Testing contract

Expected to pass

Scenario: Exercise JAR - Resource Archive in its zip workflow. A Java Archive (JAR): a ZIP with a META-INF/MANIFEST.MF and resource files only (no .class bytecode).
Expected result: ZIP package contains 4 members; first members: META-INF/MANIFEST.MF, messages.properties, config/app.json, README.txt. Declared feature checks: members=4; manifest=META-INF/MANIFEST.MF; contains=properties, JSON, text, no compiled code.

What is a .jar file?

JAR (Java Archive) is a ZIP-based package that bundles Java class files, resources, and a manifest into a single distributable unit. The manifest can declare an entry point and metadata, making the JAR executable or usable as a library. It is the standard packaging format for the Java ecosystem.

How to use this file

Use an example JAR to test ZIP-based extraction, manifest parsing, classpath and dependency tooling, and Java build or deployment pipelines.

How to use this file for testing

“JAR - Resource Archive” is a deterministic Testaroo fixture for Conversion testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.

Documented properties for this file: JAR (ZIP family). Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.

Archive fixtures are documented down to their member list (shown on this page) and are deliberately safe, no zip bombs, executables, or hidden payloads. Test extractors against nested, unicode, empty, and encrypted variants.

Code examples

unzip -l resources.jar     # list members
unzip resources.jar -d out/  # extract
