Christian Stein commented on SUREFIRE-1546:
-------------------------------------------
Display names are not intended and are not even able to be used reliably as
suggested by [~dantran] – see this
[TestIdentifier.html#getDisplayName()|https://junit.org/junit5/docs/current/api/org/junit/platform/launcher/TestIdentifier.html#getDisplayName()]
documentation:
{quote}A _display name_ is a human-readable name for a test or container that
is typically used for test reporting in IDEs and build tools. Display names may
contain spaces, special characters, and emoji, and the format may be customized
by
[{{TestEngines}}|https://junit.org/junit5/docs/current/api/org/junit/platform/engine/TestEngine.html]
or potentially by end users as well. Consequently, display names should never
be parsed; rather, they should be used for display purposes only.
{quote}
Using display name in place like
{{<testcase name="test case using displayName" classname="class name using
displayName" time="0"/>}}
will lead to problems. Users may provide a single shard display name for all
containers and tests... or down-stream tools might rely on having "real" Java
class names and method names here.
{quote}We plan to print display name in std-out and std-err.
{quote}
This is the option chosen by the JUnit Team. It attaches the arbitrary display
name to the report entry of the originating source. So, down-stream tools can
extract from here. Find the sources of our soon released XML writer at GitHub,
and the lines related to new attributes (like unique-id and displayName) here:
https://github.com/junit-team/junit5/blob/master/junit-platform-reporting/src/main/java/org/junit/platform/reporting/legacy/xml/XmlReportWriter.java#L279-L280
I strongly suggest to *not* alter the XML format used by Ant/Surefire in an
incompatible manner.

> Project: Maven Surefire
> Issue Type: Bug
> Components: JUnit 5.x support
> Affects Versions: 2.22.0

> JUnit 5 runner should respect the test @DisplayName instead of displaying the
> classname if any is defined. Seems last release doesn't support that feature
> of JUnit 5 making the console output and reports not the expected ones.
