integration-testing

When to use

Load this skill whenever tasks include:

• authoring or debugging pipeline test fixtures (.log/.json inputs, *-expected.json output, config files)
• setting up or debugging system tests (_dev/test/system/, _dev/deploy/, mock APIs, 0-hits failures)
• writing script tests for failure paths, API error handling, or package upgrades

When not to use

Do not use this skill as the primary guide for:

• ingest pipeline processor design and architecture (ingest-pipelines)
• CEL program development (cel-programs)
• broad elastic-package command selection and stack lifecycle (elastic-package-cli)

Reference files — load the one that matches your test type

System test input-specific references

In addition to the generic system-testing.md, load the reference file matching your data stream's input type:

When an integration supports multiple input types, load the generic reference plus each applicable input-type reference.

When working across multiple test types in one task (e.g. creating a new data stream end-to-end), load all applicable reference files.

The orchestrator dispatches subagents by passing this file's path in the task prompt; the subagent reads it itself in its own fresh context. Do NOT embed/paste its contents into the task prompt.
• references/builder-system-test-subagent-guidance.md — subagent operating manual for running elastic-package test system --generate after pipeline work completes (any testable input). Same dispatch rule as above: orchestrators pass the path, the subagent reads the file itself.
