android - 通过下一个测试用例的 appium java 脚本重新打开应用程序

Question

我成功运行了 appium java 脚本。但问题是，我的应用程序从登录页面开始。登录后，我可以自动化一些测试用例。但我想通过脚本从登录页面再次运行以运行下一个测试用例..如何关闭应用程序以及从后台模式重新打开应用程序而无需再次重新安装应用程序？因为测试用例不应该相互依赖

public class AppTest {

    private static RemoteWebDriver driver;

    @BeforeClass
    public static void initSimulator() throws MalformedURLException
    {
            DesiredCapabilities capabilities = new DesiredCapabilities();

            capabilities.setCapability("platformName", "Android");            
            capabilities.setCapability("platformVersion", "5.0.1");           
            capabilities.setCapability("deviceName", "emulator-5554");                
            capabilities.setCapability("app", "D:\\adt-bundle-windows-x86_64-20140702\\sdk\\platform-tools\\Yr.apk");    
            capabilities.setCapability("app-package", "com.you.android");                   
            capabilities.setCapability("app-activity", "com.yr.sts.SplashActivity");                  
            capabilities.setCapability("app_wait_activity",".MainActivity");

            driver = new RemoteWebDriver(new URL("http://127.0.0.1:4723/wd/hub"),
                capabilities);

            System.out.println("App Launched");
    }
    @AfterClass
    public static void quitDriver() 
    {
       driver.quit();
       System.out.println("Driver has been Quit");
    }

    @Test
    public void sign_in_Click() throws InterruptedException 
    {
        WebElement sign_button = driver.findElement(By.name("Sign-in"));
        sign_button.click();
        WebElement usr = driver.findElement(By.id("com.you.android:id/et_login_email_or_mobile"));
        usr.sendKeys("hello1@gmail.com");
        Thread.sleep(2000);
        WebElement passwrd = driver.findElement(By.id("com.you.android:id/et_login_pwd"));
        passwrd.sendKeys("123456789");
        Thread.sleep(2000);
        driver.findElementByName("Sign in").click();
        Thread.sleep(5000);
        assertTrue( true );
    }
    @Test
    public void second_sign_in_Click() throws InterruptedException 
    {    
        //HERE I WANT TO REOPEN THE APPLICATION WITH SIGN IN  AFTER CLOSING APP.BECAUSE IN 1st TESTCASE , I HAVE SIGNED IN.this is a 2nd test case    
    }
}

将 @Beforeclass 和 @AfterClass 标签分别更改为 @Before 和 @After。

现在您的 initSimulator() 方法将在每个 @Test 之前被调用，并且 quitDriver() 方法将在它之后被调用。这样，您将在每种情况下重新启动新的驱动程序(带有清晰的应用程序)。

所以 - 如您所见 - 在 JUnit 中，默认情况下每个测试用例都是独立的。

为什么会出现问题？来自@BeforeClass docs :

Sometimes several tests need to share computationally expensive setup (like logging into a database). While this can compromise the independence of tests, sometimes it is a necessary optimization. Annotating a public static void no-arg method with @BeforeClass causes it to be run once before any of the test methods in the class.

顺便说一句，我的 initDriver() 方法看起来像这样，这是处理退出驱动程序的更好方法:

   public void quitDriver() {
        driver.closeApp();
        driver.quit();
        driver = null;
    }

(在你的情况下它是静态的)
