NAME
SQL::Abstract::Test - Helper function for testing SQL::Abstract SYNOPSIS
use SQL::Abstract; use Test::More; use SQL::Abstract::Test import => [qw/ is_same_sql_bind is_same_sql is_same_bind eq_sql_bind eq_sql eq_bind /]; my ($sql, @bind) = SQL::Abstract->new->select(%args); is_same_sql_bind($given_sql, @given_bind, $expected_sql, @expected_bind, $test_msg); is_same_sql($given_sql, $expected_sql, $test_msg); is_same_bind(@given_bind, @expected_bind, $test_msg); my $is_same = eq_sql_bind($given_sql, @given_bind, $expected_sql, @expected_bind); my $sql_same = eq_sql($given_sql, $expected_sql); my $bind_same = eq_bind(@given_bind, @expected_bind); DESCRIPTION
This module is only intended for authors of tests on SQL::Abstract and related modules; it exports functions for comparing two SQL statements and their bound values. The SQL comparison is performed on abstract syntax, ignoring differences in spaces or in levels of parentheses. Therefore the tests will pass as long as the semantics is preserved, even if the surface syntax has changed. Disclaimer : the semantic equivalence handling is pretty limited. A lot of effort goes into distinguishing significant from non- significant parenthesis, including AND/OR operator associativity. Currently this module does not support commutativity and more intelligent transformations like Morgan laws, etc. For a good overview of what this test framework is capable of refer to "t/10test.t" FUNCTIONS
is_same_sql_bind is_same_sql_bind($given_sql, @given_bind, $expected_sql, @expected_bind, $test_msg); Compares given and expected pairs of "($sql, @bind)", and calls "ok" in Test::Builder on the result, with $test_msg as message. If the test fails, a detailed diagnostic is printed. For clients which use Test::More, this is the one of the three functions ("is_same_sql_bind", "is_same_sql", "is_same_bind") that needs to be imported. is_same_sql is_same_sql($given_sql, $expected_sql, $test_msg); Compares given and expected SQL statements, and calls "ok" in Test::Builder on the result, with $test_msg as message. If the test fails, a detailed diagnostic is printed. For clients which use Test::More, this is the one of the three functions ("is_same_sql_bind", "is_same_sql", "is_same_bind") that needs to be imported. is_same_bind is_same_bind(@given_bind, @expected_bind, $test_msg); Compares given and expected bind values, and calls "ok" in Test::Builder on the result, with $test_msg as message. If the test fails, a detailed diagnostic is printed. For clients which use Test::More, this is the one of the three functions ("is_same_sql_bind", "is_same_sql", "is_same_bind") that needs to be imported. eq_sql_bind my $is_same = eq_sql_bind($given_sql, @given_bind, $expected_sql, @expected_bind); Compares given and expected pairs of "($sql, @bind)". Similar to "is_same_sql_bind", but it just returns a boolean value and does not print diagnostics or talk to Test::Builder. eq_sql my $is_same = eq_sql($given_sql, $expected_sql); Compares the abstract syntax of two SQL statements. Similar to "is_same_sql", but it just returns a boolean value and does not print diagnostics or talk to Test::Builder. If the result is false, the global variable "$sql_differ" will contain the SQL portion where a difference was encountered; this is useful for printing diagnostics. eq_bind my $is_same = eq_sql(@given_bind, @expected_bind); Compares two lists of bind values, taking into account the fact that some of the values may be arrayrefs (see "bindtype" in SQL::Abstract). Similar to "is_same_bind", but it just returns a boolean value and does not print diagnostics or talk to Test::Builder. GLOBAL VARIABLES
$case_sensitive If true, SQL comparisons will be case-sensitive. Default is false; $parenthesis_significant If true, SQL comparison will preserve and report difference in nested parenthesis. Useful while testing "IN (( x ))" vs "IN ( x )". Defaults to false; $sql_differ When "eq_sql" returns false, the global variable $sql_differ contains the SQL portion where a difference was encountered. SEE ALSO
