除了简化 HTTP 测试外,Laravel 还为测试需要用户输入的控制台应用提供了简单的 API。
Laravel 允许我们使用 expectsQuestion
方法为控制台命令轻松“模拟”用户输入,此外,我们还可以使用 assertExitCode
和 expectsOutput
方法指定控制台命令退出码和期望输出的文本。例如,考虑下面这个控制台命令(定义在 routes/console.php 中):
Artisan::command('question', function () {
$name = $this->ask('What is your name?');
$language = $this->choice('Which language do you program in?', [
'PHP',
'Golang',
'Python',
]);
$this->line('Your name is '.$name.' and you program in '.$language.'.');
});
我们可以为 question 命令编写测试代码如下,其中使用到了 expectsQuestion
、expectsOutput
和 assertExitCode
方法:
/**
* Test a console command.
*
* @return void
*/
public function testConsoleCommand()
{
$this->artisan('question')
->expectsQuestion('What is your name?', 'Taylor Otwell')
->expectsQuestion('Which language do you program in?', 'PHP')
->expectsOutput('Your name is Taylor Otwell and you program in PHP.')
->assertExitCode(0);
}
当编写的命令期望获得 “yes” 或 “no” 形式的确认时,可以使用 expectsConfirmation
方法:
$this->artisan('module:import')
->expectsConfirmation('Do you really wish to run this command?', 'no')
->assertExitCode(1);
