Logging configuration is difficult for running tests
----------------------------------------------------
Key: OPENJPA-1557
URL: https://issues.apache.org/jira/browse/OPENJPA-1557
Project: OpenJPA
Issue Type: Improvement
Affects Versions: 2.0.0-beta2, 1.2.2
Reporter: Craig L Russell
Assignee: Craig L Russell
Fix For: 1.3.0, 2.0.0
Logging is difficult to configure and is incorrectly documented for running
tests.
There is a system property that can be set on the command line when running
tests using surefire: openjpa.loglevel. This property, set via
-Dopenjpa.loglevel, is used in the pom.xml to send logging properties to the
runtime. The simple case works, e.g. -Dopenjpa.loglevel=error. This affects
enhancement and the test runtime to report only errors.
However, setting this property also results in warnings:
enhance.all.entities:
[echo] running enhancer
12 WARN [main] openjpa.Runtime - The configuration property named
"openjpa.loglevel" was not recognized and will be ignored, although the name
closely matches a valid property called "openjpa.Log".
2 WARN [main] openjpa.Runtime - The configuration property named
"openjpa.loglevel" was not recognized and will be ignored, although the name
closely matches a valid property called "openjpa.Log".
This is because the property is both passed to the runtime and also used to
configure the log level via the surefire plugin (the relevant part of the
pom.xml follows):
<property>
<name>openjpa.Log</name>
<value>DefaultLevel=${openjpa.loglevel}</value>
</property>
Via "property injection" it's also possible to set any number of other log
properties using this mechanism, although it's a bit odd. Just concatenate the
extra properties after the level. For example,
mvn test -Dopenjpa.loglevel=trace,file=openjpa.log,Runtime=info
This will set the default log level to trace, send the log output to the file
openjpa.log, and set the Runtime log level to info.
The surefire plugin effectively disables the openjpa.Log so the user cannot use
this property.
The warning can be removed by changing the PersistenceTestCase.createNamedEMF:
Map map = new HashMap(System.getProperties());
map.remove("openjpa.level");
But the enhancer doesn't go through this path.
Before I change the online documentation I'd like to see if anyone else has any
ideas how to make this easier.
