Detailed Description

Parses a file containing one or more test case descriptions into a list of TestCase objects. A test file has the following format:

<QUERY string>=""> -— <SECTION NAME 1> <EXPECTED CONTENTS 1> -— <SECTION NAME 2> <EXPECTED CONTENTS 2> -— <SECTION NAME 3>

<EXPECTED CONTENTS 3>

<QUERY string>=""> -— <SECTION NAME 1> <EXPECTED CONTENTS 1> -— <SECTION NAME 2> <EXPECTED CONTENTS 2> -— <SECTION NAME 3>

<EXPECTED CONTENTS 3>

Acceptable section names are ONLY those contained in TestFileParser.Section.

Lines beginning with # or // are comments. Clients can retrieve sections with or without these lines included.

Note that <QUERY string>=""> and <EXPECTED contents>=""> sections can consist of multiple lines.
