Common skills of unit test (PHPUnit + Laravel)

• Example code:

<?php namespace Tests\Unit; use App\Services\ClientService; use Tests\TestCase; class ClientServiceTest extends TestCase { /** * @dataProvider addProviderAppUpdateData * * @param $appId * @param $result */ public function testAppUpdateData($appId, $result) { $data = (new ClientService($appId))->appUpdateData(); $this->assertTrue(count(array_intersect_assoc($data, $result)) == count($result)); } public function addProviderAppUpdateData() { return [ 'null' => [null, ['status' => 0, 'isIOS' => false, 'latest_version' => 'V']], 'error app id' => ['sdas123123', ['status' => 0, 'isIOS' => false, 'latest_version' => 'V']], 'android force update' => ['bx7_3.3.5_120', ['status' => 0, 'isIOS' => false]], 'ios force update' => ['apple_3.3.2_117', ['status' => 1, 'isIOS' => true]], 'android soft update' => ['sanxing_3.3.2_117', ['status' => 2, 'isIOS' => false]], 'ios soft update' => ['apple_3.3.3_118', ['status' => 2, 'isIOS' => true]], 'android normal' => ['fhqd_3.3.6_121', ['status' => 1, 'isIOS' => false]], 'ios normal' => ['apple_3.3.5_120', ['status' => 1, 'isIOS' => true]], 'h5' => ['h5_3.3.3', ['status' => 1, 'isIOS' => false]] ]; } }

• Assertion success result:

Commonly used are assertTrue(), assertFalse(), assertNull(), assertEquals(), assertThat().

assertThat() custom assertion. Common constraints include isNull(), isTrue(), isFalse(), isInstanceOf(); common combined constraints logicalOr(), logicalAnd(). For example, check whether the returned result is null or ApiApp class.

• Example code:

<?php namespace Tests\Unit; use App\Models\ApiApp; use App\Services\SystemConfigService; use Tests\TestCase; class SystemConfigServiceTest extends TestCase { /** * @dataProvider additionProviderGetLatestUpdateAppApi * * @param $appType */ public function testGetLatestUpdateAppApi($appType) { $result = SystemConfigService::getLatestUpdateAppApi($appType); $this->assertThat($result, $this->logicalOr($this->isNull(), $this->isInstanceOf(ApiApp::class))); } public function additionProviderGetLatestUpdateAppApi() { return [ 'apple' => [1], 'android' => [2], 'null' => [9999] ]; } }

• Assertion success result:

Use expectExceptionCode() to detect the error code. It is not recommended to detect the error information copy. For example, check whether 3026 error code is thrown after the device is locked.

• Example code:

<?php namespace Tests\Unit; use App\Services\UserSecurityService; use Illuminate\Support\Facades\Cache; use Tests\TestCase; class UserSecurityServiceTest extends TestCase { public static $userId = 4; /** * Equipment lock detection * @throws \App\Exceptions\UserException */ public function testDeviceCheckLock() { $this->expectExceptionCode(3026); Cache::put('device-login-error-account-', '1,2,3,4,5', 300); UserSecurityService::$request = null; UserSecurityService::$udid = null; UserSecurityService::deviceCheck(self::$userId); } }

• Assertion success result:

• If only private methods can be tested, the ReflectionMethod() reflection method can be used, setAccessible(true) setting method can be used, and invokeArgs() or invoke() can be used to call methods (invokeArgs passes parameters as arrays). For example, check whether IP is in the white list.
• Example code:

Detected code:

namespace App\Facades\Services; /** * Class WebDefender */ class WebDefenderService extends BaseService { //ip white list private $ipWhiteList = [ '10.*', '172.18.*', '127.0.0.1' ]; /** * ip Is it in the white list * * @param string $ip * * @return bool */ private function checkIPWhiteList($ip) { if (!$this->ipWhiteList || !is_array($this->ipWhiteList)) { return false; } foreach ($this->ipWhiteList as $item) { if (preg_match("/{$item}/", $ip)) { return true; } } return false; } }

Test method:

