Use TestNG for android testing - suitable? Potential problems?

Question

Is TestNG suitable for testing Android apps?

What pitfalls or trade-offs might be encountered?

The default examples for Android testing, seem to all use JUnit. Is that for a reason?

Do you know real-world usages of TestNG for Android app testing?

Particular considerations:

• compatibility with instrumentation tests
• compatibility with Gradle workflow
• AndroidJUnitRunner - need to find TestNG equivalent? Exists?
• compatibility with standard tools used for Android (Testing Support Library, Espresso, etc.)
• parametric tests
• IDE support (Android Studio)
• code coverage
• will TestNG run my older tests written in JUnit?

Any thoughts are welcome.

https://github.com/LemonadeLabInc/android-testng and https://github.com/cbeust/testng/issues/733 could be a partial answer.

From android-testng project:

This is a minimal implementation of an Android Instrumentation executing unit tests based on TestNG (the best testing framework for Java).
