collective.MockMailHost 4.0.0

Used for integration testing with Plone

Introduction

collective.MockMailHost enables integration testing of email functionality from Plone. Simply add this egg to your [test] runner section, and install this product through your Layer or TestCase.

Note

THIS IS FOR TESTING PURPOSE ONLY, do not use this product on your running Plone site. It replaces the standard MailHost with a Mock MailHost that you can poke at to check email content and recipients.

Has been tested with Plone 4 but should also work with earlier versions.

Integration

Example how to integrate collective.MockMailHost to your testing setup based on plone.app.testing. Add the package to your extras_requires section in your package’s setup.py file, so buildout will automatically download the package for you.:

setup(name='my.package',
      ...
      extras_require={
        'test': [
            'plone.app.testing',
            'collective.MockMailHost',
        ]
      },
      ...
      )

Your test layer setup could look like this example below:

from plone.app.testing import helpers, layers
from plone.testing import z2


class MyLayer(helpers.PloneSandboxLayer):
    defaultBases = (layers.PLONE_FIXTURE, )

    def setUpZope(self, app, configurationContext):
        # Load zcml
        import collective.MockMailHost
        self.loadZCML(package=collective.MockMailHost)

        # Install product and call its initialize() function
        z2.installProduct(app, 'collective.MockMailHost')

        # Note: you can skip this if my.product is not a Zope 2-style
        # product, i.e. it is not in the Products.* namespace and it
        # does not have a <five:registerPackage /> directive in its
        # configure.zcml.

    def tearDownZope(self, app):
        # Uninstall product
        z2.uninstallProduct(app, 'collective.MockMailHost')

        # Note: Again, you can skip this if my.product is not a Zope 2-
        # style product

    def setUpPloneSite(self, portal):
        helpers.quickInstallProduct(portal, 'collective.MockMailHost')

        helpers.applyProfile(portal, 'collective.MockMailHost:default')

MY_FIXTURE = MyLayer()

Using a member-posting forum

>>> from Products.CMFCore.utils import getToolByName
>>> from Products.MailHost.interfaces import IMailHost
>>> from zope.component import getUtility

>>> app = layer['app']
>>> portal = layer['portal']

Test starting conversations, replying and modifying comments in a default member-posting forum.

Let us log all exceptions, which is useful for debugging. Also, clear portlet slots, to make the test browser less confused by things like the recent portlet and the navtree.

>>> portal.error_log._ignored_exceptions = ()
>>> portal.left_slots = portal.right_slots = []
>>> workflow = portal.portal_workflow

Validate mailhost replacement

>>> portal.MailHost
<collective.MockMailHost.MockMailHost.MockMailHost object at ...>

>>> getToolByName(portal, 'MailHost')
<collective.MockMailHost.MockMailHost.MockMailHost object at ...>

>>> getUtility(IMailHost)
<collective.MockMailHost.MockMailHost.MockMailHost object at ...>

Send email

>>> to_ = "[e-mail]"
>>> from_ = "[e-mail]"
>>> msg = """
...
... Dear Sir:
...
... Thank you"""
>>> portal.MailHost.send(msg, to_, from_)
>>> len(portal.MailHost.messages)
1
>>> b'To: [e-mail]' in portal.MailHost.messages[0]
True
>>> b'From: [e-mail]' in portal.MailHost.messages[0]
True
>>> b'Dear Sir:' in portal.MailHost.messages[0]
True
>>> portal.MailHost.messages_from
['[e-mail]']
>>> portal.MailHost.messages_to
[['[e-mail]']]
>>> portal.MailHost.reset()
>>> len(portal.MailHost.messages)
0

Send an email.message.EmailMessage object with cc/bcc recipients

>>> from email.message import EmailMessage
>>> msg = EmailMessage()
>>> msg["Subject"] = "Hello"
>>> msg["From"] = "[e-mail]"
>>> msg["To"] = "[e-mail]"
>>> msg["Cc"] = "[e-mail]"
>>> msg["Bcc"] = "[e-mail]"
>>> msg.set_content("""
... This message is for you, foo, and bar.
... """)
>>> portal.MailHost.send(msg)
>>> len(portal.MailHost.messages)
1
>>> b'To: [e-mail]' in portal.MailHost.messages[0]
True
>>> b'From: [e-mail]' in portal.MailHost.messages[0]
True
>>> b'Cc: [e-mail]' in portal.MailHost.messages[0]
True
>>> b'[e-mail]' in portal.MailHost.messages[0]
False
>>> b'This message is for you, foo, and bar.' in portal.MailHost.messages[0]
True
>>> len(portal.MailHost.messages)
1
>>> portal.MailHost.messages_from
['[e-mail]']
>>> portal.MailHost.messages_to
[['[e-mail]', '[e-mail]', '[e-mail]']]
>>> portal.MailHost.reset()
>>> len(portal.MailHost.messages)
0
