constellation has its own testsuite, in [tests/tester/main.rs]. It can be invoked with:
cargo test
The testsuite can be run under valgrind's memcheck tool like so:
valgrind --tool=memcheck --trace-children=yes --gen-suppressions=yes --quiet --child-silent-after-fork=yes --trace-children-skip=\*cargo target/debug/test
--trace-children=yes ensures that child processes are also run under valgrind
--gen-suppressions=yes ensures that valgrind pauses execution on detecting an error
--quiet and --child-silent-after-fork=yes disable printing of valgrind/memcheck informational output which the tests do not expect
--trace-children-skip=\*cargo disables valgrind for the invocation of cargo build under the hood.
