Laravel测试类属性不持久

Question

我正在尝试设置一个sensorId属性，该属性将由我的功能测试中的每个方法使用。问题是它在测试之间并没有持续。

这是我的测试类：

class LogApiPostTest extends TestCase
{
    public $sensorId;

    public function setUp(): void
    {
        parent::setUp();

        $this->sensorId = 'SEN' . rand(10000000, 999999999);
    }

    public function test_creates_sensor()
    {
        $response = $this->post('/api/logs', $this->data([
            //
        ]));

        $response->assertStatus(200);
        $response->assertSeeText('Sensor created');
    }

    public function test_updates_sensor()
    {
        $response = $this->post('/api/logs', $this->data([
            //
        ]));

        $response->assertStatus(200);
        $response->assertSeeText('Sensor updated');
    }

    public function test_creates_car()
    {
        $response = $this->post('/api/logs', $this->data([
            'CarID' => 'B',
        ]));

        $response->assertStatus(200);
        $response->assertSeeText('Car created');
    }

    public function test_updates_car()
    {
        $response = $this->post('/api/logs', $this->data([
            'CarID' => 'B',
        ]));

        $response->assertStatus(200);
        $response->assertSeeText('Car updated');
    }

    public function test_is_unauthorized()
    {
        $response = $this->post('/api/logs', $this->data([
            'token_id' => 'thisShouldntWork',
        ]));

        $response->assertUnauthorized();
    }

    public function data($merge = [])
    {
        return array_merge([
            'token_id' => config('api.token'),
            'sensorID' => $this->sensorId,
            'CarID' => 'A',
            'LogType' => 'CarLog',
            'Time' => time(),
            'DrctnFlr' => '-02',
            'MCSS' => 'STB',
            'OpMode' => 'INA',
            'DoorStats' => '][**',
            'DoorCmd' => 'C6:C1>',
            'OCSS' => 'GTN02',
            'Load' => '002%',
        ], $merge);
    }
}

我只希望sensorId属性在该类中的所有测试中保持不变。

当测试之间存在依赖关系时，必须使用@取决于注释。这可以确保测试的执行顺序是正确的，也可以在测试之间传递值。不要让senorId持久化，只需将它从一个测试传递到另一个测试。
