- <h2>The build tests</h2>
+ <a name="layout"></a>
+ <h3>Testsuite development</h3>
- <p>
- With our build tests, we check if deal.II can be compiled on
- different systems and with different compilers as well as
- different configuration options. Results are collected in a
- database and can be accessed <a
- href="http://www.dealii.org/testsuite.html">online</a>.<p>
+ <p class="todo"> Here, some text is missing</p>
- <p>Running the build test suite is simple and we encourage deal.II
- users with configurations not found on the <a
- href="http://www.dealii.org/testsuite.html">test suite page</a> to
- participate. Assuming you checked out deal.II into the directory
- <code>dealtest</code>, running it is as simple as:
+
+
+ <a name="layoutgeneral"></a>
+ <h3>General layout</h3>
+
+ <p>
+ A test usually consists of a source file and an output file for
+ comparison (under the testsuite directory <code>tests</code>):
<pre>
- cd dealtest
- svn update
- ./contrib/utilities/build_test
- mail build-tests@dealii.org < *.log
- ( rm *.log )
+ category/test.cc
+ category/test[...].output
</pre>
+ <code>test.cc</code> must be a regular executable (i.e. having an
+ <code>int main()</code> routine). It will be compiled, linked and
+ run. The executable should not output anything to <code>cout</code>
+ (at least under normal circumstances, i.e. no error condition),
+ instead the executable should output to a file <code>output</code>
+ under the current working directory.
</p>
+ <p>
+ In detail, for a regular test the following 3 stages will be run:
+ <ul>
+ <li>
+ <code>BUILD</code>: The build stage generates an executable in
+ <code>BUILD_DIR/tests/<category>/<test></code>.
+ </li>
+ <li>
+ <code>RUN</code>: The run stages invokes the executable that
+ generates an output file
+ <code>BUILD_DIR/tests/<category>/<test>/output</code>.
+ If the run fails (e.g. because the program aborts with an error
+ code) the file <code>output</code> is renamed to
+ <code>failing_output</code>.
+ </li>
+ <li>
+ <code>DIFF</code>: As a last stage the generated output file will
+ be compared to
+ <code>SOURCE_DIR/tests/<category>/<test>[...].output</code>.
+ and stored in
+ <code>BUILD_DIR/tests/<category>/<test>/diff</code>.
+ If the diff fails the file <code>diff</code> is renamed to
+ <code>failing_diff</code>.
+ </li>
+ </ul>
<p>
- The <code>build_test</code> script supports the following options:
- <pre>
+ </p>
- SOURCEDIR - the source directory to use (otherwise the current directory is used)
- CONFIGFILE - A cmake configuration file for the build test
- LOGDIR - directory for the log file
- LOGFILE - the logfile to use, defaults to
- $LOGDIR/$BRANCH.$CONFIGFILE.<unix time>.log
+ <a name="layoutcomparisonfile"></a>
+ <h3>Comparison file</h3>
- CMAKE - the cmake executable to use
- SVN - svn info command to use, defaults to
- svn info $(SOURCEDIR)
- TMPDIR - defaults to "/tmp"
- CLEAN_TMPDIR - defaults to "true"
- RUN_EXAMPLES - defaults to "true"
- </pre>
- An example configuration file can be found <a
- href="../users/Config.sample">here</a>. Options can be passed either via
- environment
+ <p>
+ The full file signature for a comparison file is
<pre>
- export CONFIGFILE=MyConfiguration.conf
- ./contrib/utilities/build_test
+ category/test.[with_<feature>=<on|off>.]*[mpirun=<x>.][<debug|release>.]output
</pre>
- or directly on the command line:
+ which is explained in detail below.
+ </p>
+
+ <h4>Restrict tests for build configurations</h4>
+ <p>
+ Normally, a test will be set up for debug and release configuration
+ (if deal.II was configured with combined <code>DebugRelease</code>
+ build type) or for the available build configuration (if deal.II was
+ configured either with <code>Debug</code> or with
+ <code>Release</code> only build type).
+ If a specific test can only be run in debug or release configurations but
+ not in both it is possible to restrict the setup by prepeding
+ <code>.debug</code> or <code>.release</code> directly before
+ <code>.output</code>, e.g.:
<pre>
- ./contrib/utilities/build_test CONFIGFILE=myConfiguration.conf
+ category/test.debug.output
</pre>
+ This way, test will only be set up to build and run against the debug
+ library.
</p>
<p>
- A status indicator should appear on the build test website after some
- time (results are collected and processed by a program that is run
- periodically, but not immediately after a mail has been received).
- </p>
+ <b>Note:</b> It is possible to provide both configuration types at the
+ same time:
+ <pre>
- <h3>Dedicated build tests</h3>
+ category/test.debug.output
+ category/test.release.output
+ </pre>
+ This will set up two seperate tests, one for the debug configuration that
+ will be tested against test.debug.output, and similarly one for release.
+ <h4>Restrict tests for feature configurations</h4>
<p>
- There is a detailed example for dedicated build tests on the <a
- href="https://code.google.com/p/dealii/wiki/BuildTests">wiki</a>.
- </p>
-
-
+ In a similar vain as for build configurations, it is possible to restrict
+ tests to specific feature configurations, e.g.:
+ <pre>
- <a name="regression_tests"></a>
- <h2>The regression tests</h2>
+ category/test.with_umfpack=on.output, or
+ category/test.with_zlib=off.output
+ </pre>
+ These tests will only be set up if the specified feature was configured
+ accordingly.
+ </p>
<p>
- deal.II has a testsuite that, at the time this article is written
- (mid-2013), has some 2,900 small programs (growing by roughly one per
- day) that we run every time we make a change to make sure that no
- existing functionality is broken. The expected output is also stored in
- our subversion archive, and when you run a test you are notified if a

