method usingAccessor

usingAccessor: <T, TKey extends keyof T, R extends T[TKey] = T[TKey]>(
    obj: T,
    prop: TKey,
    replacement: R
) => R;

• Assigns a value to a property on object with replacement argument. replacement can be any value, including spies, stubs and fakes. This method only works on accessor properties.

call signature

<T, TKey extends keyof T, R extends T[TKey] = T[TKey]>(
    obj: T,
    prop: TKey,
    replacement: R
): R;

• Replaces property on object with replacement argument. Attempts to replace an already replaced value cause an exception. replacement can be any value, including spies, stubs and fakes. This method only works on non-accessor properties, for replacing accessors, use sandbox.replaceGetter() and sandbox.replaceSetter().

property addBehavior

addBehavior: (
    name: string,
    fn: (fake: SinonStub, ...userArgs: any[]) => void
) => void;

• Add a custom behavior. The name will be available as a function on stubs, and the chaining mechanism will be set up for you (e.g. no need to return anything from your function, its return value will be ignored). The fn will be passed the fake instance as its first argument, and then the user's arguments.

  Parameter spies

method expose

expose: (obj: any, options?: Partial<SinonExposeOptions>) => void;

• Exposes assertions into another object, to better integrate with the test framework. For instance, JsTestDriver uses global assertions, and to make Sinon.JS assertions appear alongside them, you can do.

  Example 1

  sinon.assert.expose(this); This will give you assertCalled(spy),assertCallOrder(spy1, spy2, ...) and so on. The method accepts an optional options object with two options.

method fail

fail: (message?: string) => void;

• Every assertion fails by calling this method. By default it throws an error of type sinon.assert.failException. If the test framework looks for assertion errors by checking for a specific exception, you can simply override the kind of exception thrown. If that does not fit with your testing framework of choice, override the fail method to do the right thing.

method match

match: (actual: any, expected: any) => void;

• Uses sinon.match to test if the arguments can be considered a match.

method neverCalledWith

neverCalledWith: <TArgs extends any[]>(

        exception: string
    ): void;
    (
        spyOrSpyCall: SinonSpyCall<any, any> | SinonSpy<any, any>,
        exception: any
    ): void;
};

method withArgs

withArgs: (...args: any[]) => SinonExpectation;

• Expect the method to be called with the provided arguments and possibly others. An expectation instance only holds onto a single set of arguments specified with withArgs. Subsequent calls will overwrite the previously-specified set of arguments (even if they are different), so it is generally not intended that this method be invoked more than once per test case.

  Parameter args

method withExactArgs

withExactArgs: (...args: any[]) => SinonExpectation;

• Expect the method to be called with the provided arguments and no others. An expectation instance only holds onto a single set of arguments specified with withExactArgs. Subsequent calls will overwrite the previously-specified set of arguments (even if they are different), so it is generally not intended that this method be invoked more than once per test case.

  Parameter args

method create

create: (methodName?: string) => SinonExpectation;

• Creates an expectation without a mock object, basically an anonymous mock function. Method name is optional and is used in exception messages to make them more readable.

    val: any
) => SinonSpy<TArgs, TReturnValue>;

call signature

<TArgs extends readonly any[] = any[], TReturnValue = any>(
    fn: (...args: TArgs) => TReturnValue
): SinonSpy<TArgs, TReturnValue>;

• You can inspect the server.requests to verify request ordering, find unmatched requests or check that no requests has been done. server.requests is an array of all the FakeXMLHttpRequest objects that have been created.

method getHTTPMethod

getHTTPMethod: (request: SinonFakeXMLHttpRequest) => string;

• Used internally to determine the HTTP method used with the provided request. By default this method simply returns request.method. When server.fakeHTTPMethods is true, the method will return the value of the _method parameter if the method is “POST”. This method can be overridden to provide custom behavior.

  Parameter request

method respond

respond: () => void;

• Causes all queued asynchronous requests to receive a response. If none of the responses added through respondWith match, the default response is [404, {}, ""]. Synchronous requests are responded to immediately, so make sure to call respondWith upfront. If called with arguments, respondWith will be called with those arguments before responding to requests.

method respondWith

respondWith: {
    (body: string): void;
    (response: any[]): void;
    (fn: (xhr: SinonFakeXMLHttpRequest) => void): void;

    (url: RegExp, response: any[]): void;
    (url: RegExp, fn: (xhr: SinonFakeXMLHttpRequest) => void): void;
    (method: string, url: RegExp, body: string): void;
    (method: string, url: RegExp, response: any[]): void;
    (
        method: string,
        url: RegExp,
        fn: (xhr: SinonFakeXMLHttpRequest) => void
    ): void;
};

• Causes the server to respond to any request not matched by another response with the provided data. The default catch-all response is [404, {}, ""]. A String representing the response body An Array with status, headers and response body, e.g. [200, { "Content-Type": "text/html", "Content-Length": 2 }, "OK"] A Function. Default status is 200 and default headers are none. When the response is a Function, it will be passed the request object. You must manually call respond on it to complete the request.

