I was recently notified that an old API key was discovered in one of the repos I own. Even if you remove the sensitive data in a new commit, it can still be found in the Git history.

To remove the API key, I decided to use the BFG Repo-Cleaner for cleansing bad data out of your Git repository history. However, I found myself fumbling around with the BFG CLI and spending way too much time trying to remove the key from the Git history.

That’s when I realized there had to be a better way. As a frequent user of Visual Studio Code, I thought, “Why not create a VS Code extension that simplifies this process?” And that’s exactly what I did.

In 2020, I blogged about associating automated tests with Azure Test Cases. The post had 18 questions, which indicates there is still confusion on how this works, especially how to set it up with Playwright (which was pre-stable release at the time).

In this post, I’ll walk through how to configure both Playwright Test (JavaScript/TypeScript) and Playwright .NET to get test results in Azure Test Plans. Each option uses abstractions built on the Azure DevOps REST API so you don’t have to write additional code to accomplish this.

I was recently tasked with measuring the impact of a Redis cache on an e-commerce site. This was pretty simple with Azure Load Testing, by comparing the results of 2 sites, one with cache, and one without. However, to better exercise the site and understand the user experience, I wanted also to use Playwright.

One of the most frequently asked questions I get is how to test web apps that use Azure AD/Entra ID. Rather than repeating myself, I figured I’d write a blog post to expand on the official docs.

NOTE: the creepy feature image for this post was generated via DALL-E?

Modern web apps introduce some testing challenges — dynamic controls can cause flakiness and unexpected behaviors. This is where the magic of the Playwright locator API can help us build more resilient tests.

Now that Playwright has a fancy new HTML reporter, I wanted to host test results to show the latest state of my GitHub Action test runs. Adding a step to my pipeline that publishes the results to GitHub Pages made this pretty simple.

I wanted to document this after spending a frustrating amount of time troubleshooting getting this setup. I was getting this error when running Terraform Plan:

Error building AzureRM Client: obtain subscription() from Azure CLI: Error parsing json result from the Azure CLI: Error waiting for the Azure CLI: exit status 1: ERROR: Please run 'az login' to setup account.
