errors when using class names locators. Getting compound classes are not supported

0 votes

I have written a method which will count the no of elements in <divs> and will return the number.

 public int getNumberOfOpenBets() {

     openBetsSlip = driver.findElement(By.id("form_open_bets"));
     openBets = openBetsSlip.findElements(By.className(" cashout_noCash"));
     return openBets.size();
 }

This is the page source:

<form id="form_open_bets" method="post" name="form_open_bets">
    <input type="hidden" value="" name="action">
    <input type="hidden" value="" name="bet_id">
    <input type="hidden" value="" name="cashout_price">
    <input id="target_page" type="hidden" value="" name="target_page">
    <div id="By.id" class="slipWrapper ">
        <div id="openBets_header"></div>
        <div id="cashout_1626" class=" cashout_noCash">
            <div id="cashout_1625" class=" cashout_noCash">
                <div id="cashout_1615" class=" cashout_noCash">
                    <div id="cashout_1614" class=" cashout_noCash">
                        <div id="cashout_1613" class=" cashout_noCash">
                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>
</form>

Below is the error log. Seems like WerbDriver doesn't support spaces in class names. Can anyone please guide me to use CSS selector in order to find the elements?

Compound class names are not supported. Consider searching for one class name and filtering the results or use CSS selectors.

org.openqa.selenium.InvalidSelectorException: Compound class names are not supported. Consider searching for one class name and filtering the results or use CSS selectors.

Pretty straight forward..If your class name includes a space, WebDriver will see it as a "compound selector". Thats why this throws an error: 

By.className(" cashout_noCash")

You should either eliminate the white space in your By.className() locator. This should still find elements you're looking for or you can find using CSS selectors. Something like this will work according to the exception: 

By.cssSelector(".cashout_noCash")
