gRPC client interceptor integration for Allure Java.

Use this module when your tests call gRPC services and you want method calls, metadata, messages, timing, and statuses to appear in Allure Report.

• Allure Java 3.x requires Java 17 or newer.
• This module targets gRPC Java.
• The current build validates against gRPC Java 1.83.1 and Protobuf Java 4.35.1.

Gradle:

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

Maven, with allure-bom imported in dependency management:

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

Attach io.qameta.allure.grpc.AllureGrpc to a gRPC channel or stub as a client interceptor.

ManagedChannel channel = ManagedChannelBuilder.forAddress("localhost", 8080)
        .intercept(new AllureGrpc())
        .usePlaintext()
        .build();

Request and response metadata are captured by default. Cookie metadata is represented as structured HTTP exchange cookies, so header and cookie redaction can be configured through the HTTP exchange capture policy.

Use the builder to add application-specific header and cookie redaction:

ClientInterceptor allure = AllureGrpc.builder()
        .redactHeader("x-api-key")
        .redactCookie("session")
        .build();

Metadata capture can be disabled independently for either direction:

ClientInterceptor allure = AllureGrpc.builder()
        .captureRequestMetadata(false)
        .captureResponseMetadata(false)
        .build();

For other HTTP exchange capture options, configure the underlying exchange builder:

ClientInterceptor allure = AllureGrpc.builder()
        .configureExchange(exchange -> exchange.setMaxBodySize(256_000))
        .build();

• gRPC method calls as Allure steps.
• Request and response messages, metadata, status, and timing.
• Repeated metadata values in their original order; binary metadata values are Base64-encoded.
• Stream metadata for unary and streaming calls where available.
