Accelerating API Development, Testing and Delivery with API Virtualisation In an ideal world, API development, testing, and operations teams always work together in perfect synchrony, delivering high-quality APIs on schedule, under budget and completely error-free. But as applications and micro-service architectures increase in complexity, teams often struggle to maintain velocity without tripping over functional dependencies and unwanted behaviours within their solutions. API Virtualisation is an increasingly popular approach for speeding release cycles by developing and testing in parallel. Additionally, API virtualisation enables teams to overcome 3rd party downtime, rate limits and overage fees by removing those dependencies.
