Why does a software need to be tested? |
| |
Every software product needs to be tested since :- The development process is unable to produce defect free software.
- Even if the development process is able to produce reasonably defect free software, we will not be able to know this unless we test it.

- Testing not only identifies and reports defects but also measures the quality of the product, which helps to decide whether to release the product, or not.
