求翻译：用例组更重要的作用是为了从逻辑上分类和管理用例。测试集的作用是将准备一起执行的用例放在一块。测试集是用例执行的最小单位。是什么意思？

Use case set a more important role is to logically classify and manage use cases. The role of the test set is ready to perform together on a use case. Test set is the smallest unit of execution with the case.

For example Group is a more important role in order to logically use classification and management. The Group is testing the role will be ready to work together to implement a piece of legislation in place. The Group is a test case for the smallest unit of implementation.

Is in order to classify and the management logically with an example group more vital role uses the example.The test collection function is prepares to carry out together places with the example at the same place.The test collection is the smallest unit which carries out with the example.

Use case group is even more important role in logic, classify, and manage cases. Testing role is to prepare the implementation of the set of use cases together. Test set is the smallest unit case execution.
