Laravel测试类属性不持久

Question

我正在尝试设置一个sensorId属性，该属性将由我的特性测试中的每个方法使用。问题是它在两次测试之间没有持续存在。

这是我的测试课程：

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属性在这个类中的所有测试中都保持不变。

当测试之间存在依赖关系时，必须使用@depends注释。这样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。与其使sensorId持久化，不如将其从一个测试传递到另一个测试。
