How to Run Tests in the IPED Project

Execute mvn clean test from the repository root to run all JUnit 4 unit tests across every Maven module, or use the -Dtest parameter to target specific classes and methods.

According to the sepinf-inc/IPED source code, this digital forensics platform is built with Maven and Java 11, organizing its validation suite as standard JUnit 4 tests within src/test/java directories. Whether you are verifying parser logic or contributing new features, knowing how to run tests in the IPED project ensures your code integrates correctly with the existing architecture. The parent pom.xml automatically configures the Maven Surefire plugin, requiring no additional test runners or manual environment setup.

Running the Complete Test Suite

The most reliable way to validate your changes is to execute the entire test suite from the repository root. This approach compiles all Java 11 sources and runs every unit test defined across the multi-module project.

Run all tests using the standard Maven lifecycle:

mvn clean test

To build the final release artifacts while running tests, use the install phase:

mvn clean install

Both commands trigger the Surefire plugin defined in the parent pom.xml, which automatically discovers and executes JUnit 4 tests located in src/test/java folders. The JUnit 4 dependency is declared with test scope in the central build descriptor, ensuring Maven downloads the required libraries without polluting runtime dependencies.

Running Specific Test Classes or Methods

When debugging a specific component, targeting individual tests reduces feedback time. The IPED project supports Maven’s standard test selection syntax via the -Dtest parameter.

Run a single test class by specifying its simple name:

mvn -Dtest=WinXTimelineParserTest test

Run a specific test method using the hash delimiter:

mvn -Dtest=WinXTimelineParserTest#testParseTimeline test

This approach is particularly useful when iterating on parser logic in modules like iped-parsers-impl, where tests such as WinXTimelineParserTest.java validate specific file format handling. The -Dtest flag accepts wildcards and comma-separated lists for broader selection patterns.

Skipping Tests During Development Builds

For rapid compilation checks or when you need to build artifacts without waiting for the full test suite, Maven allows test suppression.

Add the -DskipTests flag to any build command:

mvn clean install -DskipTests

Use this option sparingly; the IPED test suite includes regression tests for digital forensics parsers that catch format-specific edge cases. Skipping validation may allow subtle bugs to reach production builds.

Test Structure and Organization

Understanding the physical layout of the test suite helps locate relevant examples and resources. The IPED project follows standard Maven directory conventions with clear separation between source and test code.

Key locations include:

• pom.xml — The parent Maven descriptor at the repository root declares JUnit 4 dependencies and Surefire plugin configuration, centralizing build definitions for all modules.
• iped-parsers/iped-parsers-impl/src/test/java/iped/parsers/winx/WinXTimelineParserTest.java — Exemplifies the typical JUnit 4 test structure used throughout the project, demonstrating how parser classes are instantiated and validated against expected outputs.
• iped-parsers/iped-parsers-impl/src/test/resources — Contains sample files (evidence images, chat databases, registry hives) used as input data for parser tests, allowing integration-style validation without external dependencies.

Test classes reside in packages mirroring their corresponding source code locations, making it intuitive to find WinXTimelineParserTest adjacent to the WinXTimelineParser implementation it validates.

Summary

• Full suite execution: Run mvn clean test from the repository root to compile Java 11 sources and execute all JUnit 4 tests via the Surefire plugin.
• Targeted testing: Use -Dtest=ClassName for single classes or -Dtest=ClassName#methodName for individual methods to speed up debugging cycles.
• Build integration: The mvn clean install command compiles, tests, and packages the application without requiring additional configuration.
• Test locations: Unit tests live in src/test/java within each Maven module, with resources in src/test/resources providing sample forensic data for validation.

Frequently Asked Questions

How do I run only the WhatsApp parser tests?

Use the -Dtest parameter with the specific class name: mvn -Dtest=WhatsAppParserTest test. This executes only the test methods defined in WhatsAppParserTest.java without running the broader suite, significantly reducing execution time when iterating on chat parsing logic.

Can I run tests if I only have Java 8 installed?

No. The IPED project requires Java 11 for compilation and test execution. Attempting to run mvn test with Java 8 will result in compilation errors due to language level requirements specified in the parent pom.xml.

Where are the test data files stored?

Sample forensic files and test inputs are stored in src/test/resources directories within each module. For example, the iped-parsers-impl module maintains parser-specific test data at iped-parsers/iped-parsers-impl/src/test/resources, allowing tests like WinXTimelineParserTest to load evidence samples from the classpath during execution.

Is it possible to run tests in a specific Maven module only?

Yes. Navigate to the specific module directory (e.g., cd iped-parsers/iped-parsers-impl) and run mvn test from that location. Maven executes only the tests within that module and its dependencies, which is useful when working on isolated components without triggering the entire multi-module build.
