Logical Modelling and decision tables Logical modelling involves modelling internal structure and functionality of a process. Decision tables are useful in logical modelling. Decision tables show logic inside a process, action(s) that needs to be taken when a condition or a set of conditions are satisfied. Use of decision tables used by developers to identify any discrepancies in business rules (Tarlinder 2016).   used for customer support in telecom industry to provide an optimal plan based on the customer's usage (Singh 2015). used in SAP HANA to specify business rules (Singh 2015) Used in Model based testing as inputs  (Kramer, Legeard, Bazzana, & Binder, 2016) . B usiness rules in decision table can be converted into arguments for parameterized testing  (Tarlinder 2016).  A Decision tables can be created using the following steps: Identify conditions  Identify actions that needs to be carried out when certain condition...

What is Test Driven Development (TDD)? In TDD, the software development process begins with creating tests based on requirements. The tests are executed. At this point these tests should fail. We write code to make these tests pass. Once the test pass, we refractor the code and make it pass the test again. TDD includes at least following steps: Create test cases  Execute test cases, it should fail.  Write code to make the tests pass Refractor and make the tests pass again Test Driven Development vs. Unit Testing In Unit testing we write code and then write the test cases to test the code. Whereas in the TDD, we write the tests right at the beginning and then we write the code to make the tests pass.
