trips. When you write your code for WebDriver, you have the opportunity to optimize as you code.
This does not mean that the Selenium IDE has no use but I would never ever think of just recording tests with it and then playing those recordings with WebDriver.
If you are a newbie, you can actually use 80% of your IDE script as your webdriver JAVA script, u just have to slightly improvise your exported IDE script and it will work fine.
But when you start testing complex functionalities you have to learn some of the basic java methods to work it out!
I beg to differ. I see no reason in having to maintain extra code when a simple record and playback can achieve same results in a fraction of the time.
I do agree with the impl of the recorded script has to be agile. It can't just be as simple as the build in commands and one has to make it agile and even inplement their own macros (aka commands/aliases) specific to the app under test.
Still, if implemented right and with the help of few Selenium IDE plugins like flow control it becomes a breeze to maintain such complex test suits and have them played back via the HTML Runner. I've used Selenium IDE HTML scripts to fully cover complex sites and reused the same script for all responsive modes of the app.
Maintanance is simple as the IDE will help you quickly adjust a failed cmd and AJAX waits can easily be accounted for correctly by waiting for DOM content to change on the page. I'm still not convinced of this AJAX excuse for dismissing Selenium IDE.
For a Maven integration of flow controls command/aliases/macros used by Selenium IDE and Maven's SureFire test plugin see:

Feel free to use it in your product and improve as needed.
webdriver allows you to execute your test cases captured with Selenium IDE in a Selenium server or via RC to multiple servers. This includes options to integrate with Selenium-enabled providers (see link at the bottom).
For example, if you've captured your test case in IDE, you could easily integrate with your own selenium server, or a provider like Saucelabs to handle the running of your test cases in Firefox on Ubuntu, Safari on OSX and IE10 on Windows 8. As with any test case, you can run it from your IDE (Eclipse / IDEA / etc ) your builder (maven / gradle /), and / or via your CI system.
Check out https://saucelabs.com/selenium for some examples. We've also used our selenium test cases for load testing with Soasta - WebDriver allows simple IDE tests to be used in many different contexts.
Because when the complexity of your code will increase, it will be difficult for you to manage it using IDE. Maintenance of your scripts will be difficult using IDE.
Also Exporting test cases from IDE to webdriver is not 100% reliable.
Other people have said a lot of helpful answers. One thing that is missing is that if you write code instead of using the IDE you have the power to make changes to the database. It depends on the website you are testing how useful this is, but here are some useful examples I've experienced. In one case the website had multiple sections of a class. One of our tests was merging these sections into one. The IDE couldn't do this. But with webdriver we can add all of our test data into the database, perform the merge, and then remove the data from the database.
Another advantage that webdriver has is Selenium Grid. With Grid you can run your tests in parallel and on multiple browsers. This makes your testing run faster and you can more thoroughly test the code.
I am new to Selenium and have spent about a week using IDE. So far, so good. However, some other parts of our application involve heavy drag-n-drop capabilities, and I'm not so sure about that...which brings me to my question...what type of specific things can WebDriver do that the IDE cannot do? I read the Selenium front page, and know that WebDriver can make more "robust" tests, but I'm not entirely clear what robust means in this context? Longer? More capabilities?
What I'm looking for is what type of particular tests could be run with WebDriver that couldn't be run in the IDE? And are any of them related to drag-n-drop? This will inform my decision about whether to keep on using the IDE or to switch over. I think it's better to use something from the beginning than to create a lot of tests and then switch over.
Thanks much in advance.
You can use the full features of your chosen language. For example, using the IDE you are stuck to using the IDE's API, however if you choose to use the WebDriver explicitly you can combine it with C# and use C#'s full features (such as LINQ).
A few of the IDE commands are not directly converted with the WebDriver.
You can integrate a pure WebDriver test into a CI (Continuous Integration) server.
It is not limited to just Firefox, whereas the IDE is (since the IDE is only available in Firefox).
You can improve and extend Selenium more easily. For example using Extension methods and inheritance. (For instance, extending Selenium so that whenever it cannot find an element, it takes a screenshot of the page)
It will be more robust, as the IDE will not always give you the most reliable way of finding an element. For instance, if the element you require is nested within a table, the XPath that the IDE will give you will infer directly to specific table rows and cells.
