Developers or QA who want an automated testing software solution

Parasoft has layered agentic AI capabilities onto C/C++test through a new MCP server, shifting test automation from tool-centric approaches to autonomous-driven assurance, where compliance, coverage, and quality are continuously enforced across the software lifecycle. AI-driven test generation, powered by MCP-enabled intelligent agents, accelerates test creation and coverage, reducing manual effort in writing unit tests. Parasoft also offers a GenAI agent that resides within Microsoft Copilot and integrates with VS Code to find and fix static analysis violations, plus an AI documentation agent aimed at increasing utilization of Parasoft's static and dynamic testing tools and optimizing ROI in software testing automation. Together, these position AI less as a bolt-on feature and more as an assistive layer across test generation, violation remediation, and compliance workflows.

Parasoft C/C++test is built around automating as much of the C/C++ testing lifecycle as possible, rather than relying on manual test-writing and execution. It combines static analysis, unit testing, and code coverage into a single integrated workflow, so tests can run automatically as part of everyday development instead of being a separate, manual phase. A few key ways it delivers automation: - Automated test generation - Real-time feedback during execution -CI/CD Integration - AI driven acceleration - Reviewable, source-code-based artifacts Together, this positions C/C++test as covering the "Automated Testing" category end-to-end: generating tests, executing them, catching failures/coverage gaps, and feeding results into CI/CD — with AI increasingly reducing the manual effort at each step.

Parasoft C/C++test measures structural code coverage during unit, integration, and functional testing, supporting metrics including statement, branch, MC/DC, call, and object/assembly coverage. Coverage can be captured on host, simulator, or target hardware, and integrates with open-source frameworks like GoogleTest, Boost.Test, and CppUnit for teams using those instead of C/C++test's built-in framework. Results feed into Parasoft DTP for centralized, per-test coverage reporting and trend tracking across builds, helping teams both identify gaps and satisfy the coverage requirements mandated by standards like ISO 26262 and DO-178C.

Parasoft C/C++test is designed to embed testing directly into CI/CD pipelines rather than treating it as a separate, end-of-cycle phase. Static analysis, unit testing, and code coverage integrate into build tools and continuous integration infrastructure, automating a broad range of coding best practices and automatically sending results to Parasoft DTP for aggregation and trend analysis across builds. One customer noted they've embedded test automation and static code analysis early in the development cycle, calling it a win for quality assurance in safety-critical automotive projects. This continuous approach extends to compliance as well: for regulated industries, C/C++test enforces coverage, coding-standard, and traceability requirements on every build rather than as a one-time gate, so compliance and quality are checked continuously rather than verified only before release.

Parasoft C/C++test supports functional testing through unit and system-level testing that verifies code behaves correctly against expected requirements, not just structure or style. It automatically generates extensible test cases that can be executed on the host, simulator, and in the actual target environments to verify code robustness and verify functional results, alongside gathering code coverage metrics. Generated tests can capture current software behavior at the method/function level, then be extended for functional testing and automatically configured for regression testing. For safety-critical work, this extends to system-level testing with fault injection, letting teams verify functional correctness under both normal and fault conditions to help meet standards like ISO 26262 and DO-178B/C.

Parasoft C/C++test provides runtime analysis capability to address the reliability and stability side of performance concerns.

Parasoft C/C++test is a unified testing solution that combines static analysis, unit testing, code coverage, runtime analysis, requirements traceability, and compliance reporting into a single integrated platform for C and C++ development. Rather than stitching together separate tools, it fits into existing IDEs (VS Code, Eclipse) and CI/CD pipelines, letting teams catch defects, security vulnerabilities, and standards violations earlier while automating much of the manual testing and compliance overhead. It's TÜV SÜD-certified for functional safety standards including ISO 26262, IEC 61508, IEC 62304, and DO-178B/C, and increasingly incorporates AI-driven and agentic workflows — via an MCP server and AI-assisted test generation — to accelerate test creation and coverage. In short, it positions itself less as a single-purpose tool and more as an end-to-end testing backbone for safety- and security-critical embedded C/C++ development.

Parasoft C/C++test's static analysis engine catches security vulnerabilities before code runs, applying pattern-based analysis, data flow analysis, and abstract interpretation against standards like CERT C/C++, CWE, and OWASP. The 2025.1 release added nearly 70 new static analysis rules targeting CWEs specifically to help developers quickly identify vulnerabilities and optimize security. Analysis integrates directly into IDEs like VS Code and Eclipse and into CI/CD pipelines, surfacing issues at commit/build time, alongside coding-standard enforcement (MISRA C:2025, MISRA C++:2023, AUTOSAR C++14) for industries where security and compliance go hand in hand.

Parasoft C/C++test's core static analysis combines pattern-based analysis, data flow analysis, abstract interpretation, and metrics to detect defects, security vulnerabilities, and standards violations without executing the code. It enforces coding standards such as MISRA C:2025, MISRA C++:2023, AUTOSAR C++14, CERT C/C++, and CWE, and integrates directly into IDEs like VS Code and Eclipse and into CI/CD pipelines, so violations surface early, right where developers are working. Results can also be correlated with runtime and unit test findings in Parasoft DTP for a fuller picture of code quality.

Parasoft C/C++test provides a built-in, end-to-end unit testing framework that automatically generates tests, mocks, stubs, and assertions to isolate the unit under test, and detects failures, unsatisfied expectations, and coverage gaps in real time during execution. Tests can be created via graphical editors, guided workflows, and the Test Case Explorer, and run on host, simulator, or target hardware to meet safety-critical requirements. Unlike tools that store test inputs in proprietary formats, C/C++test generates test cases as source code, with parameter values initialized the same way as in production, keeping tests reviewable and version-controllable. It also integrates with open-source frameworks like GoogleTest, Boost.Test, and CppUnit to add structural coverage (statement, branch, MC/DC), reporting, and CI/CD automation.
