+Feature: Support autoenv setting
+    When the user sets `sdkman_auto_env=true`, we should always `use` the
+    candidates specified in `./.sdkmanrc`, if any.
+
+    Background:
+        Given SDKMAN! candidate list is up to date
+        And   candidate ant is installed at version 1.9.7
+        And   candidate ant is installed at version 1.9.9

+        And   candidate crash is installed at version 1.2.11
