public class ContinuousTestGeneration
extends Object

This is the main entry point for the new paradigm "Continuous Test Generation" (CTG). This can be called directly from EvoSuite for experiment reasons, but its usage for practitioners will be based on build environments like Maven/Ant and continuous integration environments like Jenkins/Hudson/Bamboo

In a nutshell, the idea is for a project to keep track/store the best test suite for each class in the project. Each time CTG is run (and can be run continuously), we try to generate test suites for classes we haven't addressed yet, and we try to improve the current ones (by seeding). Benefits are for example:

• No need to download EvoSuite. This is done automatically with Maven
• Smart allocation of search budget among classes with different size/difficulty
• Very easily configurable to run 24/7, with reports on entire project
• Possibility to reuse test cases/data from one class to help generation of test suites for new classes
• Can automatically check from repository which classes have been modified, and concentrate search on them

CTG can also be configured to "call home". This will be useful to see how EvoSuite is used in practice.

TODO we should also have an option "regression" to run current test suites, and see if any fails. Even if do not want to explicitly do regression, we might still have to run old test cases, as failing ones should be (re)moved and labelled as "regression-failing"

TODO need also option to automatically commit to repository any new, better test
