Konstantin Boudnik commented on ZOOKEEPER-725:
----------------------------------------------
bq. Cos, what's best practice for passing information into a test? In this case
say we are passing the server port information into the client tests. How best
to do this? jvm parameters (-Dzk.server.host1=host1:1234)? parameterized junit
tests seem overkill for just a single test, no?
Unfortunately, JUnit (at least currently) isn't very flexible in this regard.
TestNG is a way more advanced in this regard, but their sameVM model of test
execution makes test development a more cumbersome task. However, the tests are
coming out are more elegant and correct in comparison with JUnit approach of
killing a VM after a test case execution. We already had an exercise with
TestNG and you know what I meant :)
Possible ways to parametrize tests in JUnit are:
- sys. props in the command line/runtime as you have pointed out above
- sys. props set in a properties file
- using Fixtures aka @Before and @After methods. Using fixtures one can develop
an elaborate setup method which might set certain states before a test case is
started. The data for setting such state might be read from a file containing a
set of parameters per line. Or it might be more "sophisticated" XML file. Or a
configuration factory. Or something else...
Apparently, first two approaches are inferior to the latter way. However, it
requires more ground work. Benefits are numerous. Not the least one is a
significant simplification of build process.
