How to Select random value from a DropDownList using Selenium or UFT – User friendly Tech help
Requirement:- We need to select random value from a given dropdownlist, to test the functionality how our AUT would behave under varying selection of options.

 |
| DropDownlist + HTML code |
n
nApproach:-
n1.We would take the count of existing options in the weblist/dropdownlist .
n2.Take a random value between 0(starting index of the dropdownlist, we can avoid in our case as we have –Select– at 0 index) and maximum value -1(total available options in the list)
n3.Select the value based on the random value
n
nSame logic would work whether we are using Selenium or UFT as our testing tool.
n
nSolution:-
n(Selenium)
n1.How to take count of items:-
na.We can use Findelements method to return a list of items and further we would use getSize method of list to fetch the count value.
n
//Creating the List object List weblist = driver.findElements(By.xpath(".//*[@id='drpdwnTopics']/option")); //Taking the count of items int iCnt = weblist.size();
n
nb.We can use the Select Class and implement its getOptions method to get the count.
n
Select objSel = new Select(driver.findElement(By.xpath(".//*[@id='drpdwnTopics']"))); List weblist = objSel.getOptions(); //Taking the count of items int iCnt = weblist.size();
n
n2.How to generate random number, we would implement “Random” class and use its nextInt method to output the random number between the given range.
nNote:- nextInt, method would generate number from 0 to upperlimit-1, example nextInt(10), would generate numbers between 0 and 9.

ndriver.get(“http://www.ufthelp.com/p/testpage.html”);
ndriver.manage().window().maximize();
ndriver.manage().timeouts().implicitlyWait(20000, TimeUnit.MILLISECONDS);

@Test
npublic void selectRandom() {
n
//Object of the Dropdownlist
n
nWebElement drpDwnList = driver.findElement(By.xpath(“.//*[@id=’drpdwnTopics’]”));
n//Using FindElements to create a List object
n//List weblist = driver.findElements(By.xpath(“.//*[@id=’drpdwnTopics’]/option”));
n//Using Select Class to fetch the count
nSelect objSel = new Select(drpDwnList);
nList weblist = objSel.getOptions();
n//Taking the count of items
nint iCnt = weblist.size();
n//Using Random class to generate random values
nRandom num = new Random();
nint iSelect = num.nextInt(iCnt);
n//Selecting value from DropDownList
nobjSel.selectByIndex(iSelect);
n//Selected Value
nSystem.out.println(drpDwnList.getAttribute(“value”));
n}n
@AfterTest
npublic void close() {
n
//Closing the browser
n
ndriver.quit();
n}n
}

(UFT)
n1.For taking count of items, we would use GetRoProperty in UFT and pass “all items” to fetch the count
n2. Random number is a Utility object , which generates random number between the given range
n
Code

'Random number is a Utility object , which generates random number between the given range Dim obj Set objList = Browser("creationtime:=0").Page("creationtime:=0").webList("html id:=drpdwnTopics")nfnSelectRandom objList
