java - 无法使用页面工厂从 selenium 中的另一个测试类调用测试方法

Question

我确实有一个用于sign_in功能的页面对象和测试类，当将该测试sign_in方法调用到另一个测试类时，它显示空指针异常，该登录必须重用不同的功能，必须登录才能进入另一个功能.

        public class VerifySignIn extends BaseClass{
        public SignIn sign;
        public String expectedSignpage = "Checkmark Canada Cloud Payroll | 
        Dashboard";

        @Test(priority=1)
        public void VerifySigninpage() {
        try {
        test = report.startTest("Verify Signin Test");
        test.log(LogStatus.INFO, "Test Started" + test.getStartedTime());
        sign = PageFactory.initElements(driver, SignIn.class);
        sign.enterEmailID(userid);
        sign.enterPassword(pwd);
        sign.clickSigninBtn();
        String dashboardTitle = driver.getTitle();
        Assert.assertEquals(expectedSignpage, dashboardTitle);
        System.out.println("the title after signin is: "+dashboardTitle);
        } catch (Exception e) {
        System.out.println("Test signin not executed msg is: " + 
        e.getMessage());
        }
        }
        }

i have called that signin method in this class it show `NullPointerException` COULD ANYONE HELP ME,how to call `@test` method of one class into another `@test` method of another class.how to write sign-in functionality using `PageFactory` so it can reuse for different functionality.


public class VerifyAddOtherDeductions extends BaseClass {
public SignIn sign;
public AddOtherDeductions deductions;
String expectedtitle="Checkmark Canada Cloud Payroll | Deductions";

@Test(priority=1)
  public void verifySignIn() {
    try {
        test = report.startTest("Verify to signin Test");
        test.log(LogStatus.INFO, "Test Started" + test.getStartedTime());
        sign=PageFactory.initElements(driver, SignIn.class);
        sign.enterEmailID(userid);
        sign.enterPassword(pwd);
        sign.clickSigninBtn();
        String dashboardTitle = driver.getTitle();
        System.out.println("After signin page title is: "+dashboardTitle);
    } catch (Exception e) {
System.out.println("verify signin exception is: "+e.getMessage());
    }

}

@Test(priority=2)
public void verifyOtherDeductionsAddFromList() {
    test = report.startTest("Verify OtherDeductions Add From List Test");
    test.log(LogStatus.INFO, "Test Started" + test.getStartedTime());
    deductions=PageFactory.initElements(driver, AddOtherDeductions.class);
    deductions.companySetupClick();
    deductions.clickOtherDeductions();
    Assert.assertEquals(driver.getTitle(), expectedtitle);
    deductions.addFromListBtn();
    deductions.selectFromList();
    deductions.addList();
    deductions.confirmbtnclick();
    }

我在另一个测试类中提到了相同的登录方法，所以我提到了不同类的相同登录方法，任何帮助我如何调用登录方法而不是为不同的功能类编写冗长的代码

Answer 1

查看您的代码后，我有两种方法来处理这种情况:1) 在BaseClass的@BeforeTest中包含'VerifySigninpage'方法代码。默认情况下，可以在实际测试开始之前处理登录功能并执行特定主页/任何其他页面测试，而无需依赖 SignIn2) 在单独的类中编写 SignIn 方法作为实例方法，并通过为 LoginFunctionality 类创建对象来在 @Test 方法中调用 SignIn 方法

VerifySignIn page = new VerifySignIn();
page.SignIn();
