# Equality and Inequality Assertions Check whether two values are equal or unequal. ## Topics ### Tests for Equality and Inequality [`XCTAssertEqual(_:_:_:file:line:)`](/documentation/XCTest/XCTAssertEqual(_:_:_:file:line:)) Asserts that two values are equal. [`XCTAssertNotEqual(_:_:_:file:line:)`](/documentation/XCTest/XCTAssertNotEqual(_:_:_:file:line:)) Asserts that two values are not equal. [`XCTAssertEqual`](/documentation/XCTest/XCTAssertEqual) Asserts that two expressions have the same value. [`XCTAssertEqualObjects`](/documentation/XCTest/XCTAssertEqualObjects) Asserts that two objects are equal. [`XCTAssertNotEqual`](/documentation/XCTest/XCTAssertNotEqual) Asserts that two expressions don’t have the same value. [`XCTAssertNotEqualObjects`](/documentation/XCTest/XCTAssertNotEqualObjects) Asserts that two objects aren’t equal. ### Tests for Identical Objects [`XCTAssertIdentical(_:_:_:file:line:)`](/documentation/XCTest/XCTAssertIdentical(_:_:_:file:line:)) Asserts that two values are identical. [`XCTAssertNotIdentical(_:_:_:file:line:)`](/documentation/XCTest/XCTAssertNotIdentical(_:_:_:file:line:)) Asserts that two values aren’t identical. [`XCTAssertIdentical`](/documentation/XCTest/XCTAssertIdentical) Asserts that two values are identical. [`XCTAssertNotIdentical`](/documentation/XCTest/XCTAssertNotIdentical) Asserts that two values aren’t identical. ### Tests for Equality Within a Specified Accuracy [`XCTAssertEqual(_:_:accuracy:_:file:line:)`](/documentation/XCTest/XCTAssertEqual(_:_:accuracy:_:file:line:)-6frfw) Asserts that two floating-point values are equal within a specified accuracy. [`XCTAssertEqual(_:_:accuracy:_:file:line:)`](/documentation/XCTest/XCTAssertEqual(_:_:accuracy:_:file:line:)-4epu5) Asserts that two numeric values are equal within a specified accuracy. [`XCTAssertNotEqual(_:_:accuracy:_:file:line:)`](/documentation/XCTest/XCTAssertNotEqual(_:_:accuracy:_:file:line:)-7jcd6) Asserts that two floating-point values aren’t equal within a specified accuracy. [`XCTAssertNotEqual(_:_:accuracy:_:file:line:)`](/documentation/XCTest/XCTAssertNotEqual(_:_:accuracy:_:file:line:)-326vc) Asserts that two numeric values aren’t equal within a specified accuracy. [`XCTAssertEqualWithAccuracy`](/documentation/XCTest/XCTAssertEqualWithAccuracy) Asserts that two expressions have the same value within a specified accuracy. [`XCTAssertNotEqualWithAccuracy`](/documentation/XCTest/XCTAssertNotEqualWithAccuracy) Asserts that two expressions don’t have the same value within a specified accuracy. --- Copyright © 2026 Apple Inc.
