A bug-free system is still a failure if it does not meet user needs. 🛠️ Techniques & Strategies Software Testing Techniques and Strategies - IJERA The approach for an e-commerce site differs significantly

Static testing involves verification without executing the code. It is often the most cost-effective way to catch errors early. It is often the most cost-effective way to

The most fundamental principle is that testing can prove that defects exist, but it can never prove that defects are absent. Even if a system passes a thousand test cases, it does not guarantee perfection; it only increases confidence in the system. Testing reduces the probability of undiscovered defects but cannot guarantee zero defects.

Before one can apply a technique or operate a tool, the mindset must be shaped by core principles. These axioms, refined over decades of practice, prevent common fallacies and guide efficient resource allocation.
