Find div element by multiple class names?

Question

I\'d like to identify that web element. It only has this two classes defined. I cannot do the following as className

Answer 1

Class By.ByClassName

Class By.ByClassName is defined in By.java as follows:

/**
 * Find elements based on the value of the "class" attribute. If an element has multiple classes, then
 * this will match against each of them. For example, if the value is "one two onone", then the
 * class names "one" and "two" will match.
 *
 * @param className The value of the "class" attribute to search for.
 * @return A By which locates elements by the value of the "class" attribute.
 */
public static By className(String className) {
  return new ByClassName(className);
}

This usecase

So as per the defination you can't pass multiple classes i.e. value and test as arguments to @FindBy(className = "..."). Sending multiple classes will raise an error as:

invalid selector: Compound class names not permitted

Solution

There are multiple approaches to solve this usecase as follows:

• If the element is uniquely identified only through the classname value you can use:

  @FindBy(className = "value")
  @CacheLookup
  private WebElement test;
  

• If the element is uniquely identified only through the classname test you can use:

  @FindBy(className = "test")
  @CacheLookup
  private WebElement test;
  

• If both the classnames, value and test are mandatory to identify the element, you can use css-selectors as follows:

  @FindBy(css  = ".value.test")
  @CacheLookup
  private WebElement test;
  

• As an alternative you can also use xpath as follows:

  @FindBy(xpath   = "//*[@class='value test']")
  @CacheLookup
  private WebElement test;
