Decorators

Ginkgo decorator reference

Terse lookup. Decorators are passed alongside a node's text/closure: It("...", Serial, Label("slow"), func(){...}). Most attach to containers and/or subjects; some are setup-only or interruptible-only. Decorators on a container apply to all nodes within it; the innermost/most-specific wins when they conflict. Full docs: https://onsi.github.io/ginkgo/#decorator-reference.

Execution / ordering

• Serial (container, subject) — never runs in parallel; Ginkgo runs serial specs last, on process #1. → ginkgo:parallelism.
• Ordered (container only) — child specs run in definition order, never reordered; enables BeforeAll/AfterAll. → ginkgo:ordering-and-flakes.
• ContinueOnFailure (outermost Ordered container only) — a failing spec doesn't skip the rest of the ordered group.
• OncePerOrdered (setup nodes) — makes a BeforeEach/AfterEach run once around an Ordered container (like a BeforeAll) instead of per-spec.
• SpecPriority(int) (container, subject) — hint to run higher-priority specs earlier; use sparingly, not to impose a total order.

Selection / filtering (→ ginkgo:filtering)

• Label("a", "b") (container, subject) — tag specs for --label-filter; labels union down the hierarchy. No &|!,()/" chars.
• Focus (container, subject) — run only focused specs; don't commit it (CI exits non-zero). Constructors: FDescribe, FContext, FIt, FEntry.
• Pending (container, subject) — never run (and never compiled into the run set); no closure needed. Constructors: PDescribe, XDescribe, PIt, XIt, PEntry.
• SemVerConstraint(">= 2.0.0", ...) / ComponentSemVerConstraint("redis", ">= 8.0.0") (container, subject) — run only when --sem-ver-filter satisfies the constraint; children may narrow, not widen.

Flakiness / repetition (→ ginkgo:ordering-and-flakes)

• FlakeAttempts(n) (container, subject) — retry a failing spec up to n times; a later pass marks it flaky, not failed. CLI --flake-attempts=n overrides.
• MustPassRepeatedly(n) (container, subject) — the spec must pass n times in a row to count as passed.

Timeouts / interruption (interruptible nodes — those taking ctx SpecContext; → ginkgo:timeouts-and-async)

• NodeTimeout(d) (subject, setup) — deadline for a single interruptible node.
• SpecTimeout(d) (It only) — deadline for the whole spec (all its nodes combined).
• GracePeriod(d) (subject, setup) — how long Ginkgo waits for an interrupted node to return before leaking it; overrides --grace-period.

Progress reporting (→ ginkgo:debugging-failures)

• PollProgressAfter(d) (subject, setup) — emit a progress report if the node runs longer than d; 0 disables.
• PollProgressInterval(d) (subject, setup) — interval between progress reports once they start.
• SuppressProgressReporting (subject, setup) — silence progress reports for this node.

Wrapping / advanced

• AroundNode(fn) (any node, incl. RunSpecs) — wrap a node's execution; forms a stack on a container applied to every descendant node (unlike BeforeEach, which runs once per spec). Forms: a bare func(), a context transformer func(context.Context) context.Context, or a full wrapper func(ctx, func(context.Context)).

Location / identity (rarely needed by hand)

• Offset(n) (any node) — skip n stack frames when computing the reported code location. Prefer GinkgoHelper() inside helper funcs instead.
• CodeLocation(loc) (any node) — supply a types.CodeLocation explicitly.

Tables

• EntryDescription("format %d") — auto-format Entry descriptions from their parameters; usable table-wide or per-entry. → ginkgo:tables-and-dynamic-specs.
• Entry/It also accept Label, Focus, Pending, FlakeAttempts, etc. — every decorator above works on table entries.

Reporting

• ReportEntryVisibility{Always,FailureOrVerbose,Never} — passed to AddReportEntry to control console emission. → ginkgo:reporting.
