read config

Error message

read config

What it means

A test-only expect("read config") panic: fs::read_to_string on the config file returned an Err. In these tests it fires when the file the test just wrote (or that ConfigStore was expected to write) is missing, unreadable, or not valid UTF-8 — i.e. the test's setup or the save under test did not produce the expected file on disk.

Solutions

1. Check that the preceding write/save actually succeeded and targeted the same path
2. Verify the expected file path matches where the code under test writes (file name, directory, symlinks)
3. If the file exists but is invalid UTF-8, fix whatever produced non-UTF-8 bytes
