Demo repo to showcase code coverage when using Go.

Go Code Cove

A very quick and dirty demonstration of how to use code coverage when testing with Go.

Getting started

Clone this repository down into your preferred working directory:

gh repo clone damiensedgwick/go-code-cove

Run the following command to run the tests and create a cover.out file

go test -coverprofile cover.out

Lastly, run this command to open cover.out in your default browser

go tool cover -html=cover.out

What to expect

After you have cloned the repository and ran the first test command, you should see the following output in your terminal:

go test -coverprofile cover.out
PASS
coverage: 66.7% of statements
ok  	github.com/damiensedgwick/code-cov	0.266s

Then when you run the second command to open the report in your browser, you should see the following:
