Automated Testing: Guarantee of the Quality

Feb. 20, 2013 - PRLog -- <p>What do you know about <b>automated  testing</b>? Lets try to give a short definition: Automated testing is the use  of special software to control the execution of tests and the comparison of  actual outcomes to predicted outcomes. It is the most appropriate type of  testing when a product changes often, but has large functionality. This kind of <b>software testing</b> is usually focusing  on creating a set of running tests to cover the newest and the most critical aspects  of the developed software.</p>

<p>The aim of this kind of testing is the discovery of errors in software.  It means that the quality of software can be developed even before the official  release of the product. </p>

<p>But there can be different obstacles because of which it is impossible  to perform high-quality <b>automated  testing</b>. E.g.: If the error occurred in the first 10% of the tested  software, then it will be impossible check the rest. Not only quality will  suffer because of it, but also the budget, there will be also needed more time  to eliminate errors and to continue the rest of the test, find new errors and  resolve them. </p>

<p>Testing is not as easy as it seems to be. The process of testing and development  should be well thought-out. Only in such case errors can be evaded. </p>

<p>What types of errors can occur while performing test automation? It is  very difficult to define them as every case is unique and requires different  ways of solving the problem. Moreover errors are the reflection of the  difference between the expected state and behavior in software and actual state  and behavior. So you can never know what errors can occur in the system.</p>

<p>Expected results are usually compared with the result of the testing. Only  in such way it is possible to see all errors obviously. </p>

<h2>The most common errors which can occur during the process of <b>automated testing</b>:</h2>

<ul>

 <li>Actual error  which is found while performing testing;</li>

 <li>Error in test specification  such as logical mistake in the test and some kind of misunderstanding between  development and testing teams;</li>

 <li>Error in test  environment such as wrong path, database errors, errors arising from other  programs.</li>

</ul>

<p>But problems can be more easily evaded if<b><a href="http://qatestlab.com/company/why-software-testing/"> software testing </a></b>is performed by <b><a href="http://qatestlab.com/">software testing company</a></b>. Still it is necessary to be prepared to  some unexpected events that can be a challenge while performing <b>automated testing</b>. This kind of testing  is easy and not difficult to maintain. It verifies the state of software being  tested for aspects of function significant to the user and to software itself.</p>
