Vom Sample behauptet, vom Vertrag gemessen
176–200 von 568, gemessen von veröffentlichten Samples.
-
gemSample-Vertragruby · linux/x64mustermann@4.0.0
AngenommenMustermann pattern matching always requires full string matches, and string interpolation of pattern objects safely preserves named parameter boundaries without altering AST capture names.
GemessenMustermann patterns anchored to string boundaries return nil on subpaths when using match or params, but peek_params performs unanchored prefix matching and returns both extracted params and the consumed character offset for stepwise sub-routing.
-
golangSample-Vertraggo · linux/x64github.com/go-chi/chi/v5@v5.3.1
Angenommenmiddleware.Timeout enforces a hard wall-clock timeout by asynchronously aborting the handler and returning 504 Gateway Timeout even if the handler blocks or writes data.
GemessenWhen a handler cooperatively returns upon ctx.Done() without writing to ResponseWriter, middleware.Timeout writes HTTP 504 StatusGatewayTimeout with an empty body.
-
gemSample-Vertragruby · linux/x64set@1.1.3
AngenommenSet#<=> provides a total ordering across any sets so arrays of sets can be sorted with Array#sort.
GemessenSet#<=> returns nil when neither set is a subset of the other, which causes Array#sort on incomparable sets to raise ArgumentError.
-
pypiSample-Vertragpython · linux/x64six@1.17.0
Angenommensix.b encodes any text to bytes and accepts existing bytes idempotently, six.u coerces bytes to str, and six.byte2int coerces integer inputs while defaulting empty bytes to zero
Gemessensix.b strictly encodes strings using latin-1 raising UnicodeEncodeError on code points above 255 and AttributeError on existing bytes rather than coercing via UTF-8 or acting idempotently
-
pypiSample-Vertragpython · linux/x64six@1.17.0
AngenommenAccessing moved attributes on six.moves or its classes returns the descriptor or resolved object identically without mutating class state, and six.remove_move cleans up import hooks alongside attribute access
GemessenAccessing an attribute on six.moves or its lazy namespaces resolves the target, caches it in the instance dictionary, and deletes the lazy descriptor from the class dictionary, making class-level attribute access fail with AttributeError
-
golangSample-Vertraggo · linux/x64go.opentelemetry.io/otel/sdk@v1.45.0
Angenommenresource.Merge returns a nil Resource pointer when encountering an ErrSchemaURLConflict between resources with different schema URLs.
Gemessenresource.Merge with conflicting non-empty schema URLs returns a non-nil Resource with SchemaURL set to empty string alongside ErrSchemaURLConflict while merging attributes
-
golangSample-Vertraggo · linux/x64go.opentelemetry.io/otel@v1.28.0
AngenommenExtracting from a request with multiple traceparent headers ignores them completely as mandated by the W3C Trace Context specification.
GemessenExtracting from a HeaderCarrier with two traceparent headers yields the SpanContext of the first header rather than an invalid, empty context.
-
pypiSample-Vertragpython · linux/x64six@1.17.0
Angenommensix.reraise(tp, value, tb) accepts a string message as value and instantiates tp(value) like Python 2's raise statement, and six.raise_from(exc, None) retains implicit exception context.
Gemessensix.reraise requires value to be an exception instance or None and raises AttributeError when passed a string message, unlike Python 2 raise syntax
-
pypiSample-Vertragpython · linux/x64six@1.17.0
Angenommensix.int2byte raises standard built-in ValueError or TypeError for invalid integer inputs like Python 2 chr() or Python 3 bytes constructor, and six.remove_move raises KeyError for nonexistent moves
Gemessensix.int2byte raises struct.error rather than built-in ValueError or TypeError when passed out-of-range integers or non-integer types because it is implemented via struct.Struct.pack in Python 3
-
pypiSample-Vertragpython · linux/x64pydantic@2.13.4
AngenommenPydantic models validate and coerce all field defaults against annotated types and constraints during default instantiation.
GemessenLeaving validate_default unset defaults to False: uncoerced string defaults remain raw strings and constraint-violating defaults are assigned directly without validation errors.
-
pypiSample-Vertragpython · linux/x64pydantic@2.13.4
AngenommenSerializing a Pydantic model to JSON and parsing it back with model_validate_json preserves the original plaintext secret or raises a validation error.
Gemessenmodel_dump_json masks SecretStr and SecretBytes to asterisks, and subsequent model_validate_json silently parses the mask string as the new secret value instead of preserving the secret or raising an error.
-
golangSample-Vertraggo · linux/x64go.opentelemetry.io/otel/sdk@v1.45.0
AngenommenCapacity limits on a span apply a uniform dropping strategy, meaning both attributes and events would drop the newest entries or both would drop the oldest entries.
GemessenWhen AttributeCountLimit is 3 and five attributes are added in order a0…a4, span.Attributes() contains exactly the first three (a0, a1, a2), not the last three — new arrivals are silently dropped, not old ones.
-
pypiSample-Vertragpython · linux/x64pydantic@2.13.4
AngenommenPassing a set of field names like {'members': {'secret'}} to model_dump(exclude=...) excludes that field from each nested model in a sequence.
GemessenPassing a bare field set like {'members': {'secret'}} to model_dump(exclude=...) silently leaves secrets present in nested sequence elements because collection keys represent item indices rather than attribute names.
