In previous blog, we tested OpenAI Whisper for English language with different accents and observed it did great job. We also provided details about how we generated audios, setup and test details. In this blog, we attempted to test OpenAI Whisper’s capability to transcribe and translate Indian Languages. At Qxf2, our teammates work from different regions of India, and everyone […]
Testing OpenAI Whisper with Indian Languages
Read and Write csv data using Rust
This post will discuss how to read and write csv data using Rust and the csv crate. We are aiming this at testers who are trying to do useful things with Rust just like us at Qxf2. The two most common operations a tester working with csv would like to do are: reading csv data and dynamically creating csv data. […]
Introduction to Bi-Directional Contract Testing
In our previous blog we gave you an introduction to contract testing, explained Consumer-Driven Contract Testing approach ,setting up Consumer-Driven Contract tests, using Provider states and some of its drawbacks as well. In this blog we will introduce you to the concept of Bi-Directional Contract Testing. We will also show you how to setup Bi-Directional contract tests with an illustrative […]
Testing Solid App with Molid Mock Server
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 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 […]
