Response Diff, Contract & SLA
Three layered checks for catching regressions without writing assertions case by case.
diff_payloads
Structural diff between two JSON-like payloads.
from je_api_testka import diff_payloads
diff = diff_payloads({"a": 1, "b": 2}, {"a": 1, "b": 3})
diff.changed # {'b': (2, 3)}
diff.added # {}
diff.removed # {}
diff.is_empty # False
Pass ignore_paths to skip volatile fields:
diff_payloads(left, right, ignore_paths=["timestamp", "request_id"])
OpenAPI contract drift
from je_api_testka import diff_openapi_specs
drift = diff_openapi_specs(prev_spec, current_spec)
drift.added_paths
drift.removed_paths
drift.added_operations
drift.removed_operations
drift.schema_changes # dict keyed by 'METHOD /path'
Render the same drift as a markdown changelog:
from je_api_testka.spec import openapi_changelog
print(openapi_changelog(prev_spec, current_spec))
Response time SLA
ResponseSLA carries max_ms and p95_ms thresholds; assert_sla
walks a list of records and raises APIAssertException on breach.
from je_api_testka.diff.sla_check import ResponseSLA, assert_sla
sla = ResponseSLA(max_ms=2000, p95_ms=1500)
assert_sla(records, sla)
