Achieve unmatched testing accuracy with our support for both simulated and real mobile devices, ensuring your network performs optimally under all conditions.

Automated verification:

QiTASC enhances test case development with automated verification capabilities, such as automated CDR verification, which automatically compares charge data records against expected results. This reduces manual verification tasks and increases the accuracy and reliability of test outcomes.

Easy scripting:

QiTASC uses a layered architectural approach that facilitates the development of test cases across different technologies and platforms. This structure supports the separation of test logic from implementation details, which helps to maintain clean and efficient test scripts.

Easy integration:

Easily integrates with open-source tools, enhancing utility and reducing operational friction.

Secure environment:

Secure and isolated environments for multiple clients in a single instance, ensuring data integrity and operational security.

No interruptions:

The framework runs independently of GUI changes, which allows tests to run uninterrupted even with updates to the user interface of the tested software.

Handling of multiple SIMs:

Efficient handling of thousands of SIMs through advanced SIM management features and seamless integration with SIM multiplexers and eSIM platforms.

Regular releases:

Agile development process with bi- weekly software releases, ensuring the framework always keeps pace with the latest technological advancements.

Dynamic adaptation:

Testers can dynamically adjust environment variables, making it easy to adapt test cases to different testing conditions without altering the core script, e.g. APNs, SMSC addresses, etc. This flexibility is crucial for efficient testing across multiple configurations, countries, and scenarios.

Verification for accuracy:

Automated verification of charge data records against predefined rules ensures billing accuracy.

Management features:

The framework includes advanced features for managing SIM cards and mobile devices, which are integral to test case development in telecommunications. This integration allows for sophisticated scenarios involving multiple SIMs and devices, providing a more realistic testing environment.

Future development:

The framework architecture is designed to be extensible, allowing easy incorporation of new technologies and protocols.
This means that as telecommunications evolve, so too can the test cases without extensive overhauls or compatibility issues.
