我正在使用 winium 和 TestNg 测试 Excel 文件。当我手动启动winium驱动程序时，测试用例工作正常。当我尝试从 java 启动 Winium 服务时，启动 Winium 驱动程序给我带来了问题。代码如下：

package testcases;
import java.io.*;
import java.nio.file.Paths;
import java.text.*;
import java.util.*;
import org.openqa.selenium.winium.WiniumDriverService;
import org.testng.*;
import org.testng.collections.Lists;
import HelperClass.ExcelFiles;

public class WiniumRunner {

private static final DateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss");

public static void main(String[] args) throws InterruptedException, IOException {
    File file = new File(Paths.get(".").toAbsolutePath().normalize().toString());
    String winiumDriverPath = file + "\\Winium.Desktop.Driver\\Winium.Desktop.Driver.exe";

    System.out.println("Starting service of Winium Desktop Driver");
    WiniumDriverService service = new WiniumDriverService.Builder().usingDriverExecutable(new
            File(winiumDriverPath)).usingPort(9999).withVerbose(true).withSilent(false).buildDesktopService();

    service.start(); // Build and Start a Winium Driver service
    Thread.sleep(5000);
    System.out.println("Started service of Winium Desktop Driver");

    String cDateTime = "";
    Date date = new Date();      
    cDateTime = cDateTime + (sdf.format(date));   
    cDateTime = file+"\\Reports\\Mockito_Test_Reports\\";

    ExcelFiles EF= new ExcelFiles();
    EF.createExcelFile();
    TestListenerAdapter tla = new TestListenerAdapter();
    TestNG testng = new TestNG();
    testng.setOutputDirectory(cDateTime);

    List<String> suites = Lists.newArrayList();
    System.out.println("**********Test Report Location   :"+file+"\\src\\props\\testng2.xml");
    suites.add(file+"\\src\\test\\java\\testcases\\testng2.xml");
    testng.setTestSuites(suites);
    testng.addListener(tla);
    testng.run();

    Process process = Runtime.getRuntime().exec("taskkill /F /IM Winium.Desktop.Driver.exe");
    process.waitFor();
    process.destroy();
}
}

我低于异常：

我无法调试错误。如果有人可以建议更改代码。

提前致谢。

您看到异常的原因

org.openqa.selenium.WebDriverException: Value cannot be null.
    Parameter name: executableFilePath

是因为在Application构造函数executableFilePath中为 null 。结果没有设置：DesiredCapabilities

{
  "desiredCapabilities": {
    "app": null
  }
}

根据自述文件，您应该DesktopOptions在创建WebDriver类的实例之前设置：

DesktopOptions options = new DesktopOptions();
options.setApplicationPath("pathToWindowsApplication");
options.setDebugConnectToRunningApp(true);
WiniumDriverService service = new WiniumDriverService.Builder().usingDriverExecutable(new File(winiumDriverPath)).usingPort(9999).withVerbose(true).withSilent(false).buildDesktopService();
WiniumDriver driver = new WiniumDriver(service, options);
service.start(); // Build and Start a Winium Driver service