For instance something like this:
//table[1]/tr[1]/td[2]/table[1]/tr[1]/td[3]/a[1]/b
Is not the most reliable XPath in the world. Those without any knowledge of XPath or automated testing or how Selenium works, will stick with that and then waste hours figuring out why this XPath query fails. Others will change it, and just use the XPath as a base query.
The IDE should usually be used for those who don't have much programming knowledge (e.g some testers), if you want your developers and/or the test developer's to use Selenium, go directly with the WebDriver. It will feel more like programming with a fully-fledged language instead of scripting (after all, the scripts that the IDE generates are purely HTML files). The idea is generally for those who don't have much programming knowledge to simply hit 'play' and let Selenium do the work.
Drag-and-drop are applicable within the IDE and WebDriver.
Most of the development in Selenium (it seems) goes into extending the WebDriver code, the IDE may be left behind in some new features.
Using WebDriver directly, you can also use the full features of a unit testing framework (usually NUnit with C# or Junit/TestNG for Java). This allows things like repeating tests for each browser (i.e repeating tests in Chrome, Firefox and IE) or defining certain logic before and after tests (i.e adding user memberships, creating users, setting up other test data).
Fellow developers might be more inclined to help out if it is using a programming language as opposed to a scripting language (ie WebDriver is programmed in a programming language, the IDE scripts are just HTML files). Putting it in your solution and having it as part of the nightly build process helps to ensure developers help out in your tests progression.
Thinking about it, another example is a bug is fixed but introduces a new bug which causes your test to fail. Who's responsibility is it to fix the test? You or them? Having it use WebDriver directly, they can just look up the source code to Selenium and figure out the API usage themselves. With the IDE, it is literally a HTML file that calls some javascipt. Not much documentation on it.
To sum up: if you don't have much programming experience, either learn a language and use WebDriver with it directly, or just stick with the IDE. Either will do the job.
IDE cannot be used for serious automation. I would sussgest learn the API and use it with Java/C#/Python. It will help you churn out some good automation and will payback really well.
You can always use the IDE to learn how the code is generated.
Hi I want differences between architectures of selenium RC and webDriver.
I read lot of functional differences but did not find anything for architecture differences.
If anyone can send/post links of differences that will really appriciate.
Thanks in advance
The difference is quite substantial.
Selenium RC works only using JavaScript for its every command. That means that everything you write is eventually translated into Javascript and run in the browser. This approach has several pros and cons - it should work the same way in every browser, but is limited to "same origin policy" and to JavaScript limitations.
http://seleniumhq.org/docs/05_selenium_rc.html#how-selenium-rc-works
WebDriver actually uses each browser's own and native API's to work with them. That means that it sometimes needs direct help from browser development team, sometimes fails on a new browser version release, sometimes behaves slightly differently on different browsers (but hey, on IE, js was also not the most reliable thing), but is a much stronger tool overall. It should be faster, it should allow for much more complex work without any js limitations.
http://seleniumhq.org/docs/03_webdriver.html#how-does-webdriver-drive-the-browser-compared-to-selenium-rc
Note that while Selenium RC has been oficially deprecated, the WebDriver is now being developed rapidly and it still suffers from several child-illnesses and is not in its full strength. That said, using WebDriver, you can do anything Selenium RC can do. And sometimes more. With an occasional minor bug.
here you can Selenium Webdriver Architecture

you can also find diff. between RC and webdriver below

Though there are many advantages of Page Project Model, some of them worth mentioning are :
Simple and clear page classes with sensible method names.
You can actually give the customize names to you methods. Like above so that you need not to keep anything in mind.
Just looking into the method name gives you all idea about the capabilities of the method.
Makes tests more readable. In comparison to above commands of selenium , where in you need to add all the commands in the tests scripts . in page object model you need to put method names. The methods which you have created according to your understanding of application so these methods name are more readable and easy to understand.
Stay [DRY]
Page object model believes in the principle of Do not repeat yourself.
Good support of tests, because everything is stored in one place.
Easy creation of new tests. In fact, tests can be created by a person not knowing the features of automation tools.
As I have actually implemented it in my project so definitely there are some flaws:
All locators should be kept in page class file.
And this abstraction leads to some chaos with in the Page Class file.
So you need to implement something like key word driven on top of Page Object Model so as to fully take the advantages.
