////////////////////////////////////////////////////////////////////////////
//
// Test utility
//
// The test function accepts a file loaded in memory. The 'test_file'
// range param points to the data contained in the file. This file
// contains two parts.
//
// 1) The source input for testing
// 2) The expected result.
//
// The first part of the file is sent to the generator function
// 'gen' which returns a string. This generated string is then compared
// to the contents of the second (expected result) part.
//
// The second part is demarcated by the string parameter 'demarcation'
// which defaults to "<**expected**>". The expected template may include
// embedded regular expressions marked-up within re_prefix and re_suffix
// parameter tags. For example, given the default RE markup ("<%" and
// "%>"), this template:
//
// <%[0-9]+%>
//
// will match any integer in the source input being tested. The function
// will return the first non-matching position. The flag full_match
// indicates a full match. It is possible for returned pos to be
// at the end of in (in.end()) while still returning full_match ==
// false. In that case, we have a partial match.
//
// Here's an example of a test file:
//
// Hello World, I am Joel. This is a test.
//
// <**expected**>
// Hello World, I am <%[a-zA-Z]+%>. This is a test.
//
