While testing model deletion, use assertModelMissing instead assertDatabaseMissing.
/** @test */public function allowed_user_can_delete_task(){ $task = Task::factory()->for($this->project)->create(); $this->deleteJson($task->path()) ->assertNoContent(); // Instead of assertDatabaseMissing to check if the model missing from the database $this->assertDatabaseMissing('tasks', ['id' => $task->id]); // use directly assertModelMissing $this->assertModelMissing($task);}
