我正在使用Selenium为Vaadin应用编写浏览器测试。在Chrome浏览器的开发工具中，控制台显示了不同日志级别(TRACE、SEVERE、WARNING)的日志。以下代码设置了我的测试驱动程序：
@RunOnHub
public abstract class SmokeTestCase extends ParallelTest {
...
final ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.setHeadless(false);
final LoggingPreferences logPrefs = new LoggingPreferences();
logPrefs.enable(LogType.BROWSER, Level.ALL);
chromeOptions.setCapability(CapabilityType.LOGGING_PREFS, logPrefs);
setDriver(new ChromeDriver(chromeOptions));
...
我的 Vaadin 应用程序以 DEV 模式运行。使用以下代码，我正在尝试通过测试驱动程序检索所有浏览器日志:
final LogEntries entries = this.driver.manage().logs().get(LogType.BROWSER);
for (LogEntry entry: entries) {
System.out.println(entry);
final String line = String.format("[%s] - %s - %s", entry.getLevel().getName(), entry.getTimestamp(), entry.getMessage());
if (entry.getLevel() == Level.SEVERE) {
System.err.println(line);
} else {
System.out.println(line);
}
}
很遗憾，我只能接收到WARNING和SEVERE类型的日志，INFO和TRACE类型的日志无法获取。我是不是做错了什么？
我的方法类似于这个链接中的方法：如何使用Selenium获取Chrome浏览器控制台日志[INFO]条目 我们还尝试启用和请求DRIVER或CLIENT类型的日志 - 但它们是空的。
