A matcher framework for Swift and Objective-C that provides an expressive syntax for writing test expectations.
Nimble is a matcher framework for Swift and Objective-C that provides an expressive syntax for writing test expectations. It allows developers to write clear, readable assertions in unit tests, such as checking equality, containment, or asynchronous conditions. The framework is designed to integrate with XCTest and other testing tools, improving test maintainability and developer productivity.
Swift and Objective-C developers writing unit tests for iOS, macOS, tvOS, or watchOS applications, particularly those using XCTest or the Quick BDD framework.
Developers choose Nimble for its fluent, natural language-like API that makes test assertions more readable and expressive compared to raw XCTest assertions. Its rich set of matchers and seamless integration with Quick provide a superior testing experience for Apple platform development.
A Matcher Framework for Swift and Objective-C
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Uses a natural language-like API such as `expect(value).to(equal(2))`, making test assertions more readable and intention-revealing compared to raw XCTest.
Includes a wide variety of built-in matchers for equality, comparison, containment, and asynchronous conditions, reducing the need for custom assertion code.
Fully compatible with both Swift and Objective-C, allowing seamless testing in mixed codebases or legacy projects without switching frameworks.
Provides matchers like `toEventually` for easily testing asynchronous operations and time-dependent behavior without manual polling or complex setup.
When installed via Swift Package Manager, the raiseException matcher is not available, hindering testing of exception-throwing code in certain setups.
Supports multiple installation methods (SPM, CocoaPods, Carthage, submodules), which can lead to confusion or inconsistency in team environments compared to XCTest's built-in nature.
Adds an external framework dependency to the test suite, increasing project complexity and maintenance compared to using only XCTest.
