我希望对我的当前Android应用进行预发布测试。
我的测试要求如下：
My Application must not appear in the Google Play Store or...
Only invited testers can see the Applications Play Store Page
Only invited users can participate in testing.
Testers do not have to have a gmail account.
Total number of testers < 10,000.
Testers are automatically contacted with download link.
据我在Google网站上阅读（聊天）的内容，我的选择是Alpha测试或Beta测试。
关于Beta测试
Open beta
Use an open beta when you want any user who has the link to be able to join your beta with just one click.
One of the advantages of an open beta is that it allows you to scale to a large number of testers.
However, you can also limit the maximum number of users who can join.
Closed beta
Using email addresses – If you want to restrict which users can access your beta, you have a new option:
you can now set up a closed beta using lists of individual email addresses which you can add individually
or upload as a .csv file. These users will be able to join your beta via a one-click opt-in link.
Closed beta
with Google+ community or Google Group – This is the option that you’ve been using today, and you can continue
to use betas with Google+ communities or Google Groups. You will also be able to move to an open beta
while maintaining your existing testers.
Beta可以满足我几乎所有的需求，但是我不能允许我的应用在Play商店被搜索到，也不想要求我的测试人员必须拥有/使用Gmail账户，所以Beta测试不适用。
因此，我的唯一选择就是Alpha。
我仍然不清楚可用的Alpha测试“口味”。
如果我必须手动分发Alpha应用程序链接，为什么要上传电子邮件列表？
上传的电子邮件列表有什么作用？
上传的电子邮件列表用于控制对Alpha apk的访问权限吗？
我能运行数千名测试人员的Alpha测试组吗？
