java - 以下代码的 selenium webdriver 中的空指针异常

问题描述

        public class NewTest 
          {
        @FindBy(id="btnSearch")
        public WebElement search;
        public WebDriver driver;

         @Test
         public void openMyBlog() {
         driver.manage().window().maximize();
         driver.get("url");

           search.click();
             try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        }

      @BeforeClass
      public void beforeClass() {

          System.setProperty("webdriver.chrome.driver", "D:\\Driver\\chromedriver_win32\\chromedriver.exe");
          driver  = new ChromeDriver();
      }

      @AfterClass
      public void afterClass() {
          driver.close();
      }
    }

收到如下错误：
