behaving
========

*behaving* is a web application testing framework for
Behavior-Driven-Development, based on
[behave](http://pypi.python.org/pypi/behave) and
[splinter](https://github.com/cobrateam/splinter).

*behave* is written in Python and is similar to
[Cucumber](http://cucumber.io/).
*behaving* adds the step-libraries for multi-user web/email/sms/gcm
interactions, and provides the Python *behaving* namespace so that
independent step-libraries can work together.

Please refer to *behave*'s excellent
[documentation](http://behave.readthedocs.io/en/latest/) for a guide on
how to use it, how to write your custom steps and make it possible to
extend *behaving*.

Hello world
-----------

Starting to use *behaving* is pretty easy. Inside some python module,
add your *features* consisting each of one or more scenarios. These
features are Gherkin language files with an extension of `.feature`. In
the same directory you should have a steps module which imports the
*behaving* steps as well as your own custom steps (more on that later in
the setup\_ section) . Here's a basic example:

    Feature: Text presence

        Background:
            Given a browser

        Scenario: Search for BDD
            When I visit "http://www.wikipedia.org/"
            And I fill in "search" with "BDD"
            And I press "go"
            Then I should see "Behavior-driven development" within 5 seconds

Email, SMS & GCM (Google Cloud Messaging)
-----------------------------------------

While the web is the focus of *behaving*, it also includes simple mocks
for a mail, SMS and a GCM server. These come with a small collection of
steps allowing you to do things like:

    Feature: Email & SMS

        Scenario: Click link in an email
            Given a browser
            When I send an email to "foo@bar.com" with subject "Crypho" and body "Try out our product at http://crypho.com"
            And I click the link in the email I received at "foo@bar.com"
            Then the browser's URL should be "http://crypho.com/"

        Scenario: Receive SMS with body
            When I send an sms to "+4745690001" with body "Hello world"
            Then I should receive an sms at "+4745690001" containing "world"

        Scenario: Receive GCM Notification
            When I send a gcm message "{"to":"deviceID", "data": {"message": "Foo Bar", "badge": 6}}"
            Then I should receive a gcm notification at "deviceID" containing "{'data': {'message': 'Foo Bar'}}"

Typically, it will be your web application that sends
email/sms/notifications and testing it comes down to configuring the
application to send email/sms/notifications to the mock servers.

Personas & state
----------------

A lot of web apps today rely on multi-user interactions. To help you
with those interactions, *behaving* uses the notion of *personas*. A
persona within a test runs in its own instance of a browser and you can
have more than one persona (and its browser instance) running
concurrently. You switch among personas by calling

    Given "PersonaName" as the persona

Personas are also typically implemented as simple dictionaries allowing
them to carry state, save and reuse variables inside a scenario. When a
persona is first invoked it is created as an empty dictionary. You can
predefine personas though with set values.

Let's take the familiar LOTR characters as our test users. On setting up
the test environment (details later in the setup\_ section), we set up
the characters basic variables we might be needing in the tests as such:

    PERSONAS = {
        'Frodo': dict(
                fullname=u'Frodo Baggins',
                email=u'frodo@shire.com',
                password=u'frodopass',
                mobile='+4745690001',
                address: {
                    street: "The Shire",
                    zip: "4321"
                }

            ),

        'Gandalf': dict(
                fullname=u'Gandalf the Grey',
                email=u'gandalf@wizardry.com',
                password=u'gandalfpass',
                mobile='+4745690004',
                address: {
                    street: "Rivendell street 1",
                    zip: "1234"
                }
            ),
        ...
    }

    def before_scenario(context, scenario):
        ...
        context.personas = PERSONAS

Within a test and given a persona, you can now use `$var_name` to access
a variable of a persona. You can also set new variables on personas. So
the following,

    Given "Gandalf" as the persona
    When I fill in "name" with "$fullname"
    And I fill in "street" with "$address.street"
    And I set "title" to the text of "document-title"
    And I fill in "delete" with "$title"
    And I set "address.country" to the text of "country"
    And I set "postaddress" to:
    """
    $fullname
    $address.street, $address.zip, $address.country
    """

would fill in the field with id `name` with `Gandalf the Grey`, `street`
with `Rivendell street 1` set the variable `title` to the text of the
element with id `document-title` and reuse the variable `title` to fill
in the field with id `delete`. It would also store the value of the
field with id "country" in address[`country`]. The `$var_name` pattern
is also usable in the text received by steps that expect a body of text,
which means that the `postaddress` persona variable will contain
Gandalf's complete snail-mail postage address nicely formatted on
multiple lines.

