Comprehensive QA: Electric Vehicle Charging Station Testing

Client Overview

In the rapidly evolving electric vehicle (EV) industry, a leading company in the EV charging network sector embarked on a significant expansion. This expansion aimed to integrate advanced fleet charging capabilities into their already extensive network of charging stations, marking a critical phase of growth and transformation.


The expansion introduced complex challenges, particularly the integration of multiple critical systems: Driivz for management, Reportal for analytics, and a user-focused mobile app, all requiring seamless interaction with the core Apollo GraphQL. A crucial aspect of this expansion was the need for comprehensive quality assurance testing to ensure error-free integration. This need presented not only a technical challenge but also a business imperative, as any disruption or failure in the system could significantly impact customer trust and the company’s market reputation.


Approach: Our team conducted an in-depth analysis of the client’s existing systems and organized their extensive test cases using TestRail, a test case management tool.


Test Case Automation

We automated approximately 80% of the test cases with CodeceptJS. This approach streamlined regression and smoke testing, ensuring seamless integration of new updates.

Performance Testing

Performance testing was conducted using K6, a JavaScript tool, to ensure the system’s robustness under high loads and its ability to meet both current and future demands.

Business Results

  • Operational Efficiency Leap: The automation of test cases led to significant improvements in operational efficiency, reducing manual efforts and accelerating testing cycles.
  • Deployment Success: A 90% success rate in deploying improvements highlighted the enhanced reliability of the system and ease in rolling out new features.
  • System Stability Reinforcement: Addressing a major architectural issue strengthened the overall system stability, preparing the network for future challenges.
  • User Experience Enhancement: The mobile app rating increased dramatically from 1.8 to 4.6, indicating enhanced user interface and functionality, and thus, increased customer satisfaction.
  • Comprehensive Quality Assurance: The documentation of over 2,000 test cases provided a thorough basis for ongoing system evaluation and improvements.

Impact Summary

The implementation of our solutions significantly reduced both business and technical risks, as evidenced by the elimination of release defects and improvements in code quality and API performance. These advances contributed to enhanced system robustness and customer satisfaction.


With these improvements, the client is now well-positioned for continued growth and success in the competitive EV charging network market. The significant enhancements in operational efficiency, system stability, and customer experience lay a strong foundation for future expansions and innovations.

These achievements bolster the client’s market position and reinforce its reputation as a leader in technological advancement and customer-centric service.
