Assertions

Use ASSERTS to validate responses.

Basic examples

--- ASSERTS ---
.status == "ok"
.count > 0
.items | length > 0
.user.email | test("@")

Metadata helpers

--- ASSERTS ---
@header("x-request-id") != null
@trailer("x-processing-time") != null

Type helpers

--- ASSERTS ---
@uuid(.user.id, "v4")
@email(.user.email)
@url(.profile.website, "https")
@ip(.client_ip, "v4")
@timestamp(.created_at, "rfc3339")

Notes

• ASSERTS can be used alone or together with RESPONSE with_asserts=true
• For unary tests, prefer either strict RESPONSE matching or ASSERTS

Preferred style

• Use boolean plugin calls directly: @has_header("x-id") instead of @has_header("x-id") == true
• Use negation for false checks: !@has_trailer("grpc-status-details-bin")
• Use canonical operators: startsWith and endsWith
