+
+Libtool comes with its own set of programs that test its capabilities,
+and report obvious bugs in the libtool program. These tests, too, are
+constantly evolving, based on past problems with libtool, and known
+deficiencies in other operating systems.
+
+As described in the @file{INSTALL} file, you may run @kbd{make check}
+after you have built libtool (possibly before you install it) in order
+to make sure that it has the functionality demanded by the test
+programs.

+@subsection Description of Test Suite
+
+Here is a list of the current programs in the test suite, and what they
+test for:
+
+@table @file
+@item demo-conf.test
+@itemx demo-exec.test
+@itemx demo-inst.test
+@itemx demo-make.test
+@itemx demo-unst.test
+These programs check to see that the @file{demo} subdirectory of the
+libtool distribution can be configured, built, installed, and
+uninstalled correctly.
+
+The @file{demo} subdirectory contains a demonstration of a trivial
+package that uses libtool.
+
+@item hardcode.test
+On all systems with shared libraries, the location of the library can be
+encoded in executables that are linked against it @pxref{Linking
+Executables}. This test checks the conditions under which your system
+linker hardcodes the library location, and guarantees that they
+correspond to libtool's own notion of how your linker behaves.
+
+@item link.test
+This test guarantees that linking directly against a non-libtool static
+library works properly.
+
+@item link-2.test
+This test makes sure that files ending in @samp{.lo} are never linked
+directly into a program file.
+
+@item suffix.test
+When other programming languages are used with libtool (@pxref{Other
+Languages}), the source files may end in suffixes other than @samp{.c}.
+This test validates that libtool can handle suffixes for all the file
+types that it supports, and that it fails when the suffix is invalid.
+
+@item test-e.test
+This program checks that the @code{test -e} construct is @emph{never} in
+the libtool scripts. Checking for the existence of a file can only be
+done in a portable way by using @code{test -f}.
+@end table
+
+@node When Tests Fail, , Test Descriptions, Libtool Test Suite
+@comment node-name, next, previous, up
+@subsection When Tests Fail
+
+Each of the above tests are designed to produce no output when they are
+run via @kbd{make check}. The exit status of each program tells the
+Makefile whether or not the test succeeded.
+
+If a test fails, it means that there is either a programming error in
+libtool, or in the test itself.
+
+To investigate a particular test, you may run it directly, as you would
+a normal program. When the test is invoked in this way, it produces
+output which may be useful in determining what the problem is.
+
+Another way to have the test programs produce output is to set the
+@var{VERBOSE} environment variable to @samp{yes} before running them.
+For example, @kbd{make check VERBOSE=yes} runs all the tests, and has
+each of them display debugging information.

+@section Reporting Bugs
+
+If you think you have discovered a bug in libtool, you should think
+twice: the libtool maintainer is notorious for passing the buck (or
+maybe that should be ``passing the bug'').
+
+Libtool was invented to fix known deficiencies in shared library
+implementations, so, in a way, most of the bugs in libtool are actually
+bugs in other operating systems.
+
+However, the libtool maintainer would definitely be happy to add support
+for somebody else's buggy operating system. (I wish there was a way to
+do winking smiley-faces in texinfo).
+
+Genuine bugs in libtool include problems with shell script portability,
+documentation errors, and failures in the test suite (@pxref{Libtool
+Test Suite}).
+
+First, check the documentation and help screens to make sure that the
+behaviour you think is a problem is not already mentioned.
+
+Then, you should read the Emacs guide to reporting bugs (@pxref{Bugs, , The
+Emacs Manual, emacs.info, The Emacs Manual}). Some of the details
+listed there are specific to Emacs, but the priciple behind them is a
+general one.
+
+Finally, send a bug report to the libtool maintainer (@value{MAINT}),
+with any appropriate @emph{facts}, such as test suite output
+(@pxref{When Tests Fail}), all the details needed to reproduce the bug,
+and a brief description of why you think the behaviour is a bug.
