| michael@0 | 6 | // Test Summary: |
| michael@0 | 7 | // 1. Open about:sessionrestore where formdata is a JS object, not a string |
| michael@0 | 8 | // 1a. Check that #sessionData on the page is readable after JSON.parse (skipped, checking formdata is sufficient) |
| michael@0 | 9 | // 1b. Check that there are no backslashes in the formdata |
| michael@0 | 10 | // 1c. Check that formdata doesn't require JSON.parse |
| michael@0 | 11 | // |
| michael@0 | 12 | // 2. Use the current state (currently about:sessionrestore with data) and then open that in a new instance of about:sessionrestore |
| michael@0 | 13 | // 2a. Check that there are no backslashes in the formdata |
| michael@0 | 14 | // 2b. Check that formdata doesn't require JSON.parse |
| michael@0 | 15 | // |
| michael@0 | 16 | // 3. [backwards compat] Use a stringified state as formdata when opening about:sessionrestore |
| michael@0 | 17 | // 3a. Make sure there are nodes in the tree on about:sessionrestore (skipped, checking formdata is sufficient) |
| michael@0 | 18 | // 3b. Check that there are no backslashes in the formdata |
| michael@0 | 19 | // 3c. Check that formdata doesn't require JSON.parse |
