+Feature: flagd selector
+
+  Background:
+    Given an option "selector" of type "String" with value "rawflags/selector-flags.json"
+    And a stable flagd provider
+
+  Scenario Outline: Flags not found
+    Given a <type>-flag with key "<key>" and a default value "<default>"
+    When the flag was evaluated with details
+    Then the reason should be "ERROR"
+
+    Examples:
+      | key          | type    | default |
+      | boolean-flag | Boolean | false   |
+      | string-flag  | String  | bye     |
+      | integer-flag | Integer | 1       |
+      | float-flag   | Float   | 0.1     |
+
+  Scenario: Resolve values
+    Given a String-flag with key "selector-flag" and a default value "foo"
+    When the flag was evaluated with details
+    Then the reason should be "STATIC"
