gemSample-Vertragruby · linux/x64sorbet-runtime@0.6.13427
AngenommenT::Enum instances compare equal to their serialized string or symbol values, and from_serialized returns nil for unmatched strings instead of raising KeyError.
Gemessenassert T::Enum instances are not equal to strings or symbols, and that passing a raw string to a T::Enum parameter raises TypeError
-
gemSample-Vertragruby · linux/x64sinatra@4.2.1
AngenommenAn empty PATH_INFO is treated as a normal non-match and should fail with a 404 instead of entering `get('/')`.
Gemessenassert a request with PATH_INFO '' receives status 200 from GET / and returns the same body as PATH_INFO '/'
-
gemSample-Vertragruby · linux/x64sinatra@4.2.1
AngenommenSinatra::IndifferentHash.new({"role" => "admin"}) produces a populated hash where the string and symbol keys both resolve to "admin", matching the same pattern that worked in Sinatra 3
GemessenSinatra::IndifferentHash.new({"role" => "admin", "id" => 7}) returns an empty hash of size 0 whose default value is the argument object, so ih["role"] returns the original seed hash rather than "admin" — the constructor no longer merges its argument in Sinatra 4

gemSample-Vertragruby · linux/x64sinatra@4.2.1
AngenommenA competent developer expects bare query flags `?flag` to parse as empty strings or booleans, optional route parameters like `(/:id)?` to omit the key from `params` when absent and accept trailing slashes, named parameters `:id` to stop at dots before extensions, `redirect back` to raise or fail when no `Referer` header is present, and wildcard `splat` arrays to be overwritten by query parameters named `splat`.
Gemessenassert an omitted optional route parameter in (/:id)? populates params[:id] as nil with params.key?('id') true while trailing slash /users/ returns 404, bare query flags parse as nil rather than empty strings, and named route params capture across dots
-
gemSample-Vertragruby · linux/x64sinatra@4.2.1
AngenommenEach overlapping request to the same Sinatra app instance is isolated from in-flight request mutations.
GemessenTwo in-flight calls to the same Sinatra app can share one class-level state slot, so the first call can observe the second call’s write before it returns.
-
gemSample-Vertragruby · linux/x64sinatra@4.2.1
AngenommenCalling pass inside a matched route handler discards intermediate modifications to the HTTP status code, response headers, cookies, and request params before dispatching to subsequent matching routes.
GemessenCalling pass retains any HTTP status code, response headers, cookies, and params mutations made by the passed route rather than resetting the response state for the fallback handler.
-
gemSample-Vertragruby · linux/x64sinatra@4.2.1
AngenommenCalling halt with a status integer and headers hash sets the HTTP response status code and headers with an empty body.
Gemessenassert halt with status code and hash assigns the hash to the response body and leaves headers unset
-
gemSample-Vertragruby · linux/x64sinatra@4.2.1
AngenommenConfiguring settings with Sinatra's set method replaces existing Hash configurations, stores Proc and lambda values as callable objects on the settings object, and passes form HTTP verb overrides through to DELETE and PUT route handlers by default.
GemessenSinatra::Base.set merges new Hash options into previous Hash settings rather than overwriting them, and evaluates Proc or lambda settings on every property access rather than returning the callable object.
-
gemSample-Vertragruby · linux/x64set@1.1.1
AngenommenA Ruby developer would expect `Set#^` to return a plain `Set` regardless of subclass, so subclass-only behavior hooks are irrelevant.
Gemessenassert Set#^ returns an object of the left operand's subclass when both operands are `Set` subclasses
-
gemSample-Vertragruby · linux/x64set@1.1.1
AngenommenSet#divide with a 2-arity predicate block partitions elements by directly evaluating the block on every pair and grouping each matching pair together, so Set[1,2,3,4].divide { |a,b| (a-b).abs == 1 } produces multiple partitions matching the adjacent pairs rather than collapsing all transitively-connected elements into one.
GemessenSet[1,2,3,4].divide { |a,b| (a-b).abs == 1 } returns a single partition containing all four elements rather than multiple pairwise groups, because the 2-arity form performs a transitive-closure (union-find) over all pairs, merging 1-2, 2-3, and 3-4 into one equivalence class
-
gemSample-Vertragruby · linux/x64set@1.1.1
AngenommenA developer can mutate a `Set` from another task or nested call while iterating it and still get a consistent final result.
GemessenMutating the shared `Set` from another thread while `each` is running must raise `RuntimeError` with `can't add a new key into hash during iteration`.
-
gemSample-Vertragruby · linux/x64set@1.1.1
AngenommenOnce `Set#compare_by_identity` is enabled, a later `Set#replace` keeps identity semantics so membership for value-equal values still requires object identity.
Gemessenassert that calling `replace` with a default-set changes `compare_by_identity?` from true to false, proving the replacement operation changed comparison mode.
-
gemSample-Vertragruby · linux/x64set@1.1.1
AngenommenCalling to_set on an existing Set produces a new Set instance for safe mutation, and calling to_set on a Set subclass preserves the receiver subclass.
