Integration testing with Python, TestProject.io, and GitHub Actions

Caution None of the testproject.io urls resolve anymore in JAN 2025, I removed all of the broken links. As I continue to build out waylonwalker.com I sometimes run into some errors that are not caught because I do not have good testing implemented. I want to explore some integration testing options using GitHub’s actions. Running integration tests will not prevent bugs from happening completely, but it will allow me to quickly spot them and rollback. 🤔 What to test first? # The very first thing that comes to my mind is anything that is loaded or ran client-side. Two things quickly came to mind here. I run gatsby so most of my content is statically rendered, and it yells at me if something isn’t as expected. For performance reasons I lazy load cards on my blogroll, loading all of the header images gets heavy and kills lighthouse (if anyone actually cares). I am also loading some information from the top open-source libraries that I have created. To prevent the need to rebuild the whole…

🐍 Practice Python Online

When learning a new skill it’s important to practice along the way. In order for me to show up to practice I need to make it easy to show up. An easy way to show up to practice with python is to use an online repl. With these you can try out something quick. Sometimes I see snippets from blogs or tweets and I need to try the out for myself to really understand. When learning a new skill it’s important to practice along the way.

Edit On GitHub

I recently added a button to my blog, and subsequently my posts on DEV.to. It’s the best thing that I have done for it in a while. It makes it so easy to do quick edits. finding errors # I refer back to my old posts quite a bit, sometimes I find errors in them. Honestly most of the time its too much effort to load up my editor make the change and and. It’s not much, but when I am referring to my own post generally I am just trying to get something done and don’t have time for that. The slug # The slug that I am getting from gatsby is formatted as. Note the trailing slash and missing file extension, thats where the comes in. The Full Link # GitHub makes it super easy to form a URL that puts you right into edit mode on the exact post you are looking for. This is format for the URL… you can always figure it out easily by clicking edit on one. The Final Result # Wrapping that URL up in a short snippet gave me the following result. I know better than hard coding the GitHub url in, but I did…

Why use a cms

When first learning to code its very common to hard code everything right into the code. This happens with most folks in just about any language. Whether its HTML or markdown for front end content, or even hardcoding parameters in our backend languages like python, or node.js. 🤷‍♀️ What’s wrong with hard coding everything? # Hard coding everything right into your code makes it really hard for non-technical collaborators to join. It makes it nearly impossible to hand websites off to clients without needing to come back for routine updates. The cms generally come with a rich content editor that feels more like something most folks are used to. There are buttons for changing the font, font-size, adding images, bold, italics, etc. Sometimes I don’t feel technical # Even when you are developing for a technical audience there is a layer of polish that comes from giving them a nice interface to edit their content in. YouTube doesn’t have you manually inserting records into the database to add…

🐍 Parsing RSS feeds with Python

I am looking into a way to replace my google reader experience that I had back in 2013 before google took it from us. I am starting by learning how to parse feeds with python, and without much previous knowledge, it proved to be much easier than anticipated thanks to the library. This is how I used python to parse rss and setup my own custom feed. Install # Install the feedparser library. Get the content # The feed object # The feed is a feedparser.FeedParserDict. For all intents and purposes this seems to just behave like a dict with the following. feed has some general information about the rss feed, but the meat of the feed is in entries. The rest of the keys weren’t all that useful for me at the moment. pulling multiple feeds # I grabbed a few popular RSS feeds that I was familiar with to get started. I checked out the keys, all three had the following keys. Mine also had the full post under, this is because I added an extra for publishing to from an RSS feed. NOTE: dev.to/feed # I…

🤓 What’s on your GitHub Profile

I ran this post on dev.to and got a great response of great examples, check it out.!! 🤓 What's on your GitHub Profile The GitHub profile feature just went live for a subset of users. Simply creating a repo named after your username, and clicking share to Profile on the sidebar will create a custom profile that shows up just above your pinned projects. I am still trying to figure out what to put on mine, but this is what I have so far. I feel like mine is a bit big at the moment, I don’t like that my pinned repos end up blow the fold. updated # I tightened mine up and took inspiration from a few others. Share a screenshot and link of yours on dev. updated again # Updated with a list of latest Twitter followers, using GitHub actions.

🙋‍♂️ Can Anyone Explain Twitter Cards to me?

Can someone explain how or why twitter cards render differently from device to device? I do understand that twitter cards a built from meta tags, the full list can be found in their docs Rendered on Mobile # Mobile Looks fine. Not Rendered on Desktop # On Desktop it is not picking up the image. Twitter Card Validator # The Validator renders the card correctly. I tried the official twitter card validator, as well as heymeta.com, and metatags.io. All look good. Can Cards be updated? # even with a redirect? I tried seting up a pinned tweet that uses a netlify redirect to always keep my latest post up to date. Again this one looks good in the validator, doesnt render the image on desktop, does render the image on mobile, but does not update. I have heard that you need to hit the card validator to update cards? I am not sure if this is true, but for me this is not even upating the card. 👋 Hello, ―――――― I'm Waylon Walker ―――――― I work with data using 🐍 #python and utilize #webdev to 〽visuali…

How I Built My GitHub Profile

I ran a discussion on dev that collected quite a list of examples in the comment section. So many great calls to action, animations, memes, and weird tricks. My current profile # social icons # Upload all of your icons to the repo in a directory such as or, then link them with a attribute like below. I used html for mine, not sure if you can set the in markdown. note I did add a bit of (non-breaking-whitespace) between my icons. Without adding css this seemed like the simplest way to do it. Center # Aligning things in the center of the readme is super simple. I used this trick to align my social icons in the middle. right # For my latest post I floated it to the right with a little bit of action. You may need to play with where you put this in the document, and the size of elements to get things to flow right. redirects # In order to keep my latest post always up to date on my readme I implemented a netlify redirect to always point to my latest post. As a digital gardener this helps me…

SLIDES - understanding python \*args and \*\*kwargs

Python and are super useful tools, that when used properly can make you code much simpler and easier to maintain. Large manual conversions from a dataset to function arguments can be packed and unpacked into lists or dictionaries. Beware though, this power can lead to some really unreadable/unusable code if done wrong. I generally post these as a carousel on LinkedIn based on a full article.

