Low-overhead coverage analysis for critical software
Why choose RapiCover?
Collect coverage for Ada, C & C++ (inc. MC/DC) on-host & target
By automating code instrumentation and coverage collection, RapiCover reduces the effort needed to verify your code coverage up to and including MC/DC. Flexible integration strategies ensure efficient verification, regardless of your target hardware.
RapiCover measures code that other tools don’t, such as treating Boolean and bitwise operators as decisions, and lets you test decisions with up to 1000 conditions.
Reduce test builds needed for analysis on constrained targets
RapiCover’s low target overheads help you cut the number of builds you need for coverage analysis on even the most constrained systems. With flexible integration strategies, RapiCover lets you fit more tests on target whether your RAM, code size or execution time are constrained.
Save time with efficient merge and mark verification workflow
Reduce your testing effort through an efficient verification workflow. Collect coverage from system tests, automatically merge this with coverage from integration and unit tests, and mark any remaining coverage holes as covered by analysis using RapiCover justifications.
This workflow is ideal for DO-178C testing even when your code changes as RapiCover helps you review which of your coverage results and justifications need to be changed.
Simplify verification through integration with your continuous integration tool
Keep your verification on track by using RapiCover alongside your continuous integration tool. Collect coverage results and track your project’s progress over time with our plugins for Jenkins and Bamboo.
By analyzing your code with RapiCover on every new build, you can easily identify anomalies in your code coverage as they happen.

Frequently asked questions
How do I learn more about RapiCover?
If you're interested in RapiCover in academia, you can search for it in the academic press.
What is RapiCover?
RapiCover is the leading tool for structural code coverage analysis of critical software.
Used globally in the aerospace and automotive industries, it reduces the cost of analyzing structural code coverage analysis up to and including MC/DC.
As part of the RVS toolsuite, it forms part of a software verification solution that also includes tools for functional testing and worst-case execution time analysis.
How does RapiCover work?
RapiCover works by injecting instrumentation code into source code and executing the native build system so that coverage results are collected during program execution. Data can be collected from almost any target hardware by a variety of approaches.
Which host operating systems can RVS be used on?
RVS tools support Windows 7 or newer, Windows Server 2008 R2 or newer, and a variety of Linux distributions including Ubuntu and Red Hat.
RVS tools can be used on projects with unsupported operating systems by using a clone integration to split the process and delegate parts of it to the unsupported machine.
Which hardware architectures do RVS tools support?
RVS tools can be integrated to work with almost any embedded target. Our engineers can work with you to determine the optimal strategy for integrating the tool with your target, even for multi-core architectures. For more information on the hardware architectures we have integrated RVS tools with, see the compatibility information on our RVS product pages.
Can I use RapiCover with my build system?
RapiCover can be integrated to work with almost any compiler and target hardware. Our integration service promises to deliver a robust integration of RapiCover into your build system.
Which languages does RapiCover support?
RapiCover supports C, C++ and Ada projects, including mixed-language ones.
My software is part of a product that must be certified against a safety guideline. Can RapiCover be qualified for use in my project?
RapiCover is designed to meet the most stringent needs of certification processes, such as the DO-178B/C process used in the aerospace industry and the ISO 26262 process used in the automotive industry. We can provide developer qualification documents, a template integration qualification report and on-site tests to support you in qualifying RapiCover tools in projects requiring certification.
Can I collect coverage data across power cycles and reset sequences?
RapiCover can be configured to collect data in real-time while your software runs. By writing data to an external device, the data will remain in place while your system reboots, and collection can be reinitialized when it restarts. This means that you can collect coverage data across a shutdown or reset sequence. This is subject to your target hardware architecture.
Can I determine coverage for a decision containing large numbers of conditions?
By default, RapiCover supports 30 conditions per decision, and includes support for up to 1000 conditions per decision using an alternate, inbuilt instrumentation strategy.
Can I collect coverage over multiple builds?
Using our configurable instrumentation mechanism, you can instruct RapiCover to determine coverage for specific subprograms as necessary. After running your tests, it’s easy to merge coverage data from these runs into a combined report using RapiCover’s Merge Coverage utility.
Which coverage criteria can I measure using RapiCover?
You can measure the most common coverage criteria required to support DO-178B/ED-12B, DO-178C/ED-12C and ISO 26262 certification using RapiCover. This includes function, call, statement, branch, decision and condition coverage, and MC/DC.
How large a code base can RVS tools handle?
RVS tools are designed to handle very large code bases. Because of the efficient algorithms used by RVS tools, there is no fundamental limitation to the number of lines of code that RVS can process, and our RVS tools have been used on projects with millions of lines of code.
How are RVS products licensed?
We offer both “Node-locked” and “Floating” licenses, and a license server to support use of our tools in your specific development environment. Floating licenses follow the “Enterprise” model, meaning that you can use our tools across geographical boundaries* and different projects and users.
For more information on our licensing models, see our RVS licensing FAQs.
What happens if I encounter an issue while using an RVS tool?
All RVS licenses include access to our dedicated in-house support team, who will work with you to provide a rapid fix to your issue. This is a critical part of our vision. During 2016, we responded to 97% of new support requests within one working day, closed 56% of these within 3 working days and 91% within 20 working days. We also inform our customers of known issues via our website and email.
How do you support RVS users?
We provide an extensive set of RVS documentation with each of our products, and offer training courses guiding you through the most effective use of RVS tools. All our users can benefit from privileged access to our website, which includes downloads for new product releases.
Can I add manual configurations that flag my code as being exempt/uncoverable?
RapiCover and RapiCoverZero include a powerful “justification” mechanism that lets you mark code as covered. Using this feature, you can provide a rationale for justifying the code and create templates to justify code more easily. When your code changes, justifications are automatically migrated to represent the new location of your justified code.
What happens when I change my code?
RapiCover and RapiCoverZero retain information about the revision of your code it used to generate results. The tool will report an error if you try to merge coverage from incompatible revisions. RapiCover includes an Optimal Dataset Calculator feature you can use to calculate the least expensive tests you need to run again when your code changes, saving you valuable testing effort.
How is my data presented?
All RVS tools include a friendly user-interface that presents your data in both tabular and graphical formats. Using this interface, you can filter your results to zoom in on target functions, making it easy to find the information you are looking for.
Treemaps provide a high-level overview of your code base and help you understand the coverage of your code at a glance.
Can I use RVS tools with my continuous integration environment?
RVS integrates with continuous integration tools including Jenkins and Bamboo. By integrating RVS with your existing continuous integration tool, you can collect unit test, coverage, and execution time results with every new build, letting you easily identify anomalies in your software’s behavior as they happen.
How do I verify my software’s functional and temporal behavior when instrumentation has been applied?
We recommend that, when performing functional testing of safety-critical applications for a final run-for-score, you run your full test suite both with and without coverage instrumentation applied, then confirm that the results match. This provides evidence that RVS instrumentation has not changed the functional behavior of your code.
How long has RVS been used for software verification?
The Rapita Verification Suite (RVS) has been used in the critical embedded industry for over 15 years and supported a number of avionics projects globally. Qualification kits for qualified RVS products have supported more than 20 DO-178B and C certification projects up to and including DAL A.
Can I collect RapiCover results from tests run by a third-party test framework?
Yes, you do not need to use RapiTest to collect coverage results. RapiCover can instrument your test code so coverage results can be automatically collected as your tests as run, then displayed for analysis.
