I think I will try to do that.

Can you help me get the "specification" right? 

I see it as follows:

ui/batch/testrunner.rb, which is a subclass of 
ui/console/testrunner.rb. It emits same output as console runner to
stdout/stderr, but also writes one XML file for each test suite it has
to run. 

Naming convention and format of the XML is same as Ant JUnit runner (to
reuse Ant formatter / stylesheets).

XML files are placed in the directory specified in a mandatory argument
to the constructor. 

Alternatives: 

1. Output directory as an optional argument. I think, very few people
really want to write test reports to the root of the project during the
build, and therefore such default behavior would be counter-intuitive.
Better to fail cleanly with a good error message.

2. Emit output as YAML, and give YAML -> HTML conversion as part of the
package. That would be more interesting, but harder. Is there a good
YAML -> HTML converter?

3. Can probably package this feature as a mixin to anything that
subclasses TestRunnerUtils.

Brgds,
