Using 测试观察者 http://kentbeck.github.com/junit/javadoc/latest/index.html?org/junit/rules/TestWatcher.html可以解决这个问题(单元测试必须扩展以下内容BaseTest
):
public abstract class BaseTest {
// ...
protected WebDriver driver;
@Rule
public TestRule testWatcher = new TestWatcher() {
@Override
public void starting(Description desc) {
LOG.info("Launching browser...");
driver = Utils.getFirefoxDriver();
}
@Override
public void finished(Description desc) {
LOG.info("Quitting driver...");
driver.quit();
}
@Override
public void failed(Throwable e, Description d) {
LOG.debug("Creating screenshot...");
File scrFile = ((TakesScreenshot) driver).getScreenshotAs(
OutputType.FILE);
String scrFilename = "Screenshot.png";
File outputFile = new File(SCREEN_SHOTS_RESULTS_PATH, scrFilename);
LOG.info(scrFilename + " screenshot created.");
try {
org.apache.commons.io.FileUtils.copyFile(scrFile, outputFile);
} catch (IOException ioe) {
LOG.error("Error copying screenshot after exception.", ioe);
}
}
};
}
Note
Utils.getFirefoxDriver()
返回一个定制的WebDriver
。就像是:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxBinary;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
public class Utils {
// ...
public static WebDriver getFirefoxDriver() {
FirefoxProfile firefoxProfile = new FirefoxProfile();
// Profile customization. For example:
// firefoxProfile.addExtension("firebug-1.8.4-fx.xpi");
// firefoxProfile.setPreference("extensions.firebug.currentVersion","1.8.4");
FirefoxBinary firefox = new FirefoxBinary();
// Firefox customization. For example:
// firefox.setEnvironmentProperty("DISPLAY", display);
WebDriver driver = new FirefoxDriver(firefox, firefoxProfile);
// WebDriver customizations. For example:
// driver.manage().timeouts().implicitlyWait(SHORT_TIMEOUT_S, TimeUnit.SECONDS);
return driver;
}
}
