Continuous Integration (CI) in conjunction with Continuous Testing (CT) is indispensable for obtaining immediate quality insights in software development. For a software-defined vehicle, they are essential as they enable early detection of issues in code from units to end product and continuous improvement of software.
Continuous Integration, combined with a cloud-based approach, can significantly accelerate extensive test suites. Test results are thus available in hours rather than days - without compromising the meaningfulness.
With TPT, a powerful tool supports you in automating tests within the CI/CT process and integrating cloud resources for shorter test execution times.
Continuous Integration
With the Continuous Integration (CI) approach, it's possible to check early and continuously during development whether changes in the code lead to issues. Code changes are regularly integrated into a shared file version control system, commonly referred to as a repository.
Continuous Testing complements CI: Automated tests are embedded into the integration process to ensure that each code change delivers the expected results and does not cause regressions.
Supported CI Environments
TPT can be integrated into all CI environments via the TPT API or through the Command Line Interface.
Examples include Jenkins, Bamboo, TeamCity, or Azure DevOps Server. Additionally, there is a dedicated plug-in available for Jenkins.
Supported file version control
The TPT Project format, a machine-readable XML format, is suitable for all types of repositories to track changes to the test. Because TPT projects and data reside in the file system, it allows for easy and flexible information transfer depending on the system used.
Examples include Git, Subversion, or SharePoint.
Cloud Testing
Software tests are typically executed on local computers, which can lead to long execution times for large models or extensive tests. To accelerate test processes, the use of cloud solutions is recommended.
Advantages of using TPT in the Cloud
Accelerated Test Execution: In the cloud, computing units can be virtually cloned and instantiated in parallel, enabling horizontal scaling. Parallel test execution significantly reduces the duration of testing.
Efficient Resource Utilization: Cloud solutions enable efficient resource utilization by dividing tests across various virtual instances and executing them independently. This maximizes the utilization of computing resources and speeds up the testing process.
Flexibility and Scalability: The cloud offers the flexibility to adjust test environments and scale resources according to demand. This allows for agile adaptation to changing requirements and peak loads during the testing process.
Recommendations for Cloud Testing
Clarity
It is important to have a clear overview of the products being used and their interactions. Detailed documentation of the products being used and their functionalities is essential.
IT competence
When establishing a cloud testing infrastructure, IT expertise is more crucial than expertise in the subject matter of the test object.
A fundamental understanding of cloud technologies and tools is essential for the successful setup and operation of the testing environment.

Overall, utilizing TPT in the cloud offers numerous advantages for test automation and execution in the automotive industry. By leveraging cloud-based solutions, test execution times can be shortened, feedback loops accelerated, and costs for test infrastructure reduced, ultimately leading to a shortened time-to-market for software-based vehicle functions.
