java - 如何在selenium服务器上提供自定义功能？

Question

我知道可以通过某种方法获得一些 Selenium 功能，其中之一如下:

driver.getCapability().getBrowserName();

它返回浏览器名称的值。

但是如果它指的是一个可用的方法，如果我没有误解的话，这似乎与自定义功能有关，就像我的意思一样:

driver.getCapability().getCapability("某事？");

返回:值，如果未设置则返回 null。

因此，我尝试编写一个简单的代码来获取我想要的值。

    private RemoteWebDriver driver;
    private URL url;
    private DesiredCapabilities dc = new DesiredCapabilities();

    @Before
    public void setUp() throws MalformedURLException {
        url = new URL("http://localhost:4444/wd/hub");
        dc.setCapability(CapabilityType.BROWSER_NAME, BrowserType.CHROME);
        //this is custom capability i mean
        dc.setCapability("testName", "Login");
        driver = new RemoteWebDriver(url, dc);
    }
    
    @Test
    public void test() {
        some code.....
    }
    
    @After
    public void tearDown() {
        System.out.println("Browser Name : "+ driver.getCapabilities().getCapability("browserName"));
        System.out.println("Test Name : "+ driver.getCapabilities().getCapability("testName"));
        driver.quit();
    }

使用 json，服务器日志显示:

Capabilities are: {
  "browserName": "chrome",
  "testName": "Login"
}

但是我得到了一个null值。

如何正确设置？如何让我们的服务器提供我的意思是 testName 的功能？可以通过 driver.getCapability().getCapability("testName");

获取

当前结果 浏览器名称:chrome 测试名称:null

预期结果 浏览器名称:chrome 测试名称:登录

您可以提取WebDriver 功能，例如使用以下任一解决方案的浏览器名称、浏览器版本、平台名称等:

• 使用直接 API:

  • 代码块:

    System.out.println("Class Name is : "+((RemoteWebDriver) driver).getCapabilities().getClass().toString());
    System.out.println("Browser Name is : "+((RemoteWebDriver) driver).getCapabilities().getBrowserName().toLowerCase());
    System.out.println("Browser Version is : "+((RemoteWebDriver) driver).getCapabilities().getVersion().toString());
    System.out.println("Platform Name is : "+((RemoteWebDriver) driver).getCapabilities().getPlatform().toString());
    

  • 控制台输出:

    Class Name is : class org.openqa.selenium.MutableCapabilities
    Browser Name is : firefox
    Browser Version is : 67.0
    Platform Name is : WINDOWS
    

• 使用getCapability():

  • 代码块:

    Capabilities cap = ((RemoteWebDriver) driver).getCapabilities();
    System.out.println("acceptInsecureCerts value is: "+cap.getCapability("acceptInsecureCerts"));
    System.out.println("Browser Name is : "+cap.getBrowserName());
    System.out.println("Browser version is : "+cap.getVersion());           
    System.out.println("Platform is : "+cap.getPlatform().toString());
    System.out.println("javascriptEnabled value is: "+cap.getCapability("javascriptEnabled"));
    System.out.println("moz:accessibilityChecks value is: "+cap.getCapability("moz:accessibilityChecks"));
    System.out.println("moz:buildID value is: "+cap.getCapability("moz:buildID"));
    System.out.println("geckodriverVersion value is: "+cap.getCapability("geckodriverVersion"));
    System.out.println("Headless Mozilla value is: "+((RemoteWebDriver) driver).getCapabilities().getCapability("moz:headless"));
    System.out.println("moz:headless value is: "+cap.getCapability("moz:headless"));
    System.out.println("Mozilla Profile value is : "+ ((RemoteWebDriver) driver).getCapabilities().getCapability("moz:profile"));
    System.out.println("moz:processID value is : "+cap.getCapability("moz:processID"));
    System.out.println("moz:profile value is : "+cap.getCapability("moz:profile"));
    System.out.println("moz:shutdownTimeout value is : "+cap.getCapability("moz:shutdownTimeout"));
    System.out.println("moz:useNonSpecCompliantPointerOrigin value is : "+cap.getCapability("moz:useNonSpecCompliantPointerOrigin"));
    System.out.println("moz:webdriverClick value is : "+cap.getCapability("moz:webdriverClick"));
    System.out.println("pageLoadStrategy value is : "+cap.getCapability("pageLoadStrategy"));
    System.out.println("Platform is : "+cap.getPlatform().toString());
    System.out.println("platformName value is : "+cap.getCapability("platformName"));
    System.out.println("platformVersion value is : "+cap.getCapability("platformVersion"));
    System.out.println("rotatable value is : "+cap.getCapability("rotatable"));
    System.out.println("setWindowRect value is : "+cap.getCapability("setWindowRect"));
    System.out.println("strictFileInteractability value is : "+cap.getCapability("strictFileInteractability"));
    System.out.println("timeouts values are : "+cap.getCapability("timeouts"));
    System.out.println("unhandledPromptBehavior value is : "+cap.getCapability("unhandledPromptBehavior"));
    

  • 控制台输出:

    acceptInsecureCerts value is: true
    Browser Name is : firefox
    Browser version is : 67.0
    Platform is : WINDOWS
    javascriptEnabled value is: true
    moz:accessibilityChecks value is: false
    moz:buildID value is: 20190516215225
    geckodriverVersion value is: null
    Headless Mozilla value is: false
    moz:headless value is: false
    Mozilla Profile value is : C:\Users\Debanjan.B\AppData\Local\Temp\rust_mozprofile.7HI7QUtzF1YP
    moz:processID value is : 7308
    moz:profile value is : C:\Users\Debanjan.B\AppData\Local\Temp\rust_mozprofile.7HI7QUtzF1YP
    moz:shutdownTimeout value is : 60000
    moz:useNonSpecCompliantPointerOrigin value is : false
    moz:webdriverClick value is : true
    pageLoadStrategy value is : normal
    Platform is : WINDOWS
    platformName value is : WINDOWS
    platformVersion value is : 6.2
    rotatable value is : false
    setWindowRect value is : true
    strictFileInteractability value is : false
    timeouts values are : {implicit=0, pageLoad=300000, script=30000}
    unhandledPromptBehavior value is : dismiss and notify
