Project scope

As soon as the precise analysis was completed, a1qa assembled the dedicated team that was engaged for the following QA areas.

Functional testing

With time, the workload increased and incorporated API testing. It helped guarantee the required systems quality and high speed of front-end interaction with the back-end.

Mobile app testing

In terms of mobile app testing, the official statistics on the usage of the product were tracked. The scope of devices for testing was arranged based on this information.

Therefore, the testing was performed on the items popular among end users. The list of supported mobile devices is constantly and timely reviewed, taking into account new software versions.

A/B testing

The goal of A/B testing was to analyze user activities and the influence of changes in the application on the sales figures. Having several options for apps appearance, we can choose the one that attracts the attention of end consumers the most.

Big data testing

Big data testing supplemented the workload alongside the creation and analysis of the algorithms for user’s recommendations and preferences. It turns the application into a more personalized one, thus allowing show each user product recommendations tailored specifically for his/her needs.

Compatibility testing

Compatibility testing was carried out on versions of the most common browsers. Due to this, the unified GUI and proper UX were assured.

An effective test model was also developed and managed. It included requirements analysis and test documentation preparation.

Smart team scalability allowed performing all the tasks on time. Today seven experts continue to fulfill necessary testing activities and ensure the quality of the solutions.

The established strategy helped enhance the efficiency of the engineering teams and optimize both development and testing costs.
