如何为执行存储过程的 php function 编写单元测试？

Question

public function get(): array
    {

        $val = [
            '@a' =>  $this->c,
            '@b'   => (int)$this->issucess
        ];
        try {
            return $this->db->Execute($this->spName, $val);
        } catch (\Exception $e) {
           
        }
    }

How do I write a unit test for such functions which are executing stored procedure while returning in PHP? Is there any example for it in PHPUnit ?

Answer 1

If you test FUNCTION, NOT PROCEDURE - create db mock

$testParams = [
  '@a' => 'value',
  '@b' => 'value'
];
//stub procedure results
$testProcedureResult = [];
$dbMock = Mockery::mock(Database::class);
$dbMock->method('Execute')
  ->once()
  ->with('procedure', $testParams)
  ->willReturn($testProcedureResult);

$service = new YourTestedClass($dbMock);
//other service configuration..
$this->assertSame($testProcedureResult, $service->get());
