Java 如何将功能对象传递给TestNG ITestlistener（或在类中引用ITestlistener方法）？

我们目前正在使用硒、TestNG和Saucelabs。我试图覆盖

onTestSuccess

和

onTestFailure

侦听器方法，以便根据方法的结果将功能设置为

true/false

我试过几种方法都没有成功。简要总结：

MainSauceLabsClass.java

public class MainSauceLabsClass {
    // .....
    public static DesiredCapablities desiredCapabilities;
    // ....
    @BeforeMethod 
    //set a whole range of parameters for Saucelabs here,e.g.:
    desiredCapabilities = DesiredCapabilities.iphone();
    desiredCapabilities.setCapabilities("idleTimeout",300);
    // etc...
}

public class CustomTestListener implements ITestListener {
    // ...
    @Override
    public void onTestSuccess(ITestResult result) {
        // I want to pass to saucelabs pass/fail result via "passed" capability. something like 
        // desiredCapabilities.setCapabilities("passed",true);
    }
}

@Listeners(CustomTestListener.class)
public class MainSauceLabsClass {
    public static final ThreadLocal<DesiredCapabilities> CURRENT_DESIRED_CAPABILITIES =
            new InheritableThreadLocal<>();

    @BeforeMethod
    public void setDesiredCapabilities() {
        DesiredCapabilities desiredCapabilities = DesiredCapabilities.iphone();
        desiredCapabilities.setCapability("idleTimeout", 300);
        CURRENT_DESIRED_CAPABILITIES.set(desiredCapabilities);
    }
}

public class CustomTestListener implements ITestListener {
    // ...
    @Override
    public void onTestSuccess(ITestResult result) {
        DesiredCapabilities desiredCapabilities =
                MainSauceLabsClass.CURRENT_DESIRED_CAPABILITIES.get();
        desiredCapabilities.setCapability("passed", true);
    }
}

CustomTestListener.java

public class MainSauceLabsClass {
    // .....
    public static DesiredCapablities desiredCapabilities;
    // ....
    @BeforeMethod 
    //set a whole range of parameters for Saucelabs here,e.g.:
    desiredCapabilities = DesiredCapabilities.iphone();
    desiredCapabilities.setCapabilities("idleTimeout",300);
    // etc...
}

public class CustomTestListener implements ITestListener {
    // ...
    @Override
    public void onTestSuccess(ITestResult result) {
        // I want to pass to saucelabs pass/fail result via "passed" capability. something like 
        // desiredCapabilities.setCapabilities("passed",true);
    }
}

@Listeners(CustomTestListener.class)
public class MainSauceLabsClass {
    public static final ThreadLocal<DesiredCapabilities> CURRENT_DESIRED_CAPABILITIES =
            new InheritableThreadLocal<>();

    @BeforeMethod
    public void setDesiredCapabilities() {
        DesiredCapabilities desiredCapabilities = DesiredCapabilities.iphone();
        desiredCapabilities.setCapability("idleTimeout", 300);
        CURRENT_DESIRED_CAPABILITIES.set(desiredCapabilities);
    }
}

public class CustomTestListener implements ITestListener {
    // ...
    @Override
    public void onTestSuccess(ITestResult result) {
        DesiredCapabilities desiredCapabilities =
                MainSauceLabsClass.CURRENT_DESIRED_CAPABILITIES.get();
        desiredCapabilities.setCapability("passed", true);
    }
}

显然，问题是我无法在

CustomTestListener.java

中引用对象

desiredCapabilities

，因为它是在

MainSauceLabsClass

中设置的。我的问题是，实施这一计划的最佳方式是什么。要么：

• 在

  CustomTestListener

  中以某种方式引用相同的

  desiredCapabilities

  对象来调用

  setCapabilities

  方法
• 在

  MainSauceLabsClass

  中访问

  onTestSuccess

  ，并在

  @AfterMethod

  中设置它，以便可以在同一类中引用

  所需的功能

• 替代方案

如有需要，乐意提供更多信息。感谢您的帮助

显然，问题是我无法在

CustomTestListener.java

中引用对象

desiredCapabilities

，因为它是在

MainSauceLabsClass

中设置的

由于您的

desiredCapabilities

是一个

公共静态

变量，因此您可以从

CustomTestListener

中“引用”它。e、 g:

public class CustomTestListener implements ITestListener {
    // ...
    @Override
    public void onTestSuccess(ITestResult result) {
        MainSauceLabsClass.desiredCapabilities.setCapabilities("passed",true);
    }
}

但是，如果在

MainSauceLabsClass

中的

@before方法

之前调用

CustomTestListener.onTestSuccess（ITestResult）

，则您将得到一个

NullPointerException

（这可能就是您所说的“无法引用……因为它是在

MainSauceLabsClass

中设置的”）

如果您正在尝试存储与每个测试相关联的数据，那么您可以在每个测试及其配置（before/after）方法在各自的线程中运行时使用。然后可以设置并获取当前测试的值。e、 g:

MainSauceLabsClass.java

public class MainSauceLabsClass {
    // .....
    public static DesiredCapablities desiredCapabilities;
    // ....
    @BeforeMethod 
    //set a whole range of parameters for Saucelabs here,e.g.:
    desiredCapabilities = DesiredCapabilities.iphone();
    desiredCapabilities.setCapabilities("idleTimeout",300);
    // etc...
}

public class CustomTestListener implements ITestListener {
    // ...
    @Override
    public void onTestSuccess(ITestResult result) {
        // I want to pass to saucelabs pass/fail result via "passed" capability. something like 
        // desiredCapabilities.setCapabilities("passed",true);
    }
}

@Listeners(CustomTestListener.class)
public class MainSauceLabsClass {
    public static final ThreadLocal<DesiredCapabilities> CURRENT_DESIRED_CAPABILITIES =
            new InheritableThreadLocal<>();

    @BeforeMethod
    public void setDesiredCapabilities() {
        DesiredCapabilities desiredCapabilities = DesiredCapabilities.iphone();
        desiredCapabilities.setCapability("idleTimeout", 300);
        CURRENT_DESIRED_CAPABILITIES.set(desiredCapabilities);
    }
}

public class CustomTestListener implements ITestListener {
    // ...
    @Override
    public void onTestSuccess(ITestResult result) {
        DesiredCapabilities desiredCapabilities =
                MainSauceLabsClass.CURRENT_DESIRED_CAPABILITIES.get();
        desiredCapabilities.setCapability("passed", true);
    }
}

您已将DesiredCapabilities对象声明为public和static。那么，是什么阻止您使用该对象，如“MainSauceLabsClass.DesiredCapabilities”？在listener类内部
