In a terminal, running: bundle exec rspec runs all my tests in ./spec and they all pass.
In the Testing pane of VS Code, I run some tests and they pass but appear visibly to have failed.  See the image below and note the 1 example, 0 failures

I have this in the development group of my Gemfile:
  gem "ruby-lsp", "~> 0.14.3"
  gem "ruby-lsp-rspec", "~> 0.1.10"
