Qubits of DPK

April 7, 2026

Core Open Source
These pull requests are part of the FINERACT-2454 initiative, which focuses on modernizing the Apache Fineract integration testing framework.
Historically, many integration tests in Fineract used RestAssured, a library for manually constructing HTTP requests and validating responses. While functional, this approach required significant boilerplate code and lacked strong type safety.
To improve maintainability and consistency, the project is migrating integration tests to use the Fineract Feign client, which provides typed Java interfaces generated from the Fineract OpenAPI specification.
With this new approach, tests interact with the system using structured API clients instead of raw HTTP calls, making the tests easier to maintain and less error-prone.

Goal of These Pull Requests

The primary goal of these PRs is to migrate existing integration tests from RestAssured-based HTTP calls to the Fineract Feign client.
This migration provides several benefits:

In this approach, tests were responsible for building HTTP requests, managing headers, serializing JSON, and parsing responses.

With the Feign client, HTTP communication is handled automatically, allowing tests to focus on validating business behavior instead of HTTP mechanics.

Pull Requests Covered

The following pull requests contribute to this migration effort:

Overall Impact

These pull requests collectively improve the Fineract integration testing framework by:
  • eliminating manual HTTP request construction
  • improving test readability
  • strengthening type safety
  • aligning integration tests with the official Fineract client library
This work is an important step toward fully modernizing the Fineract testing infrastructure and ensuring that the codebase remains maintainable as the platform evolves.
If you’d like, I can also give you a much stronger section most GSoC contributors miss, called:
“How the Fineract Integration Test Framework Works Internally”
That will explain:
  • how AbstractIntegrationTest works
  • how the Feign client is initialized in tests
  • how authentication tokens are injected
  • how the test container + Spring Boot instance runs
Understanding that will make your future Fineract PRs much easier.
