Test coverage is not accurate

[mssun]

Everything works well except for files/functions under shell. I don't why the integration test cases for shell will not emit hit counts. Therefore, the test coverage for posix/sh is not accurate.

Can you test the coverage on the sh-parser branch? It no longer uses nom so I'm curious if that helped at all.

Still zero coverage for parser.rs: https://codecov.io/gh/mesalock-linux/mesabox/tree/373875043044f1f248f48477d3cf19f92fab8273/libmesabox/src/posix/sh

Not sure what the problem is then :/

I found that the libmesabox test (unit tests) reported coverage statistics of parser.rs (though zero coverage because of no unit tests for parser I guess). However, if we only look at the integration tests, here is no report of parser.rs for the integration tests. This is wired. This implies that all symbols of parser.rs are missing and the file is also not included in the report.

Another case is that the parser_num function is explicitly called by tests, but the coverage results show it was not hit. https://codecov.io/gh/mesalock-linux/mesabox/src/master/libmesabox/src/posix/head.rs#L339

With further investigation, I found that functions in validator_os in clap will not be counted.
