class Assertion {
__flags = {};
* Creates object for chaining.
* `Assertion` objects contain metadata in the form of flags. Three flags can
* be assigned during instantiation by passing arguments to this constructor:
*
* - `object`: This flag contains the target of the assertion. For example, in
* the assertion `expect(numKittens).to.equal(7);`, the `object` flag will
* contain `numKittens` so that the `equal` assertion can reference it when
* needed.
*
* - `message`: This flag contains an optional custom error message to be
* prepended to the error message that's generated by the assertion when it
* fails.
*
* - `ssfi`: This flag stands for "start stack function indicator". It
* contains a function reference that serves as the starting point for
* removing frames from the stack trace of the error that's created by the
* assertion when it fails. The goal is to provide a cleaner stack trace to
* end users by removing Chai's internal functions. Note that it only works
* in environments that support `Error.captureStackTrace`, and only when
* `Chai.config.includeStack` hasn't been set to `false`.
*
* - `lockSsfi`: This flag controls whether or not the given `ssfi` flag
* should retain its current value, even as assertions are chained off of
* this object. This is usually set to `true` when creating a new assertion
* from within another assertion. It's also temporarily set to `true` before
* an overwritten assertion gets called by the overwriting assertion.
*
* - `eql`: This flag contains the deepEqual function to be used by the assertion.
*
* @param {unknown} obj target of the assertion
* @param {string} [msg] (optional) custom error message
* @param {Function} [ssfi] (optional) starting point for removing stack frames

* ### .include(val[, msg])
*
* When the target is a string, `.include` asserts that the given string `val`
* is a substring of the target.
*
* expect('foobar').to.include('foo');
*
* When the target is an array, `.include` asserts that the given `val` is a
* member of the target.
*
* expect([1, 2, 3]).to.include(2);
*
* When the target is an object, `.include` asserts that the given object
* `val`'s properties are a subset of the target's properties.
*
* expect({a: 1, b: 2, c: 3}).to.include({a: 1, b: 2});
*
* When the target is a Set or WeakSet, `.include` asserts that the given `val` is a
* member of the target. SameValueZero equality algorithm is used.
*
* expect(new Set([1, 2])).to.include(2);
*
* When the target is a Map, `.include` asserts that the given `val` is one of
* the values of the target. SameValueZero equality algorithm is used.
*
* expect(new Map([['a', 1], ['b', 2]])).to.include(2);
*
* Because `.include` does different things based on the target's type, it's
* important to check the target's type before using `.include`. See the `.a`
* doc for info on testing a target's type.
*
* expect([1, 2, 3]).to.be.an('array').that.includes(2);
*
* By default, strict (`===`) equality is used to compare array members and
* object properties. Add `.deep` earlier in the chain to use deep equality
* instead (WeakSet targets are not supported). See the `deep-eql` project
* page for info on the deep equality algorithm: https://github.com/chaijs/deep-eql.
*
* // Target array deeply (but not strictly) includes `{a: 1}`
* expect([{a: 1}]).to.deep.include({a: 1});
* expect([{a: 1}]).to.not.include({a: 1});
*
* // Target object deeply (but not strictly) includes `x: {a: 1}`
* expect({x: {a: 1}}).to.deep.include({x: {a: 1}});
* expect({x: {a: 1}}).to.not.include({x: {a: 1}});
*
* By default, all of the target's properties are searched when working with
* objects. This includes properties that are inherited and/or non-enumerable.
* Add `.own` earlier in the chain to exclude the target's inherited
* properties from the search.
*
* Object.prototype.b = 2;
*
* expect({a: 1}).to.own.include({a: 1});
* expect({a: 1}).to.include({b: 2}).but.not.own.include({b: 2});
*
* Note that a target object is always only searched for `val`'s own
* enumerable properties.
*
* `.deep` and `.own` can be combined.
*
* expect({a: {b: 2}}).to.deep.own.include({a: {b: 2}});
*
* Add `.nested` earlier in the chain to enable dot- and bracket-notation when
* referencing nested properties.
*
* expect({a: {b: ['x', 'y']}}).to.nested.include({'a.b[1]': 'y'});
*
* If `.` or `[]` are part of an actual property name, they can be escaped by
* adding two backslashes before them.
*
* expect({'.a': {'[b]': 2}}).to.nested.include({'\\.a.\\[b\\]': 2});
*
* `.deep` and `.nested` can be combined.
*
* expect({a: {b: [{c: 3}]}}).to.deep.nested.include({'a.b[0]': {c: 3}});
*
* `.own` and `.nested` cannot be combined.
*
* Add `.not` earlier in the chain to negate `.include`.
*
* expect('foobar').to.not.include('taco');
* expect([1, 2, 3]).to.not.include(4);
*
* However, it's dangerous to negate `.include` when the target is an object.
* The problem is that it creates uncertain expectations by asserting that the
* target object doesn't have all of `val`'s key/value pairs but may or may
* not have some of them. It's often best to identify the exact output that's
* expected, and then write an assertion that only accepts that exact output.
*
* When the target object isn't even expected to have `val`'s keys, it's
* often best to assert exactly that.
*
* expect({c: 3}).to.not.have.any.keys('a', 'b'); // Recommended
* expect({c: 3}).to.not.include({a: 1, b: 2}); // Not recommended
*
* When the target object is expected to have `val`'s keys, it's often best to
* assert that each of the properties has its expected value, rather than
* asserting that each property doesn't have one of many unexpected values.
*
* expect({a: 3, b: 4}).to.include({a: 3, b: 4}); // Recommended
* expect({a: 3, b: 4}).to.not.include({a: 1, b: 2}); // Not recommended
*
* `.include` accepts an optional `msg` argument which is a custom error
* message to show when the assertion fails. The message can also be given as
* the second argument to `expect`.
*
* expect([1, 2, 3]).to.include(4, 'nooo why fail??');
* expect([1, 2, 3], 'nooo why fail??').to.include(4);
*
* `.include` can also be used as a language chain, causing all `.members` and
* `.keys` assertions that follow in the chain to require the target to be a
* superset of the expected set, rather than an identical set. Note that
* `.members` ignores duplicates in the subset when `.include` is added.
*
* // Target object's keys are a superset of ['a', 'b'] but not identical
* expect({a: 1, b: 2, c: 3}).to.include.all.keys('a', 'b');
* expect({a: 1, b: 2, c: 3}).to.not.have.all.keys('a', 'b');
*
* // Target array is a superset of [1, 2] but not identical
* expect([1, 2, 3]).to.include.members([1, 2]);
* expect([1, 2, 3]).to.not.have.members([1, 2]);
*
* // Duplicates in the subset are ignored
* expect([1, 2, 3]).to.include.members([1, 2, 2, 2]);
*
* Note that adding `.any` earlier in the chain causes the `.keys` assertion
* to ignore `.include`.
*
* // Both assertions are identical
* expect({a: 1}).to.include.any.keys('a', 'b');
* expect({a: 1}).to.have.any.keys('a', 'b');
*

