+Running unit tests
+==================
+
+Go to the SemanticScuttle main directory and run
+ $ php tests/AllTests.php
+or
+ $ phpunit tests/AllTests.php
+also remember the --verbose parameter to PHPUnit.
+
+If you want to run a specific test class only:
+ $ phpunit tests/BookmarksTest.php
+
+If you need to test one method only:
+ $ phpunit --filter BookmarkTest::testUnificationOfBookmarks tests/BookmarkTest.php
+
+
+Caveats
+-------
+Having debugging enabled and database driver "mysql4" activated
+will lead to failing tests because of FOUND_ROWS() usage, which
+does not work nicely with database debugging.
