Any constructor

An array-like object (Array, Uint8Array, NodeList, etc.) that is not a string.

Make an assertion, error will be thrown if expr does not have truthy value.

Make an assertion that actual and expected are almost equal numbers through a given tolerance. It can be used to take into account IEEE-754 double-precision floating-point representation limitations. If the values are not almost equal then throw.

Make an assertion that actual includes the expected values. If not then an error will be thrown.

Make an assertion that actual and expected are equal, deeply. If not deeply equal, then throw.

Make an assertion that actual is not null or undefined. If not then throw.

Make an assertion, error will be thrown if expr have truthy value.

Make an assertion that actual is greater than expected. If not then throw.

Make an assertion that actual is greater than or equal to expected. If not then throw.

Make an assertion that obj is an instance of type. If not then throw.

Error thrown when an assertion fails.

Make an assertion that error is an Error. If not then an error will be thrown. An error class and a string that should be included in the error message can also be asserted.

Make an assertion that actual is less than expected. If not then throw.

Make an assertion that actual is less than or equal to expected. If not then throw.

Make an assertion that actual match RegExp expected. If not then throw.

Make an assertion that actual and expected are not equal, deeply. If not then throw.

Make an assertion that obj is not an instance of type. If so, then throw.

Make an assertion that actual not match RegExp expected. If match then throw.

Make an assertion that actual and expected are not strictly equal. If the values are strictly equal then throw.

Make an assertion that actual object is a subset of expected object, deeply. If not, then throw.

Make an assertion that actual and expected are strictly equal. If not then throw.

Make an assertion that actual includes expected. If not then throw.

Deep equality comparison used in assertions

Forcefully throws a failed assertion.

Assertion condition for assertFalse.

Gets constructor type

Use this to stub out methods that will throw when invoked.

Use this to assert unreachable code.

Run some shared teardown after all of the tests in the suite.

Run some shared teardown after each test in the suite.

Run some shared setup before all of the tests in the suite.

Run some shared setup before each test in the suite.

Registers a test suite.

The arguments for a DescribeFunction.

The options for creating a test suite with the describe function.

Registers an individual test case.

The arguments for an ItFunction.

The options for creating an individual test case with the it function.

A group of tests.

Asserts that a spy is called as expected.

Asserts that a spy is called with a specific arg as expected.

Asserts that an spy is called with a specific range of args as expected. If a start and end index is not provided, the expected will be compared against all args. If a start is provided without an end index, the expected will be compared against all args from the start index to the end. The end index is not included in the range of args that are compared.

Asserts that an async spy is called as expected.

Asserts that a spy is called as much as expected and no more.

A constructor wrapper that records all calls made to it.

Call information recorded by a spy.

An instance method wrapper that records all calls made to it.

An error related to spying on a function or instance method.

Creates a session that tracks all mocks created before it's restored. If a callback is provided, it restores all mocks created within it.

Creates an async session that tracks all mocks created before the promise resolves.

Creates a function that resolves the awaited iterable values. Any awaited iterable values that are errors will be thrown.

Restores all mocks registered in the current session that have not already been restored. If an id is provided, it will restore all mocks registered in the session associed with that id that have not already been restored.

Creates a function that returns one of its arguments.

Creates a function that returns its arguments or a subset of them. If end is specified, it will return arguments up to but not including the end.

Creates a function that returns the iterable values. Any iterable values that are errors will be thrown.

Creates a function that returns the instance the method was called on.

A function or instance method wrapper that records all calls made to it.

Wraps a function or instance method with a Spy.

Call information recorded by a spy.

An instance method replacement that records all calls made to it.

Replaces an instance method with a Stub.

Make an assertion that actual matches a snapshot. If the snapshot and actual do not a match, then throw.

Default serializer for assertSnapshot.

Overrides the real Date object and timer functions with fake ones that can be controlled through the fake time instance.

An error related to faking time.

Asserts at compile time that the provided type argument's type resolves to the expected boolean literal type.

Asserts at compile time that the provided type argument's type resolves to false.

Asserts at compile time that the provided type argument's type resolves to true.

Asserts at compile time that the provided type argument's type resolves to the expected boolean literal type.

Checks if type T has the specified type U.

Checks if type T is the any type.

Checks if type T exactly matches type U.

Checks if type T is the never type.

Checks if type T is possibly null or undefined.

Checks if type T is the unknown type.

Checks if type T does not have the specified type U.