Gemessenassert Set#to_set with default arguments returns self instead of a new duplicate set, so mutating the result modifies the original set in-place
-
gemSample-Vertragruby · linux/x64set@1.1.1
AngenommenCalling the spaceship operator <=> or relational comparison operators (<, <=, >, >=) on Sets performs a total ordering comparison based on size or element values so arrays of sets can be sorted, and comparison methods accept any Enumerable.
Gemessenassert Set#<=> returns nil when neither set is a subset of the other rather than ordering by size or elements, causing Array#sort across disjoint sets to raise ArgumentError
-
gemSample-Vertragruby · linux/x64rack-test@2.2.0
AngenommenA `Set-Cookie` header using `Path=/admin` is treated as unrecognized path metadata and should fall back to the request path, so the cookie applies broadly.
Gemessenassert last_response.body on /public does not include sid=abc123
-
gemSample-Vertragruby · linux/x64rack-test@2.2.0
AngenommenRack::Test::Methods exports a METHODS constant of HTTP verbs, standalone session setup requires requiring rack/mock_session, and query parameters cannot be supplied separately from request body params in non-GET requests via env.
Gemessenassert Rack::Test::Methods::METHODS is undefined raising NameError, requiring rack/mock_session raises LoadError with Rack::MockSession aliased to Session, and :query_params in env appends to the URI query string separately from request body payloads
-
gemSample-Vertragruby · linux/x64rack-test@2.2.0
AngenommenReentrant requests dispatched on a Rack::Test::Session preserve last_request and last_response correspondence for the completing outer request.
Gemessenassert reentrant requests dispatched during app execution overwrite last_request with the inner request while last_response reflects the outer response
-
gemSample-Vertragruby · linux/x64rack-test@2.2.0
AngenommenCalling header with a header name already starting with HTTP_ sets the Rack environment key directly, and follow_redirect! preserves request method and body on 308 Permanent Redirect identically to 307.
GemessenRack::Test::Session#header unconditionally prepends HTTP_ to all header names other than CONTENT_TYPE and CONTENT_LENGTH, mangling HTTP_AUTHORIZATION into HTTP_HTTP_AUTHORIZATION, while follow_redirect! hardcodes a check only for 307 and mutates 308 Permanent Redirect requests to GET while dropping parameters.
-
npmSample-Vertragnode · linux/x64happy-dom@20.11.2
AngenommenPassing an HTML string to new Window(html) initializes the document markup, or instantiating new DOMParser() parses HTML strings into a DOM tree.
Gemessennew Window(html) ignores string arguments because the constructor expects an options object, leaving document.body.innerHTML empty and getElementById returning null.
-
gemSample-Vertragruby · linux/x64rack-test@2.2.0
AngenommenCalling restore_state restores all session modifications including headers configured via header or env, and non-GET request verbs like DELETE append parameter hashes to the URI query string.
Gemessenassert restore_state rolls back last_request, last_response, and cookie_jar but leaves mutated session headers in @env to leak into subsequent requests, while non-GET methods encode params into the request body rather than the query string
-
gemSample-Vertragruby · linux/x64rack-test@2.2.0
AngenommenRack::Test::UploadedFile automatically infers the MIME content type from the file extension when the content_type argument is omitted.
GemessenRack::Test::UploadedFile.new with an image file path returns 'text/plain' for content_type rather than 'image/png' when the argument is omitted, because UploadedFile defaults content_type to 'text/plain' without inspecting the filename extension.
-
gemSample-Vertragruby · linux/x64rack-test@2.2.0
AngenommenRack::Test::Methods operates exclusively on a single shared session state, so testing multi-user interactions requires manually creating unmanaged Session instances to avoid leaking cookies and headers.
Gemessenassert with_session switches the active session context with isolated cookies and headers, restoring the prior session upon block exit
-
gemSample-Vertragruby · linux/x64rack-test@2.2.0
AngenommenA `Set-Cookie` flag named `Secure` is treated as case-sensitive in rack-test, so uppercase `Secure` behaves like an unknown token and is ignored.
GemessenA `Set-Cookie` header containing `Secure` in camel case is honored as a secure attribute, so the cookie is not sent on a plain HTTP follow-up request.
-
gemSample-Vertragruby · linux/x64rack-protection@4.0.0
AngenommenSecurity middleware in Rack::Protection sets response security headers with mixed-case names like `X-XSS-Protection` and `X-Content-Type-Options`.
GemessenWhen `text/html` responses pass through XSSHeader, both lowercase keys must be present with values `1; mode=block` and `nosniff`.
-
gemSample-Vertragruby · linux/x64rack-protection@4.2.1
AngenommenInitializing Rack::Protection with default options includes session hijacking defense that clears the session when a client user-agent header changes.
GemessenRack::Protection.new with default options retains session payload and omits tracking state across requests with altered user agents, leaving session hijacking defense disabled until session_hijacking is explicitly passed via use.
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.
