## ProFTPD Testsuite

The proftpd source code is accompanied by a testsuite, for testing various features and functionality. At present, the testsuite is divided into two main parts: the API-level tests, and the integration tests. The API tests are written in C, and exercise the various APIs that proftpd provides to module developers. The integration tests are currently written in Perl, and seek to check a compiled `proftpd`'s run-time behavior.

In order to run the testsuite, you must configure your proftpd build so that the testsuite is prepared. You do this by using the `--enable-tests` configure option, along with your other build options, e.g.:

      # ./configure --enable-tests ...

API Tests
The API tests use the `libcheck` library; see:

      http://check.sourceforge.net/

This library must be installed on your machine in order to run the API tests. When the `--enable-tests` configure option is used, proftpd's configure script will check for libcheck, and will fail unless the library is present. If no `libcheck` is found and you've used `--enable-tests`, you will see:

        checking for tcase_create in -lcheck... no
        configure: error: libcheck support, required for tests, not present -- aborting

Note that, if necessary, the `--with-includes` and `--with-libraries` configure options can be used to specify the locations of the `libcheck` headers and libraries.

To run the testsuite, use the `make check` target:

      # ./configure --enable-tests ...
      # make
        ...
      # make check
        ...
      ./api-tests
      Running suite(s): pool
       array
       str
       sets
       timers
       table
       var
       event
       env
       version
       feat
       netaddr
       netacl
       class
       regexp
       expr
       scoreboard
       modules
      100%: Checks: 140, Failures: 0, Errors: 0

The `make check` will also go on to run the integration tests, if the API tests all pass.

If one of the API tests fails, you will see an error message like:

      99%: Checks: 140, Failures: 1, Errors: 0
      api/env.c:53:F:base:env_get_test:0: Failed to handle null arguments
      -------------------------------------------------
       FAILED 1 test

       Please send email to:

         proftp-devel@lists.sourceforge.net

       containing the `api-tests.log' file (in the tests/ directory)
       and the output from running `proftpd -V'
      -------------------------------------------------

Please do follow those instructions; you will be helping in proftpd development!

Integration Tests
The current integration tests are written in Perl, and rely on the `Test-Unit` Perl package. Specifically, you must use `Test-Unit-0.14`, not `Test-Unit-0.25`. Not sure which version of `Test-Unit` you have, if at all? Run the following command:

      # perl -MTest::Unit -e 'print $Test::Unit::VERSION, "\n";'
      0.14

To run the integration tests manually, use the `tests.pl` script:

      # cd tests/
      # perl tests.pl
      t/logins.....................ok
      t/commands/user..............ok
      t/commands/pass..............ok
      t/commands/pwd...............ok
      t/commands/cwd...............ok
      t/commands/cdup..............ok
      t/commands/syst..............ok
      t/commands/type..............ok
      t/commands/mkd...............ok
      t/commands/rmd...............ok
      t/commands/dele..............ok
      t/commands/mdtm..............ok
      t/commands/size..............ok
      t/commands/mode..............ok
      t/commands/stru..............ok
      t/commands/allo..............ok
      t/commands/noop..............ok
      t/commands/feat..............ok
      t/commands/help..............ok
      t/commands/quit..............ok
      t/commands/rnfr..............ok
      t/commands/rnto..............ok
      t/commands/rest..............ok
      t/commands/pasv..............ok
      t/commands/epsv..............ok
      t/commands/port..............ok
      t/commands/eprt..............ok
      t/commands/nlst..............ok
      t/commands/list..............ok
      t/commands/retr..............ok
      t/commands/stor..............ok
      t/commands/appe..............ok
      t/config/displayconnect......ok
      t/config/displaylogin........ok
      t/config/maxloginattempts....ok
      t/config/serverident.........ok
      All tests successful.
      Files=37, Tests=141, 160 wallclock secs ( 4.33 cusr +  4.74 csys =  9.07 CPU)

Some of the integration require root privileges in order to perform the test properly, e.g. for `<Anonymous>`/`DefaultRoot` logins, etc. If you do not run `make check' as root, those tests which require root privileges are automatically skipped. Thus for doing a full regression, run the integration tests as the root user.

Adding New Tests
The following information is for those who are interested in adding new tests, updating existing tests, or otherwise helping with the testsuite development.

The API tests driver, `api-tests`, honors the `PR_TEST_SUITE` environment variable. This is useful for running just the test cases associated with a particular suite, such as env or pool. Only one suite can be specified using the `PR_TEST_SUITE` environment variable:

      # make check
      # cd tests/
      # PR_TEST_SUITE=pool ./api-tests
      Running suite(s): pool
      100%: Checks: 5, Failures: 0, Errors: 0

This way, when you are adding to an existing test case or adding a new test case to an existing suite, you need not run the entire API testsuite in order to run your changes.
