// Tests are separated into 3 steps.
|
|
//
|
|
// Run all tests with `go test` or run specific tests with the -tags option.
|
|
// Examples,
|
|
//
|
|
// go test # run all tests
|
|
// go test -tags step1 # run just step 1 tests.
|
|
// go test -tags 'step1 step2' # run step1 and step2 tests
|
|
//
|
|
// This source file contains step 1 tests only. For other tests see
|
|
// robot_simulator_step2_test.go and robot_simulator_step3_test.go.
|
|
//
|
|
// You are given the source file defs.go which defines a number of things
|
|
// the test program requires. It is organized into three sections by step.
|
|
//
|
|
// To complete step 1 you will define Right, Left, Advance, N, S, E, W,
|
|
// and Dir.String. Complete step 1 before moving on to step 2.
