Description

Contest Estimator's module was not able to generate JaCoCo reports due to obsolete gradle.build settings. Also, fuzzer now can generate objects using reflection or mocks to cover cases where only interfaces or abstract classes are expected.

How to test

Manual tests

1. Configure and run Contest Estimator class.
2. After it finishes run task gradle :utbot-junit-contest:test
3. You can find reports in a folder build/reports

NB! If there's several projects with different versions like guava, then report works only for the first one, because all these libraries are loaded by tests. You can manually remove unnecessary folders.
