+ The directory <span class="emphasis"><em>libsrcdir/testsuite</em></span> contains the
+ individual test cases organized in sub-directories corresponding to
+ chapters of the C++ standard (detailed below), the dejagnu test
+ harness support files, and sources to various testsuite utilities
+ that are packaged in a separate testing library.
+</p><p>
+ All test cases for functionality required by the runtime components
+ of the C++ standard (ISO 14882) are files within the following
+ directories.
+</p><pre class="programlisting">
+17_intro
+18_support
+19_diagnostics
+20_util
+21_strings
+22_locale
+23_containers
+25_algorithms
+26_numerics
+27_io
+ </pre><p>
+ In addition, the following directories include test files:
+ </p><pre class="programlisting">
+tr1 Tests for components as described by the Technical Report on Standard Library Extensions (TR1).
+backward Tests for backwards compatibility and deprecated features.
+demangle Tests for __cxa_demangle, the IA 64 C++ ABI demangler
+ext Tests for extensions.
+performance Tests for performance analysis, and performance regressions.
+thread Tests for threads.
+ </pre><p>
+ Some directories don't have test files, but instead contain
+ auxiliary information (<a class="ulink" href="#internals" target="_top">more information</a>):
+ </p><pre class="programlisting">
+config Files for the dejagnu test harness.
+lib Files for the dejagnu test harness.
+libstdc++* Files for the dejagnu test harness.
+data Sample text files for testing input and output.
+util Files for libtestc++, utilities and testing routines.
+ </pre><p>
+ Within a directory that includes test files, there may be
+ additional subdirectories, or files. Originally, test cases
+ were appended to one file that represented a particular section
+ of the chapter under test, and was named accordingly. For
+ instance, to test items related to <code class="code"> 21.3.6.1 -
+ basic_string::find [lib.string::find]</code> in the standard,
+ the following was used:
+ </p><pre class="programlisting">
+21_strings/find.cc
+ </pre><p>
+ However, that practice soon became a liability as the test cases
+ became huge and unwieldy, and testing new or extended
+ functionality (like wide characters or named locales) became
+ frustrating, leading to aggressive pruning of test cases on some
+ platforms that covered up implementation errors. Now, the test
+ suite has a policy of one file, one test case, which solves the
+ above issues and gives finer grained results and more manageable
+ error debugging. As an example, the test case quoted above
+ becomes:
+ </p><pre class="programlisting">
+21_strings/basic_string/find/char/1.cc
+21_strings/basic_string/find/char/2.cc
+21_strings/basic_string/find/char/3.cc
+21_strings/basic_string/find/wchar_t/1.cc
+21_strings/basic_string/find/wchar_t/2.cc
+21_strings/basic_string/find/wchar_t/3.cc
+ </pre><p>
+ All new tests should be written with the policy of one test
+ case, one file in mind.

+ In addition, there are some special names and suffixes that are

+ tests.
+ </p><div class="itemizedlist"><ul type="disc"><li><p>
+ <span class="emphasis"><em>_xin.cc</em></span>
+ </p><p>
+ This test case expects some kind of interactive input in order

+ </p></li><li><p>
+ <span class="emphasis"><em>char</em></span>

+ </p></li><li><p>
+ <span class="emphasis"><em>wchar_t</em></span>
+ </p><p>
+ This can either be a directory name or part of a longer file

