The unified test driver could do a better job attaching more information to error messages, enabling developers to much more quickly resolve some issues.

For example, in "mongocxx/test/spec/unified_tests/runner.cpp", run_unified_format_tests_in_env_dir() uses CAPTURE() and REQUIRE() as error reporting facilities. This does not provide information about what the error condition /was doing/: looking up an enviornment variable? Trying to find a test_files.txt file? Attaching even a small amount of further information to the thrown exceptions (used by Catch2) would really help.

This ticket is meant to represent incremental improvement, not a final or complete list of projects.
