Solvd Inc is involved in all QA tasks that we do across the board. Their team brought in tools and information frameworks they had already established in order to manage similar systems. They are the main execution drivers on all of our regression testing and on all of our development projects as well.

How we Solved these problems…
- We followed strict security protocols
We used a separate Wi-Fi network with a white-list of IP addresses (a common practice in Fintech apps), to meet the special security requirements. - We simulated the third-party interactions
Solvd’s engineers developed Yutil, a tool that supports JSONs. This allowed us to accurately simulate the third-party interactions and changes associated with bank accounts, credit scores, and cashback cards without affecting the level of production. - We developed a private mobile cloud
We decided to build a private mobile cloud using Solvd’s MCloud solution. The cloud consisted of real devices, including 36 iOS and 38 Android devices dedicated solely to the Nerdwallet project. Our engineers provided full support for the cloud, including simultaneous support for 14, 15, 16 iOS and 9-13 Android versions. We also developed special scripts that were tested rigorously to ensure stability and optimal functionality. - We applied multithreading and supported test case updating
By applying multithreading and supporting regular test case updating, we achieved an impressive everyday capacity: 720 deep links for Android/iOS, 1000 unique tests for mobile, and 700 DataProvider tests. These efforts allowed us to provide exceptional support to our clients and deliver a reliable and high-quality product.
