Testing templates without creating a page using TemplateMock

Sometimes it’s useful to test your code before committing it. When possible unit tests make for a nice way to do this. Template code, however, is not always the most easy to test as a unit. This is when a UI testing framework such as Selenium can come in handy. Unfortunately creating the pages to test can be a bit cumbersome and this is where TemplateMock helps out.


TemplateMock allows you to access a page type without creating it in edit mode from a known URL. After adding templateMock to your site you can render a standard page using an alternative url:




When navigating to TemplateMock without query parameters you can choose which template to execute:


Optionally you can add query parameters to configure it:

randomize (true/false): Wheter the content on the page is deterministic (doesn’t change every time)

numberOfChildren (0-n): How many children this page appears to have

For example “/TemplateMock.ashx?scenario=[Public]+Standard+page&randomize=false&numberOfChildren=100” will render a standard page with 100 child pages without randomizing it’s content.

It’s also possible to tweak other aspects from code. This is left as an excercise to the reader.

Download & installation

Be aware that TemplateMock broadcasts unsupported pirate signals to hack into the CMS core and should never be used in production.

To install it just unzip in your site’s root directory and navigate to TemplateMock.ashx.

This looks like a very interesting concept. We run EPiServer from the command line for unit testing so this looks like a useful addition to the testing tools out there!

Any chance you can upload the source code as well? Preferably to GitHub or some other place where it's easily forkable :)
