我有一个登录页面，其中包含用户名和密码。我有一个XcelParserTestNGLogin类，用于创建，更新和从Excel工作表方法加载。另一个类Login是TestNG类。我正在使用DataProvider从Excel传递数据。但是我遇到异常数据提供者试图传递4个参数，但是该方法需要2个。
这是我的TestNG代码：
public class Login {
private static WebDriver driver;
XcelParserTestNGLogin login1 = new XcelParserTestNGLogin();
Object[][] data1;
/*public Login() throws IOException, InterruptedException {
FileInputStream fis = new FileInputStream("Data//LoginPage.xls");
XcelParserTestNGLogin login1 = new XcelParserTestNGLogin(fis, "Login");
//this.data1 = login1.loadFromSpreadsheet(fis, "Login");
}*/
@BeforeClass
public void test() throws Exception {
System.setProperty("webdriver.chrome.driver",
"C:\\Chrome\\chromedriver_win_26.0.1383.0\\chromedriver.exe");
driver = new ChromeDriver();
driver.get("Any Url");
}
@DataProvider
public Object[][] dp() throws IOException {
//login1.fileName = "Data//Login.xls";
//login1.sheetName = "Sheet1";
FileInputStream fis = new FileInputStream("Data//LoginPage.xls");
String sheetName = "Login";
login1.loadFromSpreadsheet(fis,sheetName);
return login1.getData();
}
@Test(dataProvider = "dp")
public void devLogin(String UserName,String PassWord) throws InterruptedException, IOException {
driver.findElement(By.name("txtUserName")).sendKeys(UserName);
driver.findElement(By.name("txtPwd")).sendKeys(PassWord);
driver.findElement(By.name("btnSignIn")).click();
Thread.sleep(5000);
if (driver.findElement(By.linkText("DashBoard")).isDisplayed()) {
List<String> arrayList = new ArrayList<String>();
arrayList.add("Pass");
HSSFWorkbook workbook = new HSSFWorkbook();
login1.createSheet("Login", workbook, arrayList);
}
else {
try{
Alert alert=driver.switchTo().alert();
String alertText=alert.getText();
Assert.assertEquals("invalid username or password,please try again",alertText);
alert.accept();
}catch(UnhandledAlertException e){
e.printStackTrace();
}
List<String> arrayList = new ArrayList<String>();
arrayList.add("Fail");
HSSFWorkbook workbook = new HSSFWorkbook();
login1.createSheet("Login", workbook, arrayList);
}
}
}

最佳答案
请记住，对象数组左边第一个方括号的长度指示将调用您的测试方法的次数。
第二个方括号的长度表示您的测试方法应包含多少个参数。根据测试方法的签名，数组声明应为obj = new Object[maxRows][2]。
