我正在嘗試為如下所示的單晶代碼撰寫測驗代碼。
一季度。如何撰寫可以訪問資料庫的測驗代碼？
Q2。如何重構這些可測驗的代碼？
Q3。有什么方法可以撰寫測驗代碼而對生產代碼進行較少的更改嗎？
我需要你的幫助！
謝謝！！
示例生產代碼）
<?
class Sample_Model_Service_A
{
private $_result
private $_options
private $_someValue
public function __construct($params, $ids, $data) {
$this->_options = Sample_Model_Service_B::getOption($data);
}
private function setSomeValue() {
// some code shaping $_params to $someValue with $this->_options
$this->_someValue= $someValue;
}
// want to write test for this function
// changed this function's logic
private function setResult() {
// some code shaping $_someValue to $result
$this->_result = $result;
}
public function getter() {
retrn $this->_result;
}
}
?>
<?
class Sample_Model_Service_B
{
// get option from DB
public static function getOption($data) {
$dao = new Model_Dao_Option();
$option = $dao->getOption($data['id']);
return $option;
}
}
?>
到目前為止我的測驗代碼）
public function testsetResult()
{
// just make sure these variables are defined
$params = $ids = $data = [];
// try to make test for private function
$sample = new Sample_Model_Service_A($params, $ids, $data);
$reflection = new ReflectionClass($sample);
// get Method
$method = $reflection->getMethod('setresult');
$method->setAccessible(true);
// wondering how to get $result
$result = $method->invoke($sample);
// assert
$this->assertSame($result);
}
uj5u.com熱心網友回復：
嘲笑解決了我的問題。
示例代碼）
/**
* @dataProvider sampleProvider
*/
public function testsetResult($sampleData)
{
// mock Sample_Model_Service_B
$mockSample_Model_Service_B = Mockery::mock('alias:' . Sample_Model_Service_B::class);
$mockSample_Model_Service_B->shouldReceive('getOption')->andReturn($sampleData['option']);
$sample = new Sample_Model_Service_A($sampleData['params'], $sampleData['ids'], $sampleData['data']);
$sample->setResult();
$result = $sample->getter();
// assert
$this->assertSame($result, $sampleData['result']);
}
