Mocking, Python, Pytest

Ok this is going to be a collection of notes to self. This post does a good job of summing up some mock patterns with PyTest. I then had to mock the Snyk client which depended on the Requests library. I chose not to mock the requests library but the methods in the snyk library. The thing was the method I mocked returned the “Response” object and I wanted to use the json() feature of that object/class to return the results.

Windows Dev Box Try 3 2020

Yes this is try number 3. See here for the first 2 goes at it. With WSL2 out and a great laptop I wanted to give this another try. MariaDB Even though the install is super simple see https://alfrednutile.info/posts/267 I still end up having to do: $ sudo mysql -u root # I had to use "sudo" since is new installation mysql> USE mysql; mysql> UPDATE user SET plugin='mysql_native_password' WHERE User='root'; mysql> FLUSH PRIVILEGES; mysql> exit; $ service mysql restart To allow me to then use this command, for example maraidb -uroot -proot otherwise I have “Error connecting on localhost” type errors.

Using Python Lambda behind and ALB

Just a quick note to self about ALB and Lambda. When using Lambda behind and ALB for routing your response has to be formatted properly else you will get a 502. https://pypi.org/project/alb-response/ solved this problem. from alb_response import alb_response def lambda_handler(event, context): response_dict = process_the_event(event) return alb_response( http_status=200, json=response_dict, is_base64_encoded=False, ) The results are easy enough to do by hand but I had a bit of time really finding out the format to respond with other than JavaScript and that casing there was a bit confusing.

Suggestions Around Building a Good Development Team in Parallel to Building a Good Product

I’m not a great programmer; I’m just a good programmer with great habits - Kent Beck. Behind any project there has to be a processes in place to build a culture of good coding habits for developers and a process to help “enforce” it. Without such a foundation in place the product will never result into a long term sustainable solution. Below are some items I would like to highlight that I believe can help make a solid application and grow a solid team.

Lambda Tips

@WIP Taking advantage of a running Lambda function and it’s state https://aws.amazon.com/blogs/compute/sharing-secrets-with-aws-lambda-using-aws-systems-manager-parameter-store/ under the section Lambda function has a nice “trick” of setting above the class app = None then later on it will see if that is set def lambda_handler(event, context): global app # Initialize app if it doesn't yet exist if app is None: print("Loading config and creating new MyApp...") config = load_config(full_config_path) app = MyApp(config) return "MyApp config is " + str(app.

Mocking in Python

Serious note to self. I wanted to mock the Github module for python. My simple class will get the ID of the team. from github import Github, Team from dotenv import load_dotenv import os import sys import json class GetTeamId: def __init__(self): load_dotenv() self.team_id = 5555 self.token = os.environ.get("GITHUB_TOKEN") self.client = Github(self.token) self.org = self.client.get_organization('FooBar') def handle(self, team_name): teams = self.org.get_teams() for team in teams: if team_name == team.name: print("Team id", team.
