%% Item:
%% Test suite for the verb substitution task in pre_process.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% Bug description (add references to further descriptive files if possible):
%% In LaTeX, \begin{environment} opens a group which is ended by
%% \end{environment}, making definitions or font changes local within
%% this group. This was not seen by l2h.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% Bug caused this behaviour (may be several descriptions):
%% Changes to the font (style, size) made within the environment are not
%% reverted after the environment closed.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% Bug severity (low|bothers|problematic|urgent -- fixed|open -- message):
%% bothers -- fixed --
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%% Test suite decription:
%% The suite focuses on the substitution statements of the task in pre_process().
%% We have the following equivalence classes (written in perl style):
%%
%% $del, $dels, $deln are meta variables for delimiters.
%% Important: In this notation the dot (.) includes the newline (\n).
%%
%%
%% a): \\verb[a-zA-Z].*
%%	not a \verb statement
%%	Hint: \\verb[$del][^$del]*[$del] with $del in [a-zA-Z] was falsely
%%	expanded in previous revisions.
%%
%% b): \\verb\*.*
%%	$del be a char in [^\t \n]
%%
%%     b1): \\verb\*\t*[$del][^$del]*[$del].*
%%	\verb statement
%%	$del may be escaped by &escape_rx_chars or not, hence the subclasses:
%%       b11): $del is \w
%%       b12): $del is \W
%%
%%     b2): \\verb\*\t*[$del][^$del]*
%%	not a \verb statement
%%
%%     b3): \\verb\*\t*[ \n].*
%%	not a \verb statement
%%
%%     b1) or b2) or b3) => b)
%%
%% c): \\verb[^a-zA-Z*\t \n].*
%%     <=>
%%     \\verb[$del].*  iff $del in [^a-zA-Z*\t \n]
%%
%%     c1): \\verb[$del][^$del]*[$del].*
%%	\verb statement, $del may be escaped by &escape_rx_chars or
%%	not. Hence the subclasses:
%%	c11): $del is \w
%%	c12): $del is \W
%%
%%     c2): \\verb[$del][^$del]*
%%	not a \verb statement
%%
%%	c1) or c2) => c)
%%
%% d): \\verb\t.*
%%	$dels be in [^ \n\t], $deln be in [^ \n\t*]
%%	d1): \\verb\t\t*\*.*
%%	    d11): \\verb\t\t*\*\t*[$dels][^$dels][$dels].*
%%	    \verb statement, $dels may be escaped by &escape_rx_chars
%%	    or not. Hence the subclasses:
%%		d111): $dels is \w
%%		d112): $dels is \W
%%	    d12): \\verb\t\t*\*\t*[$dels][^$dels]*
%%	    not a \verb statement
%%	    d13): \\verb\t\t*\*\t*[ \n].*
%%	    not a \verb statement
%%
%%	d2): \\verb\t\t*[$deln].*
%%	    d21): \\verb\t\t*[$deln][^$deln][$deln].*
%%	    \verb statement, $deln may be escaped by &escape_rx_chars
%%	    or not. Hence the subclasses:
%%		d211): $deln is \w
%%		d212): $deln is \W
%%	    d22): \\verb\t\t*[$deln][^$deln]*
%%	    not a \verb statement
%%
%%	d3): \\verb\t\t*[ \n].*
%%	not a \verb statement
%%
%%	d1) or d2) or d3) => d)
%%
%% e): \\verb[ \n].*
%%	not a \verb statement
%%
%% a) or b) or c) or d) or e) => \\verb.*
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% Expected output of this suit:
%% tex: \verbxtestax = undefined control sequence
%% l2h: \verbxtestax = unknown command
%% html output should look like dvi output

%%% The Tests matching the equivalence classes.
%%% Commented-out tests don't run in LaTeX, so testing seems
%%% to be obsolete there.
%%% Note: Test cases should contain zero, one or more tabs,
%%% zero, one or more chars of verb contents and several
%%% combinations of failure and success test cases.


%%% Tests for a):

%%% false delimiter, should fail
\verbxtestax


%%% Tests for b):
%%% b11): correct \w delimiter, should pass
\verb*xtestb11x

\verb*	xtestb11x

\verb*		xtestb11x

%%% b12): correct \W delimiters, should pass
\verb*/testb12/

\verb**testb12*

\verb*\testb12\

%%% b2): no closing delimiter, should fail
%\verb*xtestb2

%%% b3): no delimiter, should fail
%testb3\verb*


%%% Tests for c):
%%% c11): correct \w delimiter, should pass
\verb_testc11_

%%% c12): correct \W delimiter, should pass
\verb/testc12/

%%% c2): no closing delimiter, should fail
%\verb_testc2


%%% Tests for d):
%%% d111): correct \w delimiter for \verb\t\t*\*, should pass
\verb	*_testd111_

\verb	*	_testd111_

\verb		*	_testd111_

%%% d112): correct \W delimiter for \verb\t\t*\*, should pass
\verb	*/testd112/

\verb	**testd112*

%%% d12): no closing delimiter for \verb\t\t*\*, should fail
%\verb	*_testd12

%%% d13): no delimiter for \verb\t\t*\*, should fail
%testd13\verb	*

%%% d211): correct \w delimiter for \verb\t\t*, should pass
\verb	xtestd211x

%%% d212): correct \W delimiter for \verb\t\t*, should pass
\verb	/testd212/

%%% d22): no closing delimiter for \verb\t\t*, should fail
%\verb	/testd22

%%% d3): no delimiter for \verb\t\t*, should fail
%testd3\verb	


%%% Tests for e):
%teste\verb


%%% Missing: combinatoric tests.


%%% Stress tests (should pass):
\verb		*			/x
y\
test1
