Comparing C Unit Test Frameworks

Despite previous inquiries about C unit test frameworks, there has been a lack of comparative information beyond recommendations for specific frameworks. Among the most prominent frameworks are CppUnit, Boost, and Google Test. This article delves deeper into their features and aspects.

Google Test (Google C Testing Framework)

Google Test, a relatively new entrant, offers several notable advantages:

• Portability: Compatibility with a wide range of environments
• Assertions: Provides both fatal and non-fatal assertions
• Informative Messages: Enriches assertions with helpful messages, such as: ASSERT_EQ(5, Foo(i)) << " where i = " << i;
• Automatic Test Detection: Identifies tests without explicit enumeration, simplifying testing
• Assertion Extension: Allows developers to customize assertion vocabulary
• Death Tests: Facilitates testing for expected program termination
• Subroutine Tracing: Utilizes SCOPED_TRACE for subroutine loops
• Selective Test Execution: Offers control over which tests to run
• Report Generation: Supports XML-based test report generation
• Advanced Features: Provides fixtures, mock objects, and template support

These features make Google Test a formidable option for unit testing in C .
