Cuando tejes tu red de seguridad de análisis estáticos y pruebas, ¿cómo sabes que estás probando todo lo que puedes? Probar absolutamente todo es imposible; tienes que ser inteligente en las pruebas que escribes. Imagina cada prueba como una hebra separada de tu red de seguridad: cuantas más pruebas tengas, más amplia será tu red. Sin embargo, esto no significa intrínsecamente que tu red esté bien construida. Una red de seguridad con hebras deshilachadas y quebradizas es peor que no tener red de seguridad alguna; da la ilusión de seguridad y proporciona una falsa confianza.
El objetivo es reforzar tu red de seguridad para que no sea frágil. Necesitas una forma de asegurarte de que tus pruebas fallarán realmente cuando haya errores en tu código. En este capítulo, aprenderás a hacer precisamente eso con las pruebas de mutación. Aprenderás a realizar pruebas de mutación con una herramienta de Python llamada mutmut. Utilizarás las pruebas de mutación para inspeccionar la relación entre tus pruebas y el código. Por último, aprenderás sobre las herramientas de cobertura del código, la mejor forma de utilizarlas y cómo integrar mutmut con tus informes de cobertura. Aprender a hacer pruebas de mutación te dará una forma de medir la eficacia de tus pruebas.
