substack/tape

Features

• TAP Stream Outputs - Outputs test results in the standardized Test Anything Protocol (TAP) format.
• JavaScript Testing Frameworks - Implements a comprehensive framework for writing and running automated tests within JavaScript environments.
• Exception Validation - Includes specialized assertions to verify that function calls throw expected exceptions and match specific error patterns.
• Async Operation Coordinators - Coordinates the completion of asynchronous tests by tracking pending assertions.
• Cross-Environment Test Harnesses - Acts as a unified harness for executing a single test suite across both server-side and client-side JavaScript runtimes.
• TAP-Format Harnesses - Implements the Test Anything Protocol (TAP) to provide a standardized, machine-readable format for test results.
• Cross-Environment Test Execution - Enables the same test suites to be executed across both server-side and client-side environments.
• Test Result Reporters - Generates standardized test result reports using the TAP protocol for machine-readable consumption.
• Asynchronous Test Handling - Manages synchronization of asynchronous operations to ensure they complete before finishing tests.
• JavaScript Assertion Libraries - Provides a robust set of assertion tools for validating value equality, truthiness, and exception handling.
• Node.js Test Automation - Serves as a dedicated test runner tailored for automating tests within the Node.js runtime.
• Test Case Definitions - Enables the creation of named test cases with options for timeouts and skipping.
• Asynchronous Assertions - Supports asynchronous assertions that coordinate the order of execution and wait for non-blocking operations to complete.
• Value Equality Assertions - Provides a variety of comparison methods to validate truthiness, equality, and structural equivalence.
• CLI Test Runners - Provides a command-line interface for discovering and executing automated test suites.
• Unit Testing - Provides a framework for writing unit tests to verify the smallest pieces of JavaScript logic in isolation.
• Cross-Platform Test Execution - Enables the same test suites to be executed across both Node.js server-side and web browser environments.
• Stream Redirection - Allows routing test output to custom writeable streams instead of the console.
• Test Environment Preloading - Supports injecting configuration scripts into the global scope before executing tests.
• Test Output Streams - Generates readable TAP or object streams to bypass default console output.
• Property Access Spies - Provides spies to monitor and log get and set operations on object properties.
• CI Test Execution - Ensures full test suite execution and passage as a prerequisite for deployment within automated pipelines.
• Function Call Tracking - Includes utilities for recording function invocations, arguments, and return values as spies.
• Test Lifecycle Hooks - Provides mechanisms for executing setup and teardown logic after tests finish or when failures occur.
• Test Execution Filtering - Provides mechanisms to exclude specific test files or folders using command-line patterns.
• Test File Discovery - Automatically identifies and discovers test files using filesystem glob patterns.
• Module Preloading Hooks - Allows preloading specified modules into the environment to establish global configurations.
• Test Producers - A lightweight test harness for Node.js and browser environments.
• أطر عمل الاختبار - TAP-generating test suite for Node and browsers.
