[英]NullpointerException while invoking SendKeys through Selenium using PageFactory with Page Object
[英]NullPointerException using Page Object Model in Selenium
我目前正在嘗試通過在其中實現Page Object Model來改進Selenium測試用例。 但是,我正在測試的網站處理許多模式。 當我嘗試訪問某些模態時,出現NullPointerException。 我無法確定驅動程序是否在等待元素或什么。
這是我的課程:
頁面對象
public class ManualShipmentModal
{
WebDriver driver;
WebDriverWait wait;
@FindBy(id = "manual-order-modal")
WebElement modalBody;
@FindBy(name = "mailToName")
WebElement toName;
/* Constructor */
public ManualShipmentModal(WebDriver driver)
{
this.driver = driver;
driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
AjaxElementLocatorFactory factory = new AjaxElementLocatorFactory(driver, 100);
PageFactory.initElements(factory, this);
}
public boolean modalExists()
{
return modalBody.isDisplayed();
}
public void enterToAddress(String toName, String addressName)
{
wait.until(ExpectedConditions.visibilityOf(modalBody));
WebElement toAddress = driver.findElement(By.linkText(addressName));
this.toName.sendKeys(toName);
toAddress.click();
}
}
測試班
public class TEST_11
{
WebDriver driver;
LoginPage loginPageObj;
HeaderMenu headerMenuObj;
ManualShipmentModal manualShipmentModalObj;
@Before
public void setup()
{
driver = new ChromeDriver();
driver.get("testpage.com");
}
@Test
public void testCreateNewShipment()
{
loginPageObj = new LoginPage(driver);
headerMenuObj = new HeaderMenu(driver);
manualShipmentModalObj = new ManualShipmentModal(driver);
loginPageObj.login("username", "password");
headerMenuObj.createNewShipment();
manualShipmentModalObj.enterToAddress("Test", "The Usual Test");
}
@After
public void teardown()
{
driver.close();
}
}
運行正常,直到我調用enterToAddress()。 當達到這一點時,它將引發NullPointerException。 即使我定義了隱式等待和顯式等待,驅動程序似乎也不在等待元素加載。
WebDriverWait wait
未實例化,因此調用它會引發NullPointerException
。
在ManualShipmentModal
的構造函數中使用其構造函數:
public ManualShipmentModal(WebDriver driver)
{
this.driver = driver;
long timeOutInSeconds = 10; // just an arbitrary value example
this.wait = new WebDriverWait(driver, timeOutInSeconds);
// the rest of your constructor as in the original code
driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
AjaxElementLocatorFactory factory = new AjaxElementLocatorFactory(driver, 100);
PageFactory.initElements(factory, this);
}
