What you can do in particular is to create a directory for tests to have the following structure: [module] + src/main/java/[com/foo/bar] + src/test/java/[com/foo/bar] The above structure will be recognized by Android Studio and your files underneath will be included into the module.

Unit Testing is a crucial step in software design and implementation. It not only improves the efficiency and effectiveness of the code, but it also makes the code more robust and reduces the regressions in future development and maintenance. In this tutorial, we’ll discuss a few best practices for unit testing in Java.
Unit Testing is a methodology of testing source code for its fitment of use in production. We start out writing unit tests by creating various test cases to verify the behaviors of an individual unit of source code. Then the complete test suite executes to catch the regressions, either in the implementation phase or while building packages for vari...
3.1. Source Code
It’s a good idea to keep the test classes separate from the main source code. So, they are developed, executed and maintained separately from the production code. Also, it avoids any possibility of running test code in the production environment. We can follow the steps of the build tools such as Maven and Gradle that look for src/main/testdirectory for test implementations.
3.2. Package Naming Convention
We should create a similar package structure in the src/main/testdirectory for test classes, this way improving the readability and maintainability of the test code. Simply put, the package of the test class should match the package of the source classwhose unit of source code it’ll test. For instance, if our Circle class exists in the com.baeldung.math package, the CircleTest class should also exist in the com.baeldung.math package under the src/main/testdirectory structure.
3.3. Test Case Naming Convention
The test names should be insightful, and users should understand the behavior and expectation of the test by just glancing at the name itself. For example, the name of our unit test was testCalculateArea, which is vague on any meaningful information about the test scenario and expectation. Therefore, we should name a test with the action and expectation such as testCalculateAreaWithGeneralDoubleValueRadiusThatReturnsAreaInDouble,testCalculateAreaWithLargeDoubleValueRadiusThatReturnsAreaAsInfi...
In this article, we explored some best practices of Unit Testing in Java. Following best practices can help in many aspects of software development.
Sep 10, 2023 · In software development, Java testing is akin to a gold standard. It ensures that each component of an application, no matter how minute, functions as intended. This guide will discuss unit testing for Java frameworks, offering examples and best practices to bolster your coding journey.
In this article we will take a look at some key best practices for defining Go and Java unit test naming conventions and test folder structures. We will also cover how Symflower can be configured to change your project’s conventions of naming and locating unit test files.
Apr 3, 2023 · Unit Testing involves testing each and every component of your code to see if they work as expected. It isolates each individual method of your code and performs tests on it. Unit tests helps make sure that your software is working as expected before releasing it.
Apr 10, 2021 · Under the test/java folder, create a package com.gerv.guev or whatever package name you already used in your project. Then create a file named MyStringUtilitiesTest.java . You may copy the contents of the class for now, I'll explain what it does along the way.

Mar 7, 2022 · In this article, you will learn how to write code which is easily testable and how to test it using a single tool: JUnit 5. Java Development Kit (JDK) version 8 or newer. JUnit 5.8.2 (though most versions of JUnit 5 should work). An IDE with JUnit integration is recommended, such as Eclipse, Intellij IDEA, Android Studio, NetBeans.
