我得到下面的错误。我是Java的新手，因此任何帮助都将不胜感激。
Cannot invoke "org.openqa.selenium.WebDriver.get(String)" because "this.driver" is null
请参阅下面的代码：
package steps;
import io.cucumber.java.en.Given;
import io.github.bonigarcia.wdm.WebDriverManager;
import org.junit.After;
import org.junit.Before;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
public class hotelBookingFormPage {
public WebDriver driver;
@Before
public void startBrowser() {
WebDriverManager.chromedriver().setup();
driver = new ChromeDriver();
}
@After
public void closeBrowser() {
driver.close();
driver.quit();
}
@Given("I navigate to the hotel booking form page")
public void iNavigateToTheHotelBookingFormPage() {
driver.get("http://hotel-test.equalexperts.io/");
}
如有任何帮助，我们将不胜感激。
import org.junit.After;
import org.junit.Before;
有了这个，您将导入JUnit钩子注释，而不是Cucumber注释。所以Cucumber不知道你想在每个场景前后运行带注释的方法。
黄瓜注释在不同的包中：
import io.cucumber.java.en.Before;
import io.cucumber.java.en.After;
使用Chromedriver的Webdriver接口的强制转换仅在@Before步骤中声明(未使用(，其他步骤不知道。修改如下：
public class hotelBookingFormPage {
public WebDriver driver = new ChromeDriver();
@Before
public void startBrowser() {
WebDriverManager.chromedriver().setup();
}
@After
public void closeBrowser() {
driver.close();
driver.quit();
}
@Given("I navigate to the hotel booking form page")
public void iNavigateToTheHotelBookingFormPage() {
driver.get("http://hotel-test.equalexperts.io/");
}
