java - 错误 Selenium 无法检索文档状态已断开 : received Inspector. 分离事件

标签 java selenium

我有一段代码可以通过网页中的 Selenium 来自动化 Java 测试。 Java代码发布在这个问题中，此外XML中的Pom和我得到的Error也发布在这里。问题是有时并不总是发生，但我不知道问题是什么。我的 Chrome 版本是:版本 78.0.3904.87。提前感谢任何帮助。

System.setProperty("webdriver.chrome.driver",
                "C:\\Users\\afp2\\Downloads\\maven-examples-master\\maven-examples-master\\java-project\\drivers\\chromedriver.exe");
        WebDriver browser = new ChromeDriver();
        browser.get("http://localhost:14612/Modelo_Experto_Amazonas_TC.aspx");
        browser.findElement(By.id("txtLogin")).sendKeys("andres");
        browser.findElement(By.id("txtClave")).sendKeys("burocr");
        browser.findElement(By.id("BLogin")).click();
        if (waitForNotElement(browser, By.id("dtlFinal_imbReporte_216"))) {
            browser.findElement(By.id("dtlFinal_imbReporte_216")).click();
        }
        browser.findElement(By.id("txt_OtrosGastos")).sendKeys("100");
        Select dropdown = new Select(browser.findElement(By.id("ddlTipoCliente")));
        dropdown.selectByVisibleText("DEPENDIENTE");
        browser.findElement(By.id("txtNumeroDocumentoSolicitante")).sendKeys("1722714795");
        browser.findElement(By.id("txt_ingresos")).sendKeys("1500");
        browser.findElement(By.id("btnAceptar")).click();

接下来是 pom:

最佳答案

当 selenium 尝试访问不再可用的元素时，这是一个常见的异常。

// pseudo code example:
webDriver.get("abc.com");
Element button = webDriver.findElement( button selector );
webDriver.get("xyz.com");
button.click();  // exception here


// another example:
Element button = webDriver.findElement( button selector );

// let's assume, after clicking the button 
// JS performs some UI events and then removes the button from DOM
button.click(); // UI actions performed
button.click(); // exception

也许您应该尝试记录每个操作以找到不稳定的确切行。它应该有助于进一步调查。
