初始化注册异常运行时

Testing Is Documentation

tests/Kernel/Bootstrap/RegisterExceptionRuntimeTest.php

QueryPHP 在内核执行过程中会执行初始化，分为 4 个步骤，载入配置、载入语言包、注册异常运行时和遍历服务提供者注册服务。

内核初始化，包括 \Leevel\Kernel\IKernel::bootstrap 和 \Leevel\Kernel\IKernelConsole::bootstrap 均会执行上述 4 个步骤。

set_error_handler 设置错误处理函数

public function testSetErrorHandle(): void
{
    $this->expectException(\ErrorException::class);
    $this->expectExceptionMessage(
        'foo.'
    );

    $bootstrap = new RegisterExceptionRuntime();

    $container = Container::singletons();
    $app = new App4($container, $appPath = __DIR__.'/app');

    $this->assertInstanceof(IContainer::class, $container);
    $this->assertInstanceof(Container::class, $container);
    $this->assertInstanceof(IApp::class, $app);
    $this->assertInstanceof(Apps::class, $app);

    $this->invokeTestMethod($bootstrap, 'setErrorHandle', [400, 'foo.']);
}

set_exception_handler 设置异常处理函数

public function testSetExceptionHandler(): void
{
    $this->backupSystemEnvironment();
    $bootstrap = new RegisterExceptionRuntime1();

    $container = Container::singletons();
    $app = new App4($container, $appPath = __DIR__.'/app');

    $request = $this->createMock(Request::class);

    $request->method('isConsole')->willReturn(true);
    self::assertTrue($request->isConsole());

    $container->singleton('request', static function () use ($request) {
        return $request;
    });

    $runtime = $this->createMock(IRuntime::class);

    self::assertNull($runtime->renderForConsole(new ConsoleOutput(), new \Exception()));

    $container->singleton(IRuntime::class, static function () use ($runtime) {
        return $runtime;
    });

    $config = $this->createMock(IConfig::class);
    $config->method('get')->willReturn('production');
    $container->singleton('config', static function () use ($config) {
        return $config;
    });

    $bootstrap->handle($app);

    $this->assertInstanceof(IContainer::class, $container);
    $this->assertInstanceof(Container::class, $container);
    $this->assertInstanceof(IApp::class, $app);
    $this->assertInstanceof(Apps::class, $app);

    $e = new \Exception('foo.');

    self::assertNull($this->invokeTestMethod($bootstrap, 'setExceptionHandler', [$e]));

    $error = new \Error('hello world.');

    self::assertNull($this->invokeTestMethod($bootstrap, 'setExceptionHandler', [$error]));
    $this->restoreSystemEnvironment();
}

register_shutdown_function 设置请求关闭处理函数

public function testRegisterShutdownFunction(): void
{
    $bootstrap = new RegisterExceptionRuntime2();

    $container = Container::singletons();
    $app = new App4($container, $appPath = __DIR__.'/app');

    set_error_handler('var_dump', 0);
    trigger_error('hello error');
    restore_error_handler();

    $this->setTestProperty($bootstrap, 'app', $app);
    self::assertNull($this->invokeTestMethod($bootstrap, 'registerShutdownFunction'));
    self::assertSame($GLOBALS['testRegisterShutdownFunction'], 'hello error');
    unset($GLOBALS['testRegisterShutdownFunction']);
}