+ </p><p>
+ These commands are functionally equivalent and will create a

+ There are several options for running tests, including testing
+ the regression tests, testing a subset of the regression tests,
+ testing the performance tests, testing just compilation, testing
+ installed tools, etc. In addition, there is a special rule for
+ checking the exported symbols of the shared library.
+ </p><p>
+ To debug the dejagnu test harness during runs, try invoking with a
+ specific argument to the variable RUNTESTFLAGS, as below.
+ </p><pre class="programlisting">
+make check-target-libstdc++-v3 RUNTESTFLAGS="-v"
+</pre><p>
+ or
+ </p><pre class="programlisting">
+make check-target-libstdc++-v3 RUNTESTFLAGS="-v -v"
+</pre><p>
+ To run a subset of the library tests, you will need to generate
+ the <span class="emphasis"><em>testsuite_files</em></span> file by running
+ <span class="command"><strong>make testsuite_files</strong></span> in the
+ <span class="emphasis"><em>libbuilddir/testsuite</em></span> directory, described
+ below. Edit the file to remove the tests you don't want and
+ then run the testsuite as normal.
+ </p><p>
+ There are two ways to run on a simulator: set up DEJAGNU to point to a
+ specially crafted site.exp, or pass down --target_board flags.
+ </p><p>
+ Example flags to pass down for various embedded builds are as follows:
+ </p><pre class="programlisting">
+ --target=powerpc-eabism (libgloss/sim)
+make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=powerpc-sim"
+
+--target=calmrisc32 (libgloss/sid)
+make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=calmrisc32-sid"
+
+--target=xscale-elf (newlib/sim)
+make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=arm-sim"
+</pre><p>
+ Also, here is an example of how to run the libstdc++ testsuite
+ for a multilibed build directory with different ABI settings:
+ </p><pre class="programlisting">
+make check-target-libstdc++-v3 RUNTESTFLAGS='--target_board \"unix{-mabi=32,,-mabi=64}\"'
+</pre><p>
+ You can run the tests with a compiler and library that have
+ already been installed. Make sure that the compiler (e.g.,
+ <code class="code">g++</code>) is in your <code class="code">PATH</code>. If you are
+ using shared libraries, then you must also ensure that the
+ directory containing the shared version of libstdc++ is in your
+ <code class="code">LD_LIBRARY_PATH</code>, or equivalent. If your GCC source
+ tree is at <code class="code">/path/to/gcc</code>, then you can run the tests
+ as follows:
+ </p><pre class="programlisting">
+runtest --tool libstdc++ --srcdir=/path/to/gcc/libstdc++-v3/testsuite
+</pre><p>
+ The testsuite will create a number of files in the directory in
+ which you run this command,. Some of those files might use the
+ same name as files created by other testsuites (like the ones
+ for GCC and G++), so you should not try to run all the
+ testsuites in parallel from the same directory.
+ </p><p>
+ In addition, there are some testing options that are mostly of
+ interest to library maintainers and system integrators. As such,
+ these tests may not work on all cpu and host combinations, and
+ may need to be executed in the
+ <span class="emphasis"><em>libbuilddir/testsuite</em></span> directory. These
+ options include, but are not necessarily limited to, the
+ following:
+ </p><pre class="programlisting">
+ make testsuite_files
+ </pre><p>
+ Five files are generated that determine what test files
+ are run. These files are:
+ </p><div class="itemizedlist"><ul type="disc"><li><p>
+ <span class="emphasis"><em>testsuite_files</em></span>
+ </p><p>
+ This is a list of all the test cases that will be run. Each

+ </p></li><li><p>
+ <span class="emphasis"><em>testsuite_files_interactive</em></span>
+ </p><p>

+ </p></li></ul></div><pre class="programlisting">
+ make check-abi

+ </p><pre class="programlisting">

+ To run the libstdc++ test suite under the <a class="link" href="debug_mode.html" title="Chapter 30. Debug Mode">debug mode</a>, edit
+ <code class="filename">libstdc++-v3/scripts/testsuite_flags</code> to add the

+ option. Additionally, add the
+ <code class="constant">-D_GLIBCXX_DEBUG_PEDANTIC</code> flag to turn on
+ pedantic checking. The libstdc++ test suite should produce
+ precisely the same results under debug mode that it does under
+ release mode: any deviation indicates an error in either the
+ library or the test suite.
+ </p><p>
+ The <a class="link" href="parallel_mode.html" title="Chapter 31. Parallel Mode">parallel
+ mode</a> can be tested in much the same manner, substituting
+ <code class="constant">-D_GLIBCXX_PARALLEL</code> for
+ <code class="constant">-D_GLIBCXX_DEBUG</code> in the previous paragraph.
+ </p><p>
+ Or, just run the testsuites with <code class="constant">CXXFLAGS</code>
+ set to <code class="constant">-D_GLIBCXX_DEBUG</code> or
+ <code class="constant">-D_GLIBCXX_PARALLEL</code>.

