CI STB System (Tata Elxsi):

Role: Team Lead and Senior Developer.

Project Description:

• The CI STB System consists of three major components: Jenkins, CI Portal, and Test Manager. Jenkins is used for triggering builds, and the build status is sent to the CI Portal, whether it is passed, failed, or aborted. The CI Portal has a dashboard for showing the build status, and doughnut charts are used for displaying various statistics related to builds. When there is a build success in Jenkins, then the CI Portal notifies the Test Manager to run some pre-configured test scripts in STBs, which are placed in Falcon racks. After the completion of tests on devices, the overall status and test execution status are sent to the Test Manager, where the user can see a more detailed view of test execution, along with logs and steps. In the final step, the overall build test status is sent to the CI Portal again.