Gracefully adopt kedro, the catalog

Why use kedro catalog? # While using the catalog alone will not reap all of the benefits of the framework, it does get you and your project ready for the full framework eventually. For me the full benefit of the catalog comes when you combine it with the pipeline and dont even touch read/write steps at all. Taking a step into kedro by adopting the catalog first will give you a way to organize all of your data loads in one place, and stop manually writing read/write code, which can be different for each data and storage type. You just don’t need to think about it. iperitive loading style organizes your data all file locations can be quickly identified can be dropped into kedro later “can be dropped into kedro later” Let’s talk a bit more about that 2 Ways to Gracefully adopt the catalog # How do I get started with the kedro catalog add with the code api load from yaml ( recommended) 1. Adding to the catalog with the code api # how to use the kedro catalog code api It is possible to keep…

How to find things in your kedro catalog

kedro 0.16.2 just dropped last week with a long-awaited feature… catalog search! I went as far as monkey patching this into each of my projects. I work jump between a few really big projects that have tons of datasets. Being able to quickly search for what I need is so useful. The Catalog # The kedro data catalog is a key component to the kedro framework. It handles all data loading and saving for you. It is configurable and hackable. Having all your data connections listed in one place make it so easy to pick your project up and move it to a completely new environment. That sweet imperative loading style saves so much read/write overhead. I can load all my data with a single command whether it’s in amazon s3, google cloud platform, or a local file. Kick start a toy project # Just like with most of these articles, I am going to create a conda environment so that I don’t break any existing projects and scaffold up a toy project to learn from. Expect this set of commands to take a few mi…

My first eight years as a working professional.

This day 8 years ago I started my first day as a Mechanical Engineer. I am so grateful for this journey that I have been able to have. There is no way that I could have planned this journey from the beginning. Keep Learning # My initial career plans were down a completely different path. I have been very flexible in taking on a new career path. I have been eager to learn new things and respond to life changes that I never would have imagined. Life Changes # Very severe chronic health issues from my family restricted my ability to travel to the facilities I served as a Mechanical Engineer. I was able to stay strong and make it work. But in the meantime, I was learning new skills that enabled me to be more effective remotely. I was scared. # It was in these times that I found a love for data, and taking action from insights I found with data. I learned how to use python to enable me to be more effective. I did this primarily from hospital waiting rooms and many overnight stays. This gave…

How Kedro handles your inputs

Passing inputs into kedro is a key concept. Understanding how it accepts a single catalog key as input is quite trivial that easily makes sense, but passing a list or dictionary of catalog entries can be a bit confusing. *args/**args review # Check out this post for a review of how work in python. understanding python *args and **kwargs python args and kwargs article by @_waylonwalker All Kedro inputs are catalog Entries # When kedro runs your pipeline it uses the catalog to imperatively load your data, meaning that you don’t tell kedro how to load your data, you tell it where your data is and what type it is. These catalog entries are like a store. You just need to give the key when setting up a node. Single Inputs # These are fairly straightforward to understand. In the example below when runs the pipeline it will load the input from the catalog, then pass that input to the func, then save the returned value to the output catalog entry. List of inputs # Let’s look at an example node…

Master No More

It’s been a long time coming. We use some very harsh language within tech so much sometimes that we become numb to it. It’s time to do my very small part in this movement and purge this language from my active repos starting with this blog right here. Large Refactor At The Command Line this post follows my method of refactoring code bases from the command line, read more about that in this article. c-s-f # First off browsing through the content of my blog I found many references to master. I cannot completely whole-sale find and replace each one of them, because some of them are links that I do not own. Any set of instructions got upgraded from to There were countless cases of examples like this to comb through, but it feels good to have them purged of old language. rename routes # Following yesterdays post, I am going to rename my markdown files /static/_redirects shorteners # redirect posts # redirect external links to repo # More info on refactoring your blog routes with netlify her…

Refactoring your blog urls

I just did a quick refactoring of my JAMStack blog urls. Some didn’t fit with my style, some had that I wanted to switch to, and others were ridiculously long. I’ve been using forestry as my CMS, I write many of my posts there, and sometimes it picks some crazy file names (based on my titles). It was time to refactor. Large Refactor At The Command Line When refactorings similar to this get really big I often need to do some project wide find an replace, I usually do this right from the command line. 🖊 Rename posts change the filename # My post urls are based on the file name of my markdown file, so I can simply go through my filesystem and rename anything I want. From here its probably best to only commit the addition of the new file name, until the redirects clear, but these are all low traffic posts for me so I just commited both at once. Safely redirect without breaking links _redirects ⤴ /redirects # I am hosted on netlify, which automatically puts very ⚡ performant redirects on th…

pre-commit is awesome

I recently discovered the ✨ awesomeness that is pre-commit. I steered away from it for so long because it seemed like a big daunting thing to set up, but really it’s easy. It will automatically run checks for you. In some cases, it will even automatically fix them for you. Out of the box, it will do things like automatically trim extra whitespace, fix file endings, and ensure file sizes are not too large for git.
