About project

Owned by Therapy Brands, the Catalyst web app is an advanced solution for BCBA therapists. It collects, sorts, and processes behavioural data in one place, as well as provides different reports, visual graphs, and document printing capabilities. Using conveniently configured informative widgets, reports, and even email updates, therapists can monitor the health status of their patients.

The Catalyst mobile app is designed for patients to enable them to send health data directly to the web app, where assigned therapists can analyze it and prescribe appropriate therapy methods.

Our engagement

Our QA engineers quickly familiarized themselves with the project and started optimizing the QA process to ensure the timely delivery of a high-quality product.

Together with a project manager, our QA specialists created detailed specifications with clear acceptance criteria to speed up the development process and prevent possible errors before they emerge. Throughout our collaboration with Catalyst, we created 150 Confluence pages and 60 detailed user stories.

By holding daily 15-minute meetings, we fostered collaboration within the team, eliminated possible misunderstandings, and kept the task completion schedule on track.

The QA engineers compiled a flexible checklist, which was updated every time new features were added. Later, they designed a suite of detailed test cases from scratch. It included about 1000 detailed test cases that enabled newly onboarded QA engineers to get up to speed. This greatly streamlined their integration into the project.

The QA team managed to meet the deadline. The first product version was ready even a week before the scheduled release. As a result, the QA engineers had a couple of days to prepare a demo and help the project manager with app release procedures on Google Play and the App Store.

Since the investor and beta users provided positive feedback, we continued working on the next releases. We refined and fully stabilized the QA process. Running checklist-based smoke tests for each new web portal and application build helped identify and fix critical bugs — 25% of all bugs found — during feature development, saving time and costs.

Our experience and profound knowledge of functionality allowed us to troubleshoot almost any issue and even predict some of them.

Using DeviQA’s extensive device fleet, we tested the mobile app on all supported iOS/Android versions, including beta versions, to ensure that it worked flawlessly on every popular tablet and phone. The web portal also underwent thorough testing across all required browsers and resolutions.

As we worked on the project, all versions were released on schedule.

Services provided

Web testing

Most of the tests were executed during the integration of new features and functionality into production. Smoke tests were run for every new build to detect blocker bugs or server errors early. Backward compatibility tests and synchronization tests were executed to ensure an exceptional user experience. Also, we regularly updated smoke tests as the software was developed rapidly.

Mobile testing

We tested critical app areas on mobile devices and verified data synchronization with the web portal. Smoke tests for the iOS/Android applications ran on various smartphones and tablets. We identified a lot of blockers and prevented crashes caused by numerous merges.

Dedicated QA team

Two senior manual test engineers from DeviQA worked as a dedicated team and conducted manual functional and non-functional testing using Device Farm, Amazon AWS, VMWare, BrowserStack, Android Studio, and real physical devices. Also, beyond creating and updating test documentation, they executed API testing with Postman. All bugs were tracked and reported in Azure DevOps.
