Daedalos JUnitExtensions JUnit The djux JUnitExtensions make it possible to define test resources as known from the Smalltalk SUnit. Unit tests are speeded up by using test resources, because time-consuming initializations are only done once and remain active over a series of tests. As an example, a database connection is opened before executing the first unit test and can be accessed during the whole testing circle. It isn't necessary to re-open the database connection before an unit test is executed
DbUnit JUnit DbUnit is a JUnit extension (also usable with Ant) targeted for database-driven projects that, among other things, puts your database into a known state between test runs.

TurboData Yes Canam Software TurboData was devised by a developer who wrote a small batch program to manipulate data on a few tables. He found it took longer to create the test data to test his program than to write the code. It was so time consuming making sure that the data was the correct format and all the foreign keys were resolved. He then proceeded to write an automated test data generator that would just populate every row of data on every table with default data values to make sure that the foreign keys would be the same as the parent identifier.

Software Company's checklist for testing their Software.are the followings:

We can help you and can provide consultancy if we know the following questions such as company size, software type, budget, resource available, and the time span. We need to know the type of the software; if the software were safety critical then it would need additional testing. More testing causes more budgets of course. Another important things are, what’s the software development methodology you have used for design and develop your software.

We can apply the test-driven development is one of the central techniques of Extreme Programming. In TDD, we write tests not as an afterthought to ensure the software works, but instead as just part of the everyday, every-minute way of building software. Instead of writing detailed design specifications on paper, we write them in code. Instead of first striving to completely design a system on paper, we use tests to lead our design. In this software development and testing method instead of coding for hours at a stretch, only to find our planning went awry, we use test-first design to pace ourselves, always assuring that we are building high quality software with each passing minute.

We have created the new software development method, Testing Before Coding (TBC). Unlike Test-driven Development or waterfall or spiral method it does require any prior experience for developing software. The main difference between Testing Before Coding and TDD is in the development or coding phase. In the TBC method, the developers does not write program or does not create unit test cases before writing code. However, the software developers create functional black-box test cases before writing code following software requirements, software data specification, and software data modeling.

In the TBC method, the software developers write code and execute the test cases make sure that all test cases passed otherwise they would generate more similar test cases, fix the code and run the whole test suite again. Developers make sure that the recent changes did not break the program somewhere else or create new faults or failures in the software. In general the TDD method apply the unit testing or white-box testing. On the other hand, the TBC method applies functional black-box testing primarily; however, software developers also perform similar testing like white-box testing without writing the test cases before like TDD. Software developers go back to the code, refactor, or modify the code to fix the problem. Most frequently they follow the code walkthrough methods. Other researcher proved that the code walkthrough method is an effective tool in the areas of quality assurance and software education
