Ah! I couldn't figure them out. Thanks!

+PASS WebAuthentication interface: existence and properties of interface object 
+PASS WebAuthentication interface object length 
+PASS WebAuthentication interface object name 
+FAIL WebAuthentication interface: existence and properties of interface prototype object assert_equals: class string of WebAuthentication.prototype expected "[object WebAuthenticationPrototype]" but got "[object WebAuthentication]"
+PASS WebAuthentication interface: existence and properties of interface prototype object's "constructor" property 
+PASS WebAuthentication interface: operation makeCredential(Account,[object Object],BufferSource,ScopedCredentialOptions) 
+PASS WebAuthentication interface: operation getAssertion(BufferSource,AssertionOptions) 
+PASS WebAuthentication must be primary interface of navigator.authentication 
+PASS Stringification of navigator.authentication 
+PASS WebAuthentication interface: navigator.authentication must inherit property "makeCredential" with the proper type (0) 
+PASS WebAuthentication interface: calling makeCredential(Account,[object Object],BufferSource,ScopedCredentialOptions) on navigator.authentication with too few arguments must throw TypeError 
+PASS WebAuthentication interface: navigator.authentication must inherit property "getAssertion" with the proper type (1) 
+PASS WebAuthentication interface: calling getAssertion(BufferSource,AssertionOptions) on navigator.authentication with too few arguments must throw TypeError
