No data in Coverage Report #938

Open ZhaoZicheng-git opened 1 month ago

ZhaoZicheng-git commented 1 month ago

Hi, I am just using gcovr to general Coverage Report. I can general the html report but no data in report. Like this: image

I have general the gcda and gcno file, and the source file is in the same directory, like this: image The command is : gcovr -v --html-details coverage.html I don't know the reason, please get some suggestions. Thank you.

ZhaoZicheng-git commented 1 month ago

I add some information: gcovr version:7.2 OS: windows 10 compiler: x86_64-8.1.0-release-posix-sjlj-rt_v6-rev0

Spacetown commented 1 month ago

There are some gcov files visible in the screenshot. Did you run gcov on your own or is this a left over from gcovr? In your verbose output there should be some information what's going on.

ZhaoZicheng-git commented 1 month ago

Yes, I run gcov before using gcovr.

Spacetown commented 1 month ago

Yes, I run gcov before using gcovr.

In that case you should use --gcov-use-existing-files but with your current command line gcovr should execute gcov for each file found. Have you checked your log?

Hi ,this is the log: image

Hi, it's always better to copy the text instead if a screenshot. Your file is filtered because it's outside your root directory which is by default the current directory. Try to use --filter .*/src/.*.

ZhaoZicheng-git commented 1 month ago

--filter ./src/.

Thank you.

In your detailed log the filter option wasn’t used. Lines starting with (DEBUG) Filtering coverage data for file show that the filter is not matching a file and the data is ignored.

Hi, Now I can general the canif_test.cpp coverage, but what I want is the srv_canif.c coverage(I use canif_test.cpp to test srv_canif.c). I don't know why. The coverage is as follow: image

The command is: gcovr -v --html-details coverage.html --filter D:/code/imap/src/service/bsw/canif --filter D:/code/imap/unit_test/test_src/ut_canif Here the canif_test.cpp is in ut_canif, srv_canif.c is in canif. Here is the log:
