Introduction to Adapters
• We may have an application that needs to use libraries/a different application/you-name-it, but the thing we want to call has a different interface than our caller.  Alternative 1: Re-write the caller o Ugly, messy, error-prone (Equivalent to changing the power cable in our electrical plug when we go abroad)

 Alternative 2: Re-write the called libraries/classes o May not have the source code o As ugly and error-prone as Alternative 1

 Alternative 3: Write an adapter  The adapter converts all requests to a language the adaptee understands See http://mypages.valdosta.edu/dgibson/courses/cs4322/Lessons/Adap ter/AdapterNotes.pdf

Another example
Client class programmed against a Vendor class. Thus, the Client is strongly coupled with the Vendor class.

Later, it is decided to change vendors. Vendor2 is selected which has different method names.

Example (cont’d)
The Client must be modified in order to adapt to the new vendor.  What was the problem? The Client class encapsulates some portion of application logic, which is intertwined with the Vendor class.  This causes the strong coupling/ dependence. Thus, modifying the Client code to adapt to the new vendor could result in errors being injected into the application logic.  How do we mitigate this situation where we have a Client coded against a Vendor, where the Vendor will change?

Two helpful design principles
• Identify the aspects of your application that vary and separate them from what stays the same. • Program to an interface, not an implementation. • The first principle suggests that we separate the application logic from the code tied to the vendor. • The second design principle indicates how we may achieve that. • We program against an abstraction of all Vendor classes and then use an Adapter to encapsulate vendor specific code required to implement…...

...Non-Functional Testing and Security Testing in Mobile Application Development Abstract Smart-phones have become part of human life. As smartphones become more powerful and usage rises, Smartphone makers have a much wider range of innovation possibilities than their PC counterparts. The personal nature and pocket size of mobile phones and their potential offer a wide scope for developing distinctive handset models targeted at a specific segment of the smart-phone market. The mobile application market’s growth is driven by the widespread push of advanced handset capabilities by the mobile industry and the increasingly-connected global consumer base. Progress of network technologies, restructuring of revenue-sharing pattern, lowering of mobile data usage cost, growing adoption of smart phones, and increase in application usability have contributed to the growth of mobile application adoption globally. This trend has led to substantial surge in the dependence and usage of the mobile Internet, specifically mobile applications. Mobile Application Development is the method by which application software is produced for low power handling devices, mobile devices, and other small digital equipment. As this technological development continues to gain momentum, it's quickly turning into one of the most powerful industries in the world. Majority of the mobile application testers tend to focus more on testing the product against client requirements – Functional testing and pay......

...Testing. Source from others KANSAS CITY ZEPHYRS BASEBALL CLUB: A BASEBALL ACCOUNTING DISPUTE This case is used to illustrate some basic accounting issues in a controversial setting. The controversy arose because the baseball team owners and the players association were engaged in collective bargaining negotiations and the outcome of those negotiations depended on the parties’ agreeing on the true profitability of the baseball business. The case describes 3 areas in which the accounting is being disputed: Roster depreciation; Player compensation; Transfer pricing of related party operations (stadium costs); 1. Roster Depreciation The owners recognize depreciation of a value placed on the player roster at the time the baseball club was purchased apparently just because tax rules allowed them to do so. Tax rules allow this value to be set arbitrarily at a maximum of 50% of the purchase price (It would be foolish to set it at a lower value for tax purposes). The depreciation is spread linearly over six years and comes to $2m per year. The players do not feel that any roster depreciation should be shown: if anything, they argue, the roster appreciates as the players become more experienced. The economic truth is that player rosters - baseball clubs’ most valuable assets - appreciate and depreciate over time: good scouting, trades, and coaching increase the roster value. In contrast, injuries and retirements decrease it. The roaster should hence......

...stress it allows for the mental health/behavioral health practitioner to effectively assess the progression of the treatment being used on the patient. Though the DASS can be used in an occupational setting, it can be detrimental to an individuals career path due to an employer having record of an individuals mental health on file which could cause an individual to lose their job due to an employer viewing an individual as being a risk. Though the DASS can have negative impact on an individual career, it can also be beneficial as well especially if the profession that it is being used in is a high stress job. Jobs such as those found in the various branches of the military or other government positions may require an individual to go through testing of their mental health so as to assess whether or not the individual would be capable of effectively performing their duties since an individual whom has high levels of depression, anxiety, and/or stress can prove to be hazards on the job. In an academic setting, the DASS can be effective when used with children so as to be able to see if a child is capable of handling the requirements of their educational course or if they should be given extra attention so as to better absorb the materials in which they are to learn....

...designer of the Concordion Extensions API. The Concordion tool is available for free at concordion.org/Download.html. 2. What testing purpose does the tool serve? (i.e., what problem does it attempt to solve? How does it improve productivity?) Concordion is an open source tool that is used for the automation of Specification by Example. Using simple HTML, developers can create concrete examples in any specifications with certain commands. This allows for Concordion to check the examples against a real-life system. The specifications allow for complete cover of any behavior important to a customer. Based on this, specifications can be used as unit tests. Concordion specifications are also clear and readable so they can also serve as system documentation. This means a project’s specifications can be easy to understand for the development team, as well as anyone outside it. This would ultimately allow for a better maintenance of software quality as the software can be reviewed as a group effort. 5. What do you need to do in order to use the tool? There is ample documentation provided on the Concordion website to guide you through the install and configuration process. Concordion requires JDK5.0 and the following JARs in the classpath: • concordion-1.4.7.jar • junit-4.12.jar (or junit-3.8.2.jar) • hamcrest-core-1.3.jar (required for JUnit 4.11 or later) • ognl-2.6.9.jar • xom-1.2.5.jar These are all included in the download that Concordion provides.
