Test methods should not include any locators. Instead of having the following code in a test method selectListBox(SEARCH_MAKE_ID, make);
selectListBox(SEARCH_MODEL_ID, model);
selectListBox(SEARCH_MAXPRICE_ID, price); the test should have selectMake(CAR_MAKE);
selectModel(CAR_MODEL);
selectPrice(CAR_MAXPRICE); See below the code of all 4 methods: public void selectMake(String make) {
 selectListBox(SEARCH_MAKE_ID, make);
}
	
public void selectModel(String model) {
 selectListBox(SEARCH_MODEL_ID, model);
}
	
public void selectPrice(String price) {
 selectListBox(SEARCH_MAXPRICE_ID, price);
}
	
public void selectListBox(By listLocator, String listVisbleText) {

 WebElement listElement = wait.until(ExpectedConditions
 .visibilityOfElementLocated(listLocator));
 Select list = new Select(listElement);
 list.selectByVisibleText(listVisbleText);

}