Hello Persona example
---------------------

Let us assume the following (coming from a real example) scenario.
[Crypho](https://crypho.com), is an online messaging/sharing site that
provides users with end-to-end encrypted real-time communications.
*behaving* was written to help test Crypho.

In Crypho, teams collaborate in *spaces*. To invite somebody in a
*space* the invitee has to share a token with an invitor, so both can
verify each other's identity.

    Feature: Frodo invites Gandalf to The Shire space

        Given state "the-shire"

        Scenario: Frodo invites Gandalf to The Shire

            Given "Gandalf" as the persona
            When I log in

Before the scenarios start, the custom step `Given state "the-shire"`
executes. This preloads the db with data, sets up the server etc. Then
the scenario executes:

First Gandalf logs in. The step `Given "Gandalf" as the persona`, fires
up a browser that belongs to the persona Gandalf. The following step,
`When I log in` is a custom step defined as follows:

    @when('I log in')
    def log_in(context):

        assert context.persona
        context.execute_steps(u"""
            When I go to Home
                Then I should see an element with id "email" within 2 seconds
            When I fill in "email" with "$email"
            And I press "send-sms"
                Then I should see "We have sent you an SMS with a security code" within 2 seconds
                And I should receive an sms at "$mobile"
                And "token" should be enabled
            When I parse the sms I received at "$mobile" and set "Your Crypho code is {token}"
            And I fill in "token" with "$token"
            And I fill in "password" with "$password"
            And I press "login"
                Then I should see "Crypho" within 5 seconds
        """)

Observe above how the current persona (Gandalf) parses the sms it
receives and saves it as "token". Later Gandalf reuses it to fill in the
two-factor authentication field.

Now that Gandalf is logged in, the test proceeds with Frodo. Frodo will
log in, and invite Gandalf to a private space.

    Given "Frodo" as the persona
    When I log in
    And I click the link with text that contains "My spaces"
    And I click the link with text that contains "The Shire"
    And I press "invite-members"
        Then I should see "Invite members" within 1 seconds
    When I fill in "invitees" with "gandalf@wizardry.com"
    And I fill in "invitation-message" with "Come and join us!"
    And I press "send-invitations"
        Then I should see "Your invitations have been sent" within 2 seconds

Once the invitations are sent we switch back to Gandalf's browser, who
should have received a notification in his browser, as well as an email.
He then proceeds to send an sms to Frodo with the token who completes
the invitation.

    Given "Gandalf" as the persona
    Then I should see "Your invitations have been updated" within 2 seconds
    And I should receive an email at "gandalf@wizardry.com" containing "Frodo Baggins has invited you to join a private workspace in Crypho"
    When I click the link with text that contains "Invitations"
    And I click the link with text that contains "Pending invitations"
        Then I should see "Come and join us!"
    When I set "token" to the text of "invitation-token"
    And I send an sms to "45699900" with body "$token"

    Given "Frodo" as the persona
        Then I should receive an sms at "45699900"
    When I set "FrodoToken" to the body of the sms I received at "45699900"
    And I click the link with text that contains "Invitations"
    And I click the link with text that contains "Enter authorization token"
    And I fill in "auth-token" with "$FrodoToken"
    And I press "Submit"
        Then I should see "The invitation has been accepted." within 5 seconds
        And I should see "Gandalf the Grey has joined the space, invited by Frodo Baggins" within 10 seconds

You can see the test in action on video
[here](http://vimeo.com/63672466/).

There maybe instances where you require personas but do not want a
seperate browser associated with each persona, this can be achieved by
adding the attribute *single\_browser* to the context object (usually
performed in one of the hooks in `environment.py`), e.g:

    def before_scenario(context):
      context.single_browser = True

Setting up a test environment
-----------------------------

Start by installing *behaving* by using either `pip` or `easy_install`.
This will also install dependencies and create the `behave` script with
which you invoke your tests. If you prefer using buildout, clone the
package itself from its repository, it contains already a buildout
configuration.

