My first test

Hi there,

This is my first test, so be easy on me.

Please give me your thoughts.

class SearchEmployeeByIdTest extends TestCase
{
    use DatabaseTransactions;

    /**
     * Search an employee by the given id
     * @test
     * @return void
     */
    public function it_finds_an_employee_by_id()
    {
        $employee_id = '00007F65E9';
        $employeeName = 'John';

        $company = factory(Company::class)->create();
        $plant = factory(Plant::class)->create();
        $company->plants()->save($plant);

        $employees = factory(Employee::class, 4)->create();
        $plant->employees()->saveMany([
            $employees[0], 
            $employees[1], 
            $employees[2], 
            $employees[3]
        ]);

        $employeeWithId = factory(Employee::class)->create([
            'name' => $employeeName, 
            'employee_id' => $employee_id
        ]);
        $plant->employees()->save($employeeWithId);

        $this->assertEquals($employee, $employeeWithId->employee_id);
        $this->assertCount(4, $employees);

        $this->actingAs($plant)
            ->withSession([
                'author_id' => $plant->id,
                'company_id' => $company->id
            ])
            ->visit('/employee/search?employee_id=' . $employee_id)
            ->see($employeeName);
    }
}

Thank you!
