I'm sorry but I don't know how to fill in the tempate.

This is the problem:

[username]:[path to site]$ drush test-run location
Initialized Drupal 7.22 root directory at [path to site] [notice]
Initialized Drupal site default at sites/default [notice]
PHP Fatal error: Cannot redeclare class LocationTestCase in [path to site]/sites/all/modules/location/tests/location_testcase.test on line 188
Drush command terminated abnormally due to an unrecoverable error. [error]
Error: Cannot redeclare class LocationTestCase in [path to site]/sites/all/modules/location/tests/location_testcase.test, line 188
[username]:[path to site]$ cd sites/all/modules/location
[username]:[path to site]/sites/all/modules/location$ grep -r LocationTestCase *
tests/location_testcase.php:class LocationTestCase extends DrupalWebTestCase {
tests/location_cck2.test:class LocationCCK2Test extends LocationTestCase {
tests/google_geocoder.test:class LocationGoogleGeocoderTest extends LocationTestCase {

tests/cow.test:class CowInstanceTest extends LocationTestCase {
tests/earth.test:class LocationEarthTest extends LocationTestCase {
[username]:[path to site]/sites/all/modules/location$ gedit tests/location_testcase.php

The solution is obvious: change the name of one of those LocationTestCase classes - fixed and now my simpletest can run on the rest of the related modules.

NOTE: running Tests in Simplytest.me with location module only resulted in a fatal error
