    Obtained functional safety standards

    We have obtained tool certification for ISO 26262 (TCL1 to TCL3) and IEC 61508 from TÜV SÜD, a third-party certification organization.

  • Features 2

    Cloud environment available

    Cloud environment available

    QTE is available in a Cloud environment that allows for a rapid development environment. By utilizing containers and K8S, QTE provides a flexible and scalable development environment.

  • Features 3

    Efficiently transfer OSS test tool assets to functional safety standards

    Efficiently transfer OSS test tool assets to functional safety standards

    In recent years, software has been developed in a continuous integration style, based on open source software (OSS) development platforms in order to accommodate the increasing scale and complexity of software. However, the general OSS environment makes it difficult to conduct functional safety level testing, leading to an increase in man-hours required to conduct in-vehicle quality testing. QTE can efficiently adapt assets from Google test, an OSS testing tool, to meet functional safety standards.

  • Features 4

    In-vehicle quality testing can be easily performed even by inexperienced embedded engineers.

    In-vehicle quality testing can be easily performed even by inexperienced embedded engineers.

    For non-embedded engineers, conducting in-vehicle quality testing is challenging due to the use of tools specific to in-vehicle software, resulting in increased test execution man-hours. QTE makes it easier for inexperienced engineers to conduct in-vehicle quality testing.

Functions of QTE

  • Function1

    Two execution modes to suit your testing process

    Non-embedded engineers can also efficiently conduct testing

    QTE offers two test execution modes: Native execution mode, which executes as PC-Native code, and Target execution mode, which executes microcontroller target code. Efficient test execution is possible for each test process by using PC-Native execution mode for high-speed test design and code coverage measurement, and using Target execution mode when functional safety level test execution is required.

    01

    Two execution modes to suit your testing process

  • Function2

    Code coverage measurement functionality

    Two types of coverage functions, GCC Coverage Function and Functional Safety Coverage Function, are provided.

    As with the test execution mode, they can be used in different ways according to the test process to achieve efficient test execution.

    The Functional Safety Coverage function measures statement coverage (C0), branch coverage (C1), MC/DC coverage, function coverage, and function call coverage.

    02

    Code coverage measurement functionality

  • Function3

    Testing is possible on all data types for C++ Templates.

    Measurement of execution coverage of multiple objects for Template

    In-vehicle quality testing requires object-level execution coverage, but Template generates multiple execution objects for each type from a single source, so even if code coverage is measured for each class, it does not cover all execution objects.
    QTE enables code coverage measurement for each Template type, which is not possible with OSS tools.

    03

    Testing is possible on all data types for C++ Templates.

  • Function4

    Supports a variety of target test execution environments

    POSIX-OS equipped, available in OS-less target environment

    Tests can be executed using MPU target objects generated by the cross-compiler. The target environment can be an actual device (evaluation board or real product hardware) or a microcontroller simulator.
    In addition, QNX and embedded Linux are supported as target environments with POSIX-OS. In addition, targets without POSIX-OS or OS-less (bare-metal) target environments can also be used.

    04

    Supports a variety of target test execution environments

  • Function5

    Generate reports for each stakeholder in Agile/Scrum development

    Enhanced reporting functions

    Equipped with a report function that integrates test results.
    Previously, it was necessary to separately integrate and check the test results conducted by each team, but with this function, it is now possible to efficiently check the progress management of the entire final product source code.

    05

    Generate reports for each stakeholder in Agile/Scrum development

  • Function6

    Support for distributed/parallel test operations

    Merges multiple code coverage results and reports comprehensive results

    Code coverage results from multiple Google Test drivers can be merged, making it easy to understand the code coverage rate and unexecuted test coverage for the each team or the entire product.

    Enables flexible test execution planning and work sharing
    Tests can be distributed and parallelized to reduce test execution time. In addition, it is also possible to augment and supplement the unexecuted portions of tests with additional testing in other projects.

    06

    Support for distributed/parallel test operations

  • Function7

    Provides QTE reference workflow (safety manual)

    The reference workflow explains the specific use of QTE to develop safety-related software compliant with the base standards IEC 61508 and ISO 26262.

    The workflows for unit and integration testing in relation to the content of ISO 26262 Part 6 (product development at software level), how to create test cases using Google Test, as well as how to evaluate test results and analyze structural coverage are explained in detail. The book also provides detailed information on how to evaluate test results and perform structural coverage analysis.

  • Function8

    Streamlining Unit Testing with VS Code Integration / AI Agent Integration

    • Perform Unit Test Operations Within VS Code

    Integration between VS Code and QTE streamlines the entire development workflow—from coding and reviewing test results to modifying source code and adding test cases.

    In addition, a dedicated view in VS Code allows you to check the logical combination patterns required for MC/DC coverage (total patterns) alongside actual test execution results (executed patterns). Missing patterns can be identified at a glance, making it easy to add test cases to the Google Test driver.


    • Integration with AI Agent

    Streamline coverage achievement through integration with an AI Agent.
