The original Ant JUnit reporter produced test durations via Double.toString(),
supporting arbitrary precisions, and the de-facto schema declared them
as xs:decimal.
Sadly, the now popular Maven Surefire reporter limited the duration to
millisecond precision, and hard-coded this into its schema as SUREFIRE_TIME:
https://issues.apache.org/jira/browse/SUREFIRE-1533
Unfortunately this definition spread into tools such as the Jenkins xUnit
plugin, which relies on the schema provided by Maven Surefire:
https://issues.jenkins.io/browse/JENKINS-52152
As a result, anything that produces higher precision results will not
validate in the Jenkins xUnit plugin.
Other test frameworks have bitten the bullet and reduced their precision
correspondingly, e.g.:
https://github.com/catchorg/Catch2/issues/2221https://github.com/catchorg/Catch2/commit/581c46249acf8389e9
We follow suit, and our JUnit XML output now validates against both
the Jenkins JUnit and xUnit plugins, as well as the original Apache
Ant de-facto schema.
