a multi-testing framework

..because unit tests can only go so far..

Testplan is a Python <http://python.org>_ package that can start a local live environment, setup mocks, connections to services and run tests against these. It provides:

• MultiTest a feature extensive functional testing system with a rich set of assertions and report rendering logic.
• Built-in inheritable drivers to create a local live environment.
• Configurable, diverse and expandable test execution mechanism including parallel execution capability.
• Test tagging for flexible filtering and selective execution as well as generation of multiple reports (for each tag combination).
• Integration with other unit testing frameworks (like GTest).
• Rich, unified reports (json/PDF/XML) and soon (HTML/UI).

Basic example

This is how a very basic Testplan application looks like.

.. code-block:: python

import sys

from testplan import test_plan
from testplan.testing.multitest import MultiTest, testcase, testsuite

def multiply(numA, numB):
    return numA * numB


@testsuite
class BasicSuite(object):

    @testcase
    def basic_multiply(self, env, result):
        result.equal(multiply(2, 3), 6, description='Passing assertion')
        result.equal(multiply(2, 2), 5, description='Failing assertion')


@test_plan(name='Multiply')
def main(plan):
    test = MultiTest(name='MultiplyTest',
                     suites=[BasicSuite()])
    plan.add(test)


if __name__ == '__main__':
  sys.exit(not main())

Example execution:

.. code-block:: bash

$ python ./test_plan.py -v
        Passing assertion - Pass
          6 == 6
        Failing assertion - Fail
          File: .../test_plan.py
          Line: 18
          4 == 5
      [basic_multiply] -> Fail
    [BasicSuite] -> Fail
  [MultiplyTest] -> Fail
[Multiply] -> Fail

System integration testing example

Testing a server and a client communication.

.. code-block:: python

import sys

from testplan import test_plan
from testplan.testing.multitest import MultiTest, testsuite, testcase
from testplan.testing.multitest.driver.tcp import TCPServer, TCPClient
from testplan.common.utils.context import context


@testsuite
class TCPTestsuite(object):
    """Testsuite for server client connection testcases."""

    def setup(self, env):
        env.server.accept_connection()

    @testcase
    def send_and_receive_msg(self, env, result):
        """Basic send and receive hello message testcase."""
        msg = env.client.cfg.name
        result.log('Client is sending his name: {}'.format(msg))
        bytes_sent = env.client.send_text(msg)

        received = env.server.receive_text(size=bytes_sent)
        result.equal(received, msg, 'Server received client name')

        response = 'Hello {}'.format(received)
        result.log('Server is responding: {}'.format(response))
        bytes_sent = env.server.send_text(response)

        received = env.client.receive_text(size=bytes_sent)
        result.equal(received, response, 'Client received response')


@test_plan(name='TCPConnections')
def main(plan):
    test = MultiTest(name='TCPConnectionsTest',
                     suites=[TCPTestsuite()],
                     environment=[
                         TCPServer(name='server'),
                         TCPClient(name='client',
                                   host=context('server', '{{host}}'),
                                   port=context('server', '{{port}}'))])
    plan.add(test)


if __name__ == '__main__':
    sys.exit(not main())

Example execution:

.. code-block:: bash

$ python ./test_plan.py -v
        Client is sending: client
        Server received - Pass
          client == client
        Server is responding: Hello client
        Client received - Pass
          Hello client == Hello client
      [send_and_receive_msg] -> Pass
    [TCPTestsuite] -> Pass
  [TCPConnectionsTest] -> Pass
[TCPConnections] -> Pass

A persistent and human readable test evidence PDF report:

.. code-block:: bash

$ python ./test_plan.py --pdf report.pdf
  [TCPConnectionsTest] -> Pass
[TCPConnections] -> Pass
PDF generated at report.pdf
