Steve Loughran commented on HADOOP-6725:
----------------------------------------
I am +1 for this and anything else which tests the webapps. HtmlUnit is the
best in-java web app test framework I know of; I use it on my code. Right now
we have some tests for a servlet or two, but nothing looks at the JSP/webapp
content, so things like HADOOP-6461 aren't being picked up
# HtmlUnit is looking at moving to the ASF; support from the Hadoop team would
be welcome
# JSF unit is separate, it's testing Java Server Faces. HtmlUnit will happily
test JSP and pages with javascript in them
# For ease of testing, HTML elements need IDs. HADOOP-5388 covers this. The
tags and the tests can go hand in hand.
# I can help with setting up the test framework, try and get Marc Guillemot to
review the design too.
I would really benefit from some HtmlUnit tests that could be run against a
live cluster rather than just a miniDFS and miniMR cluster; the tests could be
something standalone/redistributable that could be given the URL of a NN, DN,
JT or TT and scan through all the expected pages. Having sequences to submit
jobs and other actions then becomes further work.

> Reporter: Jakob Homan
> Priority: Minor

> HtmlUnit (http://htmlunit.sourceforge.net/) looks like it may be a good tool
> to help unit testing and evaluating our various webpages throughout the
> project. Currently this is done only occasionally in the code (usually falls
> to being a manual test during release cycles), and when it is done, usually
> the code to parse the webpage, etc. is re-written each time. The framework
> is Apache licensed, so including it won't be an issue. If it's found to be
> useful, new JIRAs for HDFS and MR should be opened.
