JUnit 5 provides a way out of the box.
JUnit 5 = JUnit Platform + JUnit Jupiter + JUnit Vintage
Each one is a distinct project and using all of them allows to compile and execute JUnit 4 and JUnit 5 tests in a same project.
JUnit Jupiter is the combination of the new programming model and extension model for writing tests and extensions in JUnit 5.
JUnit Vintage provides a TestEngine for running JUnit 3 and JUnit 4 based tests on the platform.
The JUnit Platform serves as a foundation for launching testing frameworks on the JVM
Update : from Maven Surefire 2.22.0
From the JUnit 5 documentation :
Starting with version
2.22.0
, Maven Surefire provides native support for executing tests on the JUnit Platform.
So the configuration is much simpler.
Note that the junit-4
api dependency is optional as the engine
dependencies that are now required already pull a default api
version (it is the case for both junit 4 and 5).
Here is a sample pom.xml
.

Old way : for Maven Surefire below 2.22.0
Here is the minimal configuration to use with Maven to configure the project to compile and run both JUnit4 and JUnit5 tests :

Now mvn test
compiles and runs both JUnit 4 and JUnit 5 tests.
Note 1 : the junit-vintage-engine
(4.12.1
) and the junit
(4.12
) dependencies don't specify the same exact version.
This is not an issue at all as :
their release are not related between them
junit-vintage-engine
is designed to run any JUnit 3 or 4 tests.
Note 2 : maven-surefire-plugin with the 2.19.1
version matters whatever you want to compile JUnit 5 test classes or both JUnit 4 and JUnit 5 test classes.
Next version of the plugin causes indeed some exceptions during JUnit 5 tests execution but the 2.22.0
that at last solves the issue (see the first part of the answer : "Update : from Maven Surefire 2.22.0").

The efficiency of test automation largely depends on how well the ‘functionality under test’ is behaving against different input combinations. For instance, an email provider would have to verify different screens like login, sign-up, etc., by supplying different input values to the scenarios. However, the effort involved in maintaining the test code rises significantly with new functionalities in the web product.
One of the major hurdles that web-developers, as well as app developers, the face is ‘Testing their website/app’ across different browsers. The testing mechanism is also called as ‘Cross Browser Testing’. There are so many browsers and browser versions (Google Chrome, Mozilla Firefox, Internet Explorer, Microsoft Edge, Opera, Yandex, etc.), numerous ways in which your website/app can be accessed (via desktop, smartphones, tablets, etc.) and numerous operating systems (Windows, MacOS, Linux, Android, iOS, etc.) which might be used to access your website.
One of the most common test automation challenges is how do we modify the request headers in Selenium WebDriver. As an automation tester, you would come across this challenge for any programming language, including Java. Before coming to the solution, we need to understand the problem statement better and arrive at different possibilities to modify the header request in Java while working with Selenium WebDriver Tutorial.
Parallel test execution with Selenium is one of the major factors that can affect the test execution speed. Serial execution in Selenium can be effective only if the tests have to be run on a small number of browser and OS combinations. Therefore, parallel execution should be leveraged at the early stages of QA testing to expedite test execution rapidly.
Automation testing has become an absolute necessity in an agile and fast-paced business environment with an immense focus on accelerated time to market. However, as far as automation is concerned, Selenium automation testing still reaps the maximum benefits in terms of test coverage and browser coverage.
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:
