 Vim can be tested after building it, usually with "make test".
 The tests are located in the directory "src/testdir".
 
-There are several types of tests added over time:
-	test33.in		oldest, don't add any of these
-	test_something.in	old style tests
-	test_something.vim	new style tests
-
 						*new-style-testing*
-New tests should be added as new style tests.  These use functions such as
-|assert_equal()| to keep the test commands and the expected result in one
-place.
-						*old-style-testing*
-In some cases an old style test needs to be used.  E.g. when testing Vim
-without the |+eval| feature.
+New tests should be added as new style tests.  The test scripts are named
+test_<feature>.vim (replace <feature> with the feature under test). These use
+functions such as |assert_equal()| to keep the test commands and the expected
+result in one place.

-" Commands for recording the execution path.				    {{{2
-"
-" The Xpath/Xloop commands can be used for computing the eXecution path by
-" adding (different) powers of 2 from those script lines, for which the
-" execution should be checked.  Xloop provides different addends for each
-" execution of a loop.  Permitted values are 2^0 to 2^30, so that 31 execution
-" points (multiply counted inside loops) can be tested.
-"
-" Note that the arguments of the following commands can be generated
-" automatically, see below.
-"
-" Usage:								    {{{3
-"
-"   - Use XpathINIT at the beginning of the test.
-"
-"   - Use Xpath to check if a line is executed.
-"     Argument: power of 2 (decimal).
-"
-"   - To check multiple execution of loops use Xloop for automatically
-"     computing Xpath values:
-"
-"	- Use XloopINIT before the loop.
-"	  Two arguments:
-"		- the first Xpath value (power of 2) to be used (Xnext),
-"		- factor for computing a new Xnext value when reexecuting a loop
-"		  (by a ":continue" or ":endwhile"); this should be 2^n where
-"		  n is the number of Xloop commands inside the loop.
-"	  If XloopINIT! is used, the first execution of XloopNEXT is
-"	  a no-operation.
-"
-"       - Use Xloop inside the loop:
-"	  One argument:
-"		The argument and the Xnext value are multiplied to build the
-"		next Xpath value.  No new Xnext value is prepared.  The argument
-"		should be 2^(n-1) for the nth Xloop command inside the loop.
-"		If the loop has only one Xloop command, the argument can be
-"		omitted (default: 1).
-"
-"	- Use XloopNEXT before ":continue" and ":endwhile".  This computes a new
-"	  Xnext value for the next execution of the loop by multiplying the old
-"	  one with the factor specified in the XloopINIT command.  No Argument.
-"	  Alternatively, when XloopINIT! is used, a single XloopNEXT at the
-"	  beginning of the loop can be used.
-"
-"     Nested loops are not supported.
-"
-"   - Use Xcheck at end of each test.  It prints the test number, the expected
-"     execution path value, the test result ("OK" or "FAIL"), and, if the tests
-"     fails, the actual execution path.
-"     One argument:
-"	    Expected Xpath/Xloop sum for the correct execution path.
-"	    In order that this value can be computed automatically, do the
-"	    following: For each line in the test with an Xpath and Xloop
-"	    command, add a comment starting with "X:" and specifying an
-"	    expression that evaluates to the value contributed by this line to
-"	    the correct execution path.  (For copying an Xpath argument of at
-"	    least two digits into the comment, press <C-P>.)  At the end of the
-"	    test, just type "Xcheck" and press <Esc>.
-"
-"   - In order to add additional information to the test output file, use the
-"     Xout command.  Argument(s) like ":echo".
-"
-" Automatic argument generation:					    {{{3
-"
-"   The arguments of the Xpath, XloopINIT, Xloop, and Xcheck commands can be
-"   generated automatically, so that new tests can easily be written without
-"   mental arithmetic.  The Xcheck argument is computed from the "X:" comments
-"   of the preceding Xpath and Xloop commands.  See the commands and
-"   abbreviations at the beginning of this file.
-"

-"     XpathINIT, Xpath, XloopINIT, Xloop, XloopNEXT, Xcheck, Xout.
