为什么chrome驱动程序不能在@Before中工作？

Question

我有一个简单的代码

  public class PageAvailable {
            @Test
            public void test() {
                System.setProperty("webdriver.chrome.driver", "C:/Users/JARs/chromedriver_win32/chromedriver.exe");
                WebDriver driver = new ChromeDriver();
                driver.get("https://....net");
                System.out.println(driver.getTitle());
                driver.close();
            }}

public class PageAvailable {
WebDriver driver = new ChromeDriver();
@Before
public void be(){
    System.setProperty("webdriver.chrome.driver", "C:/Users/JARs/chromedriver_win32/chromedriver.exe");
    driver.get("....net");

}
@Test
public void test() {
    driver.get("https://...net");
    System.out.println(driver.getTitle());
}
@After
public void af(){
driver.close();
}}  

我觉得我身边少了点什么。
谢谢你的帮助。

WebDriver对象初始化应在设置“WebDriver.Chrome.Driver”属性后进行。

public class PageAvailable {
WebDriver driver;
@Before
public void be(){

//Set Chromedriver Path
System.setProperty("webdriver.chrome.driver","C:/Users/JARs/chromedriver_win32/chromedriver.exe");

// initialize ChromeDriver instance with the chromdriver exe as set in above line.
driver = new ChromeDriver();

driver.get("....net");

}
@Test
public void test() {
 //Load your URL
driver.get("https://...net");
System.out.println(driver.getTitle());
}
@After
public void af(){
driver.close();
}}  

您可以使用的其他选项是，在环境变量set chromedriver.exe path中，在这种情况下不需要设置system属性。
