| PASS observer.observe({entryTypes:[]}) threw exception TypeError: entryTypes cannot be an empty list. |
| PASS observer.observe({entryTypes:["not-real"]}) threw exception TypeError: entryTypes contained only unsupported types. |
| PASS observer.observe({entryTypes:["mark"]}) did not throw exception. |
