我使用 Xamarin UITest 框架为我的 Xamarin 应用程序创建了自动 Android 和 iOS UI 测试。在本地运行测试时,它们运行良好,但在 Bitrise CI 上运行它们时,iOS 测试运行良好,但 Android UI 测试一直失败,并出现以下异常:
StartFirstActivity_WaitForActivity_ExpectButtonToHaveText
SetUp : System.Exception : Timed out waiting for result of ClearAppData2

Android 测试使用 Xamarin.UITest 版本 1.3.5 运行。这很重要,因为在1.3.3 版本之前似乎一直存在错误。我也尝试忽略失败的测试,但随后测试运行程序因其他 Android 测试而失败。有趣的是,有时个别测试会通过。
有没有人遇到过这种行为?你对如何解决这个问题有什么建议吗?
反编译 CommandAdbClearAppData (引发异常)时,我看到
// ISSUE: reference to a compiler-generated field
string str1 = string.Format("/data/data/{0}/files/calabash_failure.out", (object)executeCAnonStorey0.svr);
// ISSUE: reference to a compiler-generated field
string str2 = string.Format("/data/data/{0}/files/calabash_finished.out", (object)executeCAnonStorey0.svr);
while (DateTime.UtcNow < utcNow + TimeSpan.FromSeconds(10.0))
{
if (func(string.Format("ls {0}", (object)str1)).Output.Trim().Equals(str1))
throw new Exception("Clear app data failed with " + func(string.Format("cat {0}", (object)str1)).Output);
if (func(string.Format("ls {0}", (object)str2)).Output.Trim().Equals(str2) && func(string.Format("cat {0}", (object)str2)).Output.Trim().Equals("SUCCESSFUL"))
return;
}
throw new Exception("Timed out waiting for result of ClearAppData2");
表示十秒内找不到生成的文件。是不是模拟器太慢了,模拟器需要十多秒才能创建这些文件?
