NullDetect

Static analyzer for detecting redundant null-comparisons in Java class-files. For this NullDetect parses compiled class-file and aplies data-flow analysis.

Prerequisites

• JDK 1.8
• Maven:
  • ASM 5.2 to parse class-files and as a base for data-flow analysis
  • JUnit 4.12 for unit testing
  • TestFX 4.0.8 (Core and JUnit) for GUI testing

Build

mvn package

Usage

Run GUI with:

java -jar <jar-with-dependencies>

To analyze select directory with class-files and press Start button. You can cancel background analysis by pressing Cancel button or selecting new directory with help of Brwose button.

ToDo:

• GUI testing
• Improve documentation
• Migrate to ASM 6.0
• Migrate to JUnit 5 and use dynamic tests for individual test resources
• Separate CSS from GUI
• Improve analysis
• Simplify AnalyzerTask (AnalyzerTask could simply run AnalyzerJobs. Individual AnalyzerJobs could write their results directly into observable concurrent map)
• Add automatic compilation of test resources