- target="body">a webpage showing the status of our regression tests</a>.
+ <b>Note:</b> It is possible to provide different output files for disabled/enabled
+ features, e.g.
+ <pre>
+
+ category/test.with_64bit_indices=on.output
+ category/test.with_64bit_indices=off.output
+ </pre>
</p>
+ <p>
+ <b>Note:</b> It is possible to declare multiple constraints subsequently, e.g.
+ <pre>
+ category/test.with_umfpack=on.with_zlib=on.output
+ </pre>
+ </p>
<p>
- If you develop parts of deal.II, want to add something, or fix a bug
- in it, we encourage you to use our testsuite. This page documents
- some aspects of it.
+ <b>Note:</b> Quite a number of test categories are already guarded so
+ that the contained tests will only be set up if the feature is
+ enabled. In this case a feature constraint in the output file name is
+ redundant and should be avoided. (Folders with guards are

+ <code>trilinos</code>, <code>umfpack</code>, <code>gla</code>,

+ <h4>Run mpi tests with mpirun</h4>
+ <p>
+ If a test should be run with mpirun in parallel, specify the number x of
+ simultaneous processes in the following way:
+ <pre>
-
- <h3>Running it</h3>
-
-
+ category/test.mpirun=x.output

+ <p>
+ <b>Note:</b> It is possible to provide multiple output files for different mpirun
+ values.

<h3>Adding new tests</h3>
<p>
<h4>The testcase</h4>
<p>
For the testcase, we usually start from a template like this:
- <pre>
-
+ <pre class="cmake"> <!-- TODO -->
// ---------------------------------------------------------------------
// $Id$
//
int main ()
{
- std::ofstream logfile("my_new_test/output");
+ std::ofstream logfile("output");
deallog.attach(logfile);
deallog.depth_console(0);
}
</pre>
- <p>You open an output file in a directory with the same
- name as your test, and then write
- all output you generate to it,
- through the <code>deallog</code> stream. The <code>deallog</code>
- stream works like any
- other <code>std::ostream</code> except that it does a few more
- things behind the scenes that are helpful in this context. In
- above case, we only write a zero to the output
- file. Most tests actually write computed data to the output file
- to make sure that whatever we compute is what we got when the
- test was first written.

