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

Answer 1

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;
}

Answer 2

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.

Answer 3

Improving on @uesports135 answer, "classess" should be a String array.

 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;
    }

Answer 4

Simmilar to previous one, but with java 8 capabilities:

String classes= getDriver().findElement(someSelector).getAttribute("class");
Optional<String> classFindResult = Arrays.stream(elementClasses.split(" ")).filter(el -> el.equals("myClass")).findFirst();
if(openClassFindResult.isPresent()){
    return true;
}
return false;

Answer 5

Based on a common pre-classList javascript technique:

public boolean hasClass(WebElement element, String theClass) {
    return (" " + element.getAttribute("class") + " ").contains(" " + theClass + " ");
}

Answer 6

Try using contains();

String classes = divPubli.getAttribute("class");
assertTrue("The element does not contain .maClass class .publi",classes.contains("maClass"));
