Black-box testing approach

The safest and most effective way to test your product with no onboarding. This method allows testing functionalities without any knowledge of internal code structure, implementation details, internal paths, and access to the database. 



Highlight points of improvement that potentially were missed because of different development factors such as not clear requirements, deadline pressure, etc. 



There is no risk of data leaks as we won't need any access to code or database. Also, on-demand, we may sign a non-disclosure agreement to protect your interests. 



No onboarding process is needed, an engineer can start working right away after the first call. An extended report will be provided within 3 working days (24 hours)



Users “don’t care” how a system is coded and expect to receive an appropriate response to requests. This technique allows deep dive into what your customers are actually facing while using a product and how they feel about it.
