运行多个测试时无效的会话ID [英] Invalid session id when running multiple tests
问题描述
我之前曾提过这个问题，但似乎没人能回答.因此，我将继续对当前的代码结构再发表一个问题:
I have raised that question previously, but nobody seemed to be able to answer it. Therefore I will go ahead and post a question one more time with the current code structure:
我有一个具有@BeforeEach方法的父母，该方法可以设置所有内容:
I have a parent with a @BeforeEach method that sets up everything:
public class WebDriverSettings {
public static WebDriver driver;
@BeforeEach
public void setUp() {
WebDriverManager.chromedriver().setup();
driver = new ChromeDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(4, TimeUnit.SECONDS);
loginToEnvironment();
}
@AfterEach
public void tearDown(){
driver.manage().deleteAllCookies();
driver.close();
}
private void loginToEnvironment() {
String TARGET_URL = System.getProperty("TARGET_URL", "");
String URL = " + "@" + TARGET_URL;
driver.get(URL);
}
比父母的孩子还多，其中一个测试类:
Than it's a parent's child, one of the tests classes:
public class LoginServiceTest extends WebDriverSettings {
private LoginModal loginModal;
@BeforeEach
public void setUp() {
super.setUp();
loginModal = HomePage.homepageInstance(driver)
.acceptCookies()
.closeCovidMessage()
.clickOnMyAccountTab()
.switchToLoginTab();
}
@Test
public void shouldSuccessfullyLogin() {
assertEquals(userName, loginModal.login(loginCorrectData()).myAccountName.getText());
}
@Test
public void shouldDisplayIncorrectCredentialsMessage() {
loginModal.login(loginIncorrectData());
assertEquals(incorrectCredentialsMessage,loginModal.wrongCredentials.getText());
}
pom对象的示例，通过这种方式构建我所有的pom对象:
Example of pom object, in which way all my pom objects are build :
ublic class LoginModal extends BasePage {
private static LoginModal loginModal;
@FindBy(xpath = "//input[@name='email']")
public WebElement emailInputField;
@FindBy(xpath = "//input[@name='password']")
public WebElement passwordInputField;
@FindBy(css = ".button-hover-wrapper > div.button-inner")
public WebElement loginButton;
@FindBy(xpath = "//a[text()='Log In']")
public WebElement loginTab;
@FindBy(css = ".error-info")
public WebElement wrongCredentials;
private LoginModal(WebDriver driver) {
super(driver);
}
public static LoginModal loginModalInstance(WebDriver driver) {
return loginModal == null ? loginModal = new LoginModal(driver) : loginModal;
}
public HomePage login(Login login) {
loginModal.clickOnLoginTab()
.fillInEmail(login.getEmail())
.fillInPassword(login.getPassword())
.clickOnLoginButton();
return HomePage.homepageInstance(driver);
}
public LoginModal clickOnLoginTab() {
loginModal.loginTab.click();
return loginModal;
}
public LoginModal fillInEmail(String email) {
loginModal.emailInputField.clear();
loginModal.emailInputField.sendKeys(email);
return loginModal;
}
public LoginModal fillInPassword(String password) {
loginModal.passwordInputField.clear();
loginModal.passwordInputField.sendKeys(password);
return loginModal;
}
public void clickOnLoginButton() {
loginModal.loginButton.click();
}
}
据我了解，我的代码执行以下操作:
From my understanding, my code does the following:
setUp方法每次在测试之前运行，子级中的setUp方法开始运行，这将成功打开浏览器并完成测试.但是，当进行另一项测试时，我得到以下信息:
setUp method in parent runs each time before the test, than setUp method in the child starts to run, which successfully opens a browser and completes the test. However, when it goes to another test, I get the following:
invalid session id

推荐答案
所以问题在于页面对象是以Singleton方式设计的:
So the issue is that the page objects are designed in Singleton way:
public static LoginModal loginModalInstance(WebDriver driver) {
return loginModal == null ? loginModal = new LoginModal(driver) : loginModal;
}
因此，在第一次测试中使用驱动程序进行初始化后，它们在新测试中仍将引用旧的驱动程序实例(已关闭).
So that once initialized with a driver in first test they remain refering to old driver instance (which has been already closed) in new test.
解决方案是重新加工loginModalInstance和其他类似方法，以便它们使用新的驱动程序实例重新初始化现有对象的字段.
The solution would be to rework loginModalInstance and other similar methods so that they re-initialize the fields of existing objects with new driver instance.
