On June 27, 2024, we are excited to announce the launch of JSONassertify. JSONassertify is a modernization fork of the widely used JSONassert library, designed to provide developers with a secure, actively maintained alternative for JSON unit testing that remains compatible with Java 8.

Why JSONassertify Matters

Many Java projects rely on JSONassert to simplify the testing of REST interfaces by comparing JSON structures logically rather than as literal strings. This prevents tests from becoming brittle when insignificant changes, such as element order, occur in the output.

However, as the original library evolved, some updates introduced requirements for significantly newer Java versions, leaving developers on Java 8 without a maintained path forward. JSONassertify fills this critical gap. By targeting Java 8, it ensures that a vast ecosystem of applications can continue to use powerful JSON assertion tools without being forced into a premature or risky runtime upgrade. Beyond compatibility, JSONassertify prioritizes security by updating dependencies to address known vulnerabilities, providing peace of mind for production environments.

Key Features of JSONassertify

JSONassertify provides the robust logical comparison capabilities that developers love about the original library, while introducing modern engineering standards:

  • Logical JSON Comparison: Compare JSON structures based on content rather than string equality, allowing for flexible tests that ignore order or extra data in non-strict mode.
  • Java 8 Compatibility: Full support for Java 8, ensuring accessibility for a wide range of enterprise environments.
  • Modernized Tooling: The project is built with JUnit 5 for internal testing and integrated with GitHub Actions for a reliable, automated CI/CD pipeline.
  • Secure Foundations: Integrated Dependabot ensures that dependencies are kept up-to-date and security patches are applied promptly.

Getting Started

Since JSONassertify is a fork of JSONassert 1.5.1, it is designed to be a near drop-in replacement. To integrate JSONassertify into your project, follow these steps:

  1. Update Your Dependency: Add the following to your pom.xml: 
    <dependency>
    <groupId>com.unitvectory</groupId>
    <artifactId>jsonassertify</artifactId>
    <version>0.0.1</version>
    <scope>test</scope>
</dependency>
  2. Update Imports: Replace all occurrences of org.skyscreamer.jsonassert.* with com.unitvectory.jsonassertify.*.
  3. Review JSON Data: Because JSONassertify uses the standard org.json library, please check your test data for duplicate keys. Unlike some previous implementations, org.json may throw an error when encountering duplicate keys, which encourages cleaner and more predictable data structures.

We invite you to adopt JSONassertify to make your JSON testing more resilient and your codebase more secure.
