98 | =head1 NAME |
99 | |
100 | DBIC::SqlMakerTest - Helper package for testing sql_maker component of DBIC |
101 | |
102 | =head1 SYNOPSIS |
103 | |
104 | use Test::More; |
105 | use DBIC::SqlMakerTest; |
106 | |
107 | my ($sql, @bind) = $schema->storage->sql_maker->select(%args); |
108 | is_same_sql_bind( |
109 | $sql, \@bind, |
110 | $expected_sql, \@expected_bind, |
111 | 'foo bar works' |
112 | ); |
113 | |
114 | =head1 DESCRIPTION |
115 | |
116 | Exports functions that can be used to compare generated SQL and bind values. |
117 | |
118 | If L<SQL::Abstract::Test> (packaged in L<SQL::Abstract> versions 1.50 and |
119 | above) is available, then it is used to perform the comparisons (all functions |
120 | are delegated to id). Otherwise uses simple string comparison for the SQL |
121 | statements and simple L<Data::Dumper>-like recursive stringification for |
122 | comparison of bind values. |
123 | |
124 | |
125 | =head1 FUNCTIONS |
126 | |
127 | =head2 is_same_sql_bind |
128 | |
129 | is_same_sql_bind( |
130 | $given_sql, \@given_bind, |
131 | $expected_sql, \@expected_bind, |
132 | $test_msg |
133 | ); |
134 | |
135 | Compares given and expected pairs of C<($sql, \@bind)>, and calls |
136 | L<Test::Builder/ok> on the result, with C<$test_msg> as message. |
137 | |
138 | =head2 eq_sql |
139 | |
140 | my $is_same = eq_sql($given_sql, $expected_sql); |
141 | |
142 | Compares the two SQL statements. Returns true IFF they are equivalent. |
143 | |
144 | =head2 eq_bind |
145 | |
146 | my $is_same = eq_sql(\@given_bind, \@expected_bind); |
147 | |
148 | Compares two lists of bind values. Returns true IFF their values are the same. |
