gl-material-test

Test your 3d materials!

This module provides a test function for validating that a material conforms to the definition in gl-material. It creates a gl context, makes sure that your material can generate a compiled shader, and has valid styles and defaults.

install

Add to your project with

npm install gl-material-test

example

Test a material by providing it alongside a test module like tape or tap

var test = require('tape')

var material = {
  fragment: `precision highp float;\ 
    struct Style {\
      vec3 color;\
    };\
    uniform Style style;\
    void main() {\
      gl_FragColor = vec4(style.color, 1.0);\
    }`
  style: {
    color: {type: 'vec3', default: [0, 100, 0]}
  },
  name: 'my-flat-material'
}

require('gl-material-test')(test, material)

If you put this inside a file test.js, you can run the tests by browserifying it and piping it to anything that runs tests in the browser like testron. For example, your full test script could be browserify test.js | testron | tap-spec.

usage

require('gl-material-test')(test, material, [constants])

Provide a test module like tape or tap, and a material that conforms to the definition in gl-material. Optionally provide an object of constants for performing string replacement. If your material doesn't use this feature, leave this argument out.
