De-Risking Rollouts with Contract Tests and Sandbox Data
Learn how to implement contract tests and sandbox data to ensure safer rollouts in your hiring tech stack.

## The $50K Hallucination Imagine this: your AI model just hallucinated in production, leading to a $50K payout in customer refunds. This scenario isn't just a nightmare; it can happen if your verification services aren't properly tested before deployment. In the world of engineering, especially when integrating with a
ATS or HRIS, the stakes are incredibly high. A single failure can not only drain your budget but also damage your brand's reputation and trustworthiness. To mitigate these risks, implementing contract tests and sandbox environments is not just advisable—it's essential.
## Why This Matters For engineering leaders, the integrity of your hiring process is paramount. Each integration point—whether it's your ATS or a third-party verification service—represents a potential failure point. Without rigorous testing, you risk exposing your organization to compliance issues and operational down
time. Contract tests and sandbox data help ensure that changes in your system won't disrupt existing functionality or lead to unexpected costs. By validating your integrations early, you can catch issues before they escalate, saving time and resources.
## How to Implement It 1. **Set Up Contract Tests**: Start by defining the expected behavior of your API endpoints. Use tools like Pact or Postman to create tests that simulate various scenarios. This helps verify that your integrations behave as expected. 2. **Create Sandbox Environments**: Develop a sandbox that mim
ics your production environment but uses dummy data. Use this space to test new features or integrations without affecting real candidates or operations. 3. **Define Rollback Procedures**: Before deploying any changes, establish clear rollback procedures. This ensures that if something goes wrong, you can quickly and,
safely revert to the previous version. 4. **Implement Canary Rollouts**: Instead of deploying changes to all users at once, consider rolling them out to a small subset first. Monitor performance and user feedback before a full deployment.
Key takeaways
- Implement contract tests to validate integrations early.
- Use sandbox data to simulate real-world scenarios.
- Establish rollback and kill switch mechanisms for safe deployments.
Implementation checklist
- Set up contract tests for API endpoints.
- Create sandbox environments with realistic data.
- Define clear rollback procedures before deployment.
- Implement canary rollouts to monitor changes.
Questions we hear from teams
- What are contract tests and why are they important?
- Contract tests validate the interactions between services, ensuring that the APIs behave as expected, which prevents integration failures.
- How can I create a sandbox environment?
- A sandbox environment mimics your production setup but uses dummy data, allowing you to test changes without affecting real operations.
- What is a canary rollout?
- A canary rollout is a deployment strategy where changes are released to a small user group to monitor performance before a full rollout.
