Autotests help to minimize resources and time spent on application testing. We keep working on creating automated tools that can constantly test applications and report the discovered bugs. In that way we can replicate the errors and fix them. Errors are monitored for every application we develop. The distinctive features of automated testing are these:

	Autotests are compiled inside the application
	Application is tested on a wide range of possible values
	The validation logic is tested on both - Client and Server sides
	Different kinds of testing are applied: stress testing; memory leaks testing; testing in multi-thread mode (that's especially applicable to web applications that are continuously used by many people)
	Test applications can emulate users' input, pages switching, forms, tabs, etc.

Autotests by their type can be categorized as internal and external tests.

During the development phase an application is built in a special way which involves additional internal checking and warnings. Our applications are designed so that the testing process could be run in background mode. Internal testing helps to catch the majority of errors that appear during the development process.

Independent test applications are used to process special tasks such as:

	Finding broken links
	Checking whether a site is working and properly responding
	Network status monitoring
	SQL monitoring for long-running and complicated queries

All our applications are tested in different environments. If we know the customer's environment, we try to setup and develop the application in the same environment. The improved reliability of our applications is the result of this approach.
