错误Selenium无法检索已断开连接的文档状态：接收到Inspector.detached事件

• 问答

我有一个代码，可以通过网页中的Selenium自动执行Java中的测试。代码Java贴在此问题中，此外XML的Pom和我得到的错误也贴在这里。问题是它有时不总是发生，但我不知道是什么问题。我的Chrome版本是：78.0.3904.87版。任何帮助都在此先感谢。

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();

然后是pom：

当硒试图访问不再可用的元素时，这是一个常见的例外。

// 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。
