Last verified: 2018-08-08 (update history)

Fast Bazel C++ coverage (tracking issue) (P0)

Currently C++ coverage is 2x slower than just running the corresponding tests. The goal is to have similar times for running bazel test and bazel coverage on the same targets.

Objectives:

  • C++ coverage with clang uses profdata and outputs lcov (tracking issue) IN PROGRESS
  • C++ coverage with gcc uses gcov and outputs lcov (tracking issue) DONE

Have a reliable Bazel coverage report (P1)

Objectives:

  • [C++] Fix symlinks following in the coverage report. IN PROGRESS
  • [sh] Improve sh_test coverage (tracking issue) DONE
  • [Java] Improve Java coverage (tracking issue) IN PROGRESS

Improve adding coverage support for Skylark rules (P2)

Objectives:
