126–150 sur 568, mesurés par des échantillons publiés.
-
pubContrat d'échantillondart · linux/x64json_annotation@4.9.0
On croitA model expects JsonSerializable.fromJson to accept camelCase Dart option names, unknownEnumValue to serve as a fallback when an enum field is null, and disallowNullValues to reject missing keys.
MesuréJsonSerializable.fromJson enforces snake_case option keys and disallowUnrecognizedKeys, throwing a CheckedFromJsonException with badKey true on camelCase Dart property names
-
golangContrat d'échantillongo · linux/x64github.com/goccy/go-yaml@v1.19.2
On croityaml.Unmarshal silently accepts duplicate mapping keys and overwrites earlier occurrences with later ones.
Mesuréassert yaml.Unmarshal rejects duplicate mapping keys with a SyntaxError by default, leaving destination values empty
-
pypiContrat d'échantillonpython · linux/x64cffi@2.0.0
On croitCalling ffi.string with maxlen reads the full byte length regardless of null bytes, and ffi.buffer on a pointer defaults to the full allocated buffer length.
MesuréCalling ffi.string(cdata, maxlen) truncates at the first null byte rather than reading maxlen bytes, while ffi.unpack extracts the exact byte count across embedded nulls.
-
pubContrat d'échantillondart · linux/x64http@1.6.0
On croitTop-level HTTP convenience functions executed inside runWithClient reuse a shared ambient client instance without closing it after each request.
MesuréTop-level HTTP convenience functions inside runWithClient instantiate a client via the client factory and close it upon completion, causing subsequent requests on a singleton client factory to fail with ClientException.
-
npmContrat d'échantillonnode · linux/x64typescript@5.9.3
On croitTypeScript automatically elides type-only named imports and unused value imports during ECMAScript emit regardless of whether type keywords or verbatimModuleSyntax are configured.
MesuréWhen compilerOptions.verbatimModuleSyntax is enabled, importing a type without the type modifier fails type-checking with TS1484, and re-exporting a type without export type fails with TS1205, whereas type-only imports and inline type specifiers compile cleanly and are elided during emit.
-
npmContrat d'échantillonnode · linux/x64vitest@3.2.7
On croitmergeConfig replaces array options like test.include and test.reporters with override values and supports function config factories.
MesurémergeConfig concatenates array options like test.include, test.exclude, and test.reporters rather than replacing them, appending override test filters to base patterns.
-
pubContrat d'échantillondart · linux/x64convert@3.1.2
On croitCodePage.encode and CodePage.decode silently replace unmapped characters or undefined bytes with fallback tokens rather than throwing FormatException.
MesuréCodePage.encode throws FormatException on unmapped characters unless configured with an in-range invalidCharacter byte, and CodePage.decode throws FormatException on undefined byte entries unless allowInvalid is set to true.
-
npmContrat d'échantillonnode · linux/x64browserslist@4.28.8
On croitpassing custom usage statistics via opts.stats causes standard popularity queries like '> 10%' to automatically evaluate against the provided custom statistics
Mesurébrowserslist('> 10% in my stats') throws a BrowserslistError when opts.stats is omitted
-
golangContrat d'échantillongo · linux/x64github.com/go-playground/validator/v10@v10.30.3
On croitTagging a non-pointer struct field with validate:"required" causes validator.New().Struct() to reject an uninitialized zero-value struct.
Mesurévalidator.New() ignores validate:"required" on non-pointer struct fields and returns nil for zero-value structs, while validator.WithRequiredStructEnabled() causes validation to fail with a required tag error on the struct field.
-
pubContrat d'échantillondart · linux/x64shelf@1.4.2
On croitA mounted sub-router configured with a custom notFoundHandler only handles its own 404s when no other parent routes match, allowing sibling or fallback routes in the parent Router to catch unhandled paths.
MesuréA parent Router falls through unmatched sub-paths to subsequent sibling routes when the mounted sub-router uses the default notFoundHandler, but halts and returns 404 when configured with a custom notFoundHandler.
-
golangContrat d'échantillongo · linux/x64github.com/spf13/pflag@v1.0.10
On croitEnabling ParseErrorsWhitelist.UnknownFlags allows unrecognized flags to pass through without error while preserving all subsequent positional arguments in FlagSet.Args().
MesuréWhen ParseErrorsWhitelist.UnknownFlags is true, FlagSet.Parse on unknown flags without an equals sign silently consumes the following non-flag argument as the flag value, leaving Args empty rather than preserving the positional argument.
-
golangContrat d'échantillongo 1.26 · linux/x64google.golang.org/grpc@v1.83.0
On croitA client can receive responses larger than 4MB without additional configuration because the default 4MB limit applies only to server request payloads, or by setting grpc.MaxCallSendMsgSize on the client.
MesuréWhen a gRPC server returns a 5MB payload to a client with default options, the server transmits it without error but the client fails to decode the response with status code ResourceExhausted because the default client-side receive limit is 4MB.
-
pubContrat d'échantillondart · linux/x64shelf@1.4.2
On croitA shelf Cascade cascades to subsequent handlers on any 4xx or 5xx client or server error response by default.
MesuréCascade defaults to cascading only on 404 and 405 status codes, requiring explicit statusCodes or shouldCascade configuration to cascade past 400 Bad Request, 401 Unauthorized, or 500 Internal Server Error responses.
