我对Selenium Web驱动程序和Testng的新事物相对较新，我正在编码一个项目，其中两个Java类同时运行。问题是，对于每个类@Test方法。导致此错误：

Question

public class baseTest {

    protected static ThreadLocal<WebDriver> driver = new ThreadLocal<>();
    protected static ThreadLocal<FluentWait<WebDriver>> wait = new ThreadLocal<>();
    protected SoftAssert softAssert;

    @BeforeSuite
    public void setUpSuite() {
        System.out.println("Executing method - setUpSuite\n\n");
    }

    @AfterSuite
    public void tearDownSuite() {
        System.out.println("Executing method - tearDownSuite\n\n");
        // Cleanup
        if (driver.get() != null) {
            driver.get().quit();
            driver.remove();
        }
        if (wait.get() != null) {
            wait.remove();
        }
    }

    @BeforeClass
    public void setUpClass() {
        System.out.println("Executing method - setUpClass\n\n");

        configProp config = new configProp();
        driver.set(config.initializeDriver());
        wait.set(config.initializeFluentWait(driver.get())); // Initialize FluentWait before the class
       

        // Perform login
        config.login(driver.get());
        System.out.println("Performed login\n\n");

        // Call the testPostmanAuth class
        System.out.println("Calling PostmanAuth\n\n");

        TestPostmanAuth postmanAuth = new TestPostmanAuth();
        try {
            postmanAuth.testAuthorizationLoginOnPostman();
        } catch (IOException | URISyntaxException e) {
            e.printStackTrace();
        }
    }

    @AfterClass
    public void tearDownClass() {
        System.out.println("Executing method - tearDownClass\n\n");

        // Cleanup for the current class
        if (driver.get() != null) {
            driver.get().quit();
            driver.remove();
        }
        if (wait.get() != null) {
            wait.remove();
        }
    }

    
    @BeforeMethod
    public void beforeMethod() {
        System.out.println("Executing method - beforeMethod\n\n");
        softAssert = new SoftAssert(); // Initialise SoftAssert before each test method

        // Check if driver and wait are initialised
        if (driver.get() == null || wait.get() == null) {
            throw new RuntimeException("WebDriver or FluentWait instance is not initialized.");
        }
    }

    @AfterMethod
    public void afterMethod() {
        System.out.println("Executing method - afterMethod\n\n");
        softAssert.assertAll(); // Ensure assertAll is called after each test method

    }

    // Getters for driver and wait
    public WebDriver getDriver() {
        return driver.get();
    }

    public FluentWait<WebDriver> getWait() {
        return wait.get();
    }
}

在另一个文件中启动了驱动程序和流利的等待：

public class configProp {
 
    public WebDriver initializeDriver() {
        System.setProperty("webdriver.gecko.driver",
                "URLGoesHere");
 
        FirefoxOptions options = new FirefoxOptions();
        options.setCapability("webSocketUrl", true); // Enable WebDriver BiDi
 
        WebDriver driver = new FirefoxDriver(options);
        driver.manage().window().maximize();
        return driver;
    }
 
    public FluentWait<WebDriver> initializeFluentWait(WebDriver driver) {
        // Initialise FluentWait
        FluentWait<WebDriver> wait = new FluentWait<>(driver).withTimeout(Duration.ofSeconds(20))
                .pollingEvery(Duration.ofMillis(500)).ignoring(NoSuchElementException.class);
        return wait;
    }

然后还有其他两个文件，其中最高的类别是扩展的 这两个文件是@test方法所在的位置。 Fulll错误：删除了某些零件以供发布：

Method致电.navigate：

    public void switchToIframe() {
        WebElement iframe = wait.get().until(ExpectedConditions.visibilityOfElementLocated(By.tagName("iframe")));
        driver.get().switchTo().frame(iframe);
    }
    
        @Test(priority = 3, dependsOnMethods = {"nextRequestAssignNArrive" }, description = "Refreshes the page so processing can be done")
        public void refresh() throws InterruptedException {
            System.out.println("\n\nRefreshing the page after some time...");
    
    // Adding a sleep for 30 seconds before refreshing to make sure processing has
    // complete and incident is In Progress
            Thread.sleep(30 * 1000);
    
    // Refresh the page
            driver.get().navigate().refresh();
    
            System.out.println("Page refreshed...");
    
            Thread.sleep(10 * 1000); // just waiting for refresh to be done
    
    // make sure to switch to iframe after refresh
            switchToIframe();
        }

来自

priority = 3, dependsOnMethods = {"nextRequestAssignNArrive" },

您的测试应不会出错。我已经修改了您的刷新测试以反映建议的更改：

refresh()

我看不到根据优先级进行测试的原因。尽管如此，您的测试还是按照安排的方式进行的，例如堆栈；首先执行顶级测试，其余的则遵循。
