php 7.2.9_1
laravel 5.6.2
nginx 1.15.2
mac 10.13.6 ^_^
phpstorm 2017.1.2
我正在使用laravel学习phpunit，我遵循phpunit的文档。当我阅读@dataprovider时，我想尝试一下。所以我在Mac中键入代码，遇到错误。我无法从日志中读取任何有用的消息。有人可以告诉我我在哪里出错？
namepsace Tests\Feature
use Tests\TestCase
class ConventionTest extends TestCase{
/**
* @dataProvider additionProvider
*/
public function testParent($a, $b, $expected)
{
$this->assertEquals($expected, $a + $b);
}
public function additionProvider(){
return [
'adding zeros' => [0, 0, 0],
'zero plus one' => [0, 1, 1],
'one plus zero' => [1, 0, 1],
'one plus one' => [1, 1, 3]
];
}
}
我跑过phpunit tests/Feature/ConventionTest.php --filter testParent的地方是结果：
PHPUnit 7.3.2 by Sebastian Bergmann and contributors.
