In 2002, we, the Macau productiveness and know-how heart (CPTTM), began to carry classes on XP and item orientated layout to educate the abilities by way of hiring a well-known software program education and consulting corporation to do the instructing. whereas the trainer was once very expert and instructive and the scholars have been chuffed, they did not gather the abilities taught.
We knew that it used to be as the innovations concerned have been summary and it wanted way more routines for the scholars to perform within the classes. for that reason, we made up our minds to advance our personal education fabrics. particularly, we chosen the 20% of the talents in agile improvement that convey eighty% of the worth, ignoring the opposite invaluable yet non-essential talents. Then we defined these crucial talents when it comes to examples and additional loads of actual international examples as routines. After adopting this set of fabrics, the scholars rather got the abilities taught.
In order to percentage this with the neighborhood, we now have equipped the learning fabrics into this publication: crucial abilities for Agile Development.
The ebook comprises the subsequent chapters: (1) removal reproduction code. (2) Turning reviews into code. (3) elimination code smells. (4) conserving code healthy. (5) Take care to inherit. (6) dealing with beside the point references. (7) Separate database, person interface and area good judgment. (8) coping with software program tasks with person tales. (9) OO layout with CRC playing cards. (10) popularity attempt. (11) tips to attractiveness attempt a person interface. (12) Unit try. (13) try pushed improvement. (14) crew improvement with CVS.

Therefore, whenever we find code smells in the code, we must become alerted and check the code carefully. Now, let's see the code smells in the example code above. Code smells in the example code The first code smell: The code uses type code: class Shape { final int TYPELINE = 0; final int TYPERECTANGLE = 1; final int TYPECIRCLE = 2; int shapeType; ... } This is a severe warning that our code may have problems. The second code smell: The Shape class contains variables that are not always used. For example, the variable radius is used only when the Shape is a circle: class Shape { ...
