java + selenium测试框架（之测试驱动） 版本演化三

本节将使用properity文件来管理程序的设置，并且完成Test的基类，用于辅助测试。

增加初始化WebDriver的代码

项目中增加配置文件

在工程项目的resource下面，增加一个配置文件（selenium-vars.properties）：

#WebDriverTypes or Browser to be tested: InternetExplorer  Firefox   Chromewebdriver.type=Firefox#Path of ChromeDriver webdriver.chrome.driver.path=lib/chromedriver.exe#Path of IEDriverwebdriver.ie.driver.path=lib/IEDriverServer.exe

读取和保存配置

然后用ConfigurationSettings来保存这些配置变量：

public class ConfigurationSettings {        private static Properties props = null;        private final static String SELENIUM_CONFIG="selenium-vars.properties";        static{            try {                props = new Properties();                InputStream in = ConfigurationSettings.class.getClassLoader().getResourceAsStream(SELENIUM_CONFIG);                props.load(in);            } catch (Exception e) {                throw new RuntimeException("ConfigurationSettings initialize failed.", e);            }        }        public static String getProperty(String propertyName){            return props.getProperty(propertyName);        }        /**         * WebDriver类型         */        public static final String WEBDRIVER_TYPE = getProperty("webdriver.type").trim();        /**         * IEdriver的路径         */        public static final String WEBDRIVER_IE_DRIVER_PATH = getProperty("webdriver.ie.driver.path").trim();        /**         * Chromedriver的路径         */        public static final String WEBDRIVER_CHROME_DRIVER_PATH  = getProperty("webdriver.chrome.driver.path").trim();}

用DriverFactory完成初始化

下面，完成驱动程序的初始化：

public class DriverFactory {    private static DriverType DEFAULT_DRIVER_TYPE = DriverType.Firefox;    protected Logger logger = LoggerFactory.getLogger(getClass());    private static DriverFactory instance = null;    static {        instance = new DriverFactory();    }    public static DriverFactory getInstance() {        return instance;    }    public WebDriver getDriver() {        DriverType type = DEFAULT_DRIVER_TYPE;        try {            type = Enum.valueOf(DriverType.class, ConfigurationSettings.WEBDRIVER_TYPE);        }        catch (Exception ex) {            logger.warn("Parse WebDriver.Type failed, use default driver type: " + DEFAULT_DRIVER_TYPE.name());            logger.debug(ex.getMessage(), ex);        }        return type.getDriver();    }}

对应的DriverType中负责实际的驱动程序初始化：

public enum DriverType {    InternetExplorer {        @Override        public WebDriver getDriver() {            if (!StringUtils.isEmpty(ConfigurationSettings.WEBDRIVER_IE_DRIVER_PATH)) {                System.setProperty(InternetExplorerDriverService.IE_DRIVER_EXE_PROPERTY,ConfigurationSettings.WEBDRIVER_IE_DRIVER_PATH);            }            DesiredCapabilities ieCapabilities = DesiredCapabilities.internetExplorer();            ieCapabilities.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,true);            return new InternetExplorerDriver(ieCapabilities);        }    },    Firefox {        @Override        public WebDriver getDriver() {            return new FirefoxDriver();        }    },    Chrome {        @Override        public WebDriver getDriver() {            if (!StringUtils.isEmpty(ConfigurationSettings.WEBDRIVER_CHROME_DRIVER_PATH)) {                System.setProperty(ChromeDriverService.CHROME_DRIVER_EXE_PROPERTY,ConfigurationSettings.WEBDRIVER_CHROME_DRIVER_PATH);            }            return new ChromeDriver();        }    };    public abstract WebDriver getDriver();}

完成TestBase

public abstract class TestBase {    protected Logger logger = LoggerFactory.getLogger(getClass());    protected WebDriver driver = null;    /**     * 用于硬性的等待     * @param seconds     */    public void sleep(int seconds) {        try {            TimeUnit.SECONDS.sleep(seconds);        } catch (InterruptedException e) {            e.printStackTrace();        }    }    @BeforeClass(alwaysRun = true)    public void setUpTestBase(ITestContext testContext) {        try{            driver = DriverFactory.getInstance().getDriver();         } catch(Exception e ) {             quitDriver();             Assert.fail("SetUp failed.", e);         }    }    @AfterClass    public void quitDriver() {        try{            if(driver != null)                driver.quit();        }   finally {            driver = null;        }    }}

Demo程序

public class BaiduMainBaseTest extends TestBase {    BaiduMainPage page = null;    @BeforeMethod    public void initPage() {        String path = "http://www.baidu.com/";        page = new BaiduMainPage(driver);        page.openAndWait(path);        PageFactory.initElements(driver, page);    }    @Test    public void testSearch(){        String text="apple";        page.SearchText(text);        sleep(1);        System.out.println(driver.getTitle());        Assert.assertTrue(driver.getTitle().contains(text));        System.out.println(page.getCurrentUrl());    }    @Test    public void testnews(){        System.out.println(page.getCurrentUrl());        page.clickNewsIndex();        page.sleep(1);        System.out.println(page.getCurrentUrl());        Assert.assertTrue(page.getCurrentUrl().contains("news.baidu.com"));    }}

Page增加等待

/** * 加载页面，并等待加载完成。 * @param url */public void openAndWait(String url) {    Selenium selenium = new WebDriverBackedSelenium(driver,url);    driver.get(url);    selenium.waitForPageToLoad("5000");}
