# ClassTester - Test automatically all the stuff you don't bother testing with hand written tests

By Roy Osherove August 3, 2007 In [Agile](https://osherove.com/blog/category/agile), [Agile Related](https://osherove.com/blog/category/agile-related), [Art Of Unit Testing](https://osherove.com/blog/category/art-of-unit-testing), [Unit Testing](https://osherove.com/blog/category/unit-testing)

**Historical article** · Originally published August 3, 2007; technical details may be outdated.

A dude named Josh sent me an email about a Class Tester he's developed, [available here](http://www.thejoyofcode.com/Automatically_Unit_Test_your_Model.aspx). The idea is to take care of all the things I usually avoid writing unit tests for because it takes too much effort for too little benefit:

> ##### "What it can do:
>
> -   Automatically test properties, spotting any miswired getters or setters
> -   Increase code coverage, reaching parts manual tests don't even try to
> -   Supports ignoring specified properties if you have any funky logic in there that needs a manual test
> -   Tests for **PropertyChanged** events if your class implements **INotifyPropertyChanged**
> -   Tests constructors and that they map parameters to properties "

Looks pretty cool, and might make a fine addition to the unit testing tool set. Thanks Josh!
