Released by Carl-Erik Kopseng on 2024-09-10.

18.0.0

This is what 17.0.2 should have been, as that contained two breaking changes. After updating Nise we are down to one breaking change, which only affects sinon-test (which has been updated), so most people are not affected. The legacyRoutes flag that is currently enabled in Nise by default will at some later version be disabled. We will then issue a little migration note.

01d45312 Use Nise 6 with legacyRoutes flag enabled (Carl-Erik Kopseng)

This should be disabled in a future Sinon version by default.

66b0081e Use fake-timers v10.1.0 re-released as v10.3.0 (Carl-Erik Kopseng)

Version 10.2.0 of fake-timers had an unexpected breaking change. We re-released 10.1.0 as 10.3.0 to force users into jumping over the deprecated version.

v10.2.0 was re-released as v11.0.0 and will be part of the next Sinon major

d220c995 fix: bundling compatibility with webpack@5 (#2519) (Avi Vahl)
- fix: bundling compatibility with webpack@5
when using webpack v5 to bundle code that calls require('sinon') (cjs) , it would have defaulted to "exports->require" and fail with multiple node-api requirements (util, timers, etc.)

this patch ensures that anyone who bundles sinon for browser gets the (browser-compatible) esm version.

tested on both webpack v5 and v4. should be noted that v4 worked even without this patch, as it automatically injected polyfills. v5 no longer does so. with this PR, people using webpack@4 to bundle sinon at least see size improvement, as the polyfills are no longer required.
- fix: revert change for package.json -> "browser"
browserify doesn't seem to like esm. leave that entry point alone, and ensure "exports" -> "browser" (which webpack@5 uses) is esm.

Released by Carl-Erik Kopseng on 2023-06-20.

15.1.2

02b73aed Update lock file after removing node_modules ... (Carl-Erik Kopseng)

Released by Carl-Erik Kopseng on 2023-06-12.

15.1.1

194fc2ef Change fake-timers version to specifically target the one containing the 'jump' feature (Carl-Erik Kopseng)

Instead of the later (breaking) version. See #470
05f05ac3 docs: Remove threw(obj) from docs (#2513) (Morgan Roderick)
Since the introduction of threw in

0feec9ffba0da6bc2996cefa0c6e71872e8bedb2, no one have reported that

threw(obj) doesn't work as the documentation states.
```
const sinon = require("sinon");

const o = { pie: "apple" };

const f = sinon.fake.throws(o);

f();

// this is supposed to return true

f.threw(o);

// => false
```
Since it has been 12+ years without an error report, it's safe to assume

that no one uses the threw method in this way. Let's remove it from

the documentation.

6cbde9b0 fix throws().callsFake() precedence (#2497) (Eduardo Diaz)

05341dcf Update npm version scripts to manage new releases branch (Joel Bradshaw)
fe658261 Remove release archives from master (Joel Bradshaw)

These archives made it difficult to find things in the GitHub interface, and take up a lot of space in a checked-out repo for something that is not useful to most people checking out the repository.

The main purpose of these archives is to make old versions and documentation available on the Sinon website that is run out of this repo. This can be supported by using a separate branch for website releases, and to maintain the archives.

Following this commit, the npm version scripts will be updated to automatically handle archiving the releases in the new releases branch and keeping it up to date with master.

Also remove the directories we removed from .prettierignore, since they don't exist any more.

Released by Carl-Erik Kopseng on 2022-02-01.

1.4.2

sinon.match for arrays (Maximilian Antoni)

1.4.1

Strengthen a Node.JS inference to avoid quirky behavior with Mocha (which provides a shim process object)

1.4.0

Argument matchers (Maximilian Antoni) sinon.match.{any, same, typeOf, instanceOf, has, hasOwn, defined, truthy, falsy} as well as typeOf shortcuts for boolean, number, string, object, function, array, regexp and date. The result of a call can be used with spy.calledWith.
spy.returned now works with matchers and compares objects deeply.

calledWithNew and alwaysCalledWithNew for assert (Maximilian Antoni)
Easier stubbed fluent interfaces: stub.returnsThis() (Glen Mailer)

New methods stub.callsArgOn, stub.callsArgOnWith, stub.yieldsOn, stub.yieldsToOn
Implemented
Fixing clearTimeout to not throw when called for nonexistent IDs.
Spys that are created using 'withArgs' now get initialized with previous calls to the original spy.
Minor bug fixes and docs cleanup.

1.3.1

Fix bug in core sinon: isNode was used for both a variable and a function, causing load errors and lots of bugs. Should have never left the door.

