Our engagement

At the project's outset, there were no established QA processes. The DeviQA engineers took the initiative to create all the necessary initial test documentation. They closely collaborated with a project manager to define the ticket flow for the redesign project and testing procedures. In about three months, the initial test documentation was successfully developed, forming a strong foundation for subsequent stages of the redesign project.

Then, an initial test suite was created in TestRail. It included around 1,000 test cases for features with approved requirements.

Recently, we have introduced test automation using Cypress, which is highly effective for smoke tests and a portion of regression tests. These automated tests comprise 75% of all automated test cases and speed up the smoke testing process by threefold.

Test automation brought substantial value to Application Performance Management (APM) efforts. It streamlined testing processes and gave the manual QA team more time for testing new features, creating test cases, and maintaining existing ones. This increased capacity enabled faster delivery of new functionalities and bug fixing, reducing the time needed to progress from the testing environment to production deployment by 2-3 times.

The DeviQA team also successfully implemented two load test suites—one for the legacy website with 104 samplers and another one for the redesigned website with 188 samplers. These suites were organized into six-thread groups based on functionality, aligning with the target actions per hour. These load tests enabled the client to identify and address issues that could affect the website's performance, speed, or usability under heavy loads. Additionally, results from these tests were compared with the performance of the live production website to ensure a seamless transition to the redesigned website upon its completion.

The efforts of the DeviQA team have streamlined the QA process, enabling the detection and elimination of unexpected bugs.

Services provided

Test Automation

The DeviQA team used Cypress to comprehensively cover the core app functionality with automated tests. These tests encompass 75 E2E scenarios, ensuring thorough validation of all user-interaction points. Furthermore, we have seamlessly integrated our testing suite with the Cypress Cloud solution for enhanced reporting and statistical analysis. To improve flexibility, we have configured the suite to run effortlessly across all available environments within the redesign project, eliminating the need for additional configurations. In addition, we have thoughtfully provided clear instructions for the QA team, enabling every team member to easily execute tests on their own machines, promoting efficiency and collaboration.

Load Testing

Our team has successfully implemented load test suites for the legacy and redesigned websites, utilizing usage analytics data provided by our customers. These load tests have been thoughtfully configured to simulate a comparable load aligned with the average statistical actions such as playlist creation and track playback per hour.

We meticulously collect results of load testing in both HTML and CSV formats. This data enables us to quantitatively measure and compare the stability and APDEX (Application Performance Index) of both websites, facilitating informed decision-making and performance optimization.

Performance Testing

Our QA engineers carry out performance testing, recognizing its vital role in the software development lifecycle. This essential step allows us to pinpoint and rectify performance-related issues before deploying the application to production.

Our primary objectives are bottleneck identification, user experience improvement, downtime minimization, and failure reduction. By achieving these goals, we guarantee that the application maintains its speed, scalability, reliability, and efficiency, ultimately delivering a superior product to our users.

Web Testing

The DeviQA team has achieved a comprehensive test coverage by thoroughly testing various vital and critical components of the application. Approximately 80% of the app functionality is covered with test cases as of now.

Through meticulous usability testing and feedback analysis, we successfully identify and address user interface issues. Additionally, the execution of load testing lets us achieve a significant reduction in load times, thereby enhancing the overall performance of the application.

To safeguard against unexpected issues, we have expanded our regression testing suite and introduced partial automation, guaranteeing bug-free releases and a high level of software quality.

Dedicated QA Team

The DeviQA team is an integral part of the client's in-house QA team. Our two manual testers and one automation tester are responsible for feature verification, maintenance of both manual and automated test suites, test documentation creation, and execution of load and performance tests.

Our step-by-step improvements have allowed the project to seamlessly and rapidly deliver new features.

The development team is primarily based in the US time zones, and our QA team covers a wider range of working hours due to being based in Eastern Europe. This allows us to safely deploy new releases and validate them when app users are inactive, minimizing disruption and ensuring a smooth user experience.
