+.Aligning dependency versions
+====
+To ensure that all JUnit artifacts are compatible with each other, their versions should
+be aligned.
+If you rely on <<running-tests-build-spring-boot, Spring Boot>> for dependency management,
+please see the corresponding section.
+Otherwise, instead of managing individual versions of the JUnit artifacts, it is
+recommended to apply the <<dependency-metadata-junit-bom, BOM>> to your project.
+Please refer to the corresponding sections for <<running-tests-build-maven-bom, Maven>> or
+<<running-tests-build-gradle-bom, Gradle>>.
