Why Testing is important.....

Testing is about verifying that what was specified; what was delivered. In simple word software testing is activity to check whether the actual results match the expected result. It is very important to understand that testing is also continuous process .Testing does not stand alone it is intimately dependant activity but it is separate process activity .Testing is the activity which can reduce the defects.

Testing is also begun from the starting phase of the SW Life cycle from the requirements. Traditionally testing is take place at end of the s/w life cycle (Waterfall model), Testing should take place through out software life cycle. If you want to cut down cost of the bug find bug as early as possible. Testing is like repeated activity testing never completed in one pass it has to be give more passes or you can more iteration. Because as you do so you generate more confident for that product.

We say best software which tested by thousands of users under various different condition. Then we can say it is good to go or “stable” but this does not mean that software is bugfree.it’s mean that bugs are well-identified and well understood.

Software bugs can potentially cause monetary or even loss of life. It can be expensive or even dangerous.
