精简版 Selenium PageFactory, Annotation 实例

精简版 Selenium  PageFactory, Annotation 实例。

先是类: HomePage

package com.test;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
public class HomePage {
    @FindBy(id="kw")
    public WebElement SearchTextField;
    
    @FindBy(id="su")
    public WebElement SearchButton;
    
    public void clearSearchTextField() {
        SearchTextField.clear();
    }
    
    public void inputSearchTextFeild(String str) {
        SearchTextField.sendKeys(str);
    }
    
    public void clickSearchButton(){
        SearchButton.click();
    }
}

再是定义的 Annotation 类，起名叫：AnnotationFactory。(其中的 RetentionPolicy.RUNTIME 很重要)

package com.test;

import java.lang.annotation.Documented;
import java.lang.annotation.Inherited;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;

@Inherited
@Retention(RetentionPolicy.RUNTIME)

@Target(value = {ElementType.TYPE, ElementType.METHOD})

@Documented
public @interface AnnotationFactory {
    String batchName();
    int testOrder() default 0;
    String author() default "allen";
}

 具体的 Test Case, 用 PageFactory 实例化 HomePage 类，同时也添加了 annotation

package com.test;
import java.util.concurrent.TimeUnit;
import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.support.PageFactory;

@AnnotationFactory(batchName="Smoketest1", testOrder = 2, author = "Mike")
public class SearchBD {
  private WebDriver driver = new FirefoxDriver();
  private String baseUrl = "https://www.baidu.com/";
  HomePage homePage = PageFactory.initElements(driver, HomePage.class);
 
  @Test
  public void testHelloWorld() throws Exception {
      driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
      driver.manage().window().maximize();
      driver.get(baseUrl);
  
      //Use page factory and its methods
    homePage.clearSearchTextField();
    homePage.inputSearchTextFeild("Hello world");
    homePage.clickSearchButton();
    driver.quit();
  }
}

 那么我们如何解析那些 annotation, 然后进一步根据 batchname, testOrder 分类执行呢？

 这个类就是解析 annotation 的：

package com.test;
import java.lang.annotation.Annotation;
public class GetAnnotations {
    public static void main(String[] args) throws ClassNotFoundException {
        getAnnotationData("com.test.SearchBD");
    }
    
    private static void getAnnotationData(String caseName) throws ClassNotFoundException {
        System.out.println("---start----");
        Annotation[] annotations = Class.forName(caseName).getAnnotations();
        for(Annotation annotation : annotations)
        {
            if(annotation instanceof AnnotationFactory)
            {
                AnnotationFactory af = (AnnotationFactory) annotation;
                String batchName = af.batchName();
                int testOrder = af.testOrder();
                String author = af.author();
                System.out.println(batchName + " " + testOrder + " " + author);
            }
        }
    }
}
