The cadence changed
Short cycles and continuous integration are now normal for safety-critical work. Testing has to run at that cadence, not at the end of a milestone.

The challenge
Testing can't wait for the end of the cycle.
Safety-critical software is increasingly built like modern software — short cycles, continuous integration. Testing has to keep that pace, or it becomes the thing everyone waits on.
Manual testing doesn't scale
Manual and semi-automated testing can't match commit frequency. Slow feedback lets a defect ripple downstream before anyone sees it.
A result off the pipeline isn't trusted
A result produced by hand, outside the pipeline, is hard to reproduce and hard to trust. Evidence for the standards has to come from the pipeline itself.
The solution
A full test and verification suite, built into the pipeline.
BTC TestStack runs MIL, SIL and PIL testing directly in your CI/CD pipeline, unattended — producing the traceable evidence ISO 26262 and related functional-safety standards expect.
The same suite you run locally runs in the pipeline, on every commit.
Runs in the pipeline
- Requirements-based, back-to-back and regression tests
- Code coverage analysis and automatic test generation for structural coverage
- Dead-code analysis
- Formal test and formal verification
- Migration tests across tool and compiler versions
Fits your CI/CD toolchain
Connect it to the pipeline you already run.
Support for all common CI environments, a versatile REST API, and an MCP server for pipelines driven by AI agents.

REST API
OpenAPIThe API follows the OpenAPI standard, enabling client libraries to call it from the language your pipeline is written in.

MCP
AI agentsFor pipelines where AI agents take decisions and control the process. BTC TestStack exposes its capabilities through an MCP server, so an agent can run tests, read the results, and decide the next step.
Python skill
coding agentsUsing Python? Drop our skill into any coding AI agent and it writes the pipeline script for you — just describe your workflow in natural language.
Scalable
Scale the test backend to your workload.
Run the backend wherever you need capacity — scale out for large test suites, keep environments consistent, and control cost.
Virtual machines
Run the backend on virtual machines, in the cloud or on premise — familiar operations, capacity where you want it.
Linux Docker containers
Run in Linux Docker containers, in the cloud or on premise — installation-free and reproducible, the same image every run.
BTC TestStack × Cloud
The fully cloud-native option: a scalable AWS backend and a browser-based frontend, with no local installation.
Built for modern development
CI/CD/CT — the backbone of modern development.
BTC TestStack is built for the principles a modern pipeline runs on — not bolted onto them afterward.
Fast feedback
Actionable results in minutes — and the same tests run locally and in the pipeline.
Traceability
Results link every artifact to a commit and through to requirements — supporting ISO 26262, related standards and ASPICE.
Everything as code
Test definitions, expected results and coverage goals are codified and versioned — ideal for Git-based workflows.
Continuous Testing (CT)
Testing shifts left and runs at every stage, evolving with the software as it changes.
Related use cases
What runs in the pipeline.
Use case
Back-to-Back Test
Back-to-back tests between model and code are highly recommended by the ISO 26262 standard.
Use case
Regression Test
Regression tests between different versions of a software play an important role in A-SPICE and ISO 26262.
Use case
Migration Test
Ensure that new tool versions don't introduce unintended changes in the behavior of your software!
Use case
Code Coverage
In BTC TestStack, code coverage is automatically calculated and updated in the background.
Use case
Automatic Test Generation
Reach full structural coverage and turn requirements into test cases — generated automatically.
Use case
Requirements-Based Testing
Requirements-based testing for Simulink, TargetLink, Embedded Coder, handwritten and AI-generated code.
