The request timed out after five seconds. The application said context deadline exceeded. The dependency was healthy, its dashboards were green, and its own latency histogram showed nothing above 30 milliseconds.

AI chatbots are transforming how people interact with digital products, but they also introduce new accessibility challenges.

Design, document, and verify APIs across OpenAPI, AsyncAPI, GraphQL, and MCP. gRPC and A2A support coming soon.

Misconceptions about microservices load testing are common, especially for teams moving from monolithic systems. It’s tempting to believe that simply scaling infrastructure or running legacy load tests will reveal the same issues and provide actionable results. However, distributed, cloud-native architectures introduce new complexities and risks that demand a different approach.

Katalon's library of testing skills for AI agents holds 13 skills. Building it produces 124 files. The 13 skills are the actual work: how to plan a test cycle, how to design cases from a requirement, how to read a failing run and decide whether a release is safe. The other 111 files are packaging. Four of them arrived this month and they are the subject of this post.

Every SRE team operates services it cannot see into: a vendor binary, an inherited legacy deployment, a container whose owning team dissolved two reorgs ago. The routes are undocumented, the dependencies are unknown, and when a request takes 130 milliseconds nobody can say whether that time is application work or a wait across a network boundary.

Website monitoring often feels like choosing between casting a net or wielding a spear. Cloud-based monitoring is your fishing net: you deploy it broadly, covering vast swaths of digital water, capturing issues wherever they occur. It’s automated, relentless, and covers every corner of your online presence, from global uptime to minute performance blips. On the other hand, on-premise monitoring is the spear – deliberate, targeted, and controlled.

At Datadog DASH in the spring, the Tricentis NeoLoad team met folks in all types of roles – developers, test engineers, CoE leads, and SREs – and one recurring theme we found was that SREs often didn’t know much about how performance validation happens at their companies. That’s a fair division of labor. Seemingly, the performance team’s work would be related but not mission-critical to the infrastructure team’s. But that’s not entirely true.
