Test karel submissions from codehs using jskarel

coverage:

Usage

Test File syntax

Module should export these objects:

• config with karel starting position
• list of assertions. Function of karel, returning a chai test case

Example

This file checks that karel moved one position north and one position west, and picked up the beeper there

const { expect } = require('chai')

const startingX = 2; // can generate a random number instead

module.exports.config = {
    karel: {
        position: [startingX, 2]
    },
    world: {
        beepers: [[startingX + 1, 3]]
    }
}

module.exports.assertions = [
    karel => expect(karel.position).eql({x: startingX + 1, y: 3}, 'karel should finish on 3x3'),
    karel => expect(karel.world.beepers).length(0, 'all beepers should be picked up')
]

As a cli program

Output is a json representation of results (test name with )
