Write correct synchronous Gomega assertions — Expect/Ω notation, the To/NotTo/ToNot/Should/ShouldNot equivalences, the multi-return error idiom, Succeed vs HaveOccurred, the .Error() chaining form, annotating assertions (format-string and func()string), tuning failure output via the format subpackage…

Polling assertions in Gomega — Eventually (poll until it passes) and Consistently (must keep passing), the func(g Gomega) callback idiom, WithTimeout/WithPolling/Within/ProbeEvery, WithContext and Ginkgo SpecContext, StopTrying/TryAgainAfter bail-outs, MustPassRepeatedly, and default-interval tuning. Use when an…

Build compound Gomega assertions by combining matchers — And/SatisfyAll (all pass), Or/SatisfyAny (any pass), Not (negate), WithTransform to map the actual before matching, Satisfy for an ad-hoc predicate, HaveValue to dereference pointers/interfaces, HaveField for struct fields and method results, HaveEach for every…

Writing your own Gomega matchers — the GomegaMatcher interface (Match/FailureMessage/NegatedFailureMessage), gcustom.MakeMatcher with message templates and template data, the format package helpers (format.Message/format.Object), MatchMayChangeInTheFuture and StopTrying for Eventually/Consistently, and how to test and…

Testing streaming io buffers with gbytes — gbytes.NewBuffer() (an io.Writer also returned by gexec sessions), the Say(regexp) matcher that forward-scans from a moving read cursor, the canonical Eventually(buffer).Should(Say(...)) streaming pattern, sequential cursor-advancing Say calls, Contents()…

Testing external processes with gexec — compile binaries with Build/BuildWithEnvironment/BuildIn and CleanupBuildArtifacts, start them with Start returning a Session, await exit with the Exit matcher (Eventually(session).Should(Exit(0))), Wait/ExitCode, signal via Kill/Terminate/Interrupt/Signal and package-level…

The ghttp test HTTP server for testing HTTP clients — NewServer/NewTLSServer, AppendHandlers, the Verify assertions (VerifyRequest/VerifyHeader/VerifyHeaderKV/VerifyJSON/VerifyForm/VerifyBasicAuth/VerifyContentType/VerifyBody), RespondWith/RespondWithJSONEncoded(Ptr), CombineHandlers, RouteToHandler for unordered…

Benchmark and measure Go code with gmeasure — an Experiment groups named Measurements, recorded via RecordValue/RecordDuration/MeasureDuration or repeated Sample/SampleValue/SampleDuration with SamplingConfig, timed inline with a Stopwatch, summarized through GetStats/Stats (StatMin/Max/Mean/Median/StdDev…

Deep, partial matching of nested structs, slices, maps, and pointers with gstruct — MatchAllFields/MatchFields/Fields, MatchAllElements/MatchElements/Elements (idFn), MatchAllKeys/MatchKeys/Keys, PointTo, and the IgnoreExtras/IgnoreMissing/IgnoreUnexportedExtras/AllowDuplicates options, plus Ignore()/Reject().

The complete catalog of Gomega's built-in matchers, grouped by category — equivalence (Equal/BeEquivalentTo/BeComparableTo/BeIdenticalTo/BeAssignableToTypeOf), presence (BeNil/BeZero/BeEmpty), truthiness (BeTrue/BeFalse/BeTrueBecause), errors (HaveOccurred/Succeed/MatchError), channels (Receive/BeClosed/BeSent)…

The Gomega mental model for writing assertions in Go — the Expect/Ω notation, matchers-are-values, the multi-return error idiom, synchronous vs asynchronous (Eventually/Consistently) assertions, and a map of the whole library including the gstruct/ghttp/gexec/gbytes/gleak/gmeasure sub-libraries. Use this first when…
