Explore the comprehensive landscape of unit testing packages available in the Julia programming language ecosystem through this 27-minute conference talk from JuliaCon Global 2025. Discover how Julia's testing tools reflect the community's focus on scientific computation and leverage the language's unique ability to combine numerical methods with symbolic approaches. Learn about nine distinct categories of testing packages available on JuliaHub, including unit test frameworks, test set extensions, mocking and faking tools, property-based testing, mutation testing, test code coverage analysis, regression testing, floating-point assessment, and performance testing. Gain insights into which packages are popular versus overlooked in the community, and understand how these powerful testing tools can save development time by helping identify difficult bugs in critical software. Use this knowledge to make informed decisions about unit testing strategies for your next critical Julia code project.
