Question

环境

Laravel版本： 5.1.45（LTS）
PHP版本： 5.6.1

描述

我正在尝试使用Laravel Task Scheduling每1分钟运行一次命令。

尝试

我已将此行添加到我的cron标签文件

* * * * * php artisan schedule:run >> /dev/null 2>&1

这是我的 /app/Console/Kernel.php

<?php

namespace App\Console;

use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;

class Kernel extends ConsoleKernel
{
    /**
     * The Artisan commands provided by your application.
     *
     * @var array
     */
    protected $commands = [
        \App\Console\Commands\Inspire::class,
    ];

    /**
     * Define the application's command schedule.
     *
     * @param  \Illuminate\Console\Scheduling\Schedule  $schedule
     * @return void
     */
    protected function schedule(Schedule $schedule)
    {
        $schedule->command('inspire')->hourly();
        $schedule->command('echo "Happy New Year!" ')->everyMinute(); //<---- ADD HERE        }
}

我添加了这一行$schedule->command('echo "Happy New Year!" ')->everyMinute();

问题

如何测试？

如何触发显示的回声？

我怎么知道我做的是不是错了？

我现在正在接受任何建议。

任何提示/建议/帮助都将非常感谢！

Answer 1

command() runs an artisan command. What you're trying to achieve - issuing a command to the OS - is done by exec('echo "Happy New Year!"')

Testing depends on what you want to test:

Whether the scheduler (every minute) is working?

In this case, you don't have to. It is tested in the original framework code.

Whether the command succeeds?

Well, you can manually run php artisan schedule:run and see the output.

The scheduler does not produce any output on default (>> /dev/null 2>&1). You can, however, redirect the output of the runned scripts to any file by chaining writeOutputTo() or appendOutputTo() (https://laravel.com/docs/5.1/scheduling#task-output).

For more complex logic, write a console command instead (https://laravel.com/docs/5.1/artisan#writing-commands) and use command() - this way you can write nice, testable code.

如果要对事件的计划进行单元测试，可以使用此示例。它基于默认的inspire命令：

public function testIsAvailableInTheScheduler()
{
    /** @var \Illuminate\Console\Scheduling\Schedule $schedule */
    $schedule = app()->make(\Illuminate\Console\Scheduling\Schedule::class);

    $events = collect($schedule->events())->filter(function (\Illuminate\Console\Scheduling\Event $event) {
        return stripos($event->command, 'YourCommandHere');
    });

    if ($events->count() == 0) {
        $this->fail('No events found');
    }

    $events->each(function (\Illuminate\Console\Scheduling\Event $event) {
        // This example is for hourly commands.
        $this->assertEquals('0 * * * * *', $event->expression);
    });
}

Answer 3

根据Michiel的回答，我使用Illuminate\Console\Scheduling\Event中包含的方法来测试事件是否应该在给定日期运行。

我使用Carbon::setTestNow()模拟了当前日期，因此when()和skip()过滤器中的任何基于日期的逻辑都会按预期运行。

use Tests\TestCase;
use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Console\Scheduling\Event;

use Cron\CronExpression;
use Carbon\Carbon;


class ScheduleTest extends TestCase {


    public function testCompanyFeedbackSchedule()
    {
        $event = $this->getCommandEvent('your-command-signature');

        $test_date = Carbon::now()->startOfDay()->addHours(8);

        for ($i=0; $i < 356; $i++) { 
            $test_date->addDay();
            Carbon::setTestNow($test_date);

            // Run the when() & skip() filters
            $filters_pass = $event->filtersPass($this->app);
            // Test that the Cron expression passes
            $date_passes = $this->isEventDue($event);
            $will_run = $filters_pass && $date_passes;

            // Should only run on first friday of month
            if ($test_date->format('l') === 'Friday' && $test_date->weekOfMonth === 1) {
                $this->assertTrue($will_run, 'Task should run on '. $test_date->toDateTimeString());
            } else {
                $this->assertFalse($will_run, 'Task should not run on '. $test_date->toDateTimeString());
            }
        }
    }


    /**
     * Get the event matching the given command signature from the scheduler
     * 
     * @param  string  $command_signature
     * 
     * @return Illuminate\Console\Scheduling\Event
     */
    private function getCommandEvent($command_signature)
    {
        $schedule = app()->make(Schedule::class);

        $event = collect($schedule->events())->first(function (Event $event) use ($command_signature) {
            return stripos($event->command, $command_signature);
        });

        if (!$event) {
            $this->fail('Event for '. $command_signature .' not found');
        }

        return $event;
    }


    /**
     * Determine if the Cron expression passes.
     * 
     * Copied from the protected method Illuminate\Console\Scheduling\Event@isEventDue
     * 
     * @return bool
     */
    private function isEventDue(Event $event)
    {
        $date = Carbon::now();

        if ($event->timezone) {
            $date->setTimezone($event->timezone);
        }

        return CronExpression::factory($event->expression)->isDue($date->toDateTimeString());
    }
}

Answer 4

同样以 Michiel's anwer 为基础，至少在 L8 中是有区别的。

代替$event->command：

$events = collect($schedule->events())->filter(function (Event $event) {
  return stripos($event->command, 'YourCommandHere');
});

需要 $event->description：

$events = collect($schedule->events())->filter(function (Event $event) {
  return stripos($event->description, 'YourCommandHere');
});

我在研究 Tinker 时发现了这个：

>>> app()->make(\Illuminate\Console\Scheduling\Schedule::class)->events();
=> [
     Illuminate\Console\Scheduling\CallbackEvent {#3496
       +command: null,
       +expression: "* * * * *",
       +timezone: "UTC",
       +user: null,
       +environments: [],
       +evenInMaintenanceMode: false,
       +withoutOverlapping: false,
       +onOneServer: false,
       +expiresAt: 1440,
       +runInBackground: false,
       +output: "/dev/null",
       +shouldAppendOutput: false,
       +description: "App\Jobs\GenerateSuggestion",
       +mutex: Illuminate\Console\Scheduling\CacheEventMutex {#3498
         +cache: Illuminate\Cache\CacheManager {#282},
         +store: null,
       },
       +exitCode: null,
     },
   ]