1.3.0

Support using bare functions as fake server response handlers (< 1.3.0 required URL and/or method matcher too)
Log some internal errors to sinon.log (defaults to noop). Set sinon.log to your logging utility of choice for better feedback when.
White-list fake XHRs: Allows some fake requests and some that fall through to the backend server (Tim Ruffles)
Decide Date.now support at fake-time. Makes it possible to load something that polyfills Date.now after Sinon loaded and still have Date.now on fake Dates.
Mirror properties on replaced function properties
New methods: spy.yield(), spy.yieldTo(), spy.callArg() and spy.callArgWith() can be used to invoke callbacks passed to spies (while avoiding the mock-like upfront yields() and friends). invokeCallback is available as an alias for yield for people working with strict mode. (Maximilian Antoni)
New properties: spy.firstCall, spy.secondCall, spy.thirdCall and spy.lastCall. (Maximilian Antoni)
New method: stub.returnsArg(), causes stub to return one of its arguments. (Gavin Huang)
Stubs now work for inherited methods. This was previously prohibited to avoid stubbing not-yet-implemented methods. (Felix Geisendörfer)
server.respond() can now accept the same arguments as server.respondWith() for quick-and-dirty respondWith+respond. (Gavin Huang)
Format objects with buster-format in the default bundle. Default to util.inspect on node unless buster-format is available (not a hard dependency, more like a 'preference').
Bug fix: Make sure XHRs can complete even if onreadystatechange handler fails
Bug fix: Mirror entire Date.prototype, including toUTCString when faking
Bug fix: Default this object to global in exposed asserts
Bug fix: sinon.test: use try/finally instead of catch and throw - preserves stack traces (Kevin Turner)
Bug fix: Fake setTimeout now returns ids greater than 0. (Domenic Denicola)
Bug fix: NPM install warning (Felix Geisendörfer)
Bug fix: Fake timers no longer swallows exceptions (Felix Geisendörfer)
Bug fix: Properly expose all needed asserts for node
Bug fix: wrapMethod on window property (i.e. when stubbing/spying on global functions)
Bug fix: Quote "yield" (Ben Hockey)
Bug fix: callOrder works correctly when spies have been called multiple times

1.2.0

Bug fix: abort() switches state to DONE when OPENED and sent. Fix by Tristan Koch.
Bug fix: Mootools uses MSXML2.XMLHTTP as objectId, which Sinon matched with different casing. Fix by Olmo Maldonado.
Bug fix: When wrapping a non-owned property, restore now removes the wrapper instead of replacing it. Fix by Will Butler.
Bug fix: Make it possibly to stub Array.prototype.push by not using that method directly inside Sinon.
Bug fix: Don't assume that req.requestBody is a string in the fake server.
Added spy.printf(format) to print a nicely formatted message with details about a spy.
Garbage collection: removing fakes from collections when restoring the original methods. Fix by Tristan Koch.
Add spy.calledWithNew to check if a function was used as a constructor
Add spy.notCalledWith(), spy.neverCalledWith() and sinon.assert.neverCalledWith. By Max Antoni
Publicly expose sinon.expectation.fail to allow tools to integrate with mock expectations.
Fake XMLHttpRequests now support a minimal portion of the events API, making them work seamlessly with e.g. SproutCode (which uses xhr.addEventListener("readystatechange"). Partially by Sven Fuchs.

1.1.1

Fix broken mock verification in CommonJS when not including the full Sinon package.

1.1.0

The fake server now has a autoRespond method which allows it to respond to requests on the fly (asynchronously), making it a good fit for mockup development
Stubs and spies now has a withArgs method. Using it allows you to create several spies/stubs for the same method, filtered by received arguments
Stubs now has yields and yieldsTo methods for fuzzily invoking callbacks. They work like callsArgAt only by inferring what callback to invoke, and yieldsTo can invoke callbacks in object "options" arguments.
Allow sandboxes/collections to stub any property so long as the object has the property as an own property
Significantly improve error reporting from failed mock expectations. Now prints all met and unmet expectations with expected and received arguments
Allow mock expectations to be consumed in any order
Add pretty printing of all calls when assertions fail
Fix bug: Stub exception message ended up as "undefined" (string) if not specified
Pass capture groups in URLs to fakeServer function handlers
Pass through return value from test function in testCase
typeof require is not enough to assume node, also use typeof module
Don't use Object.create in sinon.create. In the off chance that someone stubs it, sinon will fail mysteriously (Thanks to Espen Dalløkken)
Catch exceptions when parsing DOM elements "on a hunch" When responding to XHRs, Sinon acts like most browsers and try to parse the response into responseXML if Content-Type indicates XML or HTML. However, it also does this if the type is not set. Obviously, this may misfire and should be caught.
Fix fakeServer.respond() to not drop requests when they are queued during the processing of an existing queue. (Sven Fuchs)
Clean up module loading in CommonJS environments (Node.js still the only tested such environment). No longer (temporarily) modifies require.paths, always loads all modules.

