Validating Plugin Version Extraction Functionality in JADX

This test suite validates the version extraction functionality in the JADX plugin utilities. It ensures proper parsing of version numbers from plugin filenames through targeted unit tests using JUnit and AssertJ assertions.

Test Coverage Overview

The test coverage focuses on the extractVersion utility method, validating different version number formats in plugin filenames.

Key functionality tested:

Standard three-segment version (v1.2.3)
Two-segment version format (v1.2)
Version without ‘v’ prefix

Edge cases include varying filename patterns and version number lengths.

Implementation Analysis

The testing approach employs JUnit Jupiter with AssertJ assertions for robust version string validation. The implementation uses a single test method with multiple assertions to verify different version extraction scenarios.

Testing patterns include:

Fluent assertion syntax with AssertJ
Multiple test cases in single method
Static import optimization

Technical Details

Testing tools and configuration:

JUnit Jupiter test framework
AssertJ assertion library
Static imports for clean test syntax
Java package structure: jadx.plugins.tools.utils

Best Practices Demonstrated

The test suite demonstrates clean testing practices with focused assertions and clear test cases. Notable practices include:

Descriptive test method naming
Efficient test case organization
Clear assertion statements
Consistent version string validation
