Col*_*ynn 5 testing configuration phpunit cakephp cakephp-3.0
我曾经bin/cake bake plugin PluginName创建过一个插件.部分原因是它创建phpunit.xml.dist,但烘焙不会创建所需的文件夹结构或tests/bootstrap.php文件.
问题
我运行时收到"未执行测试"消息phpunit:
$ phpunit
PHPUnit 5.1.3 by Sebastian Bergmann and contributors.
Time: 239 ms, Memory: 4.50Mb
No tests executed!
背景资料
我在我的插件文件夹下创建了我的测试tests/TestCase.我不认为它们是问题,但我会在最后发布它们.
我正在使用默认phpunit.xml.dist文件,我正在使用它tests/bootstrap.php:
$findRoot = function ($root) {
do {
$lastRoot = $root;
$root = dirname($root);
if (is_dir($root . '/vendor/cakephp/cakephp')) {
return $root;
}
} while ($root !== $lastRoot);
throw new Exception("Cannot find the root of the application, unable to run tests");
};
$root = $findRoot(__FILE__);
unset($findRoot);
chdir($root);
define('ROOT', $root);
define('APP_DIR', 'App');
define('WEBROOT_DIR', 'webroot');
define('APP', ROOT . '/tests/App/');
define('CONFIG', ROOT . '/tests/config/');
define('WWW_ROOT', ROOT . DS . WEBROOT_DIR . DS);
define('TESTS', ROOT . DS . 'tests' . DS);
define('TMP', ROOT . DS . 'tmp' . DS);
define('LOGS', TMP . 'logs' . DS);
define('CACHE', TMP . 'cache' . DS);
define('CAKE_CORE_INCLUDE_PATH', ROOT . '/vendor/cakephp/cakephp');
define('CORE_PATH', CAKE_CORE_INCLUDE_PATH . DS);
define('CAKE', CORE_PATH . 'src' . DS);
require ROOT . '/vendor/autoload.php';
require CORE_PATH . 'config/bootstrap.php';
单元测试
住在这里 tests/TestCase/Color.php
<?php
namespace Contrast\TestCase;
use Cake\TestSuite\TestCase;
use Contrast\Text\Color;
/**
* Contrast Text Color tests
*/
class TextColorTest extends TestCase
{
/**
* @test
* @return void
*/
public function testShouldHandleVarietyOfColors()
{
# Returns black
$this->assertEquals(Color::getBlackWhiteContrast('#FFFFFF'), 'black');
// Why won't you fail??
$this->assertEquals(true, false);
}
应该是基本名称空间Contrast\Test,这也是应该将bake添加到应用程序composer.json文件autoload和autoload-dev部分以及烘焙插件composer.json文件中的内容.如果您拒绝烘焙以编辑yout composer.json文件,则应手动添加自动加载条目
"autoload": {
"psr-4": {
// ...
"Contrast\\": "./plugins/Contrast/src"
}
},
"autoload-dev": {
"psr-4": {
// ...
"Contrast\\Test\\": "./plugins/Contrast/tests"
}
},
并重新转储自动加载器
$ composer dump-autoload
所以你的示例测试的命名空间应该是Contrast\Test\TestCase.
此外,测试文件需要加上后缀,Test以便PHPUnit识别它们.并且为了使文件可以自动加载,你应该坚持使用PSR-4,即文件应该与类同名,即你的测试文件应该被命名TextColorTest.php,而不是Color.php.
在将插件作为应用程序的一部分进行测试时,插件测试中不一定需要一个bootstrap文件(虽然bake应该生成一个),因为你可以使用你的应用程序的配置来运行它们,tests/bootstrap.php包含应用程序引导程序文件(config/bootstrap.php)的测试引导程序文件().
因此,测试将从您的应用程序基础文件夹运行,您必须通过插件路径,如
$ vendor/bin/phpunit plugins/Contrast
或者你在你的应用程序主phpunit配置文件中添加一个额外的插件测试套件,它说 <!-- Add your plugin suites -->
<testsuite name="Contrast Test Suite">
<directory>./plugins/Contrast/tests/TestCase</directory>
</testsuite>
这样,插件测试将与您的应用程序测试一起运行.
最后,您还可以从插件目录运行测试,因为存在正确的引导程序文件.目前的默认值如下:
<?php
/**
* Test suite bootstrap for Contrast.
*
* This function is used to find the location of CakePHP whether CakePHP
* has been installed as a dependency of the plugin, or the plugin is itself
* installed as a dependency of an application.
*/
$findRoot = function ($root) {
do {
$lastRoot = $root;
$root = dirname($root);
if (is_dir($root . '/vendor/cakephp/cakephp')) {
return $root;
}
} while ($root !== $lastRoot);
throw new Exception("Cannot find the root of the application, unable to run tests");
};
$root = $findRoot(__FILE__);
unset($findRoot);
chdir($root);
require $root . '/config/bootstrap.php';
也可以看看
在以独立方式开发插件时,这就是您真正需要一个设置环境的引导文件,而这正是composer.json使用bake生成的插件文件的地方.默认情况下,后者看起来像
{
"name": "your-name-here/Contrast",
"description": "Contrast plugin for CakePHP",
"type": "cakephp-plugin",
"require": {
"php": ">=5.4.16",
"cakephp/cakephp": "~3.0"
},
"require-dev": {
"phpunit/phpunit": "*"
},
"autoload": {
"psr-4": {
"Contrast\\": "src"
}
},
"autoload-dev": {
"psr-4": {
"Contrast\\Test\\": "tests",
"Cake\\Test\\": "./vendor/cakephp/cakephp/tests"
}
}
}
烘焙插件时生成的测试引导程序文件无法开箱即用,因为它只会尝试加载config/bootstrap.php插件文件,默认情况下甚至不存在.
测试引导程序文件需要做什么取决于插件当然在做什么,但至少应该如此
例如,这是一个tests/bootstrap.php示例,其中包含当前cakephp/app应用程序模板的功能副本,即它基本上配置了一个完整的应用程序环境(定义了应用程序在tests/TestApp文件夹中):
// from `config/paths.php`
if (!defined('DS')) {
define('DS', DIRECTORY_SEPARATOR);
}
define('ROOT', dirname(__DIR__));
define('APP_DIR', 'test_app');
define('APP', ROOT . DS . 'tests' . DS . APP_DIR . DS);
define('CONFIG', ROOT . DS . 'config' . DS);
define('WWW_ROOT', APP . 'webroot' . DS);
define('TESTS', ROOT . DS . 'tests' . DS);
define('TMP', ROOT . DS . 'tmp' . DS);
define('LOGS', TMP . 'logs' . DS);
define('CACHE', TMP . 'cache' . DS);
define('CAKE_CORE_INCLUDE_PATH', ROOT . DS . 'vendor' . DS . 'cakephp' . DS . 'cakephp');
define('CORE_PATH', CAKE_CORE_INCLUDE_PATH . DS);
define('CAKE', CORE_PATH . 'src' . DS);
// from `config/app.default.php` and `config/bootstrap.php`

为了从测试应用程序文件夹中自动加载类,您必须在composer.json文件中添加相应的自动加载条目(并再次重新转储自动加载器),如:
"autoload-dev": {
"psr-4": {
"Contrast\\Test\\": "tests",
"Contrast\\TestApp\\": "tests/test_app/src", // < here we go
"Cake\\Test\\": "./vendor/cakephp/cakephp/tests"
}
}
所以现在使用bake创建插件,配置环境并安装CakePHP和PHPUnit依赖项,您应该能够像使用应用程序一样运行测试,即
$ vendor/bin/phpunit
