运行 SoapUI 后，无法启动 selenium

Question

我有问题。 我通过 Java 自动化代码运行 SoapUI Web 服务测试。 但在那之后。 硒不起作用。 似乎soapUI 部分实际上没有完成。 但我不确定。

public static void main(String[] args) throws Exception {
    SoapUIRun srun = new SoapUIRun();
    srun.runTestCase("CPIHS", "CPIHS");
    new MainPage().LoginCad();
}

异常消息是：

但是，我注释掉了 SoapUI 部分。 它会再次起作用。 喜欢：

public static void main(String[] args) throws Exception {
    //SoapUIRun srun = new SoapUIRun();
    //srun.runTestCase("CPIHS", "CPIHS");
    new MainPage().LoginCad();
}

这是我的 SoapUI 方法：

public void runTestCase(String tarSuite, String tarCase) throws Exception {

    String reportStr = "";

    TestRunner runner;

    SoapUI.setSoapUICore(new StandaloneSoapUICore(true));

    WsdlProject project = new WsdlProject("C:\\Users\\tshi\\Documents\\Maven Projects\\ASORT\\WebServiceResource\\Suncorp_Issuing-soapui-project.xml");

    List<TestSuite> suiteList = project.getTestSuiteList();

    for (TestSuite aSuiteList : suiteList) {

        String suiteName = aSuiteList.getName();

        List<TestCase> caseList = aSuiteList.getTestCaseList();
        //System.out.println("Test Suite: " + suiteName);

        if (suiteName.equals(tarSuite)) {

            for (TestCase aCaseList : caseList) {

                String caseName = aCaseList.getName();
                //System.out.println("Test Case: " + caseName);

                if (caseName.equals(tarCase)) {

                    long startTime = System.currentTimeMillis();

                    runner = project.getTestSuiteByName(suiteName).getTestCaseByName(caseName).run(new PropertiesMap(), false);

                    long duration = System.currentTimeMillis() - startTime;

                    reportStr = reportStr + "\n\tTestCase: " + aCaseList.getName() + "\tStatus: " + runner.getStatus() + "\tReason: " + runner.getReason() + "\tDuration: " + duration;

                    System.out.print(reportStr);

                }

            }

        }

    }

}

这是与硒相关的方法：

public void LoginCad(){
    System.setProperty("webdriver.chrome.bin", "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");
    System.setProperty("webdriver.chrome.driver","C:\\Program Files (x86)\\Google\\Chrome\\Application\\chromedriver.exe");

    String bank = Integer.toString(48);
    String emp = Integer.toString(200003);
    String pwd = "Cadencie1";
    String baseUrl = "http://172.16.1.133:8090/AppName/servlet/app";

    driver = new ChromeDriver();

    driver.get(baseUrl);

    try {

        Thread.sleep(1000);

    } catch(InterruptedException e){

        // TO DO Auto-generated catch block
        e.printStackTrace();

    }

    Utilities.switchToWindow("AppName - User Logon [LOGON]", driver);

    try{

        Thread.sleep(2000);

    } catch(InterruptedException e){

        // TO DO Auto-generated catch block
        e.printStackTrace();

    }

    driver.findElement(By.id("idBANK")).clear();
    driver.findElement(By.id("idBANK")).sendKeys(bank);

    driver.findElement(By.id("idEMPLOYEE")).clear();
    driver.findElement(By.id("idEMPLOYEE")).sendKeys(emp);

    driver.findElement(By.id("idPASSWORD")).clear();
    driver.findElement(By.id("idPASSWORD")).sendKeys(pwd);

    driver.findElement(By.id("maintLOGON")).click();

    driver.findElement(By.id("idPASSWORD")).clear();
    driver.findElement(By.id("idPASSWORD")).sendKeys(pwd);

    driver.findElement(By.id("maint")).click();

}

任何人都知道为什么会发生这种情况。 我在谷歌上搜索过。 但似乎没有人在同样的情况下犯同样的错误。 非常感谢。

Answer 1

如果问题仅在SOAPUI执行后出现在selenium 上，那么可能是某些SOAPUI配置导致了该问题。 该问题可能是由于SOAPUI将默认代理设置为null ，然后当selenium尝试获取代理以检查配置时收到NullPointerExcetpion 。

根据您的错误跟踪：

Caused by: java.lang.NullPointerException 
at org.apache.http.impl.conn.SystemDefaultRoutePlanner.determineProxy(SystemDefaultRoutePlanner.java:79) 

如果你看一下org.apache.http.impl.conn.SystemDefaultRoutePlanner类的源代码：

（注意我保留行号以与您的错误跟踪相关联）

53 public class More ...SystemDefaultRoutePlanner extends DefaultRoutePlanner {
54 
55     private final ProxySelector proxySelector;
56 
57     public More ...SystemDefaultRoutePlanner(
58             final SchemePortResolver schemePortResolver,
59             final ProxySelector proxySelector) {
60         super(schemePortResolver);
         /*
           proxySelector ARE NULL AND ProxySelector.getDefault(); 
           RETURNS ALSO NULL DUE THAT SOAPUI PROBABLY MAKE BEFORE
           ProxySelect.setDefault(null);
         */
61         this.proxySelector = proxySelector != null ? proxySelector : ProxySelector.getDefault();
62     }
63 
64     public More ...SystemDefaultRoutePlanner(final ProxySelector proxySelector) {
65         this(null, proxySelector);
66     }
67 
68     @Override
69     protected HttpHost More ...determineProxy(
70             final HttpHost    target,
71             final HttpRequest request,
72             final HttpContext context) throws HttpException {
73         final URI targetURI;
74         try {
75             targetURI = new URI(target.toURI());
76         } catch (final URISyntaxException ex) {
77             throw new HttpException("Cannot convert host to URI: " + target, ex);
78         }
           /* HERE IS THE NULLPOINTER */
79         final List<Proxy> proxies = this.proxySelector.select(targetURI);

解决方法

所以一个可能的解决方案是自己处理ProxySelect 。 然后您可以尝试使用以下解决方法：

import java.net.ProxySelector;
...

public static void main(String[] args) throws Exception {

    // get default proxy before soapui will set it to null
    ProxySelector proxy = ProxySelector.getDefault();

    SoapUIRun srun = new SoapUIRun();
    srun.runTestCase("CPIHS", "CPIHS");

    // set it again to avoid NPE on selenium
    ProxySelector.setDefault(proxy);

    new MainPage().LoginCad();
}

Answer 2

谢谢@albciff 提供的解决方法，但对我来说没有帮助。 我终于创建了新的代理：

report.step("Verify 'proxySelector' not NULL");
ProxySelector proxy = ProxySelector.getDefault();
if (proxy == null) {
    //Creating new Proxy
    ProxySelector proxySelector = new ProxySelector() {
        @Override
        public List<Proxy> select(URI uri) {
            return new ArrayList<Proxy>(){{
                add(Proxy.NO_PROXY);
            }};
        }

        @Override
        public void connectFailed(URI uri, SocketAddress sa, IOException ioe) {
        }
    };

    report.report("Set new proxySelector (Proxy.NO_PROXY)", Reporter.WARNING);
    ProxySelector.setDefault(proxySelector);

}else{
    report.report("Proxy is not NULL continue..");
}
