Unit tests and parsing
Code makes many decisions before and after the model. These tests check that code. The results are from the build of
this site.
168 of 168 unit tests pass.
Tables the extension skips
Before any question goes to the model, code drops tables that are not data. The model never sees these tables, thus no
check above covers them. The browser tests check each rule on a synthetic page.
- Tables marked
role="presentation", and tables that contain other tables: page layout. - Tables in an editable region, because an editor would save the shading with the document.
- App lists, such as a mail inbox. Such a table is marked
role="grid", has a checkbox or button in every
row, and has no header row. All three must be true. A data grid with a header row is still shaded, even with a
checkbox in every row. - Tables with fewer than two rows or two columns.
Parsing
The parser changes cell text into numbers and dates. Each row below is the output of parseNumber and parseDate during the build. Text that is not clear becomes no value, thus it cannot change a scale.
