-
composerSample-Vertragphp · linux/x64symfony/console@v8.1.4
AngenommenQuestionHelper applies configured Question normalizers to default values in non-interactive execution before validating and returning the response.
GemessenQuestionHelper::ask() in non-interactive mode completely bypasses Question::setNormalizer(), returning the unnormalized default value and passing the unnormalized type directly to the validator.
-
composerSample-Vertragphp · linux/x64symfony/console@7.4.16
AngenommenA model expects that destroying StreamOutput closes its underlying stream resource, ConsoleOutput opens fresh stream handles per instance, OutputFormatter resets style tags between format calls, and ProgressBar writes output to STDOUT.
GemessenStreamOutput does not close its underlying stream resource when destroyed, leaving the file descriptor open unless explicitly closed with fclose by the caller
-
composerSample-Vertragphp · linux/x64symfony/console@8.1.4
AngenommenSerializing an ArrayInput instance to a CLI string with __toString() produces argument tokens that preserve boolean flag states and option values when round-tripped through StringInput.
GemessenArrayInput::__toString() serializes a boolean true flag as '--flag=1', which throws RuntimeException when rebound to a VALUE_NONE option, and serializes a boolean false flag as '--flag', which inverts the flag to true when reparsed.
-
composerSample-Vertragphp · linux/x64symfony/console@7.2.1
AngenommenDeclaring a protected static $defaultName property on a Command subclass sets the command name and description and allows registering it with Application::add().
GemessenIn Symfony Console 7, Command::getDefaultName() returns null for classes defining static $defaultName, leaving the command name null and causing Application::add() to throw LogicException unless configured via the #[AsCommand] attribute.
-
golangSample-Vertraggo · linux/x64sigs.k8s.io/yaml@v1.6.0
AngenommenUnmarshaling YAML with type mismatches returns a yaml.TypeError, non-pointer destinations return an InvalidUnmarshalError, and UnmarshalStrict returns uniform YAML unmarshal errors for all schema violations.
GemessenType mismatch in YAML unmarshaling returns a wrapped *json.UnmarshalTypeError with prefix 'error unmarshaling JSON' and does not match yaml.TypeError
-
hexSample-Vertragelixir · linux/x64nimble_options@1.1.1
AngenommenA custom type callback is expected to return an error tuple and still be reported as {:error, ValidationError}; anything else should do the same.
Gemessenassert NimbleOptions.validate([port: :bad], custom_schema()) converts {:error, message} from the callback into a NimbleOptions.ValidationError whose message is prefixed with the library error field
-
hexSample-Vertragelixir · linux/x64decimal@3.1.1
AngenommenDecimal.new/1 and Decimal.parse/1 parse any decimal string containing up to the default decimal128 context precision of 34 significant digits regardless of leading zeros.
Gemessenassert Decimal.new parses 34 significant digits with leading zero without exceeding max_digits
-
golangSample-Vertraggo · linux/x64github.com/go-chi/chi/v5@v5.3.1
AngenommenCalling ClientIPFromXFF with no arguments extracts the originating client IP from the leftmost entry in X-Forwarded-For and updates RemoteAddr like RealIP.
Gemessenassert ClientIPFromXFF with unset trusted prefixes returns the rightmost XFF hop rather than the leftmost client IP
-
golangSample-Vertraggo · linux/x64github.com/go-chi/chi/v5@v5.3.1
AngenommenRegistering middleware.URLFormat and middleware.StripSlashes in either order yields the same route match behavior for /item.json/.
GemessenWhen middleware.URLFormat is registered before middleware.StripSlashes and only GET /item exists, GET /item.json/ returns 404.
-
golangSample-Vertraggo · linux/x64sigs.k8s.io/yaml@v1.4.0
Angenommensigs.k8s.io/yaml.Unmarshal preserves exact 64-bit integer values when decoding YAML into untyped maps or interface{} fields without explicit decoder options.
Gemessenassert default Unmarshal silently truncates integers above 2^53 into float64 whereas JSONOpt UseNumber preserves exact int64 values as json.Number
-
golangSample-Vertraggo · linux/x64encoding/json@v1.26.5
AngenommenA JSON encoder serializes string values using standard RFC 8259 character escaping, preserving literal <, >, and & characters unless HTML escaping is explicitly enabled.
Gemessenassert json.NewEncoder with default settings escapes <, >, and & into \u003c, \u003e, and \u0026
-
golangSample-Vertraggo · linux/x64sigs.k8s.io/yaml@v1.4.0
AngenommenA caller expects unknown YAML keys to be rejected by default when decoding into a typed struct.
