Question

由于Selenium RemoteWebDriver抛出异常，我在自动化测试中间歇性地看到错误。在文本字段（通过RemoteWebElement.getText()）输入文本字段后调用sendKeys()时会发生这种情况。

我已经为下面的一个场景粘贴了堆栈跟踪：

org.openqa.selenium.WebDriverException: [JavaScript Error: "e is null" {file: "file:///tmp/anonymous4777337731209209225webdriver-profile/extensions/fxdriver@googlecode.com/components/command_processor.js" line: 7143}]'[JavaScript Error: "e is null" {file: "file:///tmp/anonymous4777337731209209225webdriver-profile/extensions/fxdriver@googlecode.com/components/command_processor.js" line: 7143}]' when calling method: [nsICommandProcessor::execute]

触发此错误的代码执行以下操作：

private void assertCommentMaxLength()
{
    // An accessor to a text field which containts a selenium.remote.RemoteWebElement.
    final TextareaWebElement comment = this.page.get(Popup.COMMENTS_FIELD);

    comment.clear();

    final String commentString = LONG_STRING_2000_CHARACTERS;

    comment.typeText(commentString);

    assertThat(comment.webElement.getText(), AutoMatchers.length(EXPECTED_LENGTH));
}

为什么偶尔会抛出上述错误？我只是设置文本然后检索它。我需要某种等待语句，因为它是一个长字符串吗？我也看到过这种情况发生在另一个调用RemoteWebElement.getAttribute()的地方，字符串类似。

getText上的RemoteWebElement异常和long String