<p>
directories for PETSc and Trilinos wrapper functionality.
</p>
- <h4>A directory with the same name as the test</h4>
-
- <p> You have to create a subdirectory
- with the same name as your test to hold the output from the test.
-
- <p> One convenient way to create this subdirectory with the correct
- properties is to use svn copy.
- <pre>
-
- svn copy existing_test_directory my_new_test
- </pre>
+ <h4>An expected output</h4>
<p>
- Once you have done this, you can try to run
- <pre>
-
- make my_new_test/output
- </pre>
- This should compile, link, and run your test. Running your test
- should generate the desired output file.
- </p>
-
+ In order to run your new test, copy it to an appropriate category and
+ create an empty comparison file for it:
+ <pre>
+ category/my_new_test.cc
+ category/my_new_test.output
+ </pre>
+ Now, rerun
+ <pre>
- <h4>An expected output</h4>
+ $ make setup_test
+ </pre>
+ so that your new test is picked up. After that it is possible to
+ invoke it with
+ <pre>
- <p>
- If you run your new test executable, you will get an output file
- <code>mytestname/output</code> that should be used to compare all future
- runs with. If the test
- is relatively simple, it is often a good idea to look at the
- output and make sure that the output is actually what you had
- expected. However, if you do complex operations, this may
- sometimes be impossible, and in this case we are quite happy with
- any reasonable output file just to make sure that future
- invokations of the test yield the same results.
+ $ ctest -V -R "category/my_new_test"
+ </pre>
</p>
<p>
- The next step is to copy this output file to the place where the
- scripts can find it when they compare with newer runs. For this, you first
- have to understand how correct results are verified. It works in the
- following way: for each test, we have subdirectories
- <code>testname/cmp</code> where we store the expected results in a file
- <code>testname/cmp/generic</code>. If you create a new test, you should
- therefore create this directory, and copy the output of your program,
- <code>testname/output</code> to <code>testname/cmp/generic</code>.
+ If you run your new test executable this way, the test should compile
+ and run successfully but fail in the diff stage (due to the empty
+ comparison file). You will get an output file
+ <code>BUILD_DIR/category/my_new_test/output</code> that should be
+ used to compare all future runs with. If the test is relatively
+ simple, it is often a good idea to look at the output and make sure
+ that the output is actually what you had expected. However, if you do
+ complex operations, this may sometimes be impossible, and in this
+ case we are quite happy with any reasonable output file just to make
+ sure that future invokations of the test yield the same results.
</p>
<p>
- Why <code>generic</code>? The reason is that sometimes test results
- differ slightly from platform to platform, for example because numerical
- roundoff is different due to different floating point implementations on
- different CPUs. What this means is that sometimes a single stored output is
- not enough to verify that a test functioned properly: if you happen to be
- on a platform different from the one on which the generic output was
- created, your test will always fail even though it produces almost exactly
- the same output.
+ The next step is to copy and rename this output file to the source
+ directory and replace the original comparison file with it:
+ <pre>
+
+ category/my_new_test.output
+ </pre>
+ At this point running the test again should be successful:
+ <pre>
+
+ $ ctest -V -R "category/my_new_test"
+ </pre>
</p>
+ <h4>Checking in</h4>
+
<p>
- To avoid this, what the makefiles do is to first check whether an output
- file is stored for this test and your particular configuration (platform
- and compiler). If this isn't the case, it goes through a hierarchy of files
- with related configurations, and only if none of them does it take the
- generic output file. It then compares the output of your test run with the
- first file it found in this process. To make things a bit clearer, if you
- are, for example, on a <code>i686-pc-linux-gnu</code> box and use
- <code>gcc4.0</code> as your compiler, then the following files will be
- sought (in this order):
- <pre>
+ Tests are a way to make sure everything keeps working. If they
+ aren't automated, they are no good. We are therefore very
+ interested in getting new tests. If you have subversion write access
+ already, you can add the new test and the expected output
+ file:
+ <pre>
-testname/cmp/i686-pc-linux-gnu+gcc4.0
-testname/cmp/i686-pc-linux-gnu+gcc3.4
-testname/cmp/i686-pc-linux-gnu+gcc3.3
-testname/cmp/generic
- </pre>
- (This list is generated by the <code>tests/hierarchy.pl</code> script.)
- Your output will then be compared with the first one that is actually
- found. The virtue of this is that we don't have to store the output files
- from all possible platforms (this would amount to gigabytes of data), but
- that we only have store an output file for gcc4.0 if it differs from that
- of gcc3.4, and for gcc3.4 if it differs from gcc3.3. If all of them are the
- same, we would only have the generic output file.
+ svn add category/my_new_test.cc
+ svn add category/my_new_test.output
+ svn commit -m "New test"
+ </pre>
+ If you don't have subversion write access, talk to us in the
+ discussion group; writing testcases is a worthy and laudable task,
+ and we would like to encourage it by giving people the opportunity to
+ contribute!
</p>
- <p>
- Most of the time, you will be able to generate output files only
- for your own platform and compiler, and that's alright: someone
- else will create the output files for other platforms
- eventually. You only have to copy your output file to
- <code>testname/cmp/generic</code>.
