Studying the e-book Test-driven development with Go by Yigal Duppen

Enter the repository's root directory and run

go run qrcoded.go

If this repository is checked out in a directory structure organized accordingly to the standard described in the official documentation, the go tool can be used to install and test the code.

In order to build the code, run

go install github.com/golang4dummies/golang-tdd

This will compile the package and generate an executable in $GOPATH/bin.

Alternatively, you can cd into the repository's root with

cd $GOPATH/golang4dummies/golang-tdd

and then simply run

go install

Note that the executable will be named after the repository name, not the Go file.

Install the package, then run it with

$GOPATH/bin/golang-tdd

If $GOPATH/bin has been included in $PATH, as suggested in the official documentation, you can simply run the program with

golang-tdd

Run

go clean -i
