Compound class names not permitted

Question

I am trying to click on travel coupon section in coupondunia website after searching for Paytm and am getting an error:-

Exception in thread "main" org.openqa.selenium.InvalidSelectorException: invalid selector: Compound class names not permitted

Can someone help? Thank you in advance.

This is the code I am using:

driver.get("https://www.coupondunia.in/");
driver.findElement(By.id("header-search-input")).sendKeys("Paytm",Keys.ENTER);
Thread.sleep(3000);
driver.findElement(By.className("fa fa-angle-right filter-icon filter-dropdown-category")).click();

Answer 1

Instead of using Class name you can use the xpath of the element it works fine for me.

driver.get("https://www.coupondunia.in/");
driver.findElement(By.id("header-search-input")).sendKeys("Paytm",Keys.ENTER);
Thread.sleep(3000);
driver.findElement(By.xpath("/html[1]/body[1]/div[8]/div[17]/div[1]/div[2]/div[2]/div[2]/ul[1]/li[3]")).click();

This will help.