* interchangeably with `.include`.

*
* When `val` is provided, `.property` also asserts that the property's value
* is equal to the given `val`.

*
* By default, strict (`===`) equality is used. Add `.deep` earlier in the

* expect({x: {a: 1}}).to.not.have.property('x', {a: 1});
*
* The target's enumerable and non-enumerable properties are always included

* Add `.own` earlier in the chain to exclude inherited properties from the
* search.

*
* `.deep` and `.own` can be combined.
*
* expect({x: {a: 1}}).to.have.deep.own.property('x', {a: 1});
*
* Add `.nested` earlier in the chain to enable dot- and bracket-notation when
* referencing nested properties.
*
* expect({a: {b: ['x', 'y']}}).to.have.nested.property('a.b[1]');
* expect({a: {b: ['x', 'y']}}).to.have.nested.property('a.b[1]', 'y');

* Add `.not` earlier in the chain to negate `.property`.
*
* expect({a: 1}).to.not.have.property('b');
*
* However, it's dangerous to negate `.property` when providing `val`. The
* problem is that it creates uncertain expectations by asserting that the
* target either doesn't have a property with the given key `name`, or that it
* does have a property with the given key `name` but its value isn't equal to
* the given `val`. It's often best to identify the exact output that's
* expected, and then write an assertion that only accepts that exact output.
*
* When the target isn't expected to have a property with the given key
* `name`, it's often best to assert exactly that.
*
* expect({b: 2}).to.not.have.property('a'); // Recommended
* expect({b: 2}).to.not.have.property('a', 1); // Not recommended
*
* When the target is expected to have a property with the given key `name`,
* it's often best to assert that the property has its expected value, rather
* than asserting that it doesn't have one of many unexpected values.
*
* expect({a: 3}).to.have.property('a', 3); // Recommended
* expect({a: 3}).to.not.have.property('a', 1); // Not recommended
*
* `.property` changes the target of any assertions that follow in the chain
* to be the value of the property from the original target object.
*
* expect({a: 1}).to.have.property('a').that.is.a('number');
*
* `.property` accepts an optional `msg` argument which is a custom error
* message to show when the assertion fails. The message can also be given as
* the second argument to `expect`. When not providing `val`, only use the
* second form.
*
* // Recommended

