1. 数据供给器

用来提供参数和结果，使用 @dataProvider 标注来指定使用哪个数据供给器方法。例如检测app升级数据是否符合预期，addProviderAppUpdateData()提供测试的参数和结果。testAppUpdateData()检测appUpdateData()返回的结果是否和给定的预期结果相等，即如果$appId='apple_3.3.2_117', $result=['status' => 0, 'isIOS' => false], 则$data中如果含有['status' => 0, 'isIOS' => false], 则断言成功。建议在数据提供器，逐个用字符串键名对其命名，这样在断言失败的时候将输出失败的名称，更容易定位问题。

示例代码：

<?php
  namespace Tests\Unit;

  use App\Services\ClientService;
  use Tests\TestCase;

  class ClientServiceTest extends TestCase
  {
    /**
     * @dataProvider addProviderAppUpdateData
     *
     * @param $appId
     * @param $result
     */
    public function testAppUpdateData($appId, $result)
    {
      $data = (new ClientService($appId))->appUpdateData();

      $this->assertTrue(count(array_intersect_assoc($data, $result)) == count($result));
    }

    public function addProviderAppUpdateData()
    {
      return [
        'null'         => [null, ['status' => 0, 'isIOS' => false, 'latest_version' => 'V']],
        'error app id'     => ['sdas123123', ['status' => 0, 'isIOS' => false, 'latest_version' => 'V']],
        'android force update' => ['bx7_3.3.5_120', ['status' => 0, 'isIOS' => false]],
        'ios force update'   => ['apple_3.3.2_117', ['status' => 1, 'isIOS' => true]],
        'android soft update' => ['sanxing_3.3.2_117', ['status' => 2, 'isIOS' => false]],
        'ios soft update'   => ['apple_3.3.3_118', ['status' => 2, 'isIOS' => true]],
        'android normal'    => ['fhqd_3.3.6_121', ['status' => 1, 'isIOS' => false]],
        'ios normal'      => ['apple_3.3.5_120', ['status' => 1, 'isIOS' => true]],
        'h5'          => ['h5_3.3.3', ['status' => 1, 'isIOS' => false]]
      ];
    }
  }

断言成功结果：

2. 断言方法

常用有assertTrue(), assertFalse(), assertNull(), assertEquals(), assertThat()。

assertThat()自定义断言。常用的约束有isNull()、isTrue()、isFalse()、isInstanceOf()；常用的组合约束logicalOr()、logicalAnd()。例如检测返回的结果是否是null或ApiApp类。

示例代码：

<?php
  namespace Tests\Unit;

  use App\Models\ApiApp;
  use App\Services\SystemConfigService;
  use Tests\TestCase;

  class SystemConfigServiceTest extends TestCase
  {
    /**
     * @dataProvider additionProviderGetLatestUpdateAppApi
     *
     * @param $appType
     */
    public function testGetLatestUpdateAppApi($appType)
    {
      $result = SystemConfigService::getLatestUpdateAppApi($appType);
      $this->assertThat($result, $this->logicalOr($this->isNull(), $this->isInstanceOf(ApiApp::class)));
    }

    public function additionProviderGetLatestUpdateAppApi()
    {
      return [
        'apple'  => [1],
        'android' => [2],
        'null'  => [9999]
      ];
    }
  }
