# This module tests Bugzilla/Search.pm. It uses various constants
# that are in Bugzilla::Test::Search::Constants, in xt/lib/.
#
# It does this by:
# 1) Creating a bunch of field values. Each field value is
#    randomly named and fully unique.
# 2) Creating a bunch of bugs that use those unique field
#    values. Each bug has different characteristics--see
#    the comment above the NUM_BUGS constant for a description
#    of each bug.
# 3) Running searches using the combination of every search operator against
#    every field. The tests that we run are described by the TESTS constant.
#    Some of the operator/field combinations are known to be broken--
#    these are listed in the KNOWN_BROKEN constant.
# 4) For each search, we make sure that certain bugs are contained in
#    the search, and certain other bugs are not contained in the search.
#    The code for the operator/field tests is mostly in
#    Bugzilla::Test::Search::FieldTest.
# 5) After testing each operator/field combination's functionality, we
#    do additional tests to make sure that there are no SQL injections
#    possible via any operator/field combination. The code for the
#    SQL Injection tests is in Bugzilla::Test::Search::InjectionTest.
#
# Generally, the only way that you should modify the behavior of this
# script is by modifying the constants.
