Ideally, at the end of this exercise you should be able to understand your users’ interests and motivations better, and hone in on a small group of people who feel enough pain to buy your product.
Also, if done right, you’ll be able to use what you’ve learned to find similar (or parallel) markets to expand into in the future.
The goal of validating demand is to get an answer to the question: Here, you want to work out a realistic market size that is feasible, otherwise you risk there not being enough demand for the product because it doesn’t solve a big enough problem for its market or it doesn’t solve the problem in a way that works well for users.
You want to ensure that the market is big enough and that there are enough people willing to pay for your product or service.
However, in the previous example the validator XML file, validator.xml, does not provide validators for all of the form fields in the Registration Form.
There are no required external dependencies at all!
When surveyed, a large majority of Web professionals will state that validation errors is the first thing they will check whenever they run into a Web styling or scripting bug.
Checking that a page “displays fine” in several contemporary browsers may be a reasonable insurance that the page will “work” today, but it does not guarantee that it will work tomorrow.
The project can be found on Git Hub where you can also find our issue tracker.
There is also a Travis project used for testing, a Coveralls project used to code coverage as well as the annotated source.
