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.

24 Testing Scenarios you should not automate with Selenium

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.

Top 10 Java Unit Testing Frameworks for 2021

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.

14 Mistakes I Did That You Should Avoid As A Newbie Automation Tester

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.

How To Speed Up Selenium Test Cases Execution?

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.

JUnit Tutorial:

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.

JUnit Tutorial Chapters:

Here are the detailed JUnit testing chapters to help you get started:

  • Importance of Unit testing - Learn why Unit testing is essential during the development phase to identify bugs and errors.
  • Top Java Unit testing frameworks - Here are the upcoming JUnit automation testing frameworks that you can use in 2023 to boost your unit testing.
  • What is the JUnit framework
  • Why is JUnit testing important - Learn the importance and numerous benefits of using the JUnit testing framework.
  • Features of JUnit - Learn about the numerous features of JUnit and why developers prefer it.
  • JUnit 5 vs. JUnit 4: Differences - Here is a complete comparison between JUnit 5 and JUnit 4 testing frameworks.
  • Setting up the JUnit environment - Learn how to set up your JUnit testing environment.
  • Getting started with JUnit testing - After successfully setting up your JUnit environment, this chapter will help you get started with JUnit testing in no time.
  • Parallel testing with JUnit - Parallel Testing can be used to reduce test execution time and improve test efficiency. Learn how to perform parallel testing with JUnit.
  • Annotations in JUnit - When writing automation scripts with JUnit, we can use JUnit annotations to specify the type of methods in our test code. This helps us identify those methods when we run JUnit tests using Selenium WebDriver. Learn in detail what annotations are in JUnit.
  • Assertions in JUnit - Assertions are used to validate or test that the result of an action/functionality is the same as expected. Learn in detail what assertions are and how to use them while performing JUnit testing.
  • Parameterization in JUnit - Parameterized Test enables you to run the same automated test scripts with different variables. By collecting data on each method's test parameters, you can minimize time spent on writing tests. Learn how to use parameterization in JUnit.
  • Nested Tests In JUnit 5 - A nested class is a non-static class contained within another class in a hierarchical structure. It can share the state and setup of the outer class. Learn about nested annotations in JUnit 5 with examples.
  • Best practices for JUnit testing - Learn about the best practices, such as always testing key methods and classes, integrating JUnit tests with your build, and more to get the best possible results.
  • Advanced Use Cases for JUnit testing - Take a deep dive into the advanced use cases, such as how to run JUnit tests in Jupiter, how to use JUnit 5 Mockito for Unit testing, and more for JUnit testing.
