Description / Features

Total Quality plugin combines four domains measures (architecture, design, code, and tests) in order to calculate a global and unified project quality health. Plugin provides metrics at project level only.

The default formula is :

TQ= 0.25*ARCH + 0.25*DES + 0.25*CODE + 0.25*TS

where :

Architecture (ARCH)

ARCH = 100 - TI

TI = Tangle Index

Design (DES)

DES = 0.15*NOM + 0.15*LCOM + 0.25*RFC 0.25*CBO + 0.20*DIT

NOM = (1 - (class_complexity - 12) / (acel * 12)) * 50 + (1 - (method_complexity - 2.5) / (acel * 2.5)) * 50

LCOM = (1 - (lack_of_cohesion_of_method - 1) / (acel * 1)) * 100

RFC = (1 - (response_for_class - 50) / (acel * 50)) * 100

CBO = (1 - (efferent_coupling - 5) / (acel * 5)) * 100

DIT = (1 - (depth_of_inheritance_tree - 5) / (acel * 5)) * 100

Code (CODE)

Code = 0.15*DOC + 0.45*RULES + 0.40*DRYNESS

DOC = Documented API density

RULES = Rules compliance index

DRYNESS = 100 - Duplicated lines density

Test (TS)

Testing quality is based on coverage metric family (coverage, and test success).

Test = 0.80*COV + 0.20*SUC

COV = Code coverage

SUC = Unit Tests success density

Configuration

Every limit and every formula should be configure with administration view.
If you want to remove a metric just do,

"ARCH=0.25 DESIGN=0.25 CODE=0.50 TESTS=0.00"

Known limitations and TODO

See SONARPLUGINS-415

Usage & Installation

1. Copy the jar into /extensions/plugins/ directory
2. Restart Sonar Web server
3. Launch a new quality analysis and the metrics will be fed