1.0.2

Fix JSON bug in package.json
Sandbox no longer tries to use a fake server if config says so, but server is not loaded

1.0.1

Make sure sinon.sandbox is exposed in node.js (fix by Gord Tanner)

1.0.0

Switched indentation from 2 to 4 spaces :)
Node.js compatibility improvements
Remove magic booleans from sinon.assert.expose, replace with option object
Put QUnit adapter in its own repository
Update build script to build standalone timers and server files
Breaking change: thisObj -> thisValue Change brings consistency to the code-base, always use thisValue
Add sinon.assert.pass callback for successful assertions
Extract sandbox configuration from sinon.test

Refactored sinon.test to not do all the heavy lifting in creating sandbox objects from sinon.config. Now sinon.sandbox.create accepts an optional configuration that can be retrieved through sinon.getConfig({ ... }) - or, to match previous behavior, through sinon.getConfig(sinon.config);

The default configuration now lives in sinon.defaultConfig rather than the previous sinon.test.

This change enables external tools, such as test framework adapters, to easily create configurable sandboxes without going through sinon.test
Rewrite sinon.clock.tick to fix bug and make implementation clearer
Test config load correct files
Make timers and XHR truly standalone by splitting the IE work-around in two files
Don't fail when comparing DOM elements in sinon.deepEqual (used in calledWith(...))
Should mirror properties on Date when faking it
Added and updated configuration for both JsLint and JavaScript lint
[August Lilleaas] The build script can optionally build a file without the version name in it, by passing 'plain', i.e. './build plain'.

Useful when using the build script to build and use sinon programatically, so one can 'cp path/to/sinon/pkg/sinon.js my/scripts/'
[August Lilleaas] Checking and warning if we got a load error and rubygems isn't present.
[August Lilleaas] Updating build script to be runnable from any directory. Current working directory doesn't have to be repo root.

0.8.0

sinon.wrapMethod no longer accepts faking already faked methods
sinon-qunit 'plugin'
sinon.test / sinon.config can now expose the sandbox object

0.7.2

Add sinon.sandbox.create back in
Fix bug where clock.tick would fire timeouts in intervals when setInterval was also called

0.7.1

The fake server will now match paths against full URLs, meaning that server.respondWith("/", "OK"); will match requests for "http://currentHost/".
Improved toString method for spies and stubs which leads to more precise error messages from sinon.assert.*

0.7.0

sinon.useFakeTimers now fakes the Date constructor by default
sinon.testCase now fakes XHR and timers by default
sinon.config controls the behavior of sinon.testCase
Fixed bug in clock.tick - now fires timers in correct order
Added the ability to tick a clock string for longer ticks. Passing a number causes the clock to tick the specified amount of milliseconds, passing a string like "12:32" ticks 12 minutes and 32 seconds.
calledBefore and calledAfter for individual calls
New assertions sinon.assert.notCalled sinon.assert.calledOnce sinon.assert.calledTwice sinon.assert.calledThrice
sinon.test now throws if passed anything other than a function
sinon.testCase now throws if passed anything other than an object
sinon.{spy,stub}(obj, method) now throws if the property is not an existing function - helps avoid perpetuating typo bugs
Vastly improved error messages from assertions
Spies/stubs/expectations can have their names resolved in many cases
Removed feature where sinon.testCase allowed for nested test cases (does not belong in Sinon.JS)
Organizational change: src/ becomes lib/ Helps npm compatibility
Thanks to Cory Flanigan for help on npm compatibility

0.6.2

Fixed another bug in sinon.fakeServerWithClock where consecutive respond() calls did not trigger timeouts.

0.6.1

Fixed a bug in sinon.fakeServerWithClock where the clock was ticked before the server had responded to all requests, resulting in objects not having been responded to by the time the timeout ran.

0.6.0

FakeXMLHttpRequest
sinon.useFakeXMLHttpRequest
sinon.fakeServer
sinon.fakeServerWithClock
Improved fake timers implementation, made them work properly in IE 6-8
Improved sinon.sandbox
- Added useFakeServer
- Added inject method
Improved sinon.test method
- Made configuration aware
- Now uses sinon.sandbox in place of sinon.collection
Changed default configuration for sinon.test, breaking compatibility with 0.5.0 - can be changed through sinon.config

0.5.0

Initial release
Spies, stubs, mocks
Assertions
collections, test, testCase
Fake timers (half-baked)
