The junit5-migration-maven
project demonstrates how to execute tests based on JUnit 5
using Maven. In addition, it showcases that existing JUnit 4 based tests can be executed
in the same test suite as JUnit Jupiter based tests or any other tests supported on
the JUnit Platform.
This sample project does not aim to demonstrate how to use the JUnit Jupiter APIs. For detailed information on the JUnit Jupiter programming and extension models, please consult the User Guide.
Please note that this project uses the Maven Wrapper.
Thus, to ensure that the correct version of Maven is used, invoke mvnw
instead of mvn
.
Invoking mvnw clean test
from the command line will execute all tests in the test source
folder that follow one of following patterns: Test*
, *Test
, *Tests
, or *TestCase
.
Note that Surefire's default naming patterns
have been overridden in the pom.xml
file. Surefire's execution of
the sample tests should result in output similar to the following:
