Overview of Analyzed Files

Basic stats on analyzed files

Intro

For analysis purposes we separate files in scope into several categories: main, test, generated, deployment and build, and other.

The main category contains all manually created source code files that are being used in the production.
Files in the main category are used as input for other analyses: logical decomposition, concerns, duplication, file size, unit size, and conditional complexity.
Test source code files are used only for testing of the product. These files are normally not deployed to production.
Build and deployment source code files are used to configure or support build and deployment process.
Generated source code files are automatically generated files that have not been manually changed after generation.
While a source code folder may contain a number of files, we are primarily interested in the source code files that are being written and maintained by developers.
Files containing binaries, documentation, or third-party libraries, for instance, are excluded from analysis. The exception are third-party libraries that have been changed by developers.

Main Code

All manually created or maintained source code that defines logic of the product that is run in a production environment.

The following criteria are used to filter files:

files with paths like ".*".

37 files match defined criteria (2,253 LOC, 100.0% vs. main code):

2 *.css files (953 LOC)
30 *.xml files (750 LOC)
3 *.js files (417 LOC)
1 *.java files (126 LOC)
1 *.yaml files (7 LOC)

" *.css" is biggest, containing 42.3% of LOC.
" *.yaml" is smallest, containing 0.31% of LOC.

Generated Code

Automatically generated files, not manually changed after generation.

The following criteria are used to filter files:

files with any line of content like "\<\!\-\-[ ]*Generated by .*".

31 files match defined criteria (7,913 LOC, 351.2% vs. main code). All matches are in *.html files.

Build and Deployment Code

Source code used to configure or support build and deployment process.

files with paths like ".*[.]gradle".
files with paths like ".*/AndroidManifest[.]xml".
files with paths like ".*[.]git[a-z]+".
files with paths like ".*/[.]gitignore".
files with paths like ".*[.]bat".

11 files match defined criteria (326 LOC, 14.5% vs. main code):

6 *.gradle files (182 LOC)
4 *.xml files (83 LOC)
1 *.bat files (61 LOC)

" *.gradle" is biggest, containing 55.83% of LOC.
" *.bat" is smallest, containing 18.71% of LOC.
