Rez currently has a lot of tests, but our test coverage is only 60% at the time of writing this. Coverage can be visualized at https://app.codecov.io/gh/AcademySoftwareFoundation/rez/tree/main/. The goal here is to add tests to cover critical pieces and help us reach at least 80% coverage. Critical parts that need immediate attention, in no particular order: src/rezplugins/release_vcs (particularly the git plugin) src/rezplugins/release_hook (this currently has no tests). src/rez/package_cache.py (some tests, but could have more) src/rez/package_search.py (no tests) src/rez/package_test.py (has a few tests, but we need way more) src/rez/resolved_context.py (this is probably the part that needs the most attention with its 56% coverage) src/rez/utils (these will be easy wins because most of the code under that package is relatively easy to test) Also critical, but much harder to test: src/rez/resolver.py and src/rez/solver.py (this is the brain. We have some solver tests, but we need
On Windows, environment variable keys are case-insensitive for lookup and assignment; Python's wrapper for os.environ hides this away behind a Mapping interface that normalizes keys to uppercase internally. However, the rex bindings that expose the environment to packages do not handle a provided parent_environ dict in a similarly case-insensitive way on Windows. Thus, if a case-sensitive mapping is provided for parent_environ (e.g. by copying and modifying os.environ), and a package tries to look up an environment variable that is present in parent_environ but uses a different casing than parent_environ's entry, it will error similarly to: Error in commands in package '...': Referenced undefined environment variable: SomeVariable This error does not occur when a parent_environ override is not provided, as rex will fall back to binding os.environ, and thus lookups will be appropriately case-insensitive on Windows.
