  • Industry leader since 2002
  • Recognized for "ease for use", intuitive interface
  • Includes advanced automation for message layer and Web UI
  • Extensive protocol and technology support
  • End-to-end testing across multiple endpoints (services, ESBs, databases, mainframes, web UI, ERPs...)
  • Advanced automated test generation
  • Designed to support continuous testing

API Testing

Parasoft API Testing provides unprecedented test automation to help testers ensure the security, reliability, and performance of transactions across modern business systems. From a single intuitive interface, it automates "end-to-end" test scenarios across multiple endpoints (APIs/services, databases, Web UIs, ESBs, mainframes…). Beyond robust support for REST and web services, the solution supports an industry-leading 120+ protocols/message types.
  • Integrate functional/load/security testing with test data management, service virtualization, and defect prevention
  • Generate extensible, reusable, easily maintainable tests with 100% coverage
  • Automate continuous regression testing with sophisticated validations
  • Construct advanced end-to-end test scenarios combining tests for the web layer, API layer, mobile application, etc. into a single integrated scenario

SOA Testing

  • Designed from the ground up to simplify the testing of GUI-less services
  • Generate extensible, reusable, easily maintainable tests with 100% coverage
  • Design sophisticated tests without scripting or coding
  • SOA-Aware: broad native support for platforms, technologies, protocols
  • Event tracing and validation (ESBs, brokers, databases, more)

API Security Testing

  • Run penetration testing at the API / message layer and web UI level
  • Uncover OWASP vulnerabilities
  • Validate authentication, encryption, and access control
  • Find and fix security vulnerabilities earlier
  • Pinpoint where attacks really succeed—not just areas that are susceptible

Load and Performance Testing

  • Validate functionality and performance under various loads
  • Simulate extreme loads and/or test from different locations
  • Expose concurrency issues in multithreaded applications
  • Define and enforce expected Quality of Service (QoS) metrics for SLAs
  • Test using existing Parasoft tests, JUnit tests, or lightweight socket-based components

Web UI Testing

  • Define easily-maintainable, low-noise tests without scripting
  • Automate regression testing without annoying false positives
  • Facilitate collaboration between non-technical and technical team members
  • Enforce consistency across the web UI
  • Run cross-browser testing (including mobile browser interfaces)


Runtime Error Detection

  • Expose critical defects as the application is exercised
  • Works from unit testing through application/system testing
  • Reports only defects that actually occur
  • Lightweight and suitable for embedded testing
  • Integrated with static analysis, unit testing, code review & more

Service Virtualization

Parasoft Service Virtualization helps development and QA teams access the complete, realistic test environments needed to develop or test an application—anytime, anywhere. Testing is often delayed or cut short because it's difficult to access the complete, realistic test environments required to test meaningful transactions. By replacing unavailable dependencies with easily accessible and configurable "virtual assets", service virtualization allows teams to start testing earlier, test more completely, and test continuously.
  • Capture and simulate live system behavior from recording
  • Rapidly model incomplete/unavailable components from service definitions and logs
  • Easily configure complex test conditions (e.g., “what-if,” security, concurrency, fail-over, performance, and negative test scenarios)
  • Simulate any system interactions—supports REST & web services, plus an industry-leading 120+ protocols/message types
  • Get the exact test environment you need, on-demand

Test Environment Management

Parasoft Continuous Testing Platform (CTP) integrates and extends the above API testing and service virtualization capabilities via an intuitive web-based interface for creating, managing, sharing, and executing test environments (including service virtual assets) and tests. Environment Manager (a component of CTP) unites test environment management (test environment setup, visualization, validation, and provisioning), service virtualization (virtual asset creation, configuration, and deployment), and API testing (test creation, management, and execution).
  • Visualize the dependencies associated with an AUT and specific test environments
  • Easily configure all test environment components—including virtual asset performance, test data, and response logic
  • Instantly provision "disposable" test environments with zero impact to the organization
  • Identify test environment issues before they compromise the accuracy of your test results
  • Assess the impact of a change to any specific component

Development Testing

  • Prevent and expose code-level defects that impact application security, reliability, and performance
  • Integrate static analysis, unit testing, coverage, code review, more
  • Expose defects when they are easier, faster, and cheaper to fix
  • Ensure consistency across large and distributed teams
  • Increase productivity and agility while improving quality
