英文:
Errors when running a JUnit test case via Selenium
问题
以下是你的代码翻译部分：
这是我的 Main Page 类：
public class MainPage {
private WebDriver driver;
public MainPage(WebDriver driver) {
this.driver = driver;
}
@FindBy(xpath = "//form/h3")
private WebElement heading;
}
这是我想通过 JUnit 进行测试的方法：
public String getErrorText(){
return errorMessage.getText();
}
这是我的 JUnit 测试类：
public class MainPageTest {
private WebDriver driver;
private MainPage mainPage;
@Before
public void setUp(){
System.setProperty("webdriver.chrome.driver", "D:\\Intellij IDEA\\testgroup\\drivers\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
driver.manage().window().maximize();
driver.get("https://dtapi.if.ua/login");
mainPage = new MainPage(driver);
}
@Test
public void changeLanguage(){
String heading = mainPage.getHeadingText();
Assert.assertEquals("Authorization", heading);
}
}
但是我遇到了一个错误：
启动 ChromeDriver 80.0.3987.106 (f68069574609230cf9b635cd784cfb1bf81bb53a-refs/branch-heads/3987@{#882})，端口为 6024
仅允许本地连接。
请保护 ChromeDriver 和相关测试框架使用的端口，以防止恶意代码访问。

以及

英文:
Here is my Class Main Page an
private WebDriver driver;
public MainPage(WebDriver driver) {
this.driver = driver;
}
@FindBy(xpath = "//form/h3")
private WebElement heading;
And here is my method that i want to test by JUnit
public String getErrorText(){
return errorMessage.getText();
}
Here my JUnit class
public class MainPageTest {
private WebDriver driver;
private MainPage mainPage;
@Before
public void setUp(){
System.setProperty("webdriver.chrome.driver", "D:\\Intellij IDEA\\testgroup\\drivers\\chromedriver.exe");
driver = new ChromeDriver();
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
driver.manage().window().maximize();
driver.get("https://dtapi.if.ua/login");
mainPage = new MainPage(driver);
}
@Test
public void changeLanguage(){
String heading = mainPage.getHeadingText();
Assert.assertEquals("Authorization",heading);
}
But i'm getting an error:
Starting ChromeDriver 80.0.3987.106 (f68069574609230cf9b635cd784cfb1bf81bb53a-refs/branch-heads/3987@{#882}) on port 6024
Only local connections are allowed.
Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.

你已经初始化了你的PageFactory吗？
尝试以下操作 -
PageFactory.initElements(driver, this);
