Comment:

The test as it stands is not particularly useful as it does not specify the viewport size, which will have an effect on scalability and occurrence of clipped text and text overlapping. It also does not specify what it means that "text size can be increased to 200% of the original size" - is the requirement that the text is still legible / not clipped?

Proposed Change:
If the test is to determine whether enlarged text is still usable / legible (and this is the only meaningful test), the viewport / window size to be used in the test must be specified (WAT and Web developer toolbar allow the setting of the window to 1024 x 768 px, for example), and criteria for compliance must be given (e.g. "the text is still fully legible (i.e. no parts are clipped, boxed do not overlap).

Resolution: Good points. The goal is to increase the text size in the expected viewport size, that is, the viewport size for which the content was designed. Of course, this will depend on the designer's expectations of the devices available to the user. However, the tester has no way to reliably determine those expectations. Using a viewport size that is smaller than expected can produce incorrect failures. For testing purposes, we have selected "1024 x 768 or larger" as the expected viewport size, so the initial step in the procedure is now Set the viewport size to 1024px x 768px or larger". Note that this does not ensure legibility of the text. Depending upon the characteristics of the device and the design of the page, text many be very small physically. However, it gives us a basis on which to compare functionality with the enlarged text version. We have also added an additional test step to clarified what must be true after increasing the text size: Check that after increasing the text size to 200% of the original size, there is no loss of content or functionality (e.g. no parts of the text are clipped, boxes do not overlap, controls are not obscured or separated from their labels, etc)
