+# psenv-test
+
+Used for testing the psenv-rails gem to validate.
+
+## Usage
+
+* Generate new parameter store variable in AWS
+  * `/psenv/test/API_KEY` with value "api_key_value"
+* `PARAMETER_STORE_PATH=/psenv/test bundle exec rails test`
+
+## New Versions
+
+To test new versions of the gem, you can install the psenv-rails gem locally and
+reference it:
+
+1. Clone psenv and complete work
+    1. Likely updating Railtie requirements
+1. Update psenv lib/psenv/version.rb
+    1. Example version name: `0.5.16-local`
+1. Run `bundle exec rake install` in psenv directory
+1. Note new gem version installed locally
+    1. Example gem version: `0.5.16.pre.local`
+1. Open psenv-test project
+1. Update Gemfile with test version
+    1. `gem 'psenv-rails', '0.5.16.pre.local'`
+    1. `bundle install`
+1. `PARAMETER_STORE_PATH=/psenv/test bundle exec rails test`