+ The first step in making a new test case is to choose the correct
+ directory and file name, given the organization as previously
+ described.
+ </p><p>
+ All files are copyright the FSF, and GPL'd: this is very
+ important. The first copyright year should correspond to the date
+ the file was checked in to SVN.
+ </p><p>
+ As per the dejagnu instructions, always return 0 from main to
+ indicate success.
+ </p><p>
+ A bunch of utility functions and classes have already been
+ abstracted out into the testsuite utility library, <code class="code">
+ libtestc++</code>. To use this functionality, just include the
+ appropriate header file: the library or specific object files will
+ automatically be linked in as part of the testsuite run.
+ </p><p>
+ For a test that needs to take advantage of the dejagnu test
+ harness, what follows below is a list of special keyword that
+ harness uses. Basically, a test case contains dg-keywords (see
+ dg.exp) indicating what to do and what kinds of behavior are to be
+ expected. New test cases should be written with the new style
+ DejaGnu framework in mind.
+ </p><p>
+ To ease transition, here is the list of dg-keyword documentation
+ lifted from dg.exp.
+ </p><pre class="programlisting">
+# The currently supported options are:
+#
+# dg-prms-id N
+# set prms_id to N
+#
+# dg-options "options ..." [{ target selector }]
+# specify special options to pass to the tool (eg: compiler)
+#
+# dg-do do-what-keyword [{ target/xfail selector }]
+# `do-what-keyword' is tool specific and is passed unchanged to
+# ${tool}-dg-test. An example is gcc where `keyword' can be any of:
+# preprocess|compile|assemble|link|run
+# and will do one of: produce a .i, produce a .s, produce a .o,
+# produce an a.out, or produce an a.out and run it (the default is
+# compile).
+#
+# dg-error regexp comment [{ target/xfail selector } [{.|0|linenum}]]
+# indicate an error message <regexp> is expected on this line
+# (the test fails if it doesn't occur)
+# Linenum=0 for general tool messages (eg: -V arg missing).
+# "." means the current line.
+#
+# dg-warning regexp comment [{ target/xfail selector } [{.|0|linenum}]]
+# indicate a warning message <regexp> is expected on this line
+# (the test fails if it doesn't occur)
+#
+# dg-bogus regexp comment [{ target/xfail selector } [{.|0|linenum}]]
+# indicate a bogus error message <regexp> use to occur here
+# (the test fails if it does occur)
+#
+# dg-build regexp comment [{ target/xfail selector }]
+# indicate the build use to fail for some reason
+# (errors covered here include bad assembler generated, tool crashes,
+# and link failures)
+# (the test fails if it does occur)
+#
+# dg-excess-errors comment [{ target/xfail selector }]
+# indicate excess errors are expected (any line)
+# (this should only be used sparingly and temporarily)
+#
+# dg-output regexp [{ target selector }]
+# indicate the expected output of the program is <regexp>
+# (there may be multiple occurrences of this, they are concatenated)
+#
+# dg-final { tcl code }
+# add some tcl code to be run at the end
+# (there may be multiple occurrences of this, they are concatenated)
+# (unbalanced braces must be \-escaped)
+#
+# "{ target selector }" is a list of expressions that determine whether the
+# test succeeds or fails for a particular target, or in some cases whether the
+# option applies for a particular target. If the case of `dg-do' it specifies
+# whether the test case is even attempted on the specified target.
+#
+# The target selector is always optional. The format is one of:
+#
+# { xfail *-*-* ... } - the test is expected to fail for the given targets
+# { target *-*-* ... } - the option only applies to the given targets
+#
+# At least one target must be specified, use *-*-* for "all targets".
+# At present it is not possible to specify both `xfail' and `target'.
+# "native" may be used in place of "*-*-*".
+
+Example 1: Testing compilation only
+// { dg-do compile }
+
+Example 2: Testing for expected warnings on line 36, which all targets fail
+// { dg-warning "string literals" "" { xfail *-*-* } 36
+
+Example 3: Testing for expected warnings on line 36
+// { dg-warning "string literals" "" { target *-*-* } 36
+
+Example 4: Testing for compilation errors on line 41
+// { dg-do compile }
+// { dg-error "no match for" "" { target *-*-* } 41 }
+
+Example 5: Testing with special command line settings, or without the
+use of pre-compiled headers, in particular the stdc++.h.gch file. Any
+options here will override the DEFAULT_CXXFLAGS and PCH_CXXFLAGS set
+up in the normal.exp file.
+// { dg-options "-O0" { target *-*-* } }

+our own. Callbacks must be prefixed with the name of the tool. To easily
+distinguish the others, by convention our own routines are named "v3-*".
+</p><p>The next key point when working with dejagnu is "test files". Any

+(We have only one.) In those directories, any <code class="code">.exp</code> file is
+considered a test file, and will be run in turn. Our main test file is called
+<code class="code">normal.exp</code>; it runs all the tests in testsuite_files using the
+callbacks loaded from the support library.
+</p><p>The <code class="code">config</code> directory is searched for any particular "target
