 ## What are the utility methods
 
 _Utility methods_ implement common, often re-used operations which are helpful for accomplishing tasks in many 
-classes. In UnitTestBot _utility methods_ include those related to creating instances, checking deep

 ## Why to create UtUtils class
 
-Previously UnitTestBot generated _utility methods_ for each test class when they were needed — and only those which were necessary for the given class. They were declared right in the generated test class, occupying space. Generating multiple test classes often resulted in duplicating _utility methods_ and consuming even more space.

 For now UnitTestBot provides a special `UtUtils` class containing all _utility methods_ if at least one test class needs some of them. This class is generated once and the specific methods are imported from it if necessary. No need for _utility methods_ — no `UtUtils` class is generated.
