API Contract Testing

OpenAPI-driven API and microservices quality

Generate provider and consumer-driven contract tests from OpenAPI specs. Check both the API and spec file. Get insights into quality patterns across large API and microservices programs.

Scalable API Testing and Insights: Application -> Microservice -> Database

Increase release confidence—Manage microservices test case complexity.

Make OpenAPI-driven contract testing an initial step in your API quality engineering workflow. Reduce integration testing bottlenecks. Manage risk at every stage of the development lifecycle by extending contract tests into API functional and load tests or monitors that can run in any environment.

Deploy microservices with confidence

  • Adding even a single microservice on top of existing microservices can create hundreds of new ways that APIs can interact.Test maintenance can quickly get out of hand. That’s why we’ll give you peace of mind by making it easy to update contract tests whenever spec files are changed. Plan microservices sprints with insights: Only Sauce Labs unifies contract, functional, integration, and load API testing on a secure collaboration platform. Ensure testing reports, dashboards and feedback loops are highly usable by anyone across the whole development lifecycle. Diagnose and debug quickly. View historic quality trends.

OpenAPI Mocking & Testing

Generate mocks from OpenAPI specs. Reduce risk early in API development.

Ready to scale integrations and microservices? Instantly generate API mocks for consumer-driven contract testing from a single source of API truth: your OpenAPI specifications.

Get fast feedback that you can trust

  • OpenAPI-driven mock servers and contract tests capture all the ways that an endpoint can behave. Traditional contract (“pact”) testing relies on recorded API conversations, often missing many types of endpoint behavior.

Reduce breaking changes that lead to rollbacks

  • Today, contract testing must also validate whether OpenAPI specs match the schema. Specs may be handled by multiple teams and contractors who may make changes without enough domain knowledge. With insights from Sauce Labs, you’ll know exactly what needs to be fixed.

What is Contract Testing?

This blog post discusses the key differences between contract testing and API functional testing and includes a useful checklist of contract testing best practices.

One Platform: API Testing, Monitoring and Insights

Security and compliance

Security and compliance

After more than 5 billion tests, enterprise customers have long trusted Sauce Labs to take testing security and compliance very seriously. Sauce Labs offers certification across ISO 27701, 27001 and SOC 2 Type 2.

Scalable test automation

Scalable test automation

The world runs on integrations and microservices. But runaway test complexity makes it hard to achieve quality at speed. Only Sauce Labs helps you tackle the complexity by testing smarter, not harder via unified insights and predictive capabilities.

No seat-based pricing

No seat-based pricing

API-first and microservices development require shifts in how we work. Only Sauce Labs frees managers to make agile changes among distributed teams and contractors without worrying about disruptions due to slow onboarding and seat licenses.
