That would be a denial of service attack... Typically you do not need to test every page in a web application. Even for very large websites it is usually good enough to test just a few of each type of page. Product Pages, Category Pages, Support Pages, Blog Post Pages etc...
You may want to make exceptions for pages presenting different types of content... for example product pages with video versus product pages without. Or product pages with lots of images versus product pages with only a few. Etc.
