I too have noticed that some testing practises seem to be particularly optimal for (and preferred by) consultants and agencies working on short-to-mid-term web development projects. When they go on to over-generalise TDD as the one true 'professional' approach to all development on all projects, it can become a little grating though. Like all things, the right level of test coverage and the methodology used to achieve it, are a matter of trade-offs and the right trade-off can vary a lot depending on the type and lifespan of project, the way requirements are gathered and the project is governed, the business goals, the people involved, etc etc etc.