  Parameter body

  A String representing the response body

• Causes the server to respond to any request not matched by another response with the provided data. The default catch-all response is [404, {}, ""]. Default status is 200 and default headers are none. When the response is a Function, it will be passed the request object. You must manually call respond on it to complete the request.

  Parameter response

  An Array with status, headers and response body, e.g. [200, { "Content-Type": "text/html", "Content-Length": 2 }, "OK"]

• Causes the server to respond to any request not matched by another response with the provided data. The default catch-all response is [404, {}, ""]. Default status is 200 and default headers are none. When the response is a Function, it will be passed the request object. You must manually call respond on it to complete the request.

  Parameter fn

  A Function.

• Responds to all requests to given URL, e.g. /posts/1.

• Responds to all method requests to the given URL with the given response. method is an HTTP verb.

• URL may be a regular expression, e.g. /\/post\//\d+ If the response is a Function, it will be passed any capture groups from the regular expression along with the XMLHttpRequest object:

• Responds to all method requests to URLs matching the regular expression.

method restore

restore: () => void;

property autoRespond

autoRespond: boolean;

• When set to true, causes the server to automatically respond to incoming requests after a timeout. The default timeout is 10ms but you can control it through the autoRespondAfter property. Note that this feature is intended to help during mockup development, and is not suitable for use in tests.

property autoRespondAfter

autoRespondAfter: number;

• When autoRespond is true, respond to requests after this number of milliseconds. Default is 10.

property fakeHTTPMethods

fakeHTTPMethods: boolean;

• If set to true, server will find _method parameter in POST body and recognize that as the actual method. Supports a pattern common to Ruby on Rails applications. For custom HTTP method faking, override server.getHTTPMethod(request).

property respondImmediately

respondImmediately: boolean;

• If set, the server will respond to every request immediately and synchronously. This is ideal for faking the server from within a test without having to call server.respond() after each request made in that test. As this is synchronous and immediate, this is not suitable for simulating actual network latency in tests or mockups. To simulate network latency with automatic responses, see server.autoRespond and server.autoRespondAfter.

        url: string,
        async: boolean,
        username: string,
        password: string
    ) => boolean
) => void;

• Add a filter that will decide whether or not to fake a request. The filter will be called when xhr.open is called, with the exact same arguments (method, url, async, username, password). If the filter returns true, the request will not be faked.

  Parameter filter

method onCreate

onCreate: (xhr: SinonFakeXMLHttpRequest) => void;

• Works exactly like sinon.stub.

method createStubInstance

createStubInstance: <TType>(
    constructor: StubbableType<TType>,
    overrides?: {
        [K in keyof TType]?:
            | SinonStubbedMember<TType[K]>
            | (TType[K] extends (...args: any[]) => infer R ? R : TType[K]);
    }
) => SinonStubbedInstance<TType>;

• Creates a new object with the given functions as the prototype and stubs all implemented functions.

  TType Type being stubbed.

  Parameter constructor

  Object or class to stub.

  Parameter overrides

  An optional map overriding created stubs

  Returns

  A stubbed version of the constructor.

  Remarks

  The given constructor function is not invoked. See also the stub API.

method define

define: (obj: object, key: PropertyKey, value: unknown) => void;

• Defines a property on the given object which will be torn down when the sandbox is restored

method replaceGetter

replaceGetter: <T, TKey extends keyof T>(
    obj: T,
    prop: TKey,
    replacement: () => T[TKey]
) => () => T[TKey];

• Replaces getter for property on object with replacement argument. Attempts to replace an already replaced getter cause an exception. replacement must be a Function, and can be instances of spies, stubs and fakes.

  Parameter obj

  Parameter prop

  Parameter replacement

method replaceSetter

replaceSetter: <T, TKey extends keyof T>(
    obj: T,
    prop: TKey,
    replacement: (val: T[TKey]) => void
) => (val: T[TKey]) => void;

• Replaces setter for property on object with replacement argument. Attempts to replace an already replaced setter cause an exception. replacement must be a Function, and can be instances of spies, stubs and fakes.

