| On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". |

| First, verify that the database connection is not closed: |

| Database closing steps |
| "1. Set the internal closePending flag of connection to true." |
| connection.close() |
| Expecting exception from connection.transaction('store') |
| PASS Exception was thrown. |
| PASS code is DOMException.INVALID_STATE_ERR |
| PASS ename is 'InvalidStateError' |
| Exception message: Failed to execute 'transaction' on 'IDBDatabase': The database connection is closing. |
| "2. Wait for all transactions created using connection to complete. Once they are complete, connection is closed." |

| IDBDatabase.transaction(): |

| PASS Exception was thrown. |

| "versionchange" transaction steps: |

| closePending is set, but active transaction will keep connection from closing |
| request = indexedDB.open(dbname, 3) |
| 'blocked' event fired, letting transaction complete and connection close |
| version_change_connection = request.result |
| PASS versionChangeWasFired is false |
| version_change_connection.close() |
