Two ways to test software with feature flags

Feature flags offer a dynamic way to control software behavior at runtime, reducing deployment risks and enhancing flexibility across the development pipeline. The text explores two primary approaches to testing software with feature flags: the "mock" approach and the "platform" approach. The mock approach involves creating a separate instance of the flag solution, allowing for isolated testing without dependency on the actual platform, making it ideal for unit tests. In contrast, the platform approach integrates the test suite directly with the flagging solution, which is beneficial for integration tests by allowing different environments to manage flags independently, though it may face challenges with cloud solutions. Both methods have unique benefits and complexities, with the mock approach requiring careful management of flag states and the platform approach benefiting from tools like Unleash's Edge proxy to optimize performance and offline capabilities.