* expect(new Map([['a', 1], ['b', 2]])).to.have.all.keys('a', 'b');
* expect(new Set(['a', 'b'])).to.have.all.keys('a', 'b');

* expect(new Set([{a: 1}])).to.not.have.all.keys([{a: 1}]);
*
* By default, the target must have all of the given keys and no more. Add
* `.any` earlier in the chain to only require that the target have at least
* one of the given keys. Also, add `.not` earlier in the chain to negate
* `.keys`. It's often best to add `.any` when negating `.keys`, and to use
* `.all` when asserting `.keys` without negation.
*
* When negating `.keys`, `.any` is preferred because `.not.any.keys` asserts

*
* // Not recommended; asserts that target has at least one of the given
* // keys but may or may not have more of them
* expect({a: 1, b: 2}).to.have.any.keys('a', 'b');
*
* Note that `.all` is used by default when neither `.all` nor `.any` appear
* earlier in the chain. However, it's often best to add `.all` anyway because
* it improves readability.
*
* // Both assertions are identical
* expect({a: 1, b: 2}).to.have.all.keys('a', 'b'); // Recommended
* expect({a: 1, b: 2}).to.have.keys('a', 'b'); // Not recommended

* ### .throw([errorLike], [errMsgMatcher], [msg])
*
* When no arguments are provided, `.throw` invokes the target function and
* asserts that an error is thrown.
*
* var badFn = function () { throw new TypeError('Illegal salmon!'); };
* expect(badFn).to.throw();
*
* When one argument is provided, and it's an error constructor, `.throw`
* invokes the target function and asserts that an error is thrown that's an
* instance of that error constructor.
*
* var badFn = function () { throw new TypeError('Illegal salmon!'); };
* expect(badFn).to.throw(TypeError);
*
* When one argument is provided, and it's an error instance, `.throw` invokes
* the target function and asserts that an error is thrown that's strictly
* (`===`) equal to that error instance.
*
* var err = new TypeError('Illegal salmon!');
* var badFn = function () { throw err; };
*
* expect(badFn).to.throw(err);
*
* When one argument is provided, and it's a string, `.throw` invokes the
* target function and asserts that an error is thrown with a message that
* contains that string.
*
* var badFn = function () { throw new TypeError('Illegal salmon!'); };
* expect(badFn).to.throw('salmon');
*
* When one argument is provided, and it's a regular expression, `.throw`
* invokes the target function and asserts that an error is thrown with a
* message that matches that regular expression.
*
* var badFn = function () { throw new TypeError('Illegal salmon!'); };
* expect(badFn).to.throw(/salmon/);
*
* When two arguments are provided, and the first is an error instance or
* constructor, and the second is a string or regular expression, `.throw`
* invokes the function and asserts that an error is thrown that fulfills both
* conditions as described above.
*
* var err = new TypeError('Illegal salmon!');
* var badFn = function () { throw err; };
*
* expect(badFn).to.throw(TypeError, 'salmon');
* expect(badFn).to.throw(TypeError, /salmon/);
* expect(badFn).to.throw(err, 'salmon');
* expect(badFn).to.throw(err, /salmon/);
*
* Add `.not` earlier in the chain to negate `.throw`.
*
* var goodFn = function () {};
* expect(goodFn).to.not.throw();
*
* However, it's dangerous to negate `.throw` when providing any arguments.
* The problem is that it creates uncertain expectations by asserting that the
* target either doesn't throw an error, or that it throws an error but of a
* different type than the given type, or that it throws an error of the given
* type but with a message that doesn't include the given string. It's often
* best to identify the exact output that's expected, and then write an
* assertion that only accepts that exact output.
*
* When the target isn't expected to throw an error, it's often best to assert
* exactly that.
*
* var goodFn = function () {};
*
* expect(goodFn).to.not.throw(); // Recommended
* expect(goodFn).to.not.throw(ReferenceError, 'x'); // Not recommended
*
* When the target is expected to throw an error, it's often best to assert
* that the error is of its expected type, and has a message that includes an
* expected string, rather than asserting that it doesn't have one of many
* unexpected types, and doesn't have a message that includes some string.
*
* var badFn = function () { throw new TypeError('Illegal salmon!'); };
*
* expect(badFn).to.throw(TypeError, 'salmon'); // Recommended
* expect(badFn).to.not.throw(ReferenceError, 'x'); // Not recommended
