 ## RoadMap
 - [x] Support code coverage collection for system testing.
 - [ ] Support develop mode towards accurate testing.
-- [ ] Support code coverage diff based on Pull Requst.
+- [ ] Support code coverage diff based on Pull Request.
 - [ ] Support code coverage counters clear for the services under test at runtime.
 - [ ] Optimize the performance costed by code coverage counters.
