+# Gilded Rose in Java with Approval Tests
+
+This folder has a unit test that uses [Approvals](https://github.com/approvals/approvaltests.java)
+
+There are two test cases here with different styles:
+
+* "foo" is more similar to the unit test from the 'Java' version
+* "thirtyDays" is more similar to the TextTest from the 'Java' version
+
+I suggest choosing one style to develop and deleting the other.
