 - `ACContextHistoryTyped`: Perform above test.
 - `ACContextHistoryMultiple`: **B** Broadcasts multiple history items of both types.  Ensure that only the last version of each type is received by **A**.
 - `ACContextHistoryLast`: In step 5. **A** retrieves the _untyped_ current context of the channel via `const currentContext = await testChannel.getCurrentContext()`. Ensure that A receives only the very last broadcast context item _of any type_.
+- `ACClearHistorySpecificContext`: Perform the above test, except after step 3 clear context with `await testChannel.clearContext('fdc3.instrument')`. Ensure that in step 5 nothing is received for `const instrument = await testChannel.getCurrentContext('fdc3.instrument')` and context is received successfully for `const instrument = await testChannel.getCurrentContext('fdc3.contact')`
+- `ACClearHistoryAllContexts`: Perform the above test, except after step 3 clear context with `await testChannel.clearContext('fdc3.nothing')`. Ensure that in step 5 nothing is received for `const instrument = await testChannel.getCurrentContext('fdc3.instrument')` and for `const instrument = await testChannel.getCurrentContext('fdc3.contact')`
+- `ACClearHistoryAllContextsSubscribedToNothing`: Perform the above test, except after step 3 clear context with `await testChannel.clearContext('fdc3.nothing')` and in step 4 call `await testChannel.addContextListener("fdc3.nothing", handler)` instead. Ensure that after clearing context, the handler is called.
