+Feature: Flagd Provider State Changes
+
+  Background:
+    Given a flagd provider is set
+
+  Scenario Outline: Provider events
+    When a <event> handler is added
+    Then the <event> handler must run
+    Examples:
+      | event                          |
+      | PROVIDER_ERROR                 |
+      | PROVIDER_STALE                 |
+      | PROVIDER_READY                 |
+
+  Scenario: Provider events chain ready -> stale -> error -> ready
+    When a PROVIDER_READY handler is added
+    Then the PROVIDER_READY handler must run
+    When a PROVIDER_STALE handler is added
+    Then the PROVIDER_STALE handler must run
+    When a PROVIDER_ERROR handler is added
+    Then the PROVIDER_ERROR handler must run
+    When a PROVIDER_READY handler is added
+    Then the PROVIDER_READY handler must run
