Firmware Testing Services for Embedded & IoT Devices

Why firmware testing is difficult

Behavior depends on device state

The same firmware can act differently after a reset, a long uptime or an interrupted operation.

Failures appear under specific configurations

A build that passes on one configuration can fail on another.

Timing and resource limits change the result

Memory, CPU and timing constraints on the target can turn a correct path into a failing one.

Interfaces affect behavior

Hardware and communication interfaces shape what the firmware actually does.

Reproduction needs the original setup

To see the same failure again, the conditions it happened under have to be preserved.

What firmware testing covers

Firmware behavior

Validate execution paths, state transitions and failure conditions across relevant firmware configurations.

Memory and resource behavior

Investigate issues involving memory usage, resource limits and low-level system behavior.

Device state and configuration

Reproduce firmware behavior under different device states, configurations and operating conditions.

Communication interfaces

Test firmware behavior across device, network and peripheral interfaces.

Update and version changes

Compare behavior across firmware versions and verify that changes do not introduce new failures.

Midair

How Midair handles firmware testing

1

Analyze the firmware

Visao

Visao identifies code-level findings, execution paths and project-specific rules before execution.

2

Reproduce the firmware scenario

TS Factory

TS Factory runs the relevant firmware on the target device or test environment with the required configuration.

3

Capture runtime evidence

Delta

Delta collects logs, events, resource data and other runtime evidence while the scenario runs.

4

Keep the investigation connected

Midair

Midair links the code finding, firmware version, test conditions and runtime evidence so the same scenario can be investigated again.

When firmware testing matters

Before a firmware release

Validate changes before they reach deployed devices.

After major firmware changes

Check whether updates introduce new failures or change existing behavior.

Across device configurations

Test behavior that depends on hardware, configuration or operating conditions.

When failures are difficult to reproduce

Preserve the conditions and evidence needed to investigate the same scenario again.

FAQ

What is firmware testing?

Firmware testing verifies that embedded software works reliably with hardware under real operating conditions.

Why is firmware testing important?

Because many firmware failures appear only after deployment, when devices face real environments, unexpected inputs, and long operation cycles.

Can Midair be used before target hardware is available?

Visao can analyze firmware source code without executing it. Runtime and device-level testing depend on the environment available for the project.

How is firmware testing different from software testing?

Firmware testing focuses on the interaction between software and physical components, including timing, resources, and hardware limitations.
