尝试使用ask()函数为laravel php artisan命令编写测试。我之前从未使用过嘲弄,但是当我尝试运行测试时,它会冻结,所以我想,我做错了。
MyCommand.php:
public function handle()
{
$input['answer1'] = $this->ask('Ask question 1');
$input['answer2'] = $this->ask('Ask question 2');
$input['answer3'] = $this->ask('Ask question 3');
//--- processing validation
$validator = Validator::make($input, [
'answer1' => 'required',
'answer2' => 'required',
'answer3' => 'required',
]);
if ($validator->fails()) {
// processing error
}
} else {
// saving to DB
}
}
我的单元测试:
$command = m::mock('\App\Console\Commands\Questions');
$command->shouldReceive('ask')
->andReturn('Answer 1')
->shouldReceive('ask')
->andReturn('Answer 2')
->shouldReceive('ask')
->andReturn('Answer 3')
$this->artisan('myCommand:toRun');
$this->assertDatabaseHas('myTable', [
'question1' => 'answer1'
]);
//
答案 0 :(得分:0)
Laravel 5.4-5.6
这里的实际问题是,运行console命令正在等待用户输入,但是我们正在通过PHPUnit运行它,因此我们无法输入任何内容。
在单元测试中碰到限制可能会令人沮丧,但是您发现的限制最终可能是变相的祝福。
当前,您的实现与视图紧密结合(控制台命令,因此是管理员视图,但仍然是视图)。此处可以做的是将任何逻辑放在单独的类中, MyCommand
可以利用,PHPUnit可以实际对其进行测试。我们知道,如Laravel单元测试中所示,运行自定义命令的基本原理起作用,因此我们可以在一个单独的可测试类中卸载逻辑。
您的新班级可能看起来像这样:
class CommandLogic
{
public function getQuestion1Text()
{
return 'Ask question 1';
}
public function getQuestion2Text()
{
return 'Ask question 2';
}
public function getQuestion3Text()
{
return 'Ask question 3';
}
public function submit(array $input)
{
$validator = \Illuminate\Support\Facades\Validator::make($input, [
'answer1' => 'required',
'answer2' => 'required',
'answer3' => 'required',
]);
if ($validator->fails()) {
// processing error
} else {
// saving to DB
}
}
}
...您的实际单元测试,如下所示:
$commandLogic = new CommandLogic();
$sampleInput = [
'answer1' => 'test1',
'answer2' => 'test2',
'answer3' => 'test3',
];
$commandLogic->submit($sampleInput);
$this->assertDatabaseHas('myTable', [
'question1' => 'test1'
]);
...以及您的控制台命令,如下所示:
public function handle()
{
$commandLogic = new CommandLogic();
$input['answer1'] = $this->ask($commandLogic->getQuestion1Text());
$input['answer2'] = $this->ask($commandLogic->getQuestion2Text());
$input['answer3'] = $this->ask($commandLogic->getQuestion3Text());
$commandLogic->submit($input);
}
这将强制执行single responsibility principle并将代码库中的移动部分分开。我知道这听起来有点像个警察,但是在Laravel 5.4中测试这些东西很困难。如果您愿意升级到5.7或更高版本,请阅读以下内容...
Laravel 5.7 +
Laravel 5.7引入了能够运行控制台测试的功能,它满足了这个问题的确切要求-https://laravel.com/docs/5.7/console-tests。这更多的是完全集成测试,而不是单元测试。
