如何在selenium webdriver测试框架中更有效地使用log4j

Question

我正在从事selenium webdriver的一个自学项目，并使用log4j进行日志记录。有一个测试类——包含所有测试用例作为方法；有一个页面类——包含测试类可以使用的所有web元素和方法

我应该如何使用log4j？测试等级：

public class ConfiguringPropertiesFile {
    private WebDriver driver;
    private String baseUrl;
    static Logger log = Logger.getLogger(ConfiguringPropertiesFile.class);

@Before
public void setUp() throws Exception {
    driver = new FirefoxDriver();
    baseUrl = "https://www.some-website.com/";

    // Maximize the browser's window
    driver.manage().window().maximize();
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
}

@Test
public void test() {
    PropertyConfigurator.configure("log4j.properties");
    driver.get(baseUrl);
    SearchPage.navigateToFlightsTab(driver);
    log.info("Navigate to flights tab");
    SearchPage.fillOriginTextBox(driver, "New York");
    SearchPage.destinationTextBox(driver).sendKeys("Chicago");
    log.info("Enter destination city");
    SearchPage.departureDateTextBox(driver).sendKeys("12/25/2014");
    log.info("Enter departure date");
    SearchPage.returnDateTextBox(driver).sendKeys("12/31/2014");
    log.info("Enter return date");
}

}

页面类：

public class SearchPage {
public static WebElement element = null;
static Logger log1 = Logger.getLogger(SearchPage.class);

/**
 * Returns the flight origin text box element
 * @param driver
 * @return
 */
public static WebElement originTextBox(WebDriver driver) {
    element = driver.findElement(By.id("flight-origin"));
    return element;
}

public static void fillOriginTextBox(WebDriver driver, String origin) {
    PropertyConfigurator.configure("log4j.properties");
    element = originTextBox(driver);
    element.sendKeys(origin);
    log1.info("Entering the source city as " + origin);
}

/**
 * Returns the flight destination text box element
 * @param driver
 * @return
 */
public static WebElement destinationTextBox(WebDriver driver) {
    element = driver.findElement(By.id("flight-destination"));
    return element;
}

}

在这种情况下，我在两个类中初始化log4j，然后最大的问题是我必须在每个方法中调用属性配置器。

我怎样才能以更好的方式初始化它，而不必每次都调用Property tyConfigurator？

您可能希望有一个单独的类，可以在其中初始化log4j，并从该类中调用一个方法，以在其他每个类中获得log4j的实例。在下面的示例中，您可以从任何其他类调用createLogger（）方法来获取Log4j的实例，例如use:private Logger log=Logg。createLogger（）；

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.Properties;
import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;

public class Logg {

private static Logger _logger;
private static final String fileName = "defaultlog";
private static final String dateAndTimeFormat = "MM-dd-yyyy_hh.mm.ss";
private static final String logProperttFilePath = "./src/main/resources/com/framework/properties/log4j.properties";

static {
    /**
     * This is the static block which appends the log file name with the
     * timestamp to make it unique
     */
    try {
        String dateTime = DateAndTime
                .getFormattedCurrentDateAndTime(dateAndTimeFormat);
        String FileName = fileName + "-" + dateTime + ".log";
        File file = new File("logs/" + FileName);

        if (file.createNewFile()) {
            Properties props = new Properties();
            props.load(new FileInputStream(logProperttFilePath));
            props.setProperty("log4j.appender.File.File", "logs/"
                    + FileName);
            LogManager.resetConfiguration();
            PropertyConfigurator.configure(props);
            System.out.println("Property log4j.appender.File.File = logs/"
                    + FileName);
        }
    } catch (IOException ex) {
        ex.printStackTrace();
        System.out.print("IO Exception in static method of Logger Class. "
                + ex.getMessage());
        System.exit(-1);
    }

}

/**
 * This method creates instance of the Logger class coming from log4j jar by
 * implementing a singelton
 * 
 * @return _logger - new instance if no instance exist else an existing
 *         instance if the method is invoked previously
 */
public static Logger createLogger() {
    if (_logger == null) {
        _logger = LogManager.getLogger(Logg.class);
        return _logger;
    } else
        return _logger;
}
}
