-4. Troubleshooting
+4. Tests
+--------
+
+    The test framework can be built and run by executing "make check" in
+    the build directory. The tests are a mix of executables and POSIX
+    shell scripts (sh). All tests should pass if the default configuration
+    is used. Disabling features through the configure options may cause
+    some tests to be skipped. If any tests do not pass, see section 5.5.
+
+
+4.1. Testing in parallel
+
+    The tests can be run in parallel using the "-j" make option on systems
+    that support it. For instance, "make -j4 check" will run up to four
+    tests simultaneously.
+
+
+4.2. Cross compiling
+
+    The tests can be built without running them:
+
+        make check TESTS=
+
+    The TESTS variable is the list of tests you wish to run. Leaving it
+    empty will compile the tests without running any.
+
+    If the tests are copied to a target machine to execute, the test data
+    files in the directory tests/files must also be copied. The tests
+    search for the data files using the environment variable $srcdir,
+    expecting to find the data files under $srcdir/files/. If $srcdir
+    isn't set then it defaults to the current directory.
+
+    The shell script tests can be copied from the source directory to the
+    target machine to execute. In addition to the test files, these tests
+    will expect the following relative file paths to execute properly:
+
+        ./create_compress_files
+        ../config.h
+        ../src/xz/xz
+        ../src/xzdec/xzdec
