Testing and QA

ProIDS offers a wide range of testing and QA services. We specialize in testing of high-throughput real-time communication solutions. Our testing and QA specialists leverage deep knowledge of telecommunication protocols and profound experience with test methodologies (we follow ISTQB and PMI) and hands-on approach to test automation.

We deliver comprehensive test-related documentation, such as: Master Test Plans (including test strategy), Detailed Test Plans, Acceptance Test Manuals, Test Reports and others.

Where applicable we provide a full suite of testing and QA tools together with automated test cases in form of test scripts.

Testing Phases – they depend on system scale and scope but typically include:

• Unit testing – white box testing, typically applies when ProIDS develops custom software;
• Module testing – black box testing of particular software module functionality;
• System testing – testing of subsystems which are part of a solution, or a complete system;
• Integration testing – testing of interfaces integration of given solution in the target Customer environment;
• Performance testing – testing of application’s performance and stability, proves that particular software can handle required load;
• Acceptance testing – formal functional acceptance of the solution, which is realized by proceeding according to Acceptance Test Manual;

All testing phases may include several rounds of regression testing, depending on project timeline, scope and solution complexity.

What we test:

• Custom-developed software – software developed by ProIDS on-demand;
• Third party custom software – we verify software developed by third parties which is intended to be hosted on common unified solutions.
• Specific products – COTS software and hardware products, including equipment such as SIP proxies, B2BUAs, SIP media servers, SIP/x gateways, SIP PBX, Diameter Routing Agents and many others.

How we test:

• Test coverage – by using various test coverage approaches we ensure that the final solution meets all requirements.
• Automation – we emphasize test automation and introduce whenever possible.
• Reporting – we follow strict test reporting so that all involved stakeholders have an instant view on testing progress, outcome and improvement areas.

Tools

Depending on scope of a given solution and Customer needs we use various test tools, some of which are listed below. On top we develop our own custom add-ons, utilities and scripts.

Telco testing

• OpenCloud Simulator – proprietary tool which is used for OpenCloud-based NGIN solutions.
• Telestax jSS7 – open source based tool which is used for testing SS7-based protocols such as CAP and MAP.
• SIPP – open source test tool / traffic generator dedicated for the SIP protocol, which uses custom XML scenario files describing complex call flows; it can also generate media (RTP) traffic.
• Seagull – open source Multi-protocol traffic generator suitable for testing IMS SIP-based solutions, as well as Diameter and SS7-based CAP or MAP
• Titan TTCN-3 – open source toolset based on the TTCN-3 (TESTING AND TEST CONTROL NOTATION VERSION 3) standard, which is used among others for SIP and ASN.1 based protocols.

Web testing

• SOAP UI – primarily used for functional testing web services and REST APIs.
• JMeter – tool for performance testing of various types of solutions, such as: web applications, databases, LDAP, JMS, etc.
• Selenium – browser automation framework for testing web applications.
