At Qxf2, we are excited to delve deeper into Solid technology and explore its potential. This is my second blog post discussing Solid Applications. In my previous blog, I shared about building a sample solid app. This application takes a WebID as input and returns the Profile Name and Friends list for that WebId. In this post, I will talk […]
Testing Solid App with Molid Mock Server
Testing OpenAI Whisper with different accents
At Qxf2, we did some black box testing on OpenAI Whisper – a tool that does speech recognition well. OpenAI Whisper is also capable of language detection and translation. This model can be tested in various ways, by adjusting different voice attributes such as volume, pace, pitch, rate, etc. However, in this particular case, we have chosen to test it […]
Contract Testing: A detailed introduction
Qxf2 has been using contract tests at our clients for a bit now. So we decided to write a series of blog posts to help beginners get started with contract testing as often times testers find it difficult in understanding the contract testing workflow and methods. In this series we will take you on a journey from knowing nothing about […]
Real-time Data Streaming: Neo4j to Flask using Kafka Connect
This post is meant for testers who have to work with Apache Kafka. In this blog, I will show how to build a real-time data streaming pipeline to capture data from Neo4j and stream it to a Flask app by using Kafka. The post has a lot of information so even folks with just superficial knowledge of Apache Kafka can […]
Building Custom Operator in Airflow for external API calls
In this blog, I will show how to build a Custom Operator in Airflow to make calls to external APIs. As we do this, we will see how to use secrets in Airflow, make tasks communicate with each other and interpret the output of an SSH Operator. Although this blog refers to posting messages to Skype, all it does is […]
Add Google Sign-In to your Flask app
Recently, I integrated SSO with Google Sign-In into a web application using the oauthlib library. While working on this project, I found plenty of resources on SSO and oauthlib separately, but struggled to find a tutorial that could guide me through the setup of Google Sign-In using oauthlib in a timely manner. Therefore, I’ve written this post to provide a […]
Testing AWS Lambda Functions with Batch Messages
We find most testers just run the most basic tests on Lambdas. One technique that has helped us discover more bugs when testing Lambdas at Qxf2 is to send batch messages to the SQS that triggers the Lambda. Often times, when you (the tester) send batch messages and “something goes wrong”, you need to be able to triage the cause […]
Combining Rust and Py03 with Python
Recently, Qxf2 has been transitioning to Rust and has been writing many blogs on various topics related to Rust. The main aim of these blogs is to document our progress. In this post, I am writing about how I used Py03/maturin tool to call a Rust library from Python. We have initiated a Rust-based project called “meme-generator” to generate attention-grabbing […]
Parameterize Tests in Rust: rstest
This post will discuss how to parameterize tests in Rust. Qxf2 likes the fact that Rust makes testing a first class citizen of the language. It provides a test runner out of the box. However, coming from Python land, we missed one feature – test parametrization. So went about looking for crates that could help. We have found rstest to […]
Rust Selenium Tests for Beginners
I created a repository of working examples for test automation on the web UI using the thirty-four crate. Beginners often have trouble finding good articles with fully working Rust code, especially professional testers who are learning the language along with UI automation. Therefore, I created something for this niche. If you are new to Rust testing and wondering how to […]
