Version History

  • 2025-01-22 : (tatu) Update wrt completed jackson-datatypes-collections conversion

Background

Currently in Jackson 2, most of modules including core and extensions have test suite shaped in following way.

  1. Co-existence of JUnit 4 and JUnit 5
  2. Exclude /failing tests using maven-surefire-plugin except jackson-databind module where we have "New failing test management using Jupiter extension" since 2.18 version.

Scope

Scope : changes to make

To keep up with Jackson 3 changes such as baseline version of JDK 17, it would be effective for consistency to implement following in order ....

  • Change 1 : Replace JUnit 4 with JUnit 5 usage
    • also, make use of something like DatabindTestUtil where needed (name to use maybe JacksonTestUtil or ModuleTestUtil
  • Change 2 : Replace use of src/test/java/.../failing package with Jackson's new failing test management and moving tests to new src/test/java/.../tofix package

Scope: target modules to apply

Note that modules to remove --or merge to other modules-- starting Jackson 3 will not be included.
