java.lang.NullPointerException when try click

Question

I get java.lang.NullPointerException when I try use method getClickOnHotelTab()

The method getClickOnHotelPage is on the page SearchHotelPage. When I try use this method on SearchHotelStep I got java.lang.NullPointerException.

This is my SearchHotelPage:

public class SearchHotelPage {

public WebDriver driver;

private By clickOnHotelTab = By.xpath("//*[@id='PageNavBarSectionList']//a[@title='Hotéis']");
private By destinyClick1 = By.xpath("(//div[@role='button']/span)[3]");
private By destinyClick2 = By.xpath("//input[@placeholder='Destino ou nome do hotel']");

public SearchHotelPage(WebDriver driver) {
    this.driver = driver;
}

public WebElement getDestinyClick1() {
    return driver.findElement(destinyClick1);
}

public WebElement getDestinyClick2() {
    return driver.findElement(destinyClick2);
}

public WebElement getClickOnHotelTab() {
    return driver.findElement(clickOnHotelTab);
}

---

This is my SearchHotelStep:

@RunWith(Cucumber.class)
public class SearchHotelStep extends BasePage {

public WebDriver driver;

@When("^Choose destiny or hotel name$")
public void choose_destiny_or_hotel_name() throws Throwable {
    
    SearchHotelPage destinyClick = new SearchHotelPage(driver);
    destinyClick.getClickOnHotelTab().click();
    //destinyClick.getDestinyClick1();
    //destinyClick.getDestinyClick2().sendKeys("cancun");
    //destinyClick.getDestinyClick2().click();
}

This is the output:

Can you help me, please ?

Answer 1

I am unsure how selenium works, but it looks like the WebDriver driver variable is never assigned or created in your SearchHotelStep class, so it will always create a null pointer error.

You need to create or assign the driver before you use it.

For example driver = yourCreatedDriver; or public WebDriver driver = new WebDriver(...);

Something like this:

@RunWith(Cucumber.class)
public class SearchHotelStep extends BasePage {

public WebDriver driver = new WebDriver(...);

@When("^Choose destiny or hotel name$")
public void choose_destiny_or_hotel_name() throws Throwable {
    
    SearchHotelPage destinyClick = new SearchHotelPage(driver);
    destinyClick.getClickOnHotelTab().click();
}
