libtool: When tests fail

1 
1 14.1.2 When tests fail
1 ----------------------
1 
1 When the tests in the old test suite are run via 'make check', output is
1 caught in per-test 'tests/TEST-NAME.log' files and summarized in the
1 'test-suite.log' file.  The exit status of each program tells the
1 'Makefile' whether or not the test succeeded.
1 
1    If a test fails, it means that there is either a programming error in
1 libtool, or in the test program itself.
1 
1    To investigate a particular test, you may run it directly, as you
1 would a normal program.  When the test is invoked in this way, it
1 produces output that may be useful in determining what the problem is.
1 
1    The new, Autotest-based test suite produces as output a file
1 'tests/testsuite.log' that contains information about failed tests.
1 
1    You can pass options to the test suite through the 'make' variable
11 'TESTSUITEFLAGS' (⇒The Autoconf Manual (autoconf)testsuite
 Invocation.).