I am currently looking at choosing a automated web testing framework for use with a current web project. I am pretty sure that I am going to use selenium. I have been reading a little about selenium 2.0 or webdriver. Does webdriver have a recorder plugin like selenium 1.0 or is it just an API for web tests?
I would appreciate it if anyone could point me in the direction of some good examples of using it.
Thanks
The maintainers of Selenium, sort of answer this question here:
http://www.viddler.com/explore/saucelabs/videos/27/
Look for timestamp 00:56:00 and 00:43:00
Basically, there will probably be IDE support for Selenium 2 eventually. But it isn't there yet and it's not clear what it will look like.
You should probably be avoiding the IDE anyway. The tests that you record using the IDE tend to be fragile, unmaintainable and hard to read. Once you've learned the basics of Selenium, it's probably better to write your tests in a real programming language.
Have you seen - http://seleniumhq.org/docs/03_webdriver.html and
http://seleniumhq.org/docs/04_webdriver_advanced.html
Using Selenium IDE we can format recorded code in different languages - Selenium IDE > Option > Format
But did not see any formatter for webdriver, though bumped on to this -
https://addons.mozilla.org/en-US/firefox/addon/webdriver-backed-formatters/
Only a few minor adjustments are required to get the existing 1.0 C# scripts running under the 2.0 beta of Selenium.
Check out this blog post
Once the RTW release of Selenium is ready, I'm hoping that a better formatter is ready. Until then, I'm able to use my scripts.
You can use Selenium IDE 1.9.x (I am using 1.9.1) or 1.8.x for recording purpose. And then you can export the recording tests into your desired programming language. For example, if you want to convert your recording code (recorded by Selenium IDE) into C# , follow the steps below:
Click File menu at Selenium IDE
Mouse over "Export Test Case As" and then click "C#/NUnit/WebDriver"
Save the file at your desired location
In the same way, you can convert your code to Java, PHP, Ruby etc.
Note: Some code might not be converted exactly in some cases. In that case, it needs to modify code manually
My project is compatible only with Internet Explorer. I want the test scripts to get generated automatically as it is done in Selenium IDE.
Can i use Selenium RC to test my application? I could not use Selenium IDE as it can be used only with Mozilla Firefox.
seleniumrc works with IE. You can specify the browser and the path to it within the config file.
It can be easily integrated into night builds via ant.
stick to writing the testcase in java.
Selenium RC and Selenium Grid are both really good at running tests against IE. You can see all the browsers that are supported by Selenium here and Selenium is Designed to write for one browser and work in the rest. THere are a few little quirks that wont work in every browser but 99% of the time it will.
Selenium RC works with IE, but is very buggy with IE 6 (to the point of being unusable). Generating the scripts is not trivial and there are many methods of doing it. We have created a Firefox extension that examines objects via introspection to make click recording easy. There are many options out there but your best bet is to write your tests with Firefox/Firebug (or Chrome). They will make object location much simpler and if you are careful the locator strings should still work in IE.
There could be two answer to you question:
Besides Selenium, though it has ample of advantages, I am reading about another tool which uses same API which Selenium use. The only changes in API I have seen so far is it reduces the complexity of functions thus making it more easier and simpler for user who is learning.
The tool is called 'Helium' and it has 50% (and more) less complex functions and code as Selenium has.
The only problem with this tool is it is paid tool for learning purpose and for implementing not-so-big scale project you can use it. But yeah after some time its gonna cost you.
I have implemented some code on Helium. Please let me know , if you face any issue initially or you are thinking to implement it.
Other being, you can use Selenium Builder(http://khyatisehgal.wordpress.com/2014/05/26/selenium-builder-exporting-and-execution/) which is an advanced form of Selenium IDE. It imports your command in different languages and does work more effectively and efficiently as Selenium IDE does(http://khyatisehgal.wordpress.com/2014/05/25/selenium-builder/)
Please let me know , if you have any doubt in any of the tool.
I know Watin is compatible with IE and Firefox. If you want to generate the test code you can use the Watin Test Recorder
This of course is implying that you are using .Net
... Or you could just use the .net bindings that comes along with the latest couple of versions, then you can just run 'em through nUnit.
For ex. Selenium IDE users Katalon Recorder might be a good match. Supports different browsers.
