We have updated our pipeline by using the latest version from:
https://github.com/SAP/cloud-s4-sdk-pipeline
But neither the test results nor the test coverage reports of the frontend unit tests could be found.
Could anyone help?
The directory where the tests are has changed to s4hana_pipeline/reports/ recently. Please update your karma.conf.js file as described in https://blogs.sap.com/2017/09/19/step-12-with-sap-s4hana-cloud-sdk-automated-testing/.
