How to check if element contains specific class attribute

Question

How can I check if a selenium web element contains a specific css class.

I have this html li element

<li class="list-group-item ng-scope active" ng-repeat="report in lineageController.reports" ng-click="lineageController.activate(report)" ng-class="{active : lineageController.active == report}"> 

As you can see inside class attribute there is an active class.

My problem is that I have this element and I want to do a check based on if the class attribute has that "active" value among the others, being more elegant solution then using xpath.

How can I do this?

Answer 1

Given you already found your element and you want to check for a certain class inside the class-attribute:

public boolean hasClass(WebElement element) {     String classes = element.getAttribute("class");     for (String c : classes.split(" ")) {         if (c.equals(theClassYouAreSearching)) {             return true;         }     }          return false; } 

#EDIT As @aurelius rightly pointed out, there is an even simpler way (that doesn't work very well):

public boolean elementHasClass(WebElement element, String active) {     return element.getAttribute("class").contains(active); } 

This approach looks simpler but has one big caveat:

As pointed out by @JuanMendes you will run into problems if the class-name you're searching for is a substring of other class-names:

for example class="test-a test-b", searching for class.contains("test") will return true but it should be false

#EDIT 2 Try combining the two code snippets:

public boolean elementHasClass(WebElement element, String active) {     return Arrays.asList(element.getAttribute("class").split(" ")).contains(active); } 

That should fix your caveat.
