PHPUnit的數據提供程序超出範圍

Question

類我測試：

class Calculate { 
    public $x; 
    public $y; 

    public function __construct($x, $y) { 
     $this->x = $x; 
     $this->y = $y; 
    } 

    public function add(): int { 
     return $this->x + $this->y; 
    } 
} 

我的測試代碼：

use PHPUnit\Framework\TestCase; 

class CalculateTest extends TestCase { 

    public function additionProvider() { 
     return [ 
      [1, 2], 
      [5, 8], 
      [-1, 10], 
      [66, 3], 
      [9, 4] 
     ]; 
    } 

    /** 
    * @dataProvider additionProvider 
    */ 
    public function testGetIsOk($x, $y): Calculate { 
     $c = new Calculate($x, $y); 
     var_dump($c); 
     $this->assertEquals($x, $c->x); 
     $this->assertEquals($y, $c->y); 

     return $c; 
    } 

    /** 
    * @depends testGetIsOk 
    */ 
    public function testAddIsNormal(Calculate $c):void { 
     $this->assertEquals($c->x + $c->y, $c->add()); 
    } 



} 

有dataProvider中的5個元素，但測試結果表明，6號測試是錯誤的。

PHPUnit 6.3.0 by Sebastian Bergmann and contributors.

.....E 6/6 (100%)

Time: 97 ms, Memory: 8.00MB

There was 1 error:

1) CalculateTest::testAddIsNormal TypeError: Argument 1 passed to CalculateTest::testAddIsNormal() must be an inst ance of Calculate, null given

謝謝。

好的，我在github上檢查了這個問題，最後我知道我無法將從數據提供者獲取數據的測試結果傳遞給另一個測試。 有它：https://github.com/sebastianbergmann/phpunit/issues/611
