Testing: It denotes an activity to check whether actual results match expected results. It guarantees that software system is defect free. It involves execution of a software component for evaluating one or more interest properties. It identifies errors, gaps or requirements that are omitted related to actual requirements. It could be performed manually or using automated tools. It can be classified as white or black box testing. The manual testing would include testing of software short of any tool. The tester behaves as an end-user. It tests software for identifying any behavior that is unexpected. The different stages include unit, integration, system as well as user acceptance testing. The automation testing uses software to test product. It includes automation for a manual process. The test scenarios are been re-run that are been performed manually. It is used for testing application from performance, load in addition to stress view point. Driver program : The driver program contains program’s main function. It is responsible for launching program operations. It is responsible for converting user program into physical execution unit termed as task. Each function must be designed, tested and coded as a discrete unit from rest of program. It denotes a testing program for functions or statement that is been written in code. It tests the functionality usually for debugging as well as code verification. Given addTax function: //Define method addTax void addTax(double taxRate, double& cost) { //Compute cost cost = cost + ( taxRate/100.0 ) * cost; } Explanation: The method “addTax()” takes input values as arguments. It computes the cost by using input values entered by user. The result of operation is been displayed.

Dijkstra's Algorithm (part 1). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values. Write down your final [correct] answer, as you‘ll need it for the next question.
