All,
I’d like to propose adding an integration test layer to the Tomcat source
tree that validates Tomcat behavior when deployed behind httpd as a reverse
proxy.
Tomcat’s documentation treats reverse proxy operation as a distinct
configuration surface (e.g. utilizing RemoteIpValve and SSLValve). These
are paths for which having automated regression coverage would reduce risk
in future changes and test that everything's working as expected flawlessly.
I’m proposing a new directory in the Tomcat repo (e.g. integration/ ) that
contains the entire implementation:
1. A Java-based harness to provision a test environment.
- Creates an isolated CATALINA_BASE under output/
- Writes templated Tomcat and httpd configs for each scenario per
proxy mode
- Starts/stops Tomcat and httpd as external processes
- Waits for readiness and captures logs into a dedicated output
direcotry
2. A minimal test web application used as a stable assertion target
3. A set of JUnit integration tests that send requests to httpd and
validate the results as seen by Tomcat testing the documented proxy
configuration behaviors.
This would be added as Ant target(s), separate from the default 'ant test'
workflow, e.g. 'ant integration-httpd'.
I would appreciate your feedback on this.
+1 for all of that, particularly as long as it:
1. Is completely optional
2. Doesn't break anything already working
You said you would do this as completely new ant targets, so I say "go
for it".
We'll all want to know how to use it for release testing, of course, but
you can tell us when it's ready. Remember that we are all on different
environments: I'm primarily on Mac, Mark straddles the fence of
Windows/Mac, Konstantin is primarily Windows, Rémy is Linux (and I
assume you as a Red Hatter are also on Linux), and Rainer has a zoo of
*NIX environments on which to test.
If you want to go environment-by-environment, make sure to use the ant
support for doing things differently on each OS. For Mac, you can just
"fail with error message saying Mac isn't supported" for example, and
then we can add support later.
