How to check if element contains specific class attribute

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;}

#EDITAs @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 2Try 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.

The answer provided by @drkthng works but you might have a case where the class name is a subset of another class name. For example:

<li class="list-group-item ng-scope active">text</li>

If you wanted to find the class "item" then the provided answer would give a false positive. You might want to try something like this:

public boolean hasClass(WebElement element, String htmlClass) {    String classes = element.getAttribute("class").split("\\s+");    if (classes != null) {        for (String classAttr: classes) {            if (classAttr.equals(htmlClass)) {                return true;            }        }    }    return false;}

Use javascript: classList.contains

 WebElement element = By.id("id"); String className = "hidden"; JavascriptExecutor js = (JavascriptExecutor) driver; Boolean containsClass = js.executeScript("return arguments[0].classList.contains(arguments[1])", element, className);
