simple-mockforce 0.1.7

A companion package for simple-salesforce that enables the testing of code that interacts with Salesforce's API

Introduction

This library was inspired by moto and mimics some of its design. Mainly, no simple-salesforce code is patched; instead, the HTTP calls it makes are intercepted, and state is stored in an in-memory, virtual Salesforce instance, which is just a globally instantiated class that is created at the run-time of a test-suite.

Installation

pip install simple-mockforce

or, with poetry

poetry add simple-mockforce

Usage

To patch calls to the Salesforce API and instead interact with the "virtual" Salesforce instance provided by this library, add the following:

import os

from simple_mockforce import mock_salesforce

from simple_salesforce import Salesforce


@mock_salesforce
def test_api():
    salesforce = Salesforce(
        username=os.getenv["SFDC_USERNAME"],
        password=os.getenv["SFDC_PASSWORD"],
        security_token=os.getenv["SFDC_SECURITY_TOKEN"]
    )

    response = salesforce.Account.create({"Name": "Test Account"})

    account_id = response["id"]

    account = salesforce.Account.get(account_id)

    assert account["Name"] == "Test Account"

To reset state, you can pass fresh=True, ensuring there's no pollution between tests

from simple_mockforce.virtual import virtual_salesforce


# This will wipe away the account created in the above step
@mock_salesforce(fresh=True)
def test_api_again():
    pass

And that's about it!

Caveats

Case sensitivity

Unlike a real Salesforce instance, the virtual instance will not handle case-insensitive dependent code for you. You must remain consistent with your casing of object and field names in all aspects of the code.

Missing endpoints

The following features are currently not supported:

• the describe API
• bulk queries
• SOSL searches

Queries

SOQL is only partially supported as of now. Please refer to the README for python-soql-parser to see what's not yet implemented.

You should only expect this library to be able to mock the most basic of queries. While there are plans to, mocking query calls which traverse object relationships or that use SOQL-specific where-clause tokens are not yet supported.

Notable mentions:

• be explicit with direction in ORDER BY clauses, i.e., always supply DESC or ASC

Error handling

Error handling is only mocked to a degree, and for some calls it isn't at all. This is because the virtual Salesforce instance does not yet enforce any of the server-side validation when working with a real API.

This means that the virtual instance is much more permissive and loose than a real Salesforce instance would be.

There are plans to read the XML consumed by the meta API in order to enforce more rigidity inside the virtual instance, but this is not yet implemented.

All HTTP traffic is blocked

When using @mock_salesforce, do note that the requests library is being patched with responses, so any calls you make to any other APIs will fail unless you patch them yourself, or patch the code which invokes said calls.
