How to write unit tests in Emacs Lisp?
El4r (Emacs Lisp for Ruby) leverages Ruby’s Test::Unit framework by using the EmacsRuby extension language. You write unit tests in EmacsRuby, while the code is in EmacsLisp. In other words, you can treat the EmacsLisp code as a black box and feed it inputs and check the outputs using EmacsRuby.
Is there a way to run tests in Emacs?

What are the features of ERT in Emacs?
ERT is a tool for automated testing in Emacs Lisp. Its main features are facilities for defining tests, running them and reporting the results, and for debugging test failures interactively. ERT is similar to tools for other environments such as JUnit, but has unique features that take advantage of the dynamic and interactive nature of Emacs.
Why does LSP mode slow down my Emacs?
Normally, lsp-ui is very fast but in some systems (especially when using Windows) lsp-ui overlays and popups might slow down emacs. Optional: fine-tune lsp-idle-delay. This variable determines how often lsp-mode will refresh the highlights, lenses, links, etc while you type.
