    >>> from trytond.tests.tools import activate_modules

    >>> today = dt.date.today()

    >>> FETCH_SLEEP, MAX_SLEEP = 1, 100

Activate modules::

    >>> config = activate_modules(
    ...     'account_payment_stripe', create_company, create_chart)

Create fiscal year::

    >>> fiscalyear = create_fiscalyear(today=today)
    >>> fiscalyear.click('create_period')

Create Stripe account::

    >>> StripeAccount = Model.get('account.payment.stripe.account')
    >>> stripe_account = StripeAccount(name="Stripe")

    >>> stripe_account.publishable_key = os.getenv('STRIPE_PUBLISHABLE_KEY')
    >>> stripe_account.save()
    >>> stripe.api_key = os.getenv('STRIPE_SECRET_KEY')

Setup fetch events cron::

    >>> Cron = Model.get('ir.cron')
    >>> cron_fetch_events, = Cron.find([
    ...     ('method', '=', 'account.payment.stripe.account|fetch_events'),
