So here’s a real simple example of how to use Providers in PHPUnit.
They’re very useful for running the exact same test multiple times but with different data being fed in.
| class ScoringTest extends TestCase | |
| { | |
| /** | |
| * Some Grades | |
| */ | |
| public static function all_grades_provider() | |
| { | |
| return [ | |
| [100.00], | |
| [50.00], | |
| [0], | |
| ]; | |
| } | |
| /** | |
| * Grade checks | |
| * @dataProvider all_grades_provider | |
| * @return void | |
| */ | |
| public function test_grade_score_is_correct ($grade) | |
| { | |
| // test our total is correct | |
| $this->assertEquals($grade, Score::someFunctionWhichAffectsGrade($grade)); | |
| } | |
| } |
