ThrowTheSwitch/Unity
Unity
Unity 是一个用于 C 语言的轻量级单元测试框架，提供了验证代码正确性所需的断言库、测试运行器和报告机制。它作为在 C 环境中组织和执行单元测试的核心测试基础设施。
该框架专为系统级和嵌入式软件验证而设计，具有验证固件和硬件驱动程序的特定功能。它专注于内存完整性和指针有效性，允许验证指针状态并检查原始内存块。
该工具集涵盖了广泛的比较类型，包括针对整数、位模式和浮点值的数值验证。它还提供用于验证以空字符结尾的字符串、数组内容和布尔逻辑的实用程序，同时支持自定义失败消息以在调试期间提供上下文。
Features
- C++ Unit Testing - Provides a lightweight framework for writing and running unit tests for C functions.
- Assertion Macros - Uses assertion macros to capture file and line metadata during test failures.
- C Assertion Libraries - Ships a collection of macros for comparing integers, strings, and memory blocks with descriptive failure messages.
- Embedded Software Validation - Verifies the correctness of firmware and hardware drivers by testing memory blocks and bit patterns.
- Embedded Test Runners - Provides a minimal test runner that can be integrated into C binaries to execute unit tests.
- Unit Testing Frameworks - Provides a lightweight library for verifying C code correctness through assertion macros and failure reports.
- Data Comparison - Performs raw byte-by-byte comparisons of memory segments for non-convertible data types.
- Epsilon-Based Type Comparators - Provides epsilon-based comparisons to handle floating-point precision errors during test assertions.
- Memory Integrity Testing - Checks for null pointers and compares raw memory segments to ensure data integrity.
- Bit Status Checkers - Checks if specific bits or masked ranges in an integer are set to verify hardware flags.
- Null Value Validation - Verifies whether a memory pointer is null or non-null to ensure reference validity.
- Array Content Verifications - Compares multiple array elements against another array or a single expected value.
- Binary Memory Comparisons - Performs raw binary equality checks between memory blocks to validate complex data structures.
- Bit Pattern Verifications - Provides macros to verify the state of hardware flags or packed integers using bitmask-based inspections.
- Conditional Logic Evaluation - Evaluates boolean conditions and marks tests as failures if results differ from expected truth values.
- Boolean Logic Assertions - Implements logic to evaluate expressions and trigger test failures when actual boolean results deviate from expectations.
- Floating Point Comparisons - Provides epsilon-based floating point comparisons to verify numerical correctness in unit tests.
- Assertion Message Customizers - Allows users to append descriptive context to assertion failures for improved debugging.
- Integer Comparisons - Provides assertion macros to check equality and threshold requirements for integer values.
- Null-Terminated String Verifications - Compares character sequences by iterating through memory until a null terminator or length limit is reached.
- String Comparisons - Verifies that null-terminated strings are identical or match for a specific character count.
