Smoke test
A brief, shallow test that checks whether a system’s essential functions work sufficiently for further testing or use.
Effective Platform Engineering
A smoke test is a shallow test that checks whether a system or service is broadly operational before deeper testing.
- How it is used
- Uses shallow pipeline checks to establish that deployed services are operational before deeper verification.
- How deep it goes
- Checks container status and startup evidence, then stops short of verifying operating results covered by functional tests.
- Examples
- Demonstrates Running pods, successful startup logs, metrics endpoints, and event-exporter output from Kubernetes services.
- What you can do after
- Diagnose deployment failures early by checking whether containers run and services report successful startup.

Machine Learning System Design
A preliminary test that checks whether a system or component operates sufficiently to warrant further testing.
- How it is used
- Checks ML training pipelines after changes before engineers spend time on deeper testing or experimentation.
- How deep it goes
- Defines a fast, reduced-scale pipeline check and its maintenance tradeoff, while deferring detailed component coverage to unit tests.
- Examples
- Uses a fixture dataset, one epoch, a dummy ResNet, mocked construction, and training and validation loss assertions.
- What you can do after
- Diagnose/debug pipeline regressions quickly and decide whether deeper testing or experimentation is worthwhile.

Learn Docker in a Month of Lunches, Second Edition
A smoke test is a short, focused test that checks whether a software build or deployment performs its essential functions.
- How it is used
- Uses minimal end-to-end checks to verify application builds within a CI/CD pipeline.
- How deep it goes
- Explains the Docker Compose workflow and image choices, but stops short of detailed test design or browser automation.
- Examples
- Demonstrates a PowerShell script, local-image execution, staging-image execution, web requests, and container shutdown.
- What you can do after
- Apply it via Docker Compose and PowerShell to check whether an application starts and responds during a build.

Infrastructure as Code, Patterns and Practices: With examples in Python and Terraform
A small, rapid set of tests that checks whether critical functionality remains operational after a change.
- How it is used
- Provides rapid feedback after changes before teams invest time in the full end-to-end test suite.
- How deep it goes
- Defines the test and gives infrastructure scenarios, but stops short of detailing a complete smoke-test suite.
- Examples
- Uses Cloud Run URL checks, network connectivity, workload completion, and HTTP requests with varying payloads.
- What you can do after
- Apply it via pytest and infrastructure workflows to detect catastrophic change failures before further testing.
