我确实有一个页面对象和用于sign_in功能的测试类，同时将该测试sign_in方法调用到另一个测试类中时，它显示nullpointerexception，该登录必须重用其必须登录的其他功能才能进入其他功能
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();

我在另一个测试类中提到了相同的登录方法，所以我在不同的类中都提到了相同的登录方法，任何帮助我如何调用登录方法来代替编写不同功能类的长度代码的方法
答案 0 :(得分：0)
在检查了您的代码之后，我有两种方法来处理这种情况： 1）在BaseClass的@BeforeTest中包括“ VerifySigninpage”方法代码。默认情况下，可以在实际测试开始之前进行登录功能，并执行特定的主页/任何其他页面测试，而无需依赖登录 2）在单独的类中将SignIn方法编写为实例方法，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();

我猜您正在传入一个无效的浏览器参数，该参数不是小写字母，或者不等于chrome，firefox或ie。如果未设置/无法匹配传入的浏览器参数，则我将代码默认设置为Firefox，并且我还强制将传入的参数设置为小写字母，以处理由于诸如此类的输入而导致的潜在错误Firefox：
@Parameters("browser")
@BeforeClass
public void baseSetup(String browser) {
//I assigned the logger here since it wasn't being done, you may not want to do this
logger = Logger.getLogger("Payroll");
PropertyConfigurator.configure("log4j.properties");
switch (browser.toLowerCase()) {
case "chrome": {
//Setting a property like this is generally bad practice, you may be overwriting a property that has already been set on a build agent
System.setProperty("webdriver.chrome.driver", readconfig.getChromePath());
driver = new ChromeDriver();
break;
}
case "ie": {
//Setting a property like this is generally bad practice, you may be overwriting a property that has already been set on a build agent
System.setProperty("webdriver.chrome.driver", readconfig.getIEPath());
driver = new InternetExplorerDriver();
break;
}
case "firefox": {
//Setting a property like this is generally bad practice, you may be overwriting a property that has already been set on a build agent
System.setProperty("webdriver.gecko.driver", readconfig.getFirefoxPath());
driver = new FirefoxDriver();
break;
}
default: {
//Set a default of firefox, you can change this to whatever you want.
logger.info(String.format("Unable to resolve %s, defaulting to `firefox`...", browser));
//Setting a property like this is generally bad practice, you may be overwriting a property that has already been set on a build agent
System.setProperty("webdriver.gecko.driver", readconfig.getFirefoxPath());
driver = new FirefoxDriver();
}
}
driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS);
//Don't use implicit waits, use explicit waits instead. Any checks to make sure a element does not exist will take 50 seconds
driver.manage().timeouts().implicitlyWait(50, TimeUnit.SECONDS);
driver.get(baseurl);
driver.manage().window().maximize();
driver.manage().deleteAllCookies();
}
@AfterClass
public void tearDown() {
//Don't use driver.close() for cleanup!
//It will throw an additional exception if the browser window has already been closed due to error
driver.quit();
}
我已添加内联注释，以解释所做的更改并指出我可以看到的明显问题。希望这可以使您启动并运行，并注销作为参数browser传入的值，以便您查看所发送的值是否不是预期值之一。
