=head1 SYNOPSIS

B<dh_auto_test> [S<I<build system options>>] [S<I<debhelper options>>] [S<B<--> I<params>>]

=head1 DESCRIPTION

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.

This is intended to work for about 90% of packages with a test suite. If it
doesn't work, you're encouraged to skip using B<dh_auto_test> at all, and
just run the test suite manually.

=head1 OPTIONS

See L<debhelper(7)/B<BUILD SYSTEM OPTIONS>> for a list of common build
system selection and control options.

=over 4

=item B<--> I<params>

Pass I<params> to the program that is run, after the parameters that
B<dh_auto_test> usually passes.

=back

=head1 NOTES

If the B<DEB_BUILD_OPTIONS> environment variable contains B<nocheck>, no
tests will be performed.

dh_auto_test does not run the test suite when a package is being cross
compiled.
