Unit testing is essential for businesses for several reasons:
1. Cost-Efficiency: Identifying and fixing bugs early in the development cycle saves a significant amount of money and resources compared to fixing them in later stages. 2. Quality Assurance: Ensures that each module of the software performs as expected, contributing to the overall quality of the application. 3. Risk Management: Mitigates risks by ensuring that critical functionalities are tested and validated before deployment. 4. Regulatory Compliance: For industries like finance and healthcare, unit testing helps in maintaining compliance with industry standards and regulations.
