我的Java如何解決在硒的webdriver空指針異常與Java
public class LaunchApplication {
private String LAUNCHAPPLICATION_STATUS=null;
private String LAUNCHAPPLICATION_MESSAGE=null;
@Test
@Parameters({"RUN_USING_SG","BROWSER_CODE","URL","TITLE","PLATFORM","VERSION"})
public void LAUNCHAPPLICATION(String RunUsingSG,String BrowserCode,String URL,String Title,String Platform,String Version) throws MalformedURLException
{
try
{
System.out.println(System.getProperty("user.dir"));
DesiredCapabilities dc=new DesiredCapabilities();
if(BrowserCode.equalsIgnoreCase("IE32"))
{
System.setProperty("webdriver.ie.driver",System.getProperty("user.dir")+"/AllDrivers/IEDriverServer_32bit_OS.exe");
dc.setBrowserName("internet explorer");
dc.setVersion(Version);
Config.driver = new InternetExplorerDriver();
}
if(BrowserCode.equalsIgnoreCase("IE64"))
{
System.setProperty("webdriver.ie.driver",System.getProperty("user.dir")+"/AllDrivers/IEDriverServer_64bit_OS.exe");
dc.setBrowserName("internet explorer");
dc.setVersion(Version);
Config.driver = new InternetExplorerDriver();
}
if(BrowserCode.equalsIgnoreCase("FF"))
{
FirefoxProfile firefoxProfile = new FirefoxProfile();
dc.setBrowserName("firefox");
dc.setVersion(Version);
Config.driver=new FirefoxDriver();
}
if(RunUsingSG.equalsIgnoreCase("Y"))
{
Config.driver=new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),dc);
}
if(Platform.equalsIgnoreCase("WINDOWS"))
{dc.setPlatform(org.openqa.selenium.Platform.WINDOWS);}
Config.driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
Config.driver.get(URL);
Config.driver.manage().window().maximize();
//perform final validation
if(Config.driver.getTitle().toLowerCase().equalsIgnoreCase(Title))
{
LAUNCHAPPLICATION_STATUS="PASS";
LAUNCHAPPLICATION_MESSAGE="EXPECTED BROWSER TITLE:"+Title+", ACTUAL BROWSER TITLE :"+Config.driver.getTitle()+", FOR THE URL:"+URL;
}
}//end of try
catch(Exception generalException)
{
LAUNCHAPPLICATION_STATUS="FAIL";
LAUNCHAPPLICATION_MESSAGE= "EXPECTED BROWSER TITLE:"+Title+", ACTUAL BROWSER TITLE :"+Config.driver.getTitle()+", FOR THE URL:"+URL+". DETAILS:Exception Occoured:"+generalException.getLocalizedMessage();
}
}
//@BeforeTest
//public void f1(ITestContext ctx) {
// if(ctx.getCurrentXmlTest().getParameter("EXECUTE").equals("NO"))
// {
// throw new SkipException("skiping this test case");
//}
}
我通過testng.I執行不知道爲什麼，當獲得空指針異常的錯誤在上面的代碼？當我經過的JUnit執行它工作正常？因此，任何幫助？我想，這可能發生，因爲我已經宣佈LAUNCHAPPLICATION_STATUS = NULL;或任何其他問題。在TestNGContentHandler.endElement()這是一個非常強大的暗示，這個問題是在XML文件中，而不是你LaunchApplication類中發生
