How to Achieve 99.99% Uptime with Reliable Microservices Testing

1. Unit Testing

Unit testing checks whether individual microservices work as intended. It helps catch bugs early and ensures that core functions are stable.

Example: Testing a login microservice to ensure it validates user credentials correctly.

2. API Testing

Microservices rely on APIs to communicate. If an API call fails, it can break the whole system. API testing ensures that data flows correctly between services.

Example: Testing an order processing microservice to confirm that payment data is processed correctly.

👉 Vervali’s API testing services help identify communication failures before they reach production.

3. Integration Testing

Even if individual microservices work, they need to communicate properly as a whole system. Integration testing checks how services interact with each other.

Example: Testing how a product selection service interacts with the checkout service.

4. Performance Testing

Can your app handle 100,000 users at once? Performance testing services checks how well your microservices handle high traffic and stress conditions.

Example: Testing whether the system remains stable when 5,000 users try to check out at the same time.

5. Automation Testing

Manual testing can’t keep up with fast release cycles. Automation testing ensures that every update is tested before deployment — without slowing down development.

Example: Running an automated end-to-end test to validate an entire user journey.
