.gcda files are not getting generated

I am running my coverage.sh script using docker

./coverage.sh --sysroot /home/adam/TOOLCHAIN/sysroots/aarch64-oe-linux/ --img-name artifactory-ab.abcd.com:0023/ut/my_image_docker --img-tag 1234Z

But coverage report shows 0% coverage for all my file.And i also noticed logs (.gcda files are also not generated)

Using gcovr 4.2lines: 0.0% (0 out of 3239)branches: 0.0% (0 out of 4046)

mv: cannot stat '*.gcda': No such file or directory

XML AND HTML REPORTS ARE AVAILABLE @ :: /home/adam/abcd/def/test/unit_test/./../..//build/coverage_report//
