JsonUnit diff attachment integration for Allure Java.

Use this module when your tests compare JSON payloads with JsonUnit and you want readable JSON differences attached to Allure Report.

• Allure Java 3.x requires Java 17 or newer.
• This module targets JsonUnit 5.x.
• The current build validates against JsonUnit 5.1.2.

Gradle:

dependencies {
    testImplementation(platform("io.qameta.allure:allure-bom:<allure-version>"))
    testImplementation("io.qameta.allure:allure-jsonunit")
}

Maven, with allure-bom imported in dependency management:

<dependency>
    <groupId>io.qameta.allure</groupId>
    <artifactId>allure-jsonunit</artifactId>
    <scope>test</scope>
</dependency>

Use JsonPatchMatcher.jsonEquals(...) when comparing JSON payloads.

assertThat(actualJson, JsonPatchMatcher.jsonEquals(expectedJson));

• JsonUnit comparison differences.
• A rendered JSON diff attachment named JSON difference.
• Failed assertions keep their normal assertion failure status and include the diff as supporting evidence.
