AW: [geclipse-dev] Quality metrics
|
HI all
I propose to start with the implementations of the system to measure the metrics.
We need the measurements soon. If we do NOT adress quality with metrics in the first year report,
We will run in problems at the review.
So be pragmatic, start with the implementation of the first metrics. And then we will enhance the
System step by step.

>>Dear all,

>>As mentioned in the audio meeting this afternoon, I give you a brief

>>of novel ones.
>>
>>1. Size: code size (statements, blank, comments, executable), method
>>size (number of lines) (! 30% of comments is regarded as efficient)
>>2. Class: number of methods (two large means many children and high
>>inheritance-->prevent reuse)
>>3. Messages: number of methods which can be invoked in response to a
>>message (measuring complexity)
>>4. Cohesion: is defined as the degree that methods in a class are
>>related to one another. It is measured with "how methods use the same
>>data field in a class"
>>5. Coupling: measured by "number of classes on which a class depends"
>>6. Inheritance: measured by "number of ancestors and children of a
>>class"
>>
>>Cheers,
