Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
1 | <?php |
||
3 | class InsertTest extends BridgeTestCase |
||
4 | { |
||
5 | public function testLastInsertedId() |
||
6 | { |
||
7 | $this->assertEquals(0, $this->bridge->insertId()); |
||
8 | |||
9 | $this->bridge->query('INSERT INTO test_table VALUES (100, "test insert")'); |
||
10 | $this->assertEquals(100, $this->bridge->insertId()); |
||
11 | |||
12 | $this->bridge->query('INSERT INTO test_table (testfield) VALUES ("test insert")'); |
||
13 | $this->assertEquals(101, $this->bridge->insertId()); |
||
14 | } |
||
15 | } |
