1. 数据供给器
用来提供参数和结果，使用 @dataprovider 标注来指定使用哪个数据供给器方法。例如检测app升级数据是否符合预期，addproviderappupdatedata()提供测试的参数和结果。testappupdatedata()检测appupdatedata()返回的结果是否和给定的预期结果相等，即如果$appid='apple_3.3.2_117', $result=['status' => 0, 'isios' => false], 则$data中如果含有['status' => 0, 'isios' => false], 则断言成功。建议在数据提供器，逐个用字符串键名对其命名，这样在断言失败的时候将输出失败的名称，更容易定位问题。
示例代码：
<?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]]
];
}
}
断言成功结果：
2. 断言方法
常用有asserttrue(), assertfalse(), assertnull(), assertequals(), assertthat()。
assertthat()自定义断言。常用的约束有isnull()、istrue()、isfalse()、isinstanceof()；常用的组合约束logicalor()、logicaland()。例如检测返回的结果是否是null或apiapp类。
示例代码：
<?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]
];
}
}
断言成功结果：
3. 对异常进行测试
使用expectexceptioncode()对错误码进行检测，不建议对错误信息文案进行检测。例如检测设备被锁后是否抛出3026错误码。
示例代码：
<?php
namespace tests\unit;
use app\services\usersecurityservice;
use illuminate\support\facades\cache;
use tests\testcase;
class usersecurityservicetest extends testcase
{
public static $userid = 4;
/**
* 设备锁检测
* @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);
}
}
断言成功结果：
4. 测试私有属性和私有方法使用反射机制
如果只测试私有方法可使用reflectionmethod()反射方法，使用setaccessible(true)设置方法可访问，并使用invokeargs()或invoke()调用方法(invokeargs将参数作为数组传递)。例如检测ip是否在白名单中。
示例代码：
被检测代码：
namespace app\facades\services;
/**
* class webdefender
*/
class webdefenderservice extends baseservice
{
//ip白名单
private $ipwhitelist = [
'10.*',
'172.18.*',
'127.0.0.1'
];
/**
* ip是否在白名单中
*
* @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;
}
}
检测方法：
<?php
namespace tests\unit;
use app\facades\services\webdefenderservice;
use tests\testcase;
class webdefendertest extends testcase
{
/**
* 测试ip白名单
* @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]
];
}
}
测试私有属性可使用reflectionclass(), 获取属性用getproperty(), 设置属性的值用setvalue(), 获取方法用getmethod(), 设置属性和方法可被访问使用setaccessible(true)。例如检测白名单路径。
示例代码：
被检测代码：
<?php
namespace app\facades\services;
use app\exceptions\exceptioncode;
use app\exceptions\userexception;
use illuminate\support\facades\cache;
/**
* cc攻击防御器
* class webdefender
*/
class webdefenderservice extends baseservice
{
//路径白名单(正则)
private $pathwhitelist = [
//'^auth\/(.*)',
];
private static $request = null;
/**
* 请求路径是否在白名单中
*
* @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;
}
}
检测方法：
<?php
namespace tests\unit;
use app\facades\services\webdefenderservice;
use illuminate\http\request;
use tests\testcase;
class webdefendertest extends testcase
{
/**
* 检测白名单路径
* @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. 代码覆盖率
使用--coverage-html导出的报告含有类与特质覆盖率、行覆盖率、函数与方法覆盖率。可查看当前单元测试覆盖的范围。例如输出webdefendertest的代码覆盖率到桌面(phpunit tests/unit/webdefendertest --coverage-html ~/desktop/test)
6. 指定代码覆盖率报告要包含哪些文件
在配置文件(phpunit.xml)里设置whitelist中的processuncoveredfilesfromwhitelist=true, 设置目录用<directory>标签，设置文件用<file>标签。例如指定app/services目录下的所有文件和app/facades/services/webdefenderservice.php在报告中。
示例代码：
<?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>
</testsuite>
</testsuites>
<filter>
<whitelist processuncoveredfilesfromwhitelist="true">
<directory suffix=".php">./app/services</directory>
<file>./app/facades/services/webdefenderservice.php</file>
</whitelist>
</filter>
<php>

<server name="cache_driver" value="credis"/>
<server name="mail_driver" value="array"/>

<server name="session_driver" value="array"/>
<server name="app_config_cache" value="bootstrap/cache/config.phpunit.php"/>
<server name="app_services_cache" value="bootstrap/cache/services.phpunit.php"/>
<server name="app_packages_cache" value="bootstrap/cache/packages.phpunit.php"/>
<server name="app_routes_cache" value="bootstrap/cache/routes.phpunit.php"/>
<server name="app_events_cache" value="bootstrap/cache/events.phpunit.php"/>
</php>
</phpunit>
