Check if / how to integrate cucumber tests into coverage

Following would be to use cargo-kcov. it was a test to integrate cucumber tests but it seems like kcov fails while reading cucumber

2846error: failed to get coverage
2847caused by: exit code: 1

The following coud be happened to .travis.yml

    &&
    sudo apt-get install cmake g++ pkg-config jq &&
    cargo install --force cargo-kcov &&
    cargo kcov --print-install-kcov-sh | sh &&
    cargo kcov -vV &&
    cargo kcov --verbose --coveralls --all --no-clean-rebuild &&
    echo "Uploaded code coveralls via cargo-kcov"

Start with the failing Travis CI output and inspect .travis.yml, especially the proposed cargo-kcov commands. Reproduce the failure around features/adr_lifecycle and determine whether cargo-kcov can process the Cucumber tests. Done means a documented or working Travis coverage integration that includes the Cucumber tests without the reported parsing error.
