Graysurf Agent Kit GRAPHQL API Testing

GraphQL API Testing

Contract

Prereqs:

• api-gql available on PATH (install via brew install nils-cli).
• jq recommended for pretty-printing/assertions (optional).
• setup/graphql/ exists (or bootstrap from template) with operations, vars, and optional endpoint/jwt presets.

Inputs:

• Operation + variables: setup/graphql/operations/<op>.graphql and setup/graphql/operations/<vars>.json.
• Optional flags/env: --env, --url, --jwt, --config-dir, --no-history (plus GQL_URL, ACCESS_TOKEN, GQL_JWT_VALIDATE_ENABLED, GQL_JWT_VALIDATE_STRICT, GQL_JWT_VALIDATE_LEEWAY_SECONDS).

Outputs:

• Response JSON printed to stdout; errors printed to stderr.
• Optional history file under setup/graphql/.gql_history (gitignored; disabled via --no-history).
• Optional markdown report via api-gql report.

Exit codes:

• 0: request completed successfully
• non-zero: invalid inputs/missing files/http error/client error

Failure modes:

• Invalid GraphQL/variables JSON, or missing config files.
• Auth missing/invalid (JWT) or network/timeout/connection failures.

Goal

Make GraphQL API calls reproducible via:

• setup/graphql/operations/*.graphql + *.json (operations + variables)
• setup/graphql/endpoints.env (+ optional endpoints.local.env)
• setup/graphql/jwts.env (+ optional jwts.local.env)
• setup/graphql/schema.env (+ committed schema SDL, e.g. schema.gql)
• setup/graphql/prompt.md (optional, committed; project context for LLMs: what to test, DB tooling, other test utilities)

TL;DR (fast paths)

Call an existing operation:

api-gql call \
  --env local \
  --jwt default \
  setup/graphql/operations/<operation>.graphql \
  setup/graphql/operations/<variables>.json \
| jq .

Generate a report (includes a replayable ## Command by default):

api-gql report \
  --case "<test case name>" \
  --op setup/graphql/operations/<operation>.graphql \
  --vars setup/graphql/operations/<variables>.json \
  --env local \
  --jwt default \
  --run

Generate a report from a copied api-gql/gql.sh command snippet (no manual rewriting):

api-gql report-from-cmd '<paste an api-gql/gql.sh command snippet>'

Replay the last run (history):

api-gql history --command-only

Resolve committed schema SDL (for LLMs to author new operations):

api-gql schema --config-dir setup/graphql

Flow (decision tree)

• If setup/graphql/prompt.md exists → read it first for project-specific context.
• No setup/graphql/ yet → bootstrap from template:
• cp -R "$AGENT_HOME/skills/tools/testing/graphql-api-testing/assets/scaffold/setup/graphql" setup/
• Have schema but no operation yet → resolve schema (api-gql schema) then add setup/graphql/operations/<name>.graphql + variables json.
• Have operation → run with api-gql call.
• Need a markdown report → use api-gql report --run (or --response).

Notes (defaults)

• History is on by default: setup/graphql/.gql_history (gitignored); one-off disable with --no-history (or GQL_HISTORY_ENABLED=false).
• Reports include ## Command by default; disable with --no-command (or GQL_REPORT_INCLUDE_COMMAND_ENABLED=false).
• Variables: any numeric limit fields (including nested pagination inputs) are normalized to at least GQL_VARS_MIN_LIMIT (default: 5; set GQL_VARS_MIN_LIMIT=0 to disable).
• Prefer --config-dir setup/graphql in automation for deterministic discovery.

CI / E2E (optional)

In CI, use api-gql call as the runner and jq -e as assertions (exit code is the contract):

set -euo pipefail

api-gql call \
  --config-dir setup/graphql \
  --env staging \
  --jwt ci \
  setup/graphql/operations/<operation>.graphql \
  setup/graphql/operations/<variables>.json \
| jq -e '(.errors? | length // 0) == 0 and .data != null' >/dev/null

Notes:

• Many GraphQL servers return HTTP 200 even when .errors is present, so assert it explicitly.
• If you don’t want CI jobs to write history, add --no-history (or set GQL_HISTORY_ENABLED=false).
