Testbench\TComponent

Testing UI\Control render

It can be useful to check if rendered string (or HTML template) contains what you wanted. It can be achieved like this (using match method from Nette\Tester)

use \Testbench\TComponent;

public function testComponentRender()
{
	$control = new \Component;
	$this->checkRenderOutput($control, '<strong>OK%A%'); //match string
	$this->checkRenderOutput($control, __DIR__ . '/Component.expected'); //match file content
}

See: https://tester.nette.org/#toc-assert-match

It's also possible to send parameters to the render method via third parameter of checkRenderOutput like this:

use \Testbench\TComponent;

public function testComponentRender()
{
	$control = new \Component;
	$this->checkRenderOutput($control, '<strong>OK%A%', ['OK']);
	$this->checkRenderOutput($control, __DIR__ . '/Component.expected', [1, '2']);
}

If you only need to attach IComponent to the presenter you can use attachToPresenter:

use \Testbench\TComponent;

public function testComponentAttach() {
	$control = new \Component;
	$this->attachToPresenter($control);
}

Component is by default attached to the Testbench\PresenterMock. If you want to change this behavior you can set custom presenter mock in config file:

services:
	testbench.presenterMock: App\CustomPresenterMock
