 ## Test MockApi pattern
 
-Every test module that implements `BacklogApi` on a `MockApi` **must include ALL trait methods**.
-Use `unimplemented!()` for methods not under test:
+`BacklogApi` has default `unimplemented!()` bodies for all methods, so a
+`MockApi` only needs to override the methods actually exercised by the test.
+Do **not** add `unimplemented!()` stubs for unused methods — the default fires
+automatically.
 
 ```rust
 struct MockApi { data: Option<MyResource> }
 
 impl BacklogApi for MockApi {
-    fn get_space(&self) -> Result<Space> { unimplemented!() }
-    fn get_myself(&self) -> Result<User> { unimplemented!() }
-    fn get_space_activities(&self) -> Result<Vec<Activity>> { unimplemented!() }
-    fn get_my_resource(&self) -> Result<MyResource> {
+    fn get_my_resource(&self, _params: &[(String, String)]) -> Result<MyResource> {
         self.data.clone().ok_or_else(|| anyhow!("no data"))
     }
 }
 ```
 
-Forgetting a method causes a compile error.
+When a test calls a method that isn't overridden, it will panic with
+`not implemented` — which is the desired behavior (it means the test is
+exercising an unexpected code path).