  Parameter obj

  Parameter prop

  Parameter replacement

method reset

reset: () => void;

• Resets the internal state of all fakes created through sandbox.

method resetBehavior

resetBehavior: () => void;

• Resets the behaviour of all stubs created through the sandbox. Since sinon@2.0.0

method resetHistory

resetHistory: () => void;

• Resets the history of all stubs created through the sandbox. Since sinon@2.0.0

method restore

restore: () => void;

• Restores all fakes created through sandbox.

method useFakeServer

useFakeServer: () => SinonFakeServer;

• Fakes XHR and binds a server object to the sandbox such that it too is restored when calling sandbox.restore(). Access requests through sandbox.requests and server through sandbox.server

method useFakeTimers

useFakeTimers: (
    config?: number | Date | Partial<FakeTimers.FakeTimerInstallOpts>
) => SinonFakeTimers;

• * No param : Causes Sinon to replace the global setTimeout, clearTimeout, setInterval, clearInterval, setImmediate, clearImmediate, process.hrtime, performance.now(when available) and Date with a custom implementation which is bound to the returned clock object. Starts the clock at the UNIX epoch (timestamp of 0). * Now : As above, but rather than starting the clock with a timestamp of 0, start at the provided timestamp now. Since sinon@2.0.0 You can also pass in a Date object, and its getTime() will be used for the starting timestamp. * Config : As above, but allows further configuration options, some of which are: * config.now - Number/Date - installs lolex with the specified unix epoch (default: 0) * config.toFake - String[ ] - an array with explicit function names to fake. By default lolex will automatically fake all methods except process.nextTick. You could, however, still fake nextTick by providing it explicitly * config.shouldAdvanceTime - Boolean - tells lolex to increment mocked time automatically based on the real system time shift (default: false) * Please visit the lolex.install documentation for the full feature set. * Important note: when faking nextTick, normal calls to process.nextTick() would not execute automatically as they would during normal event-loop phases. You would have to call either clock.next(), clock.tick(), clock.runAll() or clock.runToLast() (see example below). Please refer to the lolex documentation for more information.

  Parameter config

method useFakeXMLHttpRequest

useFakeXMLHttpRequest: () => SinonFakeXMLHttpRequestStatic;

• Causes Sinon to replace the native XMLHttpRequest object in browsers that support it with a custom implementation which does not send actual requests. In browsers that support ActiveXObject, this constructor is replaced, and fake objects are returned for XMLHTTP progIds. Other progIds, such as XMLDOM are left untouched. The native XMLHttpRequest object will be available at sinon.xhr.XMLHttpRequest

method usingPromise

usingPromise: (promiseLibrary: any) => SinonSandbox;

• Causes all stubs created from the sandbox to return promises using a specific Promise library instead of the global one when using stub.rejects or stub.resolves. Returns the stub to allow chaining. Since sinon@2.0.0

method verify

verify: () => void;

• Verifies all mocks created through the sandbox.

method verifyAndRestore

verifyAndRestore: () => void;

• Verifies all mocks and restores all fakes created through the sandbox.

property assertOptions

assertOptions: {
    shouldLimitAssertionLogs?: boolean;
    assertionLogLimit?: number;
};

• The assert options can help limit the amount of output produced by assert.fail

property injectInto

injectInto: object | null;

• The sandbox’s methods can be injected into another object for convenience. The injectInto configuration option can name an object to add properties to.

property properties

properties: string[];

• What properties to inject. Note that simply naming “server” here is not sufficient to have a server property show up in the target object, you also have to set useFakeServer to true.

property useFakeServer

useFakeServer: boolean | SinonFakeServer;

• If true, server and requests properties are added to the sandbox. Can also be an object to use for fake server. The default one is sinon.fakeServer, but if you’re using jQuery 1.3.x or some other library that does not set the XHR’s onreadystatechange handler, you might want to do:

property useFakeTimers

useFakeTimers: boolean | Partial<FakeTimers.FakeTimerInstallOpts>;

• If set to true, the sandbox will have a clock property. You can optionally pass in a configuration object that follows the specification for fake timers, such as { toFake: ["setTimeout", "setInterval"] }.

method contains

contains: (expected: SimplifiedSet) => SinonMatcher;

• Requires a Set to contain each one of the items the given set has.

method deepEquals

deepEquals: (expected: SimplifiedSet) => SinonMatcher;

• Requires a Set to be deep equal another one.
