David Sommerseth 45f6e7991c Only build and run cmocka unit tests if its submodule is initialized
Commit 40cb4cfc5d added infrastructure to write unit tests using
cmocka.  This was implemented using a git submodule to fetch an
up-to-date cmocka test framework.

The issue which appeared was that 'make check' stopped working if
the cmocka submodule was not initialized and updated.  As we do not
want this to be a hard depenency, this patch makes running these
unit tests conditional.  If cmocka has not been initialized, skip
them or if it has been initialized all unit tests will be run.

 [v2 - Also check if cmake is available, as cmocka depends on that
       to be built ]

Unit Tests

This directory contains unit tests for openvpn. New features/bugfixes should be written in a test friendly way and come with corresponding tests.

Run tests

Tests are run by make check. A failed tests stops test execution. To run all tests regardless of errors call make -k check.

Add new tests to existing test suite

Test suites are organized in directories. example_test/ is an example for a test suite with two test executables. Feel free to use it as a template for new tests.

Test suites

Test suites live inside a subdirectory of $ROOT/tests/unit_tests, e.g. $ROOT/tests/unit_tests/my_feature.

Test suites are configured by a Makefile.am. Tests are executed by testdrivers. One testsuite can contain more than one testdriver.

Hints

  • Name suites & testdrivers in a way that the name of the driver says something about which component/feature is tested
  • Name the testdriver executable *_testdriver. This way it gets picked up by the default .gitignore
    • If this is not feasible: Add all output to a .gitignore* Use descriptive test names: coffee_brewing__with_no_beans__fails vs. test34
  • Testing a configurable feature? Wrap test execution with a conditional (see auth_pam for an example)
  • Add multiple test-drivers when one testdriver looks crowded with tests

New Test Suites

  1. Organize tests in folders for features.
  2. Add the new test directory to SUBDIRS in Makefile.am
  3. Edit configure.ac and add the new Makefile to AC_CONFIG_FILES
  4. Run ./configure, and enable the feature you'd like to test
  5. Make sure that make check runs your tests
  6. Check: Would a stranger be able to easily find your tests by you looking at the test output?
  7. Run ./configure, and disable the feature you'd like to test
  8. Make sure that make check does not run your tests
