+Running tests
+=============
+
+The test suite makes sure that coding standards are followed and that the shell
+and fuse module work.
+
+Since the test suite will connect to a remote mediafire share, make sure that
+you have a configuration file with a username and password in place and that
+this share does not contain a file or directory called `test` as it will be
+created and removed during testing. You can also place the `config` file in
+your current directory instead of your home directory to have a separate
+configuration file for testing.
+
+To run the test suite you need additional dependencies. On Debian and
+derivatives you need:
+
+	apt-get install indent python iwyu valgrind fuse
+
+To run the tests, run:
+
+	make test
+
+The test suite is using ctest which does not produce anything on standard
+output by default. To disable this behaviour when errors happen, run:
+
+	CTEST_OUTPUT_ON_FAILURE=TRUE make test
+
+otherwise the output is in
+
+	Testing/Temporary/LastTest.log
+
+Automatically fixing discovered errors
+======================================
+
+To fix all includes:
+
+	for f in **/*.c **/*.h; do iwyu "$f" 2>&1 | fix_include; done
+
+To fix indentation (the file `.indent.pro` will be used):
+
+    indent **/*.c **/*.h
+    rm **/*\~
+
+to compile verbosely:
+
+    cmake -DCMAKE_VERBOSE_MAKEFILE=true
+
+Misc
+====
+
+When valgrind reports uninitialized memory due to aesni_cbc_encrypt, run the
+tests with:
+
+	OPENSSL_ia32cap="~0x200000000000000"
