引言
最近使用到laravel的consolo命令行工具,在編寫命令,想寫一些測試的時候,發(fā)現(xiàn)官方文檔中并沒有提到command的測試方法。花了點(diǎn)時間,翻墻找了資料,實(shí)踐成功并記錄一下,方便更多人。
測試方法
大家都知道Laravel中使用了很多Symfony的成熟組件,Laravel的console組件使用的就是Symfony/console。
幸運(yùn)的是,Symfony/console 組件中提供了用于command測試的CommandTester, 使用方法如下
... use FooCommand; use Symfony\Component\Console\Application; use Symfony\Component\Console\Tester\CommandTester; ... public function testSample(){ //創(chuàng)建一個console測試應(yīng)用平臺,用來搭載測試的命令 $application = new Application(); //創(chuàng)建待測試的command $testedCommand = $this->app->make(FooCommand::class); //設(shè)置命令執(zhí)行需要的laravel依賴 $testedCommand->setLaravel(app()); //添加待測試的command到測試應(yīng)用上 //同時command 也綁定 application $application->add($testedCommand); //實(shí)例化命令測試類 $commandTester = new CommandTester($testedCommand); //命令輸入流,對應(yīng)每次交互需要提供的輸入內(nèi)容 $commandTester->setInputs([ //... ]); //執(zhí)行命令 $commandTester->execute(['command' => $testedCommand->getName()]); //對命令執(zhí)行結(jié)果進(jìn)行斷言測試,主要是依靠正則判斷 //$commandTester->getDisplay() 方法可以獲取命令執(zhí)行后的輸出結(jié)果 $this->assertRegExp("/some reg/", $commandTester->getDisplay()); }
示例
我們現(xiàn)在有一個手動創(chuàng)建新用戶的命令createUser,作用就是手動創(chuàng)建一個用戶。
需要交互式讓用戶輸入name,email,password,comfirm password,這些數(shù)據(jù)。
待測試的command
line($this->description); // 獲取輸入的數(shù)據(jù) $data = [ 'name' => $this->ask('What\'s your name?'), 'email' => $this->ask('What\'s your email?'), 'password' => $this->secret('What\'s your password?'), 'password_confirmation' => $this->secret('Pleas confirm your password.') ]; // 驗(yàn)證輸入內(nèi)容 $validator = $this->makeValidator($data); if ($validator->fails()) { foreach ($validator->errors()->toArray() as $error) { foreach ($error as $message) { $this->error($message); } } return; } // 向用戶確認(rèn)輸入信息 if (!$this->confirm('Confirm your info: ' . PHP_EOL . 'name:' . $data['name'] . PHP_EOL . 'email:' . $data['email'] . PHP_EOL . 'is this correct?')) { return; } // 注冊 $user = $this->create($data); event(new Registered($user)); $this->line('User ' . $user->name . ' successfully registered'); } /** * Get a validator for an incoming registration request. * * @param array $data * @return \Illuminate\Contracts\Validation\Validator */ protected function makeValidator($data) { return Validator::make($data, [ 'name' => 'required|string|max:255|unique:users', 'email' => 'required|string|email|max:255|unique:users', 'password' => 'required|string|min:6|confirmed' ]); } /** * Create a new user instance after a valid registration. * * @param array $data * @return \App\User */ protected function create($data) { return User::create([ 'name' => $data['name'], 'email' => $data['email'], 'password' => bcrypt($data['password']) ]); } }
正確的結(jié)果
如果正確輸入信息的話,會得到如下輸出
$ path-to-your-app/app# php artisan createUser create new user for system manually What's your name?: > vestin What's your email?: > correct@abc.com What's your password?: > Pleas confirm your password.: > Confirm your info: name:vestin email:correct@abc.com is this correct? (yes/no) [no]: > yes User vestin successfully registered
想要測試的內(nèi)容
我想要測試兩塊內(nèi)容:
1.數(shù)據(jù)輸入驗(yàn)證測試
● email有效性測試
● password兩次輸入是否相同的測試
2.正確創(chuàng)建用戶測試
● 編寫單元測試
app->make(CreateUser::class); $testedCommand->setLaravel(app()); $application->add($testedCommand); $commandTester = new CommandTester($testedCommand); $commandTester->setInputs(['Vestin', 'badEmail@abc', '123456', '654321']); $commandTester->execute(['command' => $testedCommand->getName()]); // assert $this->assertRegExp("/The email must be a valid email address/", $commandTester->getDisplay()); $commandTester->setInputs(['vestin', 'correct@abc.com', '123456', '654321']); $commandTester->execute(['command' => $testedCommand->getName()]); // assert $this->assertRegExp("/The password confirmation does not match/", $commandTester->getDisplay()); } /** * 測試成功注冊用戶 * * @return void */ public function testSuccess() { $application = new Application(); $testedCommand = $this->app->make(CreateUser::class); $testedCommand->setLaravel(app()); $application->add($testedCommand); $commandTester = new CommandTester($testedCommand); $commandTester->setInputs(['Vestin', 'correct@abc.com', '123456', '123456', 'y']); $commandTester->execute(['command' => $testedCommand->getName()]); // assert $this->assertRegExp("/User Vestin successfully registered/", $commandTester->getDisplay()); $this->assertDatabaseHas('users', [ 'email' => 'correct@abc.com', 'name' => 'Vestin' ]); } }
執(zhí)行測試
$ path-to-your-app/app# ./vendor/bin/phpunit PHPUnit 6.4.3 by Sebastian Bergmann and contributors. .. 3 / 3 (100%) Time: 659 ms, Memory: 14.00MB
