Unit tests for HTML output?

Question

It may be a dumb question, but do you do unit tests to output the HTML of your PHP functions / scripts?

I'm trying to keep my HTML and my PHP separate - that is, HTML includes placeholders and functions for certain repeating elements (tabular data / any kind of loop output), but I'm not sure how to do this.

Is there a standard way to solve such problems, or is it mainly a matter of using standard unit tests for functions that create inserted content, and then to make sure that it looks correct in the / W 3C Validator browser?

Thank.

Edit: I think the consequence of this would be: are there any similar tests that even deserve attention? If you correctly separate your content and structure, then you really will only test a few inclusions in very limited scenarios (presumably, anyway). Does it really stand on the full pages of full hands to have a file for comparison?

Answer 1

Based on my experience in testing HTML, I now follow these three basic rules:

1. Do not check the HTML result for the correct template. You modify the HTML output too often, and you end up wasting time saving your tests.

2. HTML. HTML ( HTML, ), HTML . : , , - HTML. , № 1.

3. , HTML. HTML, , , . , .

PHP HTML5. Validator.nu. PHPUnit .

, :

$validator=new HTML5Validate();

// Validate (returns TRUE or FALSE)
$result=$validator->Assert('<p>Hello World</p>'); 

// Get explanation of what wrong (if validation failed)
print $validator->message;
