testFilesWithoutAnExtension

tcmts.cli.test.e2e.files.testFilesWithoutAnExtension · #rd4vd7zo · term

A file without an extension (Dockerfile, Makefile) or a hidden one (.gitignore) is kept as written, not read as code: added into a namespace, written out by tcm edit under its own name (a hidden one's dot and all), checked and saved back with --into, patched, and exported as it's named.
