org.openqa.selenium.WebDriverException: disconnected: 在使用 Selenium 和 Chromedriver 的測試執行期間收到 Inspector.detached 事件錯誤

Question

我知道 Selenium 是一種自動化測試工具，但我正在嘗試將其用於 RPA（與我的工作環境有關）

我已經下載了 java 代碼，它完全按照我想要的方式運行。 它從 Excel 表中獲取數據，將數據轉換為 java 對象，然后將數據輸入到 Web 應用程序中。 它適用於前 20-25 個條目，然后開始變慢，最終使應用程序崩潰。 我有幾千行要輸入。

我試過在禁用緩存的情況下啟動 chrome webdriver，但沒有解決問題。

這是禁用緩存的代碼。

System.setProperty("webdriver.chrome.driver","C:\\\\DRIVERS\\\\chromedriver.exe");
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability("applicationCacheEnabled", false);
WebDriver webDriver = new ChromeDriver(cap);
WebDriverWait wait = new WebDriverWait(webDriver, 20);
JavascriptExecutor js = (JavascriptExecutor) webDriver;

我正在使用 for 每個循環來鍵入數據。

我讀到在測試期間嘗試打開 Chrome DevTools 時會發生這種情況，但我的代碼根本沒有這樣做。 請指教。

chrome緩存填滿是否有問題？ 如果是這樣，我必須每 30 個左右的條目清除一次嗎？

Answer 1

這個錯誤信息...

org.openqa.selenium.WebDriverException: disconnected: received Inspector.detached event

...暗示WebDriverException由於Inspector.detached 事件而引發。

從您的代碼試驗中可以明顯看出您正在使用Thread.sleep(n); 等待元件可點擊/ interacable調用sendKeys()這是不理想的方式，如：

Thread.sleep()在給定的秒數內暫停當前線程的執行。 參數可能是一個浮點數，以指示更精確的睡眠時間。 實際的暫停時間可能比請求的少，因為任何捕獲的信號都會在執行該信號的捕獲例程后終止 sleep()。 此外，由於系統中其他活動的調度，暫停時間可能比任意數量的請求長。

sendKeys()調用sendKeys()和Thread.sleep()可能模擬發送以下任一內容：

• Ctrl + Shift + I
• Ctrl + Shift + J
• Ctrl + Shift + C
• F12

每個都將嘗試打開google-chrome-devtools

現在，根據文章DevTools 窗口會一直關閉，如果您嘗試打開 google-chrome-devtools ，ChromeDriver 會自動斷開連接。

解決方案

一個完整的證明解決方案是用ExplicitWait替換Thread.sleep()和ImplicitWait 的所有實例

額外考慮

根據DesiredCapabilities的文檔， applicationCacheEnabled是一個讀/寫功能，它采用一個boolean值並配置會話是否可以與應用程序緩存交互。

執行

applicationCacheEnabled可以通過以下任一方式進行配置：

DesiredCapabilities capability = DesiredCapabilities.chrome();
capability.setCapability("applicationCacheEnabled", false);

或者

DesiredCapabilities capability = DesiredCapabilities.chrome();
capability.setCapability(CapabilityType.SUPPORTS_APPLICATION_CACHE, false);

所以有效地你的代碼塊將是：

System.setProperty("webdriver.chrome.driver","C:\\DRIVERS\\chromedriver.exe");
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability(CapabilityType.SUPPORTS_APPLICATION_CACHE, false);
ChromeOptions opt = new ChromeOptions();
opt.merge(cap);
WebDriver driver = new ChromeDriver(opt);

Answer 2

只需添加這一行：

chromeOptions.setPageLoadStrategy(PageLoadStrategy.NONE);

這應該可以解決問題。