-
golangContrat d'échantillongo · linux/x64go.uber.org/zap@v1.27.0
On croitzap.Config.Build automatically resolves unregistered URI schemes to file paths or creates default sink wrappers for custom protocol schemes
Mesurézap.Config.Build fails with a 'no sink found for scheme' error when OutputPaths contains a URI scheme that has not been registered via zap.RegisterSink.
-
golangContrat d'échantillongo 1.26 · linux/x64github.com/gin-gonic/gin@v1.12.0
On croitgin.Context implements context.Context so it automatically delegates Value, Deadline, and Done to the underlying http.Request context without extra configuration.
MesuréBy default gin.Engine has ContextWithFallback disabled, causing gin.Context to return nil for all http.Request context values and ignore request deadlines and cancellation.
-
pypiContrat d'échantillonpython · linux/x64pillow@10.4.0
On croitImage.open checks image size limits only during pixel rasterization and raises a generic MemoryError rather than DecompressionBombError when pixels exceed Image.MAX_IMAGE_PIXELS.
MesuréImage.open eagerly raises PIL.Image.DecompressionBombError during header parsing when total pixels exceed twice Image.MAX_IMAGE_PIXELS without allocating pixel memory.
-
pypiContrat d'échantillonpython · linux/x64anyio@4.13.0
On croitCancelling a task waiting on anyio.to_thread.run_sync cancels immediately without waiting for the synchronous thread, and setting abandon_on_cancel=True keeps worker thread concurrency strictly bounded by the CapacityLimiter.
MesuréWith abandon_on_cancel=False, cancelling the calling scope blocks until the worker thread finishes running, whereas abandon_on_cancel=True exits the scope immediately while releasing the CapacityLimiter before the synchronous thread finishes.
-
hexContrat d'échantillonelixir · linux/x64decimal@3.1.1
On croitSetting a Decimal context configuration applies across the application or automatically propagates to spawned child processes and tasks.
MesuréDecimal context is scoped to the calling process dictionary and is not inherited by spawned child tasks
-
npmContrat d'échantillonnode · linux/x64vue@3.5.41
On croitIn production mode (NODE_ENV=production), an unhandled error thrown during Vue SSR component setup or rendering causes renderToString() to reject with the error.
MesuréIn production mode, unhandled errors in component setup or rendering are suppressed and logged to console by default, causing renderToString to resolve with partial markup unless app.config.throwUnhandledErrorInProduction is set to true.
-
pypiContrat d'échantillonpython · linux/x64tenacity@9.1.4
On croitretry_unless_exception_type retries functions that raise unexpected exceptions while allowing successful returns to exit immediately without retrying.
Mesuréretry_unless_exception_type treats successful return values as retryable states, retrying until stop exhaustion and raising RetryError with a successful last_attempt Future.
-
gemContrat d'échantillonruby · linux/x64minitest@6.0.6
On croitCalling parallelize_me! inside a test class always enables parallel test execution across worker threads or raises an error if threads cannot be allocated
MesuréWhen MT_CPU is 1 or less at load time, Minitest.parallel_executor is nil, causing parallelize_me! to leave test class run_order as :random without including Minitest::Parallel::Test, running tests synchronously on the main thread
-
npmContrat d'échantillonnode · linux/x64jose@6.2.9
On croitSetting maxTokenAge only limits allowable token age when an iat claim is present, falling back to exp expiration checking when iat is omitted.
MesuréjwtVerify with maxTokenAge configured rejects tokens lacking an iat claim with JWTClaimValidationFailed and reason 'missing' rather than falling back to exp validation.
-
npmContrat d'échantillonnode · linux/x64rollup@4.34.8
On croitA bare import with no specifiers, such as import './polyfill.js', is always retained during tree-shaking because it declares an intentional side effect with no unused bindings to eliminate.
MesuréSetting treeshake: { moduleSideEffects: false } causes Rollup to strip bare side-effect imports that have no consumed exports, whereas treeshake: { moduleSideEffects: 'no-external' } retains internal side-effect imports and strips unused external ones.
-
golangContrat d'échantillongo · linux/x64github.com/google/go-cmp@v0.7.0
On croitPassing multiple cmp.Transformer or cmp.Comparer options for the same underlying type automatically evaluates them in order or restricts them to their intended struct context.
Mesuréassert cmp.Diff panics with ambiguous set of applicable options when multiple transformers or comparers target the same type without path filters
-
pypiContrat d'échantillonpython · linux/x64pyarrow@25.0.1
On croitpyarrow.csv.read_csv parses tokens defined in null_values as null values across all columns regardless of inferred column data type.
MesuréCSV columns inferred as strings preserve tokens matching null_values as literal strings unless strings_can_be_null is explicitly set to True, whereas numeric columns convert them to nulls by default.
Comment vérifier n'importe quelle ligne
Ouvrez l'échantillon, lisez son contract, exécutez-le. Le contract est le test propre à l'échantillon : il tourne hors réseau dans un conteneur épinglé, et c'est le reçu signé de cette exécution que le réseau conserve. Rien ici ne repose sur notre lecture d'une bibliothèque, seulement sur ce qu'elle a fait.
Certains échantillons publiés ne figurent pas sur cette page. Leur contrat est passé et l'échantillon est en ligne, mais aucune ligne de ce contrat ne se lit comme une phrase. Une assertion comme expect(x).toBe(1), placée à côté de la croyance qu'elle vérifie, n'apprend rien au lecteur. Nous préférons les omettre plutôt que publier une preuve que personne ne peut lire.
