Preconditions:
 * Properly installed apache-jmeter-2.9

To run stress tests simply run jmeter and open SearchResourcesStressTest.jmx or SearchCollectionStressTest.jmx file.
By default tests hit https://infona.pl/ instance with safe amount of user (10 users in 5 s ramp-up time, so 2 users per second).

Tests use following files:
 * data/logins.csv - contains credentials for existing portal users
 * data/resource_phrases.csv - list of phrases used for search resource testing
 * data/collection_phrases.csv - list of phrases used for search collection testing

Before you run tests edit data/logins.csv file to provide proper authorization data for users, and
tune up test parameters:
1. To increase amount of concurrent requests open "Thread Group" tab and modify
   "Number of threads (users)" and "Ramp-Up Period" fields.
2. To change tested environment open "Thread Group" -> "Simple Controller" -> "Server configuration" tab and
   change proper variables (SERVER, PORT, CONTEXT_PATH, PROTOCOL. For default localhost instance it will be something like:
   localhost, 8443, portal, https respectively)

Test plans based on ticket 1581.


Important notes!

Tests fail if user can not log into portal.
Tests *not* fail if:
 - search engine returns no results (this is expected)
 - resource does not contain author
