but when i try to run it in test environment it gives me following error

D:\sarasaves>rake thinking_sphinx:index RAILS_ENV=test
(in D:/sarasaves)
Generating Configuration to D:/sarasaves/config/test.sphinx.conf

using config file ‘D:/sarasaves/config/test.sphinx.conf’…
FATAL: no sources found in config file.
rake aborted!
The following command failed:
indexer --config D:/sarasaves/config/test.sphinx.conf --all

This could be caused by a PATH issue in the environment of
cron/passenger/etc. Y
our current PATH:
c:\program files\imagemagick-6.4.8-q8;C:\Program

You can set the path to your indexer and searchd binaries using the
