Mobile Applications

Mobile application testing or mobile testing is a process by which mobile applications are validated against various requirements as below:

  • Functional testing: application does what it claims to do without any errors
  • Usability testing: application is intuitive and presents a good UX to the end user
  • Compatibility testing: application behavior remains same across mobile OS, form factors, or, if they deviate, they adhere to appropraite platform guidelines.
  • Performance testing: application does not crash over long use, repeated, random user inputs, low battery, no network etc.

To ensure a comprehensive test coverage which can take care of all these parameters is a large challenge for any organization.

HSC has experience in manual and automated mobile application testing for native, webView and hybrid applications on most OS platforms like Android, iOS and Windows. We also have the experience of using open source automation tools such as Appium, MonkeyTalk, Monkey and building test frameworks using TradeFed and Robot.

HSC has developed a Mobile Application Test Automation Framework which can be used as an accelerator for reducing the time to market for customers.

Some Case Studies:

  • Manual and automated functional testing of a native Android based field application which does wireless test measurements for UMTS, LTE, GSM etc.
  • Manual and automated functional testing of messaging related application which is a native Android and iOS application like WhatsApp, based on SIP/Web-RTC protocol
  • Manual and automated functional testing of field application software which is a WebView (HTML5) application to be tested on Android, iOS and Windows 8 devices

Web Applications and Web Services

There are several aspects that are involved in a typical web application or a web service testing to ensure that the web based system is meeting its objective. These are functional testing, security testing, performance testing, interface testing, usability and compatibility testing.

Over the years HSC has developed strong expertise experience in both web applications and web services testing (both SOAP and REST based). HSC’s engineering team has exposure to tools - both open source and commercial, like Selenium, Watir, RSpec, UFT, LoadRunner, Sahi, SOAP UI, Jmeter, Web inspect and others.

We have built an automation framework for web testing  which can be used as an accelerator to help customers test their applications quickly.

Some Case Studies:

  • Manual and automated, functional and performance testing for end-to-end billing and ordering system for a satellite based communication system
  • Functional and performance testing for Network Manager front end tool for routers and switches providing rich GUI  for NMS and EMS interface
  • REST API testing for a large online content delivery chain in entertainment industry
  • Functional and performance testing of a billing and ordering system SOAP and REST APIs


Wireless is an important focus are at HSC in providing R&D services to various Tier1 and Tier2 OEMs and operators in different technologies like UMTS, Satellite Communication, LTE & WiFi.

HSC offers testing services in wireless domains, starting from wireless protocol testing to end-to-end system testing, field testing, integration testing, interoperability and performance testing in GSM, UMTS, CDMA, EVDO, LTE, GMR-3G, WLAN, WiMAX, satellite communications and others. HSC has experience of using different tools for the validation of wireless networks like Spirent, Ixia, signal Generators and analyzers, Nethawk and more. HSC is experienced in setting up and maintaining large scale remote labs at offshore locations.

Some Case Studies:

  • UMTS UE simulator regression and verification testing for validating 3GPP features for network node and load configuration where 128 UEs are simultaneously loading the wireless network
  • EVDO PCF functional and performance testing by simulating thousands of access terminals of PCF node
  • Functional and feature testing for WLAN/WiMax chipsets as per 802.11 specifications for WLAN and 802.16e for WiMax


With the onset of major consumer services in messaging, entertainment and infotainment, multimedia testing is an emerging domain for the software industry.

HSC understands that and over the time has gained rich experience in testing of several OTT player deployments across different platforms like mobile devices, Roku, STB, desktop based, FireTV and other platforms. Additionally, HSC has experience in testing the messaging infrastructure based on Web-RTC and SIP based protocols, at both server and client side.

Some Case Studies:

  • Desktop based OTT player automation and testing
  • MOD/VOD services testing for a big company in home entertainment domain
  • Testing an Android based internet TV system
  • Web-RTC testing and SIP testing for client and server for a larger messaging infrastructure company

Network Applications and Cloud

The fast growing need for developing quick and complex applications and running these applications on reliable and highly available infrastructure has added a new paradigm to testing in this domain.

For this HSC extends its testing services by helping customers in testing solutions like Enterprise SDK, web applications, location based service applications, IN/VAS applications, application level gateways or interworking functions, OSS applications (CRM and billing), NMS/EMS solutions etc. HSC offers testing services like functional, security, reliability, scalability and fail over testing.

In addition HSC offers testing services to validate NFV, cloud and SDN solutions. HSC has extensive experience in testing based on cloud infrastructure like AWS EC2, VMWare, OpenStack, Evolved Packet Core testing, IMS testing and others.

Some Case Studies:

  • Completely owning Product Qualification Testing for OSS billing and ordering system, both manual and automation testing
  • Managing independent QA function in turnkey enterprise SDK development
  • Testing of asset tracking solution
  • Functional testing of CRM and billing solution over Salesforce
  • Testing of a cloud hosted OSS solution for mobile services
