SSL has been providing services in the area of verification and validation to several technology companies. By virtue of our association with these companies SSL has gained strengths in end-to-end testing that include feature testing, test automation, performance testing and tuning and optimization.
SSL is a testing solutions provider in platform and products space with strengths in the mobile and wireless technology space. SSL specializes in standards based compliance test solutions and white box test development (For e.g. unit tests).
SSL has partnered with Testing Technologies; a market leader in customer-oriented testing for standards based technologies. All test development tools developed by TestingTech, fully supports TTCN3, the only international standardized test language for complex test systems and solutions. It is standardized by ETSI (European Telecommunications Standards Institute) and ITU-T (International Telecommunication Union -Telecommunications) and is both technology and platform neutral.
SSL test solutions and services include:
- Standards based compliance kits development in Java
- White box testing solutions for Java based products
- Compliance testing solutions for VoIP implementations using TTCN
- Training and Technology consulting
- Implementation of ready-to-use test suites including:
TT suite - VoIP
TT suite - IPv6
TT suite - MOST
SSL is committed to building competence and provide testing solutions based on the emerging technology TTCN3 – considered to be the most powerful test language that provides flexibility in designing and maintaining test software.
SSL’s experience in off shoring combined with the power of expertise in TTCN3 can help in providing a basic testing service or in developing a platform or system independent solution.
These solutions cater to applications in the areas of mobile communications, Broadband technologies, Cordless phones, Smart Cards,internet protocols, wireless LANs, Automotive applications and middleware platforms.
SSL offers:
- Standards/Specification based Test development (Compliance and Unit tests)
- Automated and distributed test development and test management
- Testing during the entire SDLC cycle of product/platform development
SSL believes in long-term partnerships and offers a customer-centric model to solve its client's technology challenges and realize their business goals. SSL's involvement with customers extends from early-stage of requirement testing to final stage of deployment and product testing. SSL specializes well evolved processes and methodologies to produce a reliable result that gets the software to market on time and on budget.

- Precise execution algorithm (operational semantics)
- Test suite and test system control
- Encoding information and other attributes (including user extensibility)
Benefits
- The test language is specifically designed for testing
- Support of systematic testing and test automation
- Speeds up test case design on the front-end side and reduces effort maintaining test suites due to high level of reusability
- Implementable via standardized interfaces (TRI/TCI) into existing systems
- Guarantees high safety of investments due to TTCN-3´s bright area of application test support and a common methodology on a standardized level
- TTCN-3 focus not only on conformance testing, support of load/stress testing
- Low investments for training and knowledge transfer
- Fast access to already standardized TTCN-2/TTCN-3 test suites (B-ISDN, UMTS, SIP, H.248, etc.)
- Free available editors for TTCN-3 on the market
