How to pick a random test object?

let’s say I have 2 buttons = 2 test objects, and when executing i want the test to decide which one of them will be selected. Now given the fact that i already have this 2 objects defined, how should the code look like?
E.g. i have 2 buttons > “male”, “female”, in a gender page. Whenever i run a test case, the script should pick one of them randomly and continue executing.

Hello,

put objects you want to use randomly into a list and use following code:

List<String> randomObjects = Arrays.asList('Path/To/TestObject1', 'Path/To/TestObject2', 'Path/To/TestObject3')Random rand = new Random()String randomPath = randomObjects.get(rand.nextInt(randomObjects.size()))WebUI.click(findTestObject(randomPath))

randomPath variable will contain one of predefined test objects paths.

**randomPath** variable will contain one of predefined test objects paths.

Can we use findTestObject instead of objects path in arrayList ?

List<TestObjects> randomObjects = Arrays.asList(findTestObject('Path/To/TestObject1'), findTestObject('Path/To/TestObject2'), findTestObject('Path/To/TestObject3'))

so whenever i rename any object it is automatically rename in testcase

Definitely! Nice solution. Just declare it as List<TestObject**>** :slight_smile:

Hi,

Thank you for your help
But I get some errors when running the test cases. Could you please help me resolve it?

Thanks,

The above error message means that you do not have the proper data type(s) for the parameter(s) for the method you are using. As an example, perhaps a parameter is supposed to be an Integer and you are using a String.

You do not have any code showing, so I assume you are using something like below:

List<String> randomObjects = Arrays.asList('Path/To/TestObject1', 'Path/To/TestObject2', 'Path/To/TestObject3')
Random rand = new Random()
String randomPath = randomObjects.get(rand.nextInt(randomObjects.size()))
WebUI.click(findTestObject(randomPath))

The next part of the error message indicates which method you were using:

java.util.Random.call() is applicable for argument types: (java.lang.Class) values: [class java.lang.String]

That’s likely from the line:

String randomPath = randomObjects.get(rand.nextInt(randomObjects.size()))

IMHO, something you are doing in the parameter for the get function is making it a String, and not an Integer:
rand.nextInt(randomObjects.size())

Look at that for a start or give us more information on your concern and your code.
