AUTOMATED SOFTWARE TESTING

ADVANCED SOFTWARE ENGINEERING CSC 532Presented by VISHAL D RAMPURE

INTRODUCTIONINTRODUCTION

Software testing is analyzing a system or a Software testing is analyzing a system or a component by providing defined inputs and component by providing defined inputs and comparing them with the desired outputs to comparing them with the desired outputs to check the discrepancies between the desired check the discrepancies between the desired and actual outputs and correct themand actual outputs and correct them

TEST TYPESTEST TYPES

Software testing can be divided into Software testing can be divided into two categories.two categories.

Manual testingManual testing

Automated software testingAutomated software testing

AUTOMATED SOFTWARE TESTINGAUTOMATED SOFTWARE TESTING

Automated testing programs will not miss a Automated testing programs will not miss a test by mistake. test by mistake.

The automated test program will also provide The automated test program will also provide a means of storing the results of the tests a means of storing the results of the tests accurately. accurately.

The results can be automatically fed into a The results can be automatically fed into a database and can be used to provide useful database and can be used to provide useful statistics on how the software development statistics on how the software development process is progressing.process is progressing.

overhead.overhead. As more automated tests are added to the test As more automated tests are added to the test

suite more tests can be run each time suite more tests can be run each time thereafter. thereafter.

Manual testing never goes away, Manual testing never goes away, The efforts that were used for manual testing The efforts that were used for manual testing

can now be focused on more rigorous tests. can now be focused on more rigorous tests.

CONSCONS Costs of test automation include personnel to Costs of test automation include personnel to

support test automation for the long term. support test automation for the long term. A dedicated test environment is needed A dedicated test environment is needed The cost for the purchase of development and The cost for the purchase of development and

maintenance of tools. maintenance of tools. If contractors are used to help build or If contractors are used to help build or

champion the test automation effort because of champion the test automation effort because of their experience, there is the risk that much of their experience, there is the risk that much of the experience and skills will not be there when the experience and skills will not be there when the contractor leaves. the contractor leaves.

If there is going to be a product change then If there is going to be a product change then long term automation is a waste long term automation is a waste

It is very expensive to maintain automated It is very expensive to maintain automated testing environment.testing environment.

CONCLUSIONCONCLUSION

Automation of software testing is not an Automation of software testing is not an easy process. easy process.

It involves a lot effort. Automation is also a It involves a lot effort. Automation is also a expensive process in terms of direct expensive process in terms of direct finance and the people required for. finance and the people required for.

We can conclude that if automation is dine We can conclude that if automation is dine in very definitive manner and with all in very definitive manner and with all aspects considered it can be asset to the aspects considered it can be asset to the companycompany..
