java.io.IOException : Connection was aborted by the software in your host machine with Sendkey() in selenium java 异常

Question

操作系统:Win7 64位 浏览器:Chrome

我正在完成我的作业，用 selenium 测试一个程序。 我正在使用教授提供的代码，它在我的 localhost:8080 上创建了一个网络应用程序(所以应该没有任何连接问题)

public void canConenctTwoPlayers() {
    // connect
    //2: missing code
    this.indexPage.connect.click();
    assertThat(this.indexPage.hasText("Successfully connected to the game with unique "), is(true));
    this.indexPage.numberPlayers.click();
    this.indexPage.numberPlayers.sendKeys("2");
    this.indexPage.open.click();
    //second connect
    ChromeDriver second_player = quickConnectAnotherUser();
    //3: missing code
    assertThat(this.indexPage.hasText("The game is now ready to begin"), is(true));
    // quit
    //4: missing code
    disconnectSecondUser(second_player);
    this.indexPage.disconnect.click();      
}

这里的 numberPlayers 是窗口中的元素，顾名思义，输入玩家的数量。但是当我使用 sendKeys 时，它给了我这个异常

java.io.IOException: java.util.concurrent.ExecutionException: 
java.io.IOException: Connection was aborted by the software in your host machine

当我注释掉发送键时，代码运行良好。

Answer 1

这个错误信息...

java.io.IOException: java.util.concurrent.ExecutionException: 
java.io.IOException: Connection was aborted by the software in your host machine

...暗示异常是由于并发执行引起的。

根据讨论 ConnectionAbortedError: [WinError 10053] An established connection was aborted by the software in your host machine with GeckoDriver and Firefox当您尝试在 JavaScript 时调用 sendKeys() 时会出现此问题/jQuery仍然活跃。

解决方案

解决方案是为 JavaScript 引入 WebDriverWait/jQuery使用 ExpectedConditions 中的任何一个来完成:

• elementToBeClickable(By locator) : 期望检查元素可见并启用，以便您可以单击它。
• elementToBeClickable(WebElement element) : 期望检查元素可见并启用，以便您可以单击它。
