Leading Mobile Carrier Speeds Time-to-Market

This company is one of the largest wireless carriers in the United States and Europe. In addition to operating its leading cellular network, the provider has made advancements into mobile banking, web TV and IoT – all with an eye on enhancing the breadth of its service offerings and level of customer engagement.

As customer demand for new mobile services continued to grow, the company’s delivery teams struggled to keep pace. In order to continue to provide the best service, it needed to get its quality engineering (QE) efforts back on the right track.

The challenge
TO embrace new digital services with next-generation capabilities

The carrier has a reputation for providing network excellence, innovative digital solutions, and offering some of the industry’s highest service levels.

But as customer demand for new digital services continued to multiply and new devices and networks enabled next-generation capabilities, the carrier’s delivery teams struggled to keep pace.

The carrier decided to embrace a “shift left” (test early and often) approach to its QE efforts with several key objectives:


Automate a large part of its software and device test footprint to speed cycle time and reduce manual testing errors


Reduce the time and resource requirements involved with testing new service offerings

Platform Compatibility

Ensure the highest service levels possible for users

The Solution

Mobile test automation with Perfecto

Apexon leveraged its expertise in enterprise mobile automation along with its technology partnership with Perfecto to quickly put the carrier’s QE efforts back on the right track. The engagement focused on two key areas:

Customer-branded mobile apps

Customer-branded mobile apps

That cater to enterprise customers and users on the carrier’s cellular network

Android security market releases

Android security market releases

Covering devices certified to work on the carrier’s network. Some key aspects of the solution and deployment included:

Automated test cases

Automated test cases

test cases automation for apps

1,400 test cases automated for two apps on four different platforms (iOS and Android on mobile and tablet)

mobile devices test cases automation

120+ test cases automated on 35+ different devices for the Android security patches

Apexon also overhauled their testing framework which included:

need-based test cases execution

A self-service portal to enable non-testers in the customer organization to independently execute test cases on as-needed basis

daily test execution and analysis

Daily test execution and analysis to ensure quality releases to the end customer

maximize function testing coverage

Parameterized set up and functionality to maximize functional test coverage

automatic failure categorization

Error bucketing (automatic failure categorization)

test execution of automation script for network, system and devices

Generation of network, system and device-related metrics from test execution of automation script

test results integration

Test result integration with TestRail

Use of Kibana

Use of Kibana by (non-technical) subject matter experts for reporting to trigger and manage execution

Use of JIRA

Use of JIRA to manage entire flow to provide visibility across the entire delivery cycle; e.g., requirements, development, delivery, review, acceptance

Apexon leveraged its long-time partner Perfecto to provide the optimal technical solution. This involved re-orienting the statistics used to analyze the software test failures more effectively and efficiently.

Apexon also developed automation scripts to test device behavior in varied network signal strength environments while switching from one network to another; e.g., WiFi, 2G, UMTS, 3G, 4G/LTE, etc. The engagement also included 24×7 support for test execution including daily build release and validation while using a static code analysis tool.
