Project type: !

find . -maxdepth 1 ( -name 'pyproject.toml' -o -name 'package.json' -o -name 'Cargo.toml' -o -name 'go.mod' )

Test directories: !

find . -maxdepth 2 -type d ( -path '/tests/unit' -o -path '/test/unit' -o -path '*/tests/unit' )

Last test run: !

find .pytest_cache/v/cache -maxdepth 1 -name 'lastfailed'

Parameters

$1

Optional path or test pattern

--watch

Enable watch mode for continuous feedback

--affected

Only run tests for files changed since last commit

Your task

Delegate this task to the

test-runner

agent.

Use the Task tool with

subagent_type: test-runner

to run fast unit tests only. Pass all the context gathered above and specify

Tier 1 (unit tests)

execution.

The test-runner agent should:

Run unit tests only

(target < 30s):

Exclude slow, integration, and E2E tests

Use appropriate markers/flags for the framework:

pytest:

-m "not slow and not integration and not e2e"

vitest:

--exclude="/e2e/" --exclude="/integration/"

cargo:

--lib

go:

-short

Apply options

:

If

--watch

Enable continuous test execution

If

--affected

Only test changed files

Fail fast

Stop on first failure (

-x

or

--bail

)

Provide concise output

:

Unit Tests: [PASS|FAIL]

Passed: X | Failed: Y | Duration: Zs

Failures (if any):

- test_name: Brief error (file:line)

Rerun failed: [command]

Post-action guidance

:

If all pass: Ready for continued development

If failures: Fix before proceeding (fail fast principle)

If > 30s: Suggest

/test:consult

for optimization

Provide the agent with:

All context from the section above

The parsed parameters

Explicit instruction

Tier 1 only, skip slow tests The agent has expertise in: Tiered test execution Fast feedback loops Test isolation and parallelization
