Lukasz Lenart created WW-5734:
---------------------------------
Summary: Run the JasperReports 7 plugin end-to-end on an embedded
Tomcat in its test suite
Key: WW-5734
URL: https://issues.apache.org/jira/browse/WW-5734
Project: Struts 2
Issue Type: Task
Components: Plugin - JasperReports
Reporter: Lukasz Lenart
Fix For: 7.4.0
{{struts2-jasperreports7-plugin}} shipped in 7.1.0 and has never been exercised
end-to-end: no sample application uses it, and its unit tests drive
{{JasperReport7Result}} against Spring's {{MockHttpServletResponse}}, which
does not model container behaviour. That is how WW-5731 (single-line CSV),
WW-5732 (case-sensitive format lookup) and WW-5733 (every export an empty
{{200}} on Tomcat) went unnoticed for four minor releases.
Adding the plugin to the showcase is not an option: JasperReports is LGPL (ASF
Category X) and the showcase WAR is part of the release assembly — the previous
showcase example was removed for exactly that reason in 2006.
Add an integration test to the plugin module instead: boot Struts on
{{tomcat-embed-core}} (test scope, so the LGPL dependency is not distributed),
configure a package extending {{jasperreports7-default}} with an action
returning a {{jasperReport7}} result over a compiled {{.jrxml}}, and assert
that a real HTTP request returns a non-empty body of the expected content type
for each bundled format. The test stays in the module's surefire run so CI
exercises the plugin on every build.
