testplan: A Python repository from rnemes

a multi-testing framework

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

Testplan is a Python 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.

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:

$ 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.

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:

$ 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:

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