APIs are critical business assets They service users inside and

outside the organization They offer competitive differentiation Quality is non-negotiable

APIs and the Modern Enterprise

@SmartBear | #APIDataDrive

Not enough time Minimal communication Hard-coded, narrow

test data Only positive outcomes

are evaluated Results aren’t tracked

API Testing Isn’t Keeping Up

@SmartBear | #APIDataDrive

Business users aren’t engaged Valuable time is wasted Application logic isn’t exercised Latency isn’t accurately measured

Risks of Not Testing with Data

@SmartBear | #APIDataDrive

There’s no longer a good reason not to use data

Modern tools and techniques make data-driven testing easier than ever

This is a critical ingredient for higher quality APIs

Transforming Testing with Data

@SmartBear | #APIDataDrive

The foundation for automated testing

Smooth tie-in with agile methodologies

Better business logic measurement

More realistic performance results

Benefits of Data-Driven Testing

@SmartBear | #APIDataDrive

Use lots of realistic information Test both positive and negative outcomes Employ dynamic assertions Repurpose functional tests for performance Drive virtual APIs with meaningful data

Optimal Data-Driven Testing

Typical Manual interaction with service/API

Basic Use in-line, generated data

Intermediate Apply site-specific knowledge to data

Advanced Conduct intelligent, round-trip testing

Four Scenarios

@SmartBear | #APIDataDrive

Static data is dangerous when measuring performance

Databases, app servers, and Web servers all cache responses

The only way to get realistic metricsis to request varied outcomes

Performance Testing & Data

@SmartBear | #APIDataDrive

APIs aren’t always available for testing

Testing often requires minimum viable response data just to get started

API virtualization gives you control over simulations (logic + data)

Virtualization & Data

@SmartBear | #APIDataDrive

Key Takeaways

17

Create APIs with Confidence

Strategic APIs require extensive testing

Automation is essential

Data-driven testing is a foundation for

automation

Automation liberates testers from rote tasks
