Your tests should be passed in such CI services always because you have made sure your codebase passes the tests before pushing. However, .travis.yml, the configuration file of Travis, sometimes has bugs and your dependency list sometime loses any libraries. To evaluate those tests locally, I made Loci, which runs tests in a sandbox based on Docker. https://www.jkawamoto.info/blogs/get-logs-from-stackdriver-logging/ Mon, 02 Jan 2017 00:00:00 +0000 junpei.kawamoto@acm.org (Junpei Kawamoto) https://www.jkawamoto.info/blogs/get-logs-from-stackdriver-logging/ In order to obtain log data from Google Cloud Platform, using the Stackdriver client which logadmin package provides is one of the easiest ways.
