Had the same message. I had to remove the Run/Debug configuration.
In my case, I ran the unit test as a local test before. After that I moved my test to the androidTest package and tried to run it again. Android Studio remembered the last run configuration so it tried to run it again as a local unit test which produced the same error.
After removing the config and running the test again it generated a new configuration and worked.

While there is a huge demand and need to run Selenium Test Automation, the experts always suggest not to automate every possible test. Exhaustive Testing is not possible, and Automating everything is not sustainable.
When we talk about programming in the modern tech world, Java instantly comes to our mind. After all, it is considered as one of the most versatile programming languages. Looking back on its history, Java has always had an extraordinary position in a back-end developer’s heart. A majority of developers enjoy Java due to its platform independency, security, ease of use, variety of accessible resources, and several other essential features. These traits appreciably contributed to the popularity of Java as a programming language – as of 2018, there were seven million or more Java developers globally.
When you start your journey as an automation tester, then mistakes are bound to happen. They may also happen if you are up in a race to automated website testing without exploring the impact of your Selenium test automation scripts in depth. And while it is good to learn from your mistakes, it is always better to be preventive by learning from others.

The primary intent of Selenium test automation is to expedite the testing process. In the majority of the cases, automation tests using Selenium perform exceptionally better than the manual counterparts. However, there might be possibilities to speed up Selenium tests using Selenium test automation best practices to its truest potential. I have come across umpteen cases in my career where there was potential to speed up selenium tests.
LambdaTest also has a detailed JUnit tutorial explaining its features, importance, advanced use cases, best practices, and more to help you get started with running your automation testing scripts.
Here are the detailed JUnit testing chapters to help you get started:
