(Tested only on Ubuntu 18.04 & 20.04)

run-all-tests.sh - call all of your tests here

There are 3½ variants of toolsets to pick from:

1. coverage-grcov.sh

   *.profraw ---> [grcov] +--------------> HTML
                          |   
                          +--> [lcov] ---> HTML
   

2. coverage-llvm.sh

   *.profraw ---> [llvm-profdata] ---> [llvm-cov] ---> [lcov] ---> HTML
   

3. coverage-gcov.sh

   *.gcda/*.gcno ---> [gcov] ---> [lcov] ---> HTML
   

Dependencies:

All: rustup install nightly

Toolset specific:

1. coverage-grcov.sh

   llvm >= v11.0

   If needed: update-alternatives-clang.sh to force the default llvm version

   rustup component add llvm-tools-preview --toolchain nightly

   cargo install grcov

   Optionally: apt-get install lcov

   When in doubt: more about grcov

2. coverage-llvm.sh

   llvm >= v11.0

   If needed: update-alternatives-clang.sh to force the default llvm version

   cargo install rustfilt

   apt-get install lcov

   When in doubt: this chapter of Rust unstable .

3. coverage-gcov.sh

   apt-get install gcc-7 lcov
