removed test param 'appClass' as it does not make sense to configure
application class for all tests, some explicitly need webapp where
some might explicitly need console app.
* 'unittest-app-dependency' of https://github.com/bwoester/yii2:
mod: incorporate suggestions - rename requireApp() to mockApplication() - always destroy app on tearDown() - eliminates need for constant YII_DESTROY_APP_ON_TEARDOWN - mockApplication() becomes a lot easier. Destroying app on each tearDown means creating it on every call is fine. No more checking if it already exists and if it has been created from the same config. - \yii::$app should have been \Yii::$app
add: new key for unit tests config named "className". Allows to run the tests using different Application instances (consoleApp/ webApp) mod: TestCase::getParam accepts second param $default=null
mod: don't create app in bootstrap script, unit tests do it themselves add: option to destroy app after each test to find unit tests that fail to require an app
allow unit tests to requireApp() on setUp()