<?php namespace Tests\Unit; use App\Facades\Services\WebDefenderService; use Tests\TestCase; class WebDefenderTest extends TestCase { /** * Test IP white list * @dataProvider additionProviderIp * * @param $ip * @param $result * * @throws \ReflectionException */ public function testIPWhite($ip, $result) { $checkIPWhiteList = new \ReflectionMethod(WebDefenderService::class, 'checkIPWhiteList'); $checkIPWhiteList->setAccessible(true); $this->assertEquals($result, $checkIPWhiteList->invokeArgs(new WebDefenderService(), [$ip])); } public function additionProviderIp() { return [ '10 ip' => ['10.1.1.7', true], '172 ip' => ['172.18.2.5', true], '127 ip' => ['127.0.0.1', true], '192 ip' => ['192.168.0.1', false] ]; } }

• To test the private property, use ReflectionClass(), getProperty(), setValue(), getMethod(), and setAccessible(true) to set the property and method. For example, detect white list path.
• Example code:

Detected code:

<?php namespace App\Facades\Services; use App\Exceptions\ExceptionCode; use App\Exceptions\UserException; use Illuminate\Support\Facades\Cache; /** * CC Attack defender * Class WebDefender */ class WebDefenderService extends BaseService { //Path white list (regular) private $pathWhiteList = [ //'^auth\/(.*)', ]; private static $request = null; /** * Whether the request path is in the white list * * @return bool */ private function checkPathWhiteList() { $path = ltrim(self::$request->getPathInfo(), '/'); if (!$path || !$this->pathWhiteList || !is_array($this->pathWhiteList)) { return false; } foreach ($this->pathWhiteList as $item) { if (preg_match("/$item/", $path)) { return true; } } return false; } }

Test method:

<?php namespace Tests\Unit; use App\Facades\Services\WebDefenderService; use Illuminate\Http\Request; use Tests\TestCase; class WebDefenderTest extends TestCase { /** * Detect whitelist path * @dataProvider additionProviderPathWhiteList * * @param $pathProperty * @param $request * @param $result * * @throws \ReflectionException */ public function testCheckPathWhiteList($pathProperty, $request, $result) { $reflectedClass = new \ReflectionClass('App\Facades\Services\WebDefenderService'); $webDefenderService = new WebDefenderService(); $reflectedPathWhiteList = $reflectedClass->getProperty('pathWhiteList'); $reflectedPathWhiteList->setAccessible(true); $reflectedPathWhiteList->setValue($webDefenderService, $pathProperty); $reflectedRequest = $reflectedClass->getProperty('request'); $reflectedRequest->setAccessible(true); $reflectedRequest->setValue($request); $reflectedMethod = $reflectedClass->getMethod('checkPathWhiteList'); $reflectedMethod->setAccessible(true); $this->assertEquals($result, $reflectedMethod->invoke($webDefenderService)); } public function additionProviderPathWhiteList() { $allPath = ['.*']; $checkPath = ['^auth\/(.*)']; $authSendSmsRequest = new Request([], [], [], [], [], ['HTTP_HOST' => 'api.dev.com', 'REQUEST_URI' => '/auth/sendSms']); $indexRequest = new Request([], [], [], [], [], ['HTTP_HOST' => 'api.dev.com', 'REQUEST_URI' => '/']); $noMatchRequest = new Request([], [], [], [], [], ['HTTP_HOST' => 'api.dev.com', 'REQUEST_URI' => '/product/sendSms']); return [ 'index' => [[], $authSendSmsRequest, false], 'no request' => [$allPath, $indexRequest, false], 'all request' => [$allPath, $authSendSmsRequest, true], 'check auth sms' => [$checkPath, $authSendSmsRequest, true], 'check path no match' => [$checkPath, $noMatchRequest, false] ]; } }

Reports exported using -- coverage HTML include class and attribute coverage, row coverage, function and method coverage. You can view the coverage of the current unit test. For example, output the code coverage of webdefender test to the desktop (phpunit tests / unit / webdefender test -- coverage HTML ~ / desktop / test)

In the configuration file (phpunit.xml), set processuncoveredfiles from whitelist = true, set the directory with < Directory > label, and set the file with < File > label. For example, specify all files in the app/Services directory and app / facades / services / webdefender service.php in the report.
