[Geoserver-devel] Unit Testing Concurrency Issue

Is there a standard practice for unit testing concurrency issues in
GeoServer? I found an issue in
org.geoserver.wms.featureinfo.HTMLFeatureInfoOutputFormat.getTemplate that
could cause the wrong content template to be used if GeoServer is processing
multiple WMS GetFeatureInfo requests with HTML output. This could result in
incorrect output or even errors if the template that gets loaded does not
work with the layer that is being processed.

Hi Steve,
we don't really have much, the few cases I think we used a executor
submitting
a bunch of callables into it, but trying to still keep the test running for
a short
amount of time, e.g.:

https://github.com/geoserver/geoserver/blob/master/src/extension/control-flow/src/test/java/org/geoserver/flow/NestedRequestSentinelTest.java#L45
https://github.com/geoserver/geoserver/blob/master/src/main/src/test/java/org/geoserver/security/filter/GeoServerBasicAuthenticationFilterTest.java#L42

Cheers
Andrea
