Topic: Test case generating tool in detail

RBT tool generally make graphs to generate test cases.

Only liscenced person will get this tool.

Well, its good to know about test case generation tool.... also I would like to suggest you to new test management tool named Zephyr, it helps to you organize neatly all test cases assigned for you and also links to software and sites under test are provided.

Please also consider the Hexawise test case generating tool at http://www.hexawise.com/users/new.  We have a free version and a 30-second login process for full access.  Many users are giving us enthusiastic feedback about how easy it is to use, how quickly they are able to put together their test plans, and how many defects they are now finding that their prior manual methods of test case selection would have missed.

Unlike most test design tools, Hexawise offers:

1) Not only pairwise (AKA 2-way) solutions, but also it creates 3-way, 4-way, 5-way, and even 6-way solutions.  (In other words, you can choose the level of thoroughness you desire, and Hexawise will generate the test conditions you should execute to achieve maximum coverage with the fewest possible number of tests).

2) Clear graphs showing the coverage that your test plan is generating (e.g., you will be able to tell that after test #26, for example, you have tested for a specific percentage of the total number of possible pairs of values that you have indicated you want to test for

3) Example plans that help get you started using a test design tool

4) Clear FAQ and Help sections to address any questions you might have (see http://www.hexawise.com/faq and http://www.hexawise.com/help

5) The ability to identify certain combinations of values as invalid.  (Once testers begin using test design tools, they recognize that this feature is extremely important; if Parameter values include "Annual Income" = US$5,000 and "Mortgage Type" = Jumbo, for example, but a user of a mortgage application with that income would be unable to even select the option to apply for a Jumbo mortgage, if your test design tool does not allow you to eliminate those invalid combinations automatically, you will either (a) wind up with lost coverage that you had hoped your tool would be able to deliver, (b) spend many hours trying to address this shortfall by manual adjustments to your test cases, or (c) both.

Lastly, we currently have an 11-slide presentation on our home page to quickly provide a little more background information about the tool and the problems it solves with screen shots.  It also contains an interesting case study of how Hexawise can help you reduce 72 billion possible test cases (that would be required -at least - to comprehensively test the "get directions" functionality of Google Maps) to only 35 test cases that achieve coverage of every single valid pair of parameter values involved.  (e.g., in those 35 test cases, every single browser type is tested together with every mode of transportation choice at least once, every single view option is tested together with every option for the zoom/in zoom/out function, etc.)

Thank you.

cool7575,

I recently co-authored a paper with 3 PhD's on this topic, here: 

http://csrc.nist.gov/groups/SNS/acts/documents/kuhn-kacker-lei-hunter09.pdf

The data clearly shows that you can rely on test case generators like Hexawise to generate test cases for you (e.g., if you input the variables that should be included in testing, the tools will identify exactly what should be tested when in each test case - but admittedly this stops short of using them to figure out "Expected Results" for you). Those testing teams that adopted this approach found more than two times as many defects per tester hour than those teams that used manual test case identification methods.

Seeing whether a test case generator identifies better test cases to generate than a person would identify manually is very straightforward; give one small team access to a tool like Hexawise (freely available at http://www.hexawise.com/users/new) and have another team test the same application without using Hexawise.  Dozens of proof of concept pilots show there are dramatic improvements to both efficiency and effectiveness.  But don't take my word for it, just give it a try and count the number of defects found by the small team that uses Hexawise as compared to the small team that uses manual test case selection methods.

Free access to the Hexawise test case generator is available at http://www.hexawise.com/users/new
(We will charge for a commercial version of the tool after adding additonal features)
