How to use "while" and "endWhile" command in selenium IDE software testing tool
"while" command is not supported by default in selenium IDE software automation testing tool. Selenium IDE also not supporting any conditional(if condition) commands by default. To get support of "while" loop as a Advanced Selenium IDE feature, You need to attach user extension with selenium IDE software testing tool. You can read my post about how to attach user extension with selenium IDE.
I shared user extension file for "while" loop command. Click here to download selenium IDE user extension file for "while" and "endWhile" Commands and save it in your hard drive(only in .js format)
with name "user-extension.js" and attach it with selenium IDE software automation testing tool as shown in bellow figure.
After attaching selenium IDE user extension file, You need to restart your selenium IDE software automation testing tool's window to get its effect. Once you restart your selenium IDE, you are ready to use "while" and "endWhile" command with selenium IDE. Copy-paste bellow given example script for "while" command in your selenium IDE and run it to view how it works.
| New Test | ||
| Command | Target | Value |
| open | http://docs.seleniumhq.org/ | |
| setSpeed | 1000 | |
| store | 1 | MyVar |
| while | storedVars.MyVar <= 3 | |
| echo | ${MyVar} | |
| highlight | css=img[alt="Selenium Logo"] | |
| store | javascript{storedVars.MyVar++;} | |
| endWhile | ||
(Note : You can look at this selenium IDE tutorial posts to be master in just 7 days).
In above example, look at command execution sequence carefully in selenium IDE software automation testing tool's window. "while" loop will be rotated 3 times and execute all inner(commands between "while" and "endWhile") commands for 3 times. Here syntax, "storedVars.MyVar <= 3" with "while" command will check value of "MyVar" every time and keep running until it becomes <=3. Inner javascript ("javascript{storedVars.MyVar++;}") will increase the value of variable "MyVar" every time by 1 which was set to 1 initially. Above script will high lite selenium logo on selenium site for 3 times.
Can you please tell me how to break while loop in selenium ide?
ReplyDeleteSomething like EXIT or BREAK.
Thanks

You can use "gotoif" command to jump at the end of script when your condition match. You can see how to use "gotoif" command with selenium IDE at http://software-testing-tutorials-automation.blogspot.in/search/label/gotoIf%20Command
DeleteWhile and End while not here in Selenium Ide command.please check and explain.
ReplyDeleteI have run this script but not working properly. I have save the js file and restart the selenium also.
Give me your email id here. Let me send to script for you.
DeleteYour email id is not valid. It shows me message "Delivery to the following recipient failed permanently" when trying to send email. Please give me other id if you have.
DeleteI have run this script but not working properly. I have save the js file and restart the selenium also.
ReplyDeleteIts working for me. I think you have not configured properly.
DeleteI downloaded your user script as well as your rollup script. Then I created a while/endWhile script and turned it into a rollup. This worked fine. Then I created a second while/endWhile script and rolled that up too. Now I get an error when playing the first while/endWhile rollup in a test script. I am using Selenium IDE 2.4.0. See error below.

ReplyDeletei'm using IDE 2.5.0 and have included your user-extension.js
this did work:
store | 1 | MyVar
while | storedVars.MyVar <=10
echo | ${MyVar}
highlight | id=menu1
storeEval | parseInt(storedVars.MyVar) +1 | MyVar
endWhile
I actually figured out why this doesn't work for some and does for others. The problem is when you copy and paste the Target values.
ReplyDeleteFor example on the store javascript{storedVars.MyVar++;} value if you copy and paste a blank space into any of these values it will loop forever because variable name is not the same.
Please trim all your spaces and this will work
Can you help me ?
ReplyDeleteWhen i used while command.
i got error ... unknown command :"while"
The loops works perfectly. But how can I continue with the next case after the loop ends ?
ReplyDeleteI just want to loop a few cases within my test suite.
Above code works in Selenium IDE but not in Selenium RC. Please help me. Thanks.
ReplyDeleteFor selenium RC, you need to use while loop of language which you are using.
Deletehow to loop between the test cases..?...that means transfer control from one test case to another..

ReplyDeleteplz tell me how to prepare documentation in selenium ide????
ReplyDeleteplz tell me how make a report in selenium ide???
ReplyDeletehow do I loop through items in a list? For example, when loop through loading a site and filling out a form, and read one of the fields into the form from a list of values. Does that make sense?
