Why is Software Testing important?

Personally, I think Programming Testing is important since, in such a case that there are any bugs or blunders in the product, it very well may be recognized early and can be tackled before the conveyance of the product item. Appropriately tested programming items guarantee dependability, security, and superior quality which further results in efficiency and cost-adequacy, and consumer loyalty.

Does anyone have any more opinions on important implementations in software testing?
