使用WebDriver做Web自动化的时候,org.openqa.selenium.support.ui中提供了非常便捷好用的WebDriverWait类继承FluentWait<WebDriver>,所以可以使用FluentWait类中until方法和ExpectedCondition<T>接口进行显示等待的定义,比如某个元素的可见或者可点击等条件,在规定的时间之内等不到指定条件那么就跳出Exception。最近使用appium做客户端的自动化时发现AppiumDriver无法使用WebDriverWait类,是由于WebDriverWait继承于FluentWait<WebDriver>,而WebDriver接口是没有定义findElementByAccessibilityId()、findElementByIosUIAutomation()、findElementByAndroidUIAutomator()的,所以appium想使用像WebDriverWait的显示等待功能,就必须自己封装造*了。
①首先依葫芦(WebDriverWait)画瓢写AppiumDriverWait.java
package com.netease.media.qa.base.util;
import org.openqa.selenium.NotFoundException;
import org.openqa.selenium.TimeoutException;
import org.openqa.selenium.WebDriverException;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.support.ui.Clock;
import org.openqa.selenium.support.ui.FluentWait;
import org.openqa.selenium.support.ui.Sleeper;
import org.openqa.selenium.support.ui.SystemClock;
import io.appium.java_client.AppiumDriver;
import java.util.concurrent.TimeUnit;
public class AppiumDriverWait extends FluentWait<AppiumDriver> {
public final static long DEFAULT_SLEEP_TIMEOUT = 500;
private final AppiumDriver driver;
public AppiumDriverWait(AppiumDriver driver, long timeOutInSeconds) {
this(driver, new SystemClock(), Sleeper.SYSTEM_SLEEPER, timeOutInSeconds, DEFAULT_SLEEP_TIMEOUT);
}
public AppiumDriverWait(AppiumDriver driver, long timeOutInSeconds, long sleepInMillis) {
this(driver, new SystemClock(), Sleeper.SYSTEM_SLEEPER, timeOutInSeconds, sleepInMillis);
}
public AppiumDriverWait(AppiumDriver driver, Clock clock, Sleeper sleeper, long timeOutInSeconds,
long sleepTimeOut) {
super(driver, clock, sleeper);
withTimeout(timeOutInSeconds, TimeUnit.SECONDS);
pollingEvery(sleepTimeOut, TimeUnit.MILLISECONDS);
ignoring(NotFoundException.class);
this.driver = driver;
}
@Override
protected RuntimeException timeoutException(String message, Throwable lastException) {
TimeoutException ex = new TimeoutException(message, lastException);
ex.addInfo(WebDriverException.DRIVER_INFO, driver.getClass().getName());
if (driver instanceof RemoteWebDriver) {
RemoteWebDriver remote = (RemoteWebDriver) driver;
if (remote.getSessionId() != null) {
ex.addInfo(WebDriverException.SESSION_ID, remote.getSessionId().toString());
}
if (remote.getCapabilities() != null) {
ex.addInfo("Capabilities", remote.getCapabilities().toString());
}
}
throw ex;
}
}
②然后还要需要修改ExpectedCondition接口,将其WebDriver的类型替换为AppiumDriver
package com.netease.media.qa.base.util;
import com.google.common.base.Function;
import io.appium.java_client.AppiumDriver;
public interface ExpectedConditionForAppium<T> extends Function<AppiumDriver, T>{
}
③接下来就可以在框架封装的方法类中用appium的显示等待啦
return new AppiumDriverWait(driver,DriverBase.stepInterval).until(new ExpectedConditionForAppium<WebElement>(){
public WebElement apply(AppiumDriver driver){
WebElement element = DriverBase.Andriver.findElementByAndroidUIAutomator("new UiSelector().resourceId(\""+locator+"\")");
return element.isDisplayed() ? element : null;
}
});
