[undertow-dev] Writing tests for HTTP handlers

[Tomaž Cerar]

You could use DefaultServer junit runner for your tests.

Same "framework" that undertow tests are written with.

for example see
https://github.com/undertow-io/undertow/blob/master/core/src/test/java/io/undertow/server/handlers/file/FileHandlerTestCase.java

or pretty much any other test.
