为什么Gradle会运行两次测试？

Question

如果我按通常的方式运行测试，一切都很好。 问题是，当我运行Gradle的帮助下运行测试时，它们被执行两次。我使用grandle来分离中小型测试的执行。

这是gradle这个控制台的数据：

Executing tasks: [connectedAndroidTest] 

Configuration on demand is an incubating feature.

为什么gradle会运行两次测试？以及如何避免它？

Answer 1

如果您正在执行connectedAndroidTest，gradle将自动运行connected(FlavorName+BuildType)AndroidTest，看起来您有两种口味（Production和UiTest）。您可能只需运行其中一个命令，而不是运行connectedAndroidTest。
