Use of Label & While Loop with Selenium IDE

To use the Labels & While Loop functionality with Selenium IDE we need to configure the following code as .js file.

Below are the Steps :-

1) Open Selenium IDE as Mozilla Firefox Add on.

2) Copy & Paste below given code, save file with extension as .js

3) Go to options , Browse the saved .js file from selenium core extensions field.

Like this :- C:\Documents and Settings\goto_sel_ide.js

4) Now you have to reopen Selenium IDE to use of Labels & while loop

5) You can add code as :-

Selenium Pattern view :-

echo Login done

gotolabel test

echo Gaurav is doing practice

label test

store 20 a

store 25 b

while storedVars['a'] <= storedVars['b']

getEval storedVars['a'] = ${a}+1;

endWhile

getEval alert("Finished");

echo $a

Java language View :-

// selenium.gotolabel("test");

System.out.println("Gaurav is doing practice");

// selenium.label("test");

String a = "20";

String b = "25";

// selenium.while("storedVars['a'] <= storedVars['b']");

// selenium.endWhile();

System.out.println("$a");
