Evaluating documentation coverage can include identifying, from a testing tool having exercised an application, interface elements of the application's user interface. The identified interface elements are filtered to identify documentable interface objects. For each identified documentable interface object, it is determined if documentation exists for that documentable interface object. A value, indicative of the determined existence or non-existence of documentation, is assigned to each documentable interface object. Documentation coverage data is reported for the application interface. The coverage data is reflective of the values assigned to the documentable interface objects.
