We are passing a raw value “one” to the add() method of mockedList object. So we need to pass the value as an argument matcher. To do this, we need to use the eq() method of the Matchers class. The eq() method is used to create an argument matcher that matches the argument passed to it. So we need to pass the value “one” to the eq() method as shown below:26verify(mockedList).add(eq("one"));
