Design and perform unit testing for your embedded software
Quality verification services based on GAIO’s own embedded code and MPU technologies
Create unit test guidelines and reports according to customer requirements


Embedded software unit testing services

As part of GAIO unit testing services, we create test cases from customer’s software design documents or source code, and then perform unit testing using GAIO’s own professional unit test tool, CoverageMaster winAMS. Thorough documentation regarding unit test design, results and errors encountered will be presented to the customer. In addition, we can also asses the target software quality and make improvement suggestion by request.

Unit Test Service Flow

After signing NDA documents, GAIO will analyze the customer’s source code and provide an estimation for unit test costs and delivery date. Once the customer gives us the okay to begin, we will perform the unit testing for customer’s embedded software. When completed, we will send to the customer the unit test documentation and results including the test environment files that were used.

Error Detection Examples

Conflicts between function specification and source code
Dead code (example :control paths with conditions that will not be achieved)
Infinite loop
Division by Zero
NULL pointer access
Overflow, underflow
Array overrun, illegal access
Uninitialized local variable
Compiler error
C code implementation error (example: implicit cast, wrong data type)
Errors caused by recursive function calls
Illegal memory access (example: data write to read only memory)


Cost/Date Estimation

The unit test cost and delivery date will be estimated based on function complexity as reported from source code analysis. GAIO will perform the source code analysis if source code can be sent under NDA agreements. Otherwise, our estimations will be based on source code analysis results from CasePlayer2 performed by the customer.
