CMS Assessment Model - Information - Avoid Too Many Copy Pasted Artifacts

Definition

This metric measures the ratio between the number of duplicated, copy/pasted artifacts and the total number of artifacts.
Copy / Paste detection is based on statistical detection methods. The statistical methods used compute a similarity metric between all artifacts. Artifacts are reported as copy / pasted when the similarity is higher than 90% (see metric parameter SIMILARITY).
Like any statistical method, the detection algorithms require a well sized sample in order to provide significant results: testing these algorithms with a couple of classes will not do the job, a real life application’s source code is required to yield usable results. The minimal size required stands at around 5000 lines of code.
Below such a size, the algorithms detect the full list of exact copies for the copy/paste code detection but slightly modified copy/paste code will not always be detected.
Also, for optimal efficiency, the copy/pasted code detection is enabled only for artifacts larger than 10 lines of code (methods, functions, procedures, triggers, programs…).

CMS Assessment Model - Information - CAST Enforce Object Oriented Metrics - Chidamber and Kemerer Metrics Suite

Mon, 01 Jan 0001 00:00:00 +0000

Purpose

Introduction

Object-Oriented programming design and development methods have been widely adopted in the software industry. This has created a strong need for assessing the quality of OO software systems. In deed, just as Object-Oriented programming requires a different approach compared to traditional imperative programming, software metrics must differ from traditional software metrics.
The most widely known and used set of Object Oriented metrics is the Chidamber and Kemerer Metrics Suite (also called CK Metrics Suite).
The Chidamber and Kemerer Object-Oriented metrics aim to measure design and code quality by investigating the coupling among classes, the cohesion within classes, complexity of classes and the complexity of the inheritance hierarchy.
The CK Metrics Suite is composed of 6 metrics, which are described in details in this document:

Details

Avoid unreferenced Functions (metric id 7860) This unified rule reports unreferenced artifacts on more than 50 objects types.including database (all supported RDBMS) functions and procedures.
To enable this rule for the T-SQL technology we need to add the techno-filter in the assessment model in CAST-MS

Details

Definition

The Number of Decision Points is the sum of all artifact’s Cyclomatic Complexity of the selected context. This “Total Cyclomatic Complexity” provides a useful and complementary evaluation of the application functional size based on the number of decision/control flow statements in the application’s code. An interpretation of this number is the number of test cases one should set up to test all paths through the application. A steep increase of this number would highlight a need for substantively more testing effort.