-
pubSample-Vertragdart · linux/x64args@2.7.0
AngenommenArgResults returns an isolated or unmodifiable list for multi-option default values on each parse rather than sharing a mutable reference to the parser's internal default list.
GemessenArgResults.multiOption returns the exact mutable defaultsTo list instance stored in Option without copying, causing identical() to return true across distinct parse calls and leaking in-place mutations into subsequent parses.
-
npmSample-Vertragnode · linux/x64react@18.3.1
AngenommenstartTransition defers callback execution asynchronously or returns a Promise that keeps async continuations within the transition context.
GemessenstartTransition executes its callback synchronously on the calling thread, returns undefined rather than a Promise, and resets ReactCurrentBatchConfig.transition to null immediately before returning so asynchronous continuations run outside the transition context.
-
golangSample-Vertraggo · linux/x64go.opentelemetry.io/otel/sdk@v1.24.0
AngenommenParentBased(NeverSample()) disables span sampling across all spans created by the TracerProvider
GemessenParentBased(NeverSample()) samples and exports child spans when the context contains a sampled remote parent, because ParentBased delegates sampled remote parents to AlwaysSample() by default rather than the configured root sampler.
-
golangSample-Vertraggo · linux/x64go.opentelemetry.io/otel/sdk@v1.37.0
AngenommenAlwaysSample().Description() returns "AlwaysSample" and NeverSample().Description() returns "NeverSample" matching their Go constructor identifiers
GemessenAlwaysSample().Description() returns "AlwaysOnSampler" and NeverSample().Description() returns "AlwaysOffSampler" using OpenTelemetry specification names rather than Go constructor names
-
pypiSample-Vertragpython · linux/x64httpx@0.28.1
AngenommenSubclassing Auth to inspect streaming request bodies or handle 401 challenge retries can be done by accessing request.content directly or yielding requests without explicit body buffering flags, and Authorization headers are automatically retained across all followed redirects.
GemessenAccessing request.content on streaming requests inside auth_flow raises RequestNotRead unless requires_request_body is set to True
-
pypiSample-Vertragpython · linux/x64httpx@0.28.1
AngenommenConverting Headers and QueryParams to standard Python dictionaries preserves all multi-value items or maps duplicate keys to lists.
GemessenConverting Headers to a standard dictionary collapses duplicate header keys into a single comma-delimited string rather than preserving discrete wire occurrences or lists.
-
pypiSample-Vertragpython · linux/x64httpx@0.28.1
AngenommenJoining a relative path to an httpx.URL always appends to the full path prefix of the base URL
Gemessenhttpx.URL.join on a base path lacking a trailing slash replaces the final path segment rather than appending to it
-
npmSample-Vertragnode · linux/x64@babel/preset-env@7.26.0
AngenommenisPluginRequired accepts shorthand target versions such as chrome '80' matching Babel configuration presets, and returns false when targets is empty since no target platforms require compilation.
GemessenisPluginRequired throws a semver validation error when targets specifies a non-triplet version like '80' while support data allows '79', returns false when target version 80.0.0 meets support version 79, and returns true when targets is empty or includes unspecified environments.
-
pypiSample-Vertragpython · linux/x64httpx@0.28.1
Angenommenhttpx.InvalidURL inherits from httpx.HTTPError and catching httpx.HTTPError catches URL formatting errors
Gemessenhttpx.InvalidURL inherits directly from builtins.Exception rather than httpx.HTTPError or httpx.RequestError, so catching httpx.HTTPError fails to catch URL validation failures.
-
npmSample-Vertragnode · linux/x64express@4.21.0
Angenommenres.format requires handlers to set their own Content-Type header and falls back to a 200 response or uncaught exception when the Accept header is unmatched
Gemessenres.format automatically sets the Vary: Accept header and pre-populates Content-Type matching the negotiated format before executing the handler
-
npmSample-Vertragnode · linux/x64express@4.21.2
Angenommenrouter.param callbacks defined on a child router with mergeParams: true execute for all named parameters present in req.params during route handling.
GemessenExpress router.param callbacks only execute when the parameter placeholder is declared in the matching route's own path pattern, ignoring inherited parameters populated on req.params by mergeParams: true.
-
npmSample-Vertragnode · linux/x64express@5.2.1
AngenommenA good model would confidently expect that query parameters configured or named to represent collections will always parse as an array if present, or that ?id[]=1 syntax forces an array type.
Gemessenreq.query.id parses ?id=1 as the string '1', not an array.
Wie Sie jede Zeile hier prüfen
Öffnen Sie das Sample, lesen Sie seinen Contract, führen Sie ihn aus. Der Contract ist der eigene Test des Samples: Er läuft ohne Netz in einem gepinnten Container, und die signierte Quittung dieses Laufs ist das, was das Netzwerk speichert. Nichts hier hängt davon ab, wie wir eine Bibliothek lesen — nur davon, was sie getan hat.
Einige veröffentlichte Beispiele stehen nicht auf dieser Seite. Ihr Vertrag ist bestanden und das Beispiel ist live — aber keine Zeile dieses Vertrags liest sich als Satz. Eine Zusicherung wie expect(x).toBe(1) sagt neben der Annahme, die sie prüft, niemandem etwas. Sie bleiben lieber draußen, als als Beleg zu erscheinen, den niemand lesen kann.
