What-are-benefits-or-advantages-of-automated-testing?

 

Following are the benefits for using automated tools

Fast:

Human be slow but Automated Testing Tool runs tests significantly faster than human users.

Reliable:

Tests perform precisely the same operations each time they are run, thereby eliminating human error.

Repeatable:

You can test how the software reacts under repeated execution of the same operations.

Programmable:

You can program sophisticated tests that bring out hidden information from the application.

Reusability:

You can reuse the Automated Test scripts, user defined functions etc.

what are quality attributes and quality factors?

There are three types of quality attributes:

1. Product Operations
2. Product Revision
3. Product Transition

Quality factors are related to attributes which are:


1.Product Operations:

• Correctness: does it do what i want?

Operation are correct and according to requirement.

• Reliability: does it do accurately all the time?

The operations performed, are all the time correct and mean if now is 1+2=3 all the time it should be 3.

• Efficiency: will it run on my machine as well as it can?

My program is efficient and it runs in same on all machines

• Integrity: is it secure?

My software is secure and it is not accessible to spamers

• Usability: can i run it?

My software is easy to use or user friendly.

2.Product Revision:

• Maintainability: can i fix it?

Software can maintained easily.

• Flexibility: can i change it?

When needed can be changed.

• Testability: can i test it?

We can test it as it developed

3.Product Transition:

• Portability: will i be able to use on another machine?

It means that our software can be run on windows as well as linux or per required

• Reusability:will i be able to reuse some of the software?

If we have developed a software then its components are reuse able can adjusted to other software or separately if needed.

• Interoperability: will i be able to interface it with another machine?

for example my software is running on windows, then can i work with system which is running on linux etc
