File not found: ${path}

Error message

File not found: ${path}

What it means

The in-memory FileSystemTestHelper.readFile was asked for a path never created via createFile — the files Map has no entry for it. This is the helper's stand-in for fs ENOENT: the test is reading a file it did not set up.
