Sandbox testing works well when your team controls both sides of the integration. You define the service, you define the mock, you know exactly what the sandbox should return. That setup holds up fine for internal microservices and first-party APIs. It starts to break down when you don’t own the dependency. Payment processors, identity providers, SMS gateways, banking APIs, shipping integrations—these are services your system depends on but can’t fully replicate. Their providers give you a sandbox environment, but that sandbox is a simulation they maintain, not a mirror of what production actually does. The gap between the two is where production incidents are born. Sandbox Drift Is Quieter Than You Think Teams writing integration tests against third-party sandboxes are placing a bet. The bet is that the sandbox accurately reflects how production behaves today, not six months ago when someone last checked. That bet loses more often than teams expect. Provider sandboxes l...
Amazon Web Services (AWS) this week added an open source workspace for its Kiro artificial intelligence (AI) coding tool that enables application developers to asynchronously assign tasks to an AI agent that is capable of autonomously performing tasks, such as testing code as it is created, in a way that maintains context across multiple sessions. Darko Mesaros, a distinguished developer advocate at AWS, said the Kiro Crew workspace is also capable of creating reusable AI skills by observing the tasks developers assign to Kiro as they write code. Kiro Crew orchestrates agents using the Agent Client Protocol (ACP) to ensure every step is observable in real time as sub-agents are spawned. For example, developers can also hand off a ticket queue to Kiro Crew for it to triage issues and flag what needs their attention or ask it to investigate the root cause of an incident while a developer continues to work on another task. An Activity view shows each agent’s reasoning, every tool call,...
