Visual testing has been around for quite some time, yet most development teams tend to focus on unit and integration tests alone. These tests mainly look at the application’s logic, overlooking any potential visual issues at the UI level. By bringing in visual testing, we can catch these visual problems early on and fix them before the product goes live. […]
Percy Unveiled: Addressing Challenges and Grey Areas
Crafting Rust CLI Applications: A Journey with Clap Crate
At Qxf2, our ongoing efforts involve delving into popular Rust crates and crafting tutorials to facilitate seamless adoption and utilization of these crates. As part of this undertaking, we turned our attention to the Clap crate, recognizing its significance as a valuable library for parsing command line arguments in Rust. This blog post aims to provide you with a comprehensive […]
Tcases: Auto-generating API Tests
Most development teams that Qxf2 works with, describe and document their APIs using Open API specification. This means, there is a set structure for folks to write tests. Handcrafting the simple test cases can be cumbersome and time consuming. Given there is a set structure, we started to look out for solutions that could create API tests based on an […]
Integrating CloudWatch Alarms with Skype
At Qxf2, our AWS environment hosts a multitude of applications, so monitoring the AWS services in real time is crucial for maintaining system reliability and performance. We’ve been using CloudWatch alarms to help us watch over our resources, these alarms used to send us emails whenever something went wrong. The problem was, it is often easy to miss these alerts […]
Troubleshooting Common Issues when using Chef InSpec with GitHub Actions
At Qxf2, we have been using Infrastructure tests at our clients for a while now. We recently came up with the idea of adding some infrastructure tests for our own servers and applications within Qxf2. We used Chef Inspec to write and execute our tests. Chef InSpec is a popular open-source framework that helps you test and review your applications […]
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 […]
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 […]
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 […]
Investigating Data Loss: A Forensic Approach
Testing these days spills onto production too. Testers from Qxf2 have been able to show value by knowing how to trace transactions across multiple forensic tools. This post is for testers who have always wanted some insight into how to investigate issues in production but never had the opportunity. Background Testing in production also is a good idea. We were […]
Setting up Synthetic data in Neo4j
Qxf2 engineers are fans of using synthetic data for testing. We have used this technique for years now. But until recently, our experience was limited to SQL. We needed to work with neo4j in one of our projects. There was enough custom Python code and Cypher queries that we had to write as part of creating, backing up and restoring […]
