     11 // Here's the set-up for this test:
     12 // Step 1. (window) set up listeners for main window.
     13 // Step 2. (iframe1 & iframe2) loads and sends "iframe loaded" message.
     14 // Step 3. (window) receives two "iframe loaded" message and sends "create database" message to iframe1.
     15 // Step 4. (iframe1) receives "create database", creates database, and sends "database created" message.
     16 // Step 5. (window) receives "database created" message and sends "check database" message to iframe2.
     17 // Step 6. (iframe2) receives "check database" message, checks if database exists, sends "database checked" message.
     18 // Step 7. (window) receives the "database checked" message, asserts database existed, and then exits.
