#### Running tests

Run all tests

`$ rake test`

Run a single test suite

`$ rake test TEST=path/to/test.rb`

Run a single test

`$ rake test TEST=path/to/test.rb TESTOPTS="--name=test_something"`

Run tests against different Rails versions by setting the RAILS_VERSION variable
and bundling gems.  (save this script somewhere executable and run from top of AMS repository)

```bash
#!/usr/bin/env bash

rcommand='puts YAML.load_file(".github/workflows/ci.yml").dig("jobs", "test", "strategy", "matrix", "include").map{|v| v["ruby-version"]}.join(" ")'
versions=$(ruby -ryaml -e "$rcommand")

for version in ${versions[@]}; do
  export RAILS_VERSION="$version"
  rm -f Gemfile.lock
  bundle check || bundle --local || bundle
  bundle exec rake test
  if [ "$?" -eq 0 ]; then
    # green in ANSI
    echo -e "\033[32m **** Tests passed against Rails ${RAILS_VERSION} **** \033[0m"
  else
    # red in ANSI
    echo -e "\033[31m **** Tests failed against Rails ${RAILS_VERSION} **** \033[0m"
    read -p '[Enter] any key to continue, [q] to quit...' prompt
    if [ "$prompt" = 'q' ]; then
      unset RAILS_VERSION
      exit 1
    fi
fi
  unset RAILS_VERSION
done
```
