如何对与日期相关的Symfony命令进行测试？

Question

我运行一个处理上个月事务的CLI Symfony命令。它是CLI -我不能只是模拟系统时钟，所以我如何用Behat测试它？现在是11月份，下面的场景将在12月份失败：

  Scenario: Do something with last month transactions
    Given there is a transaction "7ccf7387" for 2020-10
    And there is a transaction "39d7f278" for 2020-10
    When I execute "bin/console billing:last-month" from project root
    Then command should succeed
    And output should contain "Closed 2 transactions"

这是当前的命令实现：

    final class CloseLastMonth extends Command
    {
        /* ... */
    
        protected function execute(InputInterface $input, OutputInterface $output): int
        {
            $month = (GregorianCalendar::UTC())->currentMonth()->previous();
            $trxs = $this->bus->dispatch(new GetActiveTrxsByMonthQuery($month));
            foreach ($trxs as $trx) {
                $this->bus->dispatch(new CloseTransactionCommand($trx->id));
            }
            $this->io->success(sprintf('Closed %d transactions', count($trxs)));
    
            return 0;
        }
    
        /* ... */
    }

我可以强制用户总是在命令参数中传递当前月份，但这并不优雅。新的Symfony服务总是返回当前月份，这是一种夸张的做法。

更好的write your own step definition

/**
 * @Given /^There is a transaction "([^"]*)" for last month$/
 */
public function thereIsATransaction(string $transactionId) {}

这样，您可以简单地执行以下操作：

Given there is a transaction "7ccf7387" for last month
    And there is a transaction "39d7f278" for last month
