Coordinator: Phạm Tiến Phúc ATM System Page 3 Huỳnh Thủy Ngân NIIT Cần Thơ ACKNOWLEDGEMENT We have benefited a lot from the feedback and suggestions given to us by Mr. Phạm Tiến Phúc and other faculty members, and the machine room coordinator. ATM System Page 4 Huỳnh Thủy Ngân NIIT Cần Thơ SYSTEM ANALYSIS System Summary: The ATM system have following features: - Cash withdrawal - Cash deposit - Transaction summary - Changing the PIN - Check deposit - Fund transfer within the same bank On the basic of these features, prepare a white paper for testing the ATM system. The white paper should present the general requirements of an ATM system and discuss the following points: - Test environment that needs to be set up to test an ATM system. - Testing techniques that need to be adopted to test an ATM system. - Testing tools that need to be acquired to test an ATM system. - Risk involved in testing an ATM system - Typical components of a test plan that need to be developed for an ATM system. - Test metrics that need to be gathered while testing an ATM system. One of the best ways to guarantee long term performance is through rigorous, standardized testing at both the component and system levels. Testing systems check whether ATM equipment meets their design specifications, confirm that products from different manufacturers can work together, measure performance against traffic contracts, and provide assurances that the underlying physical resources are operating correctly.

The general approach in most recommended testing plans have been considered. Combined, all of them emphasize a standard approach to testing with the following steps: usability testing, unit testing, integration testing, function testing, system testing, acceptance testing and regression testing. Testing starts with the developer and the customer verifying (usability testing) the interface early in development. The developer develops the code to support the requirements and exercises it (unit test). After this, the interfaces between modules is tested (integration testing), and then independent testing against requirements (functional) is conducted. Exercising all components in a production like environment (system testing) with final testing by the customer (acceptance testing) completes most of the process. This also takes into consideration the need to retest software in the event of ongoing fixes (regression testing). Early Development of Test Cases Test cases are developed early in the process. To complement the Extreme Programming paradigm, which is discussed below, use cases will be developed early in development. These describe the use of a system by an “actor” and form the basis for both design and test cases. Extreme Programming The most common method of software development is the waterfall method, which specifies a phased approach to software development – including plan, design, code, test, and release cycles. If a project is canceled during coding or earlier, it’s probable that no working code was developed, and the entire project will yield no tangible results. ATM System Page 8 Huỳnh Thủy Ngân NIIT Cần Thơ METHODOLOGY APPROACH PROCESS OVERVIEW XP processes also include pair-up design sessions and code sessions; this ensures all code that is created is viewed by two people. After the software is created, it may be re-factored, and then tested on a single “continuous integration” machine. After copying the code, developers run a full suite of the “test first” unit tests. If the code passes all tests, the developers can check in the code and the unit test. XP unit tests and building are covered in more detail under “unit tests”, below. Essentially, stories allow coders to begin development early, and an on-site customer ensures that the software that is created actually meets the customer’s need. “Getting to the code” early transforms expenses into working software; because of the priorities, it’s possible for the customer to cancel the project at 25% of schedule and actually get working software that fulfils the most important 25% of the business need. Extreme Programming also uses the concept of “Project Velocity” to measure the cost, time, and relative late/early-ness of the project. In addition to a project-level function point analysis, Smart Savings also asked it’s developers to measure the effort involved in creating the software in Extreme Programming units (XPU). By dividing the XPUs by the typical development speed (XPU’s developed per week on previous projects) the team produced a man-month estimate for development of the ATM project; this estimate, along with function points and risk-adjusted estimates, was used to create the $350,00 bid for the ATM Project. (Note: The deviation from “book” XP of working for a fixed price was a concession to the customer made to win the contract. The customer insisted on this concession to minimize uncertainty.) The XP method practiced by Smart Savings Co. feeds directly into the testing phase of the project. Although “book” XP does not include a testing phase, this concept has not exactly been embraced by the business community. As a result, Smart Savings Co. typically includes a testing phase in it’s software projects similar to the testing phase advocated by Donaldson/Siegel in their book Successful Software Development.

Base Line The version of the source code currently in production. This is sometimes referred to as the “gold” copy of the software currently in production. Black Box Testing Testing software for its basic functionality without specifically exercising known pieces of code. Defect An instance of where the software does not meet the requirement. Function Testing Formalized testing of modules for their functionality based on the requirements document. Glass Box Testing White Box Testing Both terms are a form of testing where internal coding knowledge is used to determine testing. System Testing Formalized testing where the system is exercised under conditions similar to a regular production environment. Integration Testing Testing modules together to ensure the interfaces are compatible and meet requirements. System Testing Formalized testing where the system is exercised under conditions similar to a regular production environment. Test Case A specific set of steps to be followed to exercise a specific aspect of software. The steps include how to setup, how to provide the input and the expected output. Unit Testing Testing performed on a specific module by the developer. Use Case A story about the use of the system XP Extreme programming.
