1. 數據供給器
用來提供參數和結果，使用 @dataProvider 標注來指定使用哪個數據供給器方法。例如檢測app升級數據是否符合預期，addProviderAppUpdateData()提供測試的參數和結果。testAppUpdateData()檢測appUpdateData()返回的結果是否和給定的預期結果相等，即如果$appId='apple_3.3.2_117', $result=['status' => 0, 'isIOS' => false], 則$data中如果含有['status' => 0, 'isIOS' => false], 則斷言成功。建議在數據提供器，逐個用字符串鍵名對其命名，這樣在斷言失敗的時候將輸出失敗的名稱，更容易定位問題。
示例代碼：
?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]]
];
}
}
斷言成功結果：
2. 斷言方法
常用有assertTrue(), assertFalse(), assertNull(), assertEquals(), assertThat()。
assertThat()自定義斷言。常用的約束有isNull()、isTrue()、isFalse()、isInstanceOf()；常用的組合約束logicalOr()、logicalAnd()。例如檢測返回的結果是否是null或ApiApp類。
示例代碼：
?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]
];
}
}
斷言成功結果：
3. 對異常進行測試
使用expectExceptionCode()對錯誤碼進行檢測，不建議對錯誤信息文案進行檢測。例如檢測設備被鎖后是否拋出3026錯誤碼。
示例代碼：
?php
namespace Tests\Unit;
use App\Services\UserSecurityService;
use Illuminate\Support\Facades\Cache;
use Tests\TestCase;
class UserSecurityServiceTest extends TestCase
{
public static $userId = 4;
/**
* 設備鎖檢測
* @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);
}
}
斷言成功結果：
4. 測試私有屬性和私有方法使用反射機制
如果只測試私有方法可使用ReflectionMethod()反射方法，使用setAccessible(true)設置方法可訪問，并使用invokeArgs()或invoke()調用方法(invokeArgs將參數作為數組傳遞)。例如檢測IP是否在白名單中。
示例代碼：
被檢測代碼：
namespace App\Facades\Services;
/**
* Class WebDefender
*/
class WebDefenderService extends BaseService
{
//ip白名單
private $ipWhiteList = [
'10.*',
'172.18.*',
'127.0.0.1'
];
/**
* ip是否在白名單中
*
* @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;
}
}
檢測方法：
?php
namespace Tests\Unit;
use App\Facades\Services\WebDefenderService;
use Tests\TestCase;
class WebDefenderTest extends TestCase
{
/**
* 測試IP白名單
* @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]
];
}
}
測試私有屬性可使用ReflectionClass(), 獲取屬性用getProperty(), 設置屬性的值用setValue(), 獲取方法用getMethod(), 設置屬性和方法可被訪問使用setAccessible(true)。例如檢測白名單路徑。
示例代碼：
被檢測代碼：
?php
namespace App\Facades\Services;
use App\Exceptions\ExceptionCode;
use App\Exceptions\UserException;
use Illuminate\Support\Facades\Cache;
/**
* CC攻擊防御器
* Class WebDefender
*/
class WebDefenderService extends BaseService
{
//路徑白名單(正則)
private $pathWhiteList = [
//'^auth\/(.*)',
];
private static $request = null;
/**
* 請求路徑是否在白名單中
*
* @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;
}
}
檢測方法：
?php
namespace Tests\Unit;
use App\Facades\Services\WebDefenderService;
use Illuminate\Http\Request;
use Tests\TestCase;
class WebDefenderTest extends TestCase
{
/**
* 檢測白名單路徑
* @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]
];
}
}
5. 代碼覆蓋率
使用--coverage-html導出的報告含有類與特質覆蓋率、行覆蓋率、函數與方法覆蓋率。可查看當前單元測試覆蓋的范圍。例如輸出WebDefenderTest的代碼覆蓋率到桌面(phpunit tests/unit/WebDefenderTest --coverage-html ~/Desktop/test)
6. 指定代碼覆蓋率報告要包含哪些文件
在配置文件(phpunit.xml)里設置whitelist中的processUncoveredFilesFromWhitelist=true, 設置目錄用directory>標簽，設置文件用file>標簽。例如指定app/Services目錄下的所有文件和app/Facades/Services/WebDefenderService.php在報告中。
示例代碼：
?xml version="1.0" encoding="UTF-8"?>
phpunit backupGlobals="false"
backupStaticAttributes="false"
bootstrap="tests/bootstrap.php"
colors="true"
convertErrorsToExceptions="true"
convertNoticesToExceptions="true"
convertWarningsToExceptions="true"
processIsolation="false"
stopOnFailure="false">
testsuites>
testsuite name="Unit">
directory suffix="Test.php">./tests/Unit/directory>
/testsuite>
testsuite name="Feature">
directory suffix="Test.php">./tests/Feature/directory>
