我在Testng中调用方法时得到NullPointerexeption
我试过调试，问题出在我的CommonLib.selectlist方法上，因为一切都很好，请检查并提供解决方案
我正在运行testcase.java
testcase脚本
public class Testcase extends beforeexecution.Login1 {
public static Xls_Reader exel1;
@BeforeClass
public void login() throws IOException, Throwable{
Login1 x = new Login1();
x.Readproperties();
exel1 = new Xls_Reader(Login1.props.getProperty("TestDataPath"));
String siteurl = exel1.getCellData("Login", "TestUrl", 2);
String acc = exel1.getCellData("Login", "Account", 2);
String passw=exel1.getCellData("Login", "Password", 2);
Login1.getDriver();
driver.get(siteurl);
/*driver.manage().window().maximize();*/
Login1.logintoapp(acc, passw);
Thread.sleep(5000);
}
@Test
public void Executemain() throws InterruptedException{
String studyname = exel1.getCellData("Login", "Studyname", 2);
CommonLib.selectlist(studyname);
String datasheetname=exel1.getCellData("Login", "Form", 2);
CommonLib.action(datasheetname);
}
}
CommonLib脚本
public class CommonLib extends Login1 {
public static WebDriver driver;
static ChromeOptions options;
public static void main(String [] arg){
}
public static void selectlist(String studyname) throws
InterruptedException{
WebElement studyxpath =
driver.findElement(By.xpath("//select[@id='studyList']"));
System.out.println(studyxpath);
Select dropdown = new Select(studyxpath);
dropdown.selectByVisibleText(studyname);
}
我的login1脚本
public class Login1 {
public static Properties props;
public static WebDriver driver;
public static void main(String [] arg){
}
public void Readproperties() throws IOException {
InputStream propertiesFilePath =
Login1.class.getClassLoader().getResourceAsStream
("Filepath/Config.properties");
props = new Properties();
props.load(propertiesFilePath);
}
public static WebDriver getDriver(){
System.setProperty("webdriver.chrome.driver",
"C:\\Users\\aroy\\Desktop\\Sele\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
return driver;
}
public static void logintoapp(String acc, String passw) throws
InterruptedException{
driver.findElement(By.xpath("//input[@id='userName']")).sendKeys(acc);
driver.findElement(By.xpath("//input[@id='password']")).sendKeys(passw);
driver.findElement(By.xpath("//button[@id='loginBtn']")).click();
System.out.println("Login SuccessFully");
Thread.sleep(5000);
}
}

请检查并提供解决方案，因为我的框架工作因此操作而停止
