The system under test was aimed at tracking the activity of the e-commerce solution members on both the website and client's mobile applications. The solution contained offers of the most desired brands in women's and men's fashion, home, travel, kids, etc.
In terms of testing, it was represented by a set of databases with data collected and processed by special jobs. The data was stored in nonrelational database and was constantly exported to DWH (relational database) in the aggregated state.
A1QA was focused on testing the validity of the data that had been collected, processed and stored in the system. We checked that no information was lost, oversupplied or stored incorrectly.
In addition, A1QA tested the libraries that were integrated into the customer's website and collected information. The tracking system didn't have its proper UI.
