Our client is one of the leading North American telecom and datacom solutions company.

Our client was looking at a partner who could perform an independent 3rd party Verification of its GSM-R products and also conduct the customer acceptance testing. The partner was also required to conduct the validation of 3rd party products into their customer’s network.

For a product like the GSM-R product of our client a normal System integration testing would not suffice, given the safety and criticality of the railway network. Wipro adopted the concept of negative testing, along with the system integration testing, to test the robustness of the system.
