Advantages of using testing tools:-

1- Decreasing of recurrent work:- When we done recurrent work manually then it is feeling very bore. There is more possibility to make mistakes when doing the same work again and again. There are many examples of this type of recurrent work like executing regression tests, using same test data frequently (This action can be also performed by test execution tool), verifying across the coding principles (Which can be performed by a static analysis tool).

2- Better regularity and repetition:- There may be create a little bit of difference on the same work when people do again and again. They think that they are repeating exactly but there is a slightly different as previous. But when we use any testing tool than tool can reproduce same as it did before, so in all time result is consistent when we use any testing tool to run.

3- Objective evaluation:- When any people estimates any value by using any software or application, by fault they may ignore anything, or their own one-sided planned decisions may control them to translate that evidence wrongly. Using any testing tool means that subjective prejudiced idea is eliminated and the evaluation is more repeatable and regularly calculated. For examples coverage (coverage measurement tool), system behavior (monitoring tools) and incident statistics (test management tool).

4- Reduce of access to information about testing:- Instructions delivered visually is much comfort for the human mind to learn and explain. For exp, to represent any information by using chart and graph is a good way in place of a long list of numbers, this is why graphs and charts are very useful or helpful in the spreadsheets.
