Black box test automation tool refers to a testing used when knowledge is inadequate or the source code cannot be accessed. Black box testing software engineering has a few advantages as well as disadvantages. Check additional information about black box test automation tool.

Black box test automation happens when software is tested based on output conditions and when the user is clueless about the structure and coding of the program.

Also known as Functional/Behavioral Testing and Closed Box Testing, the black box test automation tool is a strategy for choosing the right data for each functionality, and testing to see the common and uncommon performance of the system.

The testing should be done by a third party because the fact that the programmer knows the coding of the system disqualifies him from objective testing of the program.

The tester need to be careful in the needed specifications of the system and should be equipped with knowledge on how the system should react to specific acts.

There are advantages and disadvantages that come with black box test automation tool. An advantage of the black box test automation is that the tester will do what the user does. Whatever the user will click or work with, the tester will also be using it, making black box testing a testing that is done from a user's perspective.

Meanwhile a common disadvantage of the black box testing is the difficulty the tester will encounter in automating it. As opposed to unit or functional tests which is quick to complete, black box testing entails the tester to use software graphical interface [GUI].

To be able to do a black box testing for software, there are three ways. The first way is through manual testing which should be done by programmers. This usually cost a lot.

The second way is through record and playback testing. Once the programmer has done testing and recorded the process which involves the mouse, buttons and entering text, the actual test application will then be measured against the recorded test and the results of the two tests will be compared.

The third way towards black box testing automation is through automation testing. Apart from recording the actions of the mouse, it also enables the script to imitate the actions of the user. Automation testing is then more adaptable as it not only enables the pointing of the mouse but allows spotting and focusing on an image as well.

Test automation costs are usually computed as the sum of test development expenses, test using expenses and test maintenance expenses. The test development expense will be based on the software used for producing automation testing scripts. Meanwhile the automated test expenses will require a second computer or separate time on your computer and will only take few minutes to test and evaluate. The maintenance expenses will be considerably cheaper than the record and playback testing as it just needs modification for some images and not the whole testing process.

There are various test design methods for black box testing. These are boundary value analysis, decision table testing, equivalence partitioning, pairwise testing, and state transition tables.

Black box test automation tool can be used for software testing which includes unit, integration, functional, system, and acceptance. Almost all higher levels are covered by black box testing, and may also be used for covering unit testing.
