I tested DALL-E for a specific real-world use case. I wanted to see how good it was for producing single panel cartoons. My testing has uncovered several promising aspects, some problems that need to be addressed and an interesting testing technique for DALL-E and ChatGPT like applications. I tried summarizing my findings in a blog post like an engineer would. […]

State of testing survey 2023
Please participate in the annual ‘State of Testing Survey 2023’ conducted by PractiTest. To participate, please follow this SURVEY LINK. The survey is full of questions relevant to the testing industry. Qxf2 engineers love reading the results of the survey. The survey data says a lot about the direction of our industry. You can even use some portion of the […]
Transitioning to testing loosely coupled microservices
Testing loosely coupled microservices, at least for me, has proven to be much more challenging than testing monoliths. I feel like a beginner again – especially when there are many teams and many independently deployable services. I often feel overwhelmed with how much there is to consider! In this post, I present a mental model that is helping me think […]
Decode an SQS message within a lambda using Rust
I recently wrote a lambda in Rust that needed me to decode an SQS message and use it within the lambda. This post will help fellow Rust newbies that are trying to decode an SQS message and use it within a lambda. The heart of this post is simply converting a string to a JSON – so please skip this […]
Gradual familiarity as a learning tool
Most QA jobs offer daily opportunities to learn new things every day. Yeah, even the job you are at right now! We get introduced to new technologies and ideas that our colleagues work on. News about our competitors trickles in. We hear things during water-cooler conversations with coworkers. Our colleagues share interesting articles about technology. And so on. But we […]
A hands-on QA training program for fresh graduates
Qxf2 Services is conducting a hands-on QA training program for freshers. The training program is practical and resembles real-work you will do as a tester. We do not follow the traditional teaching method. We believe in learning by applying and solving real-world problems. During the course of this program, you will test real applications, shadow senior QA engineers and work […]
Flask app with a GraphQL API, JWT Authentication and SQLAlchemy
I wrote (and open sourced) a Flask app with a GraphQL API that was implemented using Graphene. The application is similar to the official Graphene example but includes the following: 1. JWT authentication 2. An example of filtering 3. A minimal amount of data for people to tinker with the app This article is suitable for: a) Testers looking to […]
How to conduct ‘Round 2’ interviews at Qxf2
Qxf2 reserves Round 2 of our three-round job interview solely to evaluate if the candidate can learn and apply new concepts quickly. During this round we use one of approximately fifteen exercises. This post goes into great detail on how an interviewer is supposed to conduct Round 2 when using the ‘Fork a repository and fix an error’ exercise. Interviewers […]
Testers, practice testing a machine learning algorithm!
Testers, you now have an app you can use to practice testing a machine learning algorithm. We have written and hosted a simple sentence classifier for testers to practice testing a machine learning algorithm. Play with it and let us know what fun bugs you discover. Hint: Testing this app is fun because there are several bugs that are not […]
The Weather Shopper application – a tool for QA
Qxf2 has been using a web application called Weather Shopper to train our interns on Python and Selenium, interview candidates that list GUI automation as a skill on their resume, validate the capabilities of new GUI automation frameworks, etc. While we shared a write up about this tool several months ago on Reddit, I realized we hadn’t shown it to […]