Typically you will be having a folder containing all your features and
steps. For example a directory structure like the following:

    features/
    features/mytest.feature
    features/myothertest.feature
    features/environment.py
    features/steps/
    features/steps/steps.py

In the steps directory you will need to import the *behaving* steps you
need. You can also define your own steps. So `steps.py` might look like:

    from behave import when
    from behaving.web.steps import *
    from behaving.sms.steps import *
    from behaving.mail.steps import *
    from behaving.notifications.gcm.steps import *
    from behaving.personas.steps import *

    @when('I go to home')
    def go_to_home(context):
        context.browser.visit('https://web/')

In `environment.py` you specify settings as well the things that need to
happen at various stages of testing, i.e. before and after everything, a
feature run, or a scenario run. For convenience you can import and reuse
`behaving.environment` which will perform default actions like closing
all browsers after a scenario, clean the email folder etc.

It is also possible to use `behaving.web.environment`,
`behaving.mail.environment`, `behaving.sms.environment` and
`behaving.personas.environment` on their own, if you don't have need for
SMS for example.

An example of an environment that does simply set some variables and
then rely on default actions for the various stages, might look like the
following:

    import os
    from behaving import environment as benv

    PERSONAS = {}

    def before_all(context):
        import mypackage
        context.attachment_dir = os.path.join(os.path.dirname(mypackage.__file__), 'tests/data')
        context.sms_path = os.path.join(os.path.dirname(mypackage.__file__), '../../var/sms/')
        context.gcm_path = os.path.join(os.path.dirname(mypackage.__file__), '../../var/gcm/')
        context.mail_path = os.path.join(os.path.dirname(mypackage.__file__), '../../var/mail/')
        benv.before_all(context)


    def after_all(context):
        benv.after_all(context)


    def before_feature(context, feature):
        benv.before_feature(context, feature)


    def after_feature(context, feature):
        benv.after_feature(context, feature)


    def before_scenario(context, scenario):
        benv.before_scenario(context, scenario)
        context.personas = PERSONAS

    def after_scenario(context, scenario):
        benv.after_scenario(context, scenario)

The following variables are supported and can be set to override
defaults:

-   `screenshots_dir` (the path where screenshots will be saved. If it
    is set, any failure in a scenario will result in a screenshot of the
    browser at the time when the failure happened.)
-   `attachment_dir` (the path where file attachments can be found)
-   `sms_path` (the path to be used by `smsmock` to save sms. Defaults
    to `current_dir/sms` )
-   `gcm_path` (the path to be used by `gcmmock` to save gcm
    notifications. Defaults to `current_dir/gcm` )
-   `mail_path` (the path to be used by `mailmock` to save mail.
    Defaults to `current_dir/mail` )
-   `default_browser`
-   `default_browser_size` (tuple (width, height), applied to each
    browser as it's created)
-   `max_browser_attempts` (how many times to retry creating the browser
    if it fails)
-   `remote_webdriver_url` (points to your selenium hub url or remote
    webdriver. Defaults to `None`)
-   `browser_args` (a dict of additional keyword arguments used when
    creating a browser)
-   `base_url` (the base url for a browser, allows you to use relative
    paths)
-   `accept_ssl_certs` (setting to `True` will accept self-signed/invalid
    certificates. Defaults to `None`)

You can run the tests simply by issuing

    ./bin/behave ./features

For chrome and docker issues, the code below is useful

    from selenium.webdriver.chrome.options import Options
    chrome_options = Options()
    chrome_options.add_argument('--no-sandbox')
    context.browser_args = {
        'options': chrome_options
    }

Mail, GCM and SMS mock servers
------------------------------

When *behaving* is installed, it creates three scripts to help you test
mail, gcm and sms, `mailmock`, `gcmmock` and `smsmock` respectively. You
can directly invoke them before running your tests, they all take a port
as well as the directory to output data as parameters. For example,

    ./bin/smsmock -p 8081 -o ./var/sms
    ./bin/gcmmock -p 8082 -o ./var/notifications/gcm
    ./bin/mailmock -p 8083 -o ./var/mail [--no-stdout]
