Java Code Metric Extractor

MetricExtractor

Java Code base.Metric Extractor

MetricExtractor aims to extract features from source code. More precisely, it gives information about a given method in a project. The ultimate goal is to use those features as metrics to associate a method (unit test) with a level of flakiness likelihood.

Supported features

• Assertion count
• Method size
• Depth of Inheritance
• Cyclomatic Complexity
• Explicit wait count
• Presence of hard coded timeout
• Body

Dependencies

• Spoon v7.5.0
• JDK 12
• Simple-json 1.1.1

Install

• Clone the project. git clone [e-mail]:GuillaumeHaben/MetricExtractor.git && cd ./MetricExtractor
• Install dependencies Reimport All Maven Projects

Run with Intellij

• In ./src/main/java/base/Main.java right-click on the main function, Create 'Main.main()'...
• Add Program arguments: -interactive
• Build

Run from the Command Line

• Get the classpath by running mvn dependency:build-classpath -Dmdep.outputFile=tmpCp.txt
• In ./metricExtractor.sh replace classpath with the one in tmpCp.txt (Keep ./target/classes/:)

Usage

• Set projectPath in src/main/java/base.Main.java to the Java project you wish to analyze.
• Run base.Main.java (IntelliJ)
• Run ./metricExtractor.sh (Command Line)

Options

-interactive to run an interactive command. (only option in this case) -projectPath followed by the absolute path to the Maven project you want to analyze. -getAllTestMethods will get metrics for all tests in the project -getAllMethods will get metrics for all methods (CUT) in the project -listPath followed by the aboluste path to a .txt file containing list of CLASS_NAME.METHOD_NAME. Will get metrics for them.

Results are saved in ./results/PROJECT/

Work in Progress

• Test your code
• Refactor code
• Add base.Search by list of methods
• Add Depth of Inheritance metric
