Previous articles have described how to use Apacheant to execute the Jacoco tool, and here's how to use MAVEN to use the Jacoco tool.

Background introductionIn conjunction with the Cpputest Unit Test framework, Lcov provides a relatively complete set of engineering tools to measure UT coverage. But for some teams, the history burden is too heavy, and a lot of legacy code does not have the corresponding UT. In this case, a coverage check of the new code

In addition, a breakpoint setting function needs to be defined for the target operating system, because some hardware platforms provide debugging traps to generate specific exceptions (debug traps) breakpoint commands to support debugging (such as x86 INT 3), while other machines do not have similar commands, they are replaced by any illegal (Reserved) co
when I tried to investigate a defect, usually the first thing that I want to verify is the "RunTime" execution flow. and if the "RunTime" flow didn't match the "expected" flow, I wocould be very close to the root cause of a defect. however, sometimes it's not very easy to tell the "real/RunTime" execution flow (especially when you can't attach your debugger to the target assembly, or when the defect can't be reproduced stably ). I used to add more debug info output to the logs to help me out, an
