WP4 Interoperability Test Bed

This repository hosts the interoperability test bed for WP4. It provides test frameworks, conformance checks, and use case scenarios to validate interoperability across wallets, protocols, and domain-specific functions.

✅ Conformance Overview

Here is an overview of all implementers in WE BUILD that provided a conformance report for 1 or more of our test cases showing they passed them.

🚀 Getting Started

Follow these steps to set up and run the WP4 Interoperability Test Bed. See the documentation for more detailed information.

We did a presentation and demo on the ITB in January 2026. Slides and video are available on OpenSocial.

Start Testing - Onboarding

Step 1 Contact #itb-support Slack channel with:

• Organisation name and contacts (technical + governance)
• Intended roles: Issuer / Verifier / Holder (one or more)
• Targeted profiles & protocol versions (e.g. OID4VCI 1.0, OID4VP 1.0, SD-JWT, mdoc) We will contact you via e-mail to get the information listed in step 2.

Step 2 Provide base URLs (dev/acc/prod) and security mode (bearer, mTLS, x-apikey). You will now receive the following:

• An ITB tenant with namespaced configuration
• Credentials (per tenant/profile)
• Access to reference test suites and the reporting portal

Before you can test, you need to implement and deploy an operational service (wallet/holder, issuer, verifier) based on the WE BUILD Conformance Specifications

Start Testing - Integrated Wallets

1. Clone the repository

git clone git@github.com:webuild-consortium/wp4-interop-test-bed.git
cd wp4-interop-test-bed

2. Install dependencies

If a given test suite requires dependencies, see its README inside:

• tests/...
• wallet-conformance-src/

3. Run tests

# Example: run base protocol tests
cd tests/base-protocols
# insert your command here (e.g., pytest, npm test, etc.)
