Steve Loughran commented on HADOOP-4059:
----------------------------------------
I hadnt looked at that before..yes, there is some good code there to drive it
off XML files not java code. But the current tests dont run the scripts to
start/stop cluster services, just the FS operations. I need tests for the
services. testCLI seems a good starting point for some of this.
Incidentally, I've worked on past projects where the XML Files generated a
different test case for junit; there is a trick to doing this (static TestSuite
method), which then results in separate test reports for every command in the
file. We could use this trick again.

> Project: Hadoop Core

> Hadoop has lots of tests that start clusters, but I don't see any that test
> the command line scripts working. Which means that changes to the scripts and
> the code behind them may not get picked up rapidly, and regressions won't get
> picked up by Hudson and apportioned to the specific patches.
> Propose:
> * an abstract test case that can exec scripts on startup; wait for them to
> finish, kill them if they take too long
> * test cases for every service (namenode, tasktracker, datanode, etc)
> * tests that try invalid commands, -help options
> * tests that start the services, assert that they are live, and shut them down
