### LSP tests

LSP tests run target language tools to lint and find errors in target code such as reaction bodies.
They work by inserting errors into files in this directory, running LFC on them in LSP mode, and
verifying that errors are reported correctly. When a test fails, an error message is printed that
explains why; such an error message will include the string "the expected error could not be found."
The contents of the altered LF file (including the inserted error) are printed, with an arrow `->`
marking the line on which an error message should have been reported.
