#
# This constant contains operators as keys, which point to hashes. The hashes
# have field names as keys. Each field name points to a hash describing
# how that field/operator combination is broken. The "contains"
# array specifies that that particular "contains" test is expected
# to fail. If "search" is set to 1, then we expect the creation of the
# Bugzilla::Search object to fail.
#
# To allow handling custom fields, you can also use the field type as a key
# instead of the field name. Specifying explicit field names always overrides
# specifying a field type.
#
# Sometimes the operators have multiple tests, and one of them works
# while the other fails. In this case, we have a special override for
# "operator-value", which uniquely identifies tests.

# Tests #

# The basic format of this is a hashref, where the keys are operators,
# and each operator has an arrayref of tests that it runs. The tests
# are hashrefs, with the following possible keys:
#
# contains: This is a list of bug numbers that the search is expected
#           to contain. (This is bug numbers, like 1,2,3, not the bug
#           ids. For a description of each bug number, see NUM_BUGS.)
#           Any bug not listed in "contains" must *not* show up in the
#           search result.
# value: The value that you're searching for. There are certain special
#        codes that will be replaced with bug values when the tests are
#        run. In these examples below, "#" indicates a bug number:
#
#        <#> - The field value for this bug.
#
#              For any operator that has the string "word" in it, this is
#              *all* the values for the current field from the numbered bug,
#              joined by a space.
#
#              If the operator has the string "substr" in it, then we
#              take a substring of the value (for single-value searches)
#              or we take a substring of each value and join them (for
#              multi-value "word" searches). The length of the substring
#              is determined by the SUBSTR_SIZE constants above.)
#
#              For other operators, this just becomes the first value from
#              the field for the numbered bug.
#
#              So, if we were running the "equals" test and checking the
#              cc field, <1> would become the login name of the first cc on
#              Bug 1. If we did an "anywords" search test, it would become
#              a space-separated string of the login names of all the ccs
#              on Bug 1. If we did an "anywordssubstr" search test, it would
#              become a space-separated string of the first few characters
#              of each CC's login name on Bug 1.
#              
#        <#-id> - The bug id of the numbered bug.
#        <#-reporter> - The login name of the numbered bug's reporter.
#        <#-delta> - The delta_ts of the numbered bug.
#
# escape: If true, we will call quotemeta() on the value immediately
#         before passing it to Search.pm.
#
# transform: A function to call on any field value before inserting
#            it for a <#> replacement. The transformation function
#            gets all of the bug's values for the field as its arguments.
# if_equal: This allows you to override "contains" for the case where
#           the transformed value (from calling the "transform" function)
#           is equal to the original value.
#
# override: This allows you to override "contains" and "values" for
#           certain fields.
