### build & test jobs



You can specify if you want the template to build an `application` or `modules` with the `GO_BUILD_MODE` variable. It may have the following values: 



 * `application` will make the build output the binaries (use `-o` build option, won't work if there is no `main.go` file)

 * `modules` won't output the binaries (no use of the `-o` option)

 * `auto` the template will rely on the presence of a `main.go` file to detect if it should output the binaries.
