-dh_auto_test is a debhelper program that is responsible for the I<test> step of
-the L<dh_auto(7)> building process. Typically, this is the point when package
-test suite is run to check if the sources were built successfully and/or
-binaries provide expected functionality. dh_auto_test will fail if test suite
-fails. However, if there's no test suite, it will exit with zero status
-without doing anything.
+B<dh_auto_test> is a debhelper program that tries to automatically run a
+package's test suite. It does so by running the appropriate command for the
+build system it detects the package uses. For example, if there's a
+Makefile and it contains a B<test> or B<check> target, then this is done by
+running B<make> (or B<MAKE>, if the environment variable is set). If the test
+suite fails, the command will exit nonzero. If there's no test suite, it
+will exit zero without doing anything.