Gemessenassert Unmarshal succeeds when decoding `name: main unknown: value` into `decodeTarget` without options
-
golangSample-Vertraggo · linux/x64encoding/json@go1.26.5
AngenommenUsing Decoder.UseNumber causes every decoded number to be produced as json.Number, even when decoding into a concrete numeric struct field.
Gemessenassert that decoding `{"count": 7, "wildcard": 7}` with Decoder.UseNumber into struct `{Count int; Wildcard any}` yields `Count` as an `int` and `Wildcard` as `json.Number`
-
golangSample-Vertraggo · linux/x64net/http@go1.26.5
AngenommenA caller using a default http.Client should see the same payload bytes and encoding metadata that the server put on the response.
GemessenWhen a server writes a gzip-compressed body, a default http.Client request must return plain text bytes, not gzip bytes.
-
golangSample-Vertraggo · linux/x64net/http@go1.26.5
AngenommenA POST request that receives a 303 See Other keeps its method and body through automatic redirect following.
GemessenA default client must follow `StatusSeeOther` (`303`) by issuing the next request as `GET`, not as the original method.
-
golangSample-Vertraggo · linux/x64net/http@go1.26.5
AngenommenA method token in a ServeMux pattern, such as `GET /resource`, is just part of the path and does not affect routing.
GemessenRegistering `HandleFunc("GET /resource", ...)` and `HandleFunc("POST /resource", ...)` must allow GET and POST only, while a PUT request to `/resource` must fail with 405.
-
golangSample-Vertraggo · linux/x64encoding/json@v1.26.5
Angenommenjson.Marshal encodes fixed-size byte arrays [N]byte as Base64 strings and json.Unmarshal decodes Base64 strings into byte arrays.
Gemessenassert json.Marshal encodes fixed-size byte array [N]byte as a JSON numeric array instead of a base64 string
-
golangSample-Vertraggo · linux/x64encoding/json@go1.26.5
AngenommenA field is omitted only when its value is reflect-empty, so a non-empty struct value must always be serialized unless `omitempty` is false.
Gemessenassert json.Marshal with tag `field,omitzero` omits a non-empty struct when its IsZero() method returns true
-
golangSample-Vertraggo · linux/x64encoding/json@v1.26.5
AngenommenA caller can treat json.Encoder.Encode as json.Marshal followed by Write, so the output bytes are exactly the JSON value.
Gemessenassert that json.NewEncoder(&buf).Encode(v) appends a trailing \n byte to the encoded output
-
pypiSample-Vertragpython · linux/x64httpx2@2.10.0
AngenommenPassing query parameters via the params argument merges them with query parameters already present in the target URL.
Gemessenassert passing params to Request('GET', 'https://example.com/search?q=python', params={'page': '2'}) overwrites the URL query to 'page=2', discarding 'q=python'
-
composerSample-Vertragphp · linux/x64symfony/console@7.4.16
AngenommenA competent developer or model expects that during the execution of a parent command, the Application's active running command context is preserved across sub-command invocations, ensuring that error rendering retains the parent command's synopsis throughout its lifecycle.
GemessenApplication doRun resets runningCommand to null upon sub-command completion instead of restoring the parent command
-
composerSample-Vertragphp · linux/x64guzzlehttp/guzzle@8.0.2
AngenommenPassing a stream or resource sink to a request that follows redirects writes only the final destination response body into the sink.
Gemessenassert a stream sink passed during redirected requests accumulates both intermediate redirect bodies and final response body instead of only the destination body
-
npmSample-Vertragnode · linux/x64vitest@4.1.10
AngenommenmockReset clears call records and replaces the mock implementation with an empty function returning undefined like Jest, rather than reverting to the initial implementation while keeping the spy active
Gemessenassert mockReset on vi.spyOn reverts to initial method implementation instead of undefined while continuing to intercept and record calls
-
cargoSample-Vertragrust · linux/x64winnow@1.0.4
AngenommenWhen an alt combinator fails on invalid input after partially matching an alternative, ContextError preserves the error details and byte offset from whichever branch parsed deepest.
Gemessenassert alt with ContextError discards a partial match in an earlier branch and returns the error and offset of the last evaluated branch, while cut_err prevents backtrack and preserves the deep failure site
-
composerSample-Vertragphp · linux/x64symfony/console@8.1.4
AngenommenUnrecognized CLI options throw InvalidOptionException and missing required arguments throw MissingInputException.
GemessenArgvInput with an unknown option throws RuntimeException rather than InvalidOptionException or InvalidArgumentException
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.
