Example .travis.yml for Golang

.travis.yml

# use the latest ubuntu environment (18.04) available on travis
dist: bionic

language: go

# You don't need to test on very old versions of the Go compiler. It's the user's
# responsibility to keep their compiler up to date.
go:
  - 1.16.x

# Only clone the most recent commit.
git:
  depth: 1

# Skip the install step. Don't `go get` dependencies. Only build with the code
# in vendor/
install: true

# Don't email me the results of the test runs.
notifications:
  email: false

# Anything in before_script that returns a nonzero exit code will flunk the
# build and immediately stop. It's sorta like having set -e enabled in bash.
# We can download and extract the golangci-lint binary in one (long) command.
before_script:
  - curl -sSfL https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh | sh -s -- -b $(go env GOPATH)/bin v1.37.1

# script always runs to completion (set +e). If we have linter issues AND a
# failing test, we want to see both. Configure golangci-lint with a
# .golangci.yml file at the top level of your repo.
script:
  - golangci-lint run       # run a bunch of code checkers/linters in parallel
  - go test -v -race ./...  # Run all the tests with the race detector enabled

@akash355 The error message is pointing to a missing Rakefile, so I don't think that has anything to do with Go. Are you using Ruby in your project? This .travis.yml file is only for Go projects.

I would debug this by inserting ls commands into your .travis.yml at a point prior to the failure. It will show you what files are present on the Travis CI runner. Good luck!
