标题: Appium 等待的三种方法

1. 1.sleep  eg: Thread.sleep(60000)；强制等待60s
   
2. 2.implicitlyWait
   
3.   driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
   
4.   //隐式等待，全局等待30s不管是否已经加载
   
5. 3.WebDriverWait 显示等待，这个需要增加一定等待时间，显示等待时间可以通过WebDriverWait 和util来决定
   
6. WebDriverWait wait=new WebDriverWait(driver,60);
   
7.   WebElement e=wait.until(new ExpectedCondition<WebElement>(){
   
8.   @Override
   
9.   public WebElement apply(WebDriver d){
   
10.   return d.findElement(By.id("q"));
    
11.   }
    
12.   })
    
13.   只用WebDriverWait是selenium所特有，在java-client中也找不到相应，如果想使用这种方法怎么办？
    
14. 
    
15. 
    
16. 改造轮子，首先添加AndroidDriverWait.java, 其实是将WebDriverWait的类型改成AndroidDriverWait
    
17. 
    
18. 
    
19. 具体代码如下：
    
20. 第一步：创建AndroidDriverWait.java, 其实是将WebDriverWait的类型改成AndroidDriverWait
    
21. import java.util.concurrent.TimeUnit;
    
22. 
    
23. 
    
24. import io.appium.java_client.android.AndroidDriver;
    
25. 
    
26. 
    
27. import org.openqa.selenium.NotFoundException;
    
28. import org.openqa.selenium.WebDriver;
    
29. import org.openqa.selenium.WebDriverException;
    
30. import org.openqa.selenium.TimeoutException;
    
31. import org.openqa.selenium.remote.RemoteWebDriver;
    
32. import org.openqa.selenium.support.ui.SystemClock;
    
33. import org.openqa.selenium.support.ui.Clock;
    
34. import org.openqa.selenium.support.ui.FluentWait;
    
35. import org.openqa.selenium.support.ui.Sleeper;
    
36. 
    
37. 
    
38. 
    
39. 
    
40. 
    
41. 
    
42. public class AndroidDriverWait extends FluentWait<AndroidDriver>{
    
43. public final static long DEFAULT_SLEEP_TIMEOUT=500;
    
44. private final WebDriver driver;
    
45. public AndroidDriverWait(AndroidDriver driver,long timeOutInSeconds){
    
46. this(driver, new SystemClock(), Sleeper.SYSTEM_SLEEPER, timeOutInSeconds, DEFAULT_SLEEP_TIMEOUT);
    
47. }
    
48. public AndroidDriverWait(AndroidDriver driver,long timeOutInSeconds,long sleepInMillis){
    
49. this(driver, new SystemClock(), Sleeper.SYSTEM_SLEEPER, timeOutInSeconds, sleepInMillis);
    
50. }
    
51. 
    
52. public AndroidDriverWait(AndroidDriver driver,Clock clock,Sleeper sleeper,long timeOutInSeconds,long sleepTimeOut){
    
53. super(driver,clock,sleeper);
    
54. withTimeout(timeOutInSeconds,TimeUnit.SECONDS);
    
55. pollingEvery(sleepTimeOut,TimeUnit.MILLISECONDS);
    
56. ignoring(NotFoundException.class);
    
57. this.driver=driver;
    
58. }
    
59.   @Override
    
60.   protected RuntimeException timeoutException(String message,Throwable lastException){
    
61. TimeoutException ex=new TimeoutException(message,lastException);
    
62. ex.addInfo(WebDriverException.DRIVER_INFO,driver.getClass().getName());
    
63. if(driver instanceof RemoteWebDriver){
    
64. RemoteWebDriver remote=(RemoteWebDriver) driver;
    
65. if(remote.getSessionId()!=null){
    
66. ex.addInfo(WebDriverException.SESSION_ID,remote.getSessionId().toString());
    
67. }
    
68. if(remote.getCapabilities()!=null){
    
69. ex.addInfo("Capabilities",remote.getCapabilities().toString());
    
70. }
    
71. }
    
72. throw ex;
    
73.   }
    
74.    
    
75. }
    
76. 
    
77. 
    
78. 第二步：接着需要修改接口：ExpectedCondition，将其WebDriver的类型替换为AndroidDriver
    
79. 
    
80. 
    
81.    import com.google.common.base.Function;
    
82.    import io.appium.java_client.android.AndroidDriver;
    
83.    public interface ExpectedCondition<T> extends Function<AndroidDriver,T>
    
84.    {}
    
85. 第三步：经过第一二步后，就可以在appium 中直接使用；
    
86.        WebElement showClose=new AndroidDriveWait(driver,60).until(new ExpectedCondition<WebElement>()｛
    
87.        public WebElement apply(AndroidDriver d){
    
88.        return d.findElemnt(By.id("com.zhihu.android:id/showcase_close"));
    
89. 
    
90. 
    
91.        }
    
92.        ｝);
