Software Measurement Project - SOEN 6611-2184-D (Winter 2019)

---

The aim of this project is to calculate several software metrices and to define correlation between them.

We calculated following metrices.

1. Statement Coverage: Statement coverage is a white box testing technique, which involves the execution of all the statements at least once in the source code. It is a metric, which is used to calculate and measure the number of statements in the source code which have been executed.
2. Branch Coverage: ranch coverage is a testing method, which aims to ensure that each one of the possible branch from each decision point is executed at least once and thereby ensuring that all reachable code is executed.
3. Mutation Score: Mutation testing is used to design new software tests and evaluate the quality of existing software tests.
4. Cyclomatic Complexity: Cyclomatic complexity is a software metric used to indicate the complexity of a program. It is a quantitative measure of the number of linearly independent paths through a program's source code.
5. Relative Code Churn Code churn is a measure of the amount of code change taking place within a software unit over time.
6. Software Defect Density

Used tools for different metrices :

CLOC - Counting lines of the program

Added Dependency Plugin in pom.xml for PIT Test as below

How did we run Jacoco for our project

How did we run for PIT Tool for our project

Added Dependency Plugin in pom.xml for PIT Test as below

We didn't configure it for only certains classes, instead we ran it on entire project.On an average, It took 1-2 hours for 4 projects(collections, configurations, io, lang) and 8.5 hours for math.

Find the screenshot below.

Following command to compile and run unit tests

mvn clean install

Following command to run PIT Test

mvn org.pitest:pitest-maven:mutationCoverage -X

X is for debug mode so we can see what's going on.
