API Testing
Comprehensive, AI-enhanced API testing solutions simplify complex test case automation, elevating testing processes and empowering teams to ensure flawless API functionality, performance, and reliability.
Use natural language with agentic AI to slash hours from API test creation and environment setup—so your team can test earlier, faster, and with fewer roadblocks.
With support for 120+ message formats and protocols, testers can easily validate a wide range of use cases and technology stacks.
Repurpose existing functional test cases to validate nonfunctional requirements early in the SDLC with shift-left API security and performance testing.
Test impact analysis pinpoints which API tests to run when your applications changes, so you run less, get faster feedback, and keep your CI/CD pipeline moving.
With the SOAtest AI Assistant, you can turn service definitions and natural language instructions into complete, parameterized test scenarios with meaningful assertions and test data—just by having a conversation. Whether you’re new to testing or a seasoned pro, you’ll move faster and test smarter.
Use natural language to define validations and pull data from responses—even when outputs are unpredictable. It’s a faster, easier way for you to handle complex scenarios and keep your tests maintainable.
You also get support for testing of AI systems that use Model Context Protocol (MCP) servers, enabling codeless validation of the tools AI agents rely on—all within the SOAtest UI.
With Parasoft SOAtest’s Smart API Test Generator, you can record REST calls during UI testing or by proxying traffic between services. Then let AI do the heavy lifting by analyzing flows, extracting parameters, and generating codeless, ready-to-run multi-step API tests with dynamic data flow.

Visual, codeless tools let you easily create, extend, and organize tests across APIs, web UIs, databases, ESBs, even MCP servers common in AI-infused systems. No deep technical skills are required. Supporting over 120 protocols and message formats, SOAtest gives you a unified framework to validate business logic end-to-end.
Using SOAtest, you can:
60%
Reduction in test creation time.
80%
Increase in API test coverage.
Enable true continuous testing workflows by leveraging API testing in concert with service virtualization and environment management to create resilient, effective, and efficient automated test cases while eliminating environmental obstacles that hinder test velocity and cause testing downtime.
Continuous testing is a process that empowers teams to build quality into software development and accelerate the delivery of high-quality customer experiences. SOAtest easily integrates into all popular CI/CD pipelines for execution, quality gates, and reporting.
Teams can optimize testing pull requests by using SOAtest’s test impact analysis to identify and run the subset of test cases required to validate the application changes. Continuously publish test results into Parasoft DTP for advanced reporting, code coverage analysis, API coverage analysis, and requirements traceability.
Leverage Virtualize, SOAtest’s sister solution, to stabilize the environment for automated testing by simulating unstable or unavailable integration and environment components. Testing teams can use Virtualize to create completely virtual test environments that can be deployed or destroyed on demand.

API testing for microservices ensures seamless communication between independent service components, guaranteeing reliability and scalability in distributed architectures. By rigorously performing end-to-end testing in microservices architectures, teams maintain robustness and agility, making sure microservices deliver consistent performance across diverse environments.
Microservice testing presents a complex challenge for two primary reasons.
Supporting 120+ protocols and message formats, SOAtest provides teams with rich support and flexibility to craft test scenarios for complex distributed systems.
It can be difficult to measure how thoroughly microservices have been tested due to their distributed nature. Our code coverage solution helps teams understand the sufficiency of their testing practice by capturing code coverage of Java and .NET microservices as they’re exercised by end-to-end test scenarios. Code coverage is reported for each individual microservice or aggregated for the application as a whole.
Validating modified microservices in the context of the entire application can be challenging and time-consuming. Parasoft’s test impact analysis identifies and executes the specific subset of end-to-end tests that must be run to validate changes in an individual microservice.

Shift nonfunctional testing left as part of the SDLC process by reusing existing API test cases for API security and performance testing.
Use SOAtest with embedded OWASP ZAP or integrate with PortSwigger’s Burp Suite to repurpose API tests for penetration testing with ease. Teams can run security analysis for individual REST APIs or full API scenarios by selecting specific test cases and configuring them to check for vulnerabilities related to OWASP Top 10 or CWE.
Parasoft’s built-in documentation simplifies steps for testers to remediate errors reported in SOAtest. Managers and security auditors can produce detailed HTML reports that correlate violations to specific OWASP or CWE rule IDs for easy tracking.
Teams can repurpose SOAtest API test cases for performance testing in a similar way.

SOAtest’s AI-powered test impact analysis helps teams gauge what lines of code each test case executes. It automatically identifies impacted test cases when you modify code. Testers only need to execute the subset of test cases required to validate the changes instead of the entire regression test suite. They can quickly validate application changes and get fast feedback on whether the changes impacted functionality.
When API contracts change, updating the existing test cases to reflect the new schemas can be time-consuming. SOAtest’s Change Advisor helps identify test cases impacted by API changes and swiftly updates them. Change Advisor analyzes the outdated service definition file against the latest version and creates a change template that testers can apply to their entire suite of tests to automatically bulk-refactor the test cases to support the new API schemas.
