一个java应用程序的单元测试的遗产不知道record-n-run测试工具

代码说明：

What jrunr is jrunr is a tool that can be used to non-intrusively record and store unit test data from a running instance of an existing java application, which can be reused later on in unit tests. It is specifically intended for use in maintenance scenarios of java applications that are not TDD aware, which as a result cannot be easily unit tested. Why Unit tests play a role in not just from-scratch development projects, but also in maintaining existing applications by providing the test base that can be used to validate new builds, ie, enhancements. However, adding to existing code that is not written in a test-aware fashion makes it difficult to narrow creation of any new test cases to the specific problem that is being fixed. Some of these scenarios are: 1. The code to be tested is a small part of a large method, ie only one of the flows has been modified and needs to be tested. The rest of the code is known to be correct to the extent verified b