*
* `.throw` changes the target of any assertions that follow in the chain to
* be the error object that's thrown.
*
* var err = new TypeError('Illegal salmon!');
* err.code = 42;
* var badFn = function () { throw err; };
*
* expect(badFn).to.throw(TypeError).with.property('code', 42);
*
* `.throw` accepts an optional `msg` argument which is a custom error message
* to show when the assertion fails. The message can also be given as the
* second argument to `expect`. When not providing two arguments, always use
* the second form.
*
* var goodFn = function () {};
*
* expect(goodFn).to.throw(TypeError, 'x', 'nooo why fail??');
* expect(goodFn, 'nooo why fail??').to.throw();
*
* Due to limitations in ES5, `.throw` may not always work as expected when
* using a transpiler such as Babel or TypeScript. In particular, it may
* produce unexpected results when subclassing the built-in `Error` object and
* then passing the subclassed constructor to `.throw`. See your transpiler's
* docs for details:
*
* - ([Babel](https://babeljs.io/docs/usage/caveats/#classes))
* - ([TypeScript](https://github.com/Microsoft/TypeScript/wiki/Breaking-Changes#extending-built-ins-like-error-array-and-map-may-no-longer-work))
*
* Beware of some common mistakes when using the `throw` assertion. One common
* mistake is to accidentally invoke the function yourself instead of letting
* the `throw` assertion invoke the function for you. For example, when
* testing if a function named `fn` throws, provide `fn` instead of `fn()` as
* the target for the assertion.
*
* expect(fn).to.throw(); // Good! Tests `fn` as desired
* expect(fn()).to.throw(); // Bad! Tests result of `fn()`, not `fn`
*
* If you need to assert that your function `fn` throws when passed certain
* arguments, then wrap a call to `fn` inside of another function.
*
* expect(function () { fn(42); }).to.throw(); // Function expression
* expect(() => fn(42)).to.throw(); // ES6 arrow function
*
* Another common mistake is to provide an object method (or any stand-alone
* function that relies on `this`) as the target of the assertion. Doing so is
* problematic because the `this` context will be lost when the function is
* invoked by `.throw`; there's no way for it to know what `this` is supposed
* to be. There are two ways around this problem. One solution is to wrap the
* method or function call inside of another function. Another solution is to
* use `bind`.
*
* expect(function () { cat.meow(); }).to.throw(); // Function expression
* expect(() => cat.meow()).to.throw(); // ES6 arrow function
* expect(cat.meow.bind(cat)).to.throw(); // Bind
*
* Finally, it's worth mentioning that it's a best practice in JavaScript to
* only throw `Error` and derivatives of `Error` such as `ReferenceError`,
* `TypeError`, and user-defined objects that extend `Error`. No other type of
* value will generate a stack trace when initialized. With that said, the
* `throw` assertion does technically support any type of value being thrown,
* not just `Error` and its derivatives.
*
* The aliases `.throws` and `.Throw` can be used interchangeably with
* `.throw`.

* ### .addLengthGuard(fn, assertionName, isChainable)
*
* Define `length` as a getter on the given uninvoked method assertion. The
* getter acts as a guard against chaining `length` directly off of an uninvoked
* method assertion, which is a problem because it references `function`'s
* built-in `length` property instead of Chai's `length` assertion. When the
* getter catches the user making this mistake, it throws an error with a
* helpful message.
*
* There are two ways in which this mistake can be made. The first way is by
* chaining the `length` assertion directly off of an uninvoked chainable
* method. In this case, Chai suggests that the user use `lengthOf` instead. The
* second way is by chaining the `length` assertion directly off of an uninvoked
* non-chainable method. Non-chainable methods must be invoked prior to
* chaining. In this case, Chai suggests that the user consult the docs for the
* given assertion.
*
* If the `length` property of functions is unconfigurable, then return `fn`
* without modification.
*
* Note that in ES6, the function's `length` property is configurable, so once
* support for legacy environments is dropped, Chai's `length` property can
* replace the built-in function's `length` property, and this length guard will
* no longer be necessary. In the mean time, maintaining consistency across all
* environments is the priority.
