Ogma can work with the most testing frameworks out there. But in order to make it run in headless mode, you need to make the node-canvas or canvas-prebuilt library available to it, to mock the rendering.

Mocha

 npm install --save-dev mocha chai canvas
 mocha tests/**/*.test.js

const Ogma = require('@linkurious/ogma');
const { assert } = require('chai');

describe ('dummy suite', () => {

  it ('dummy test', () => {
    const ogma = new Ogma();
    return ogma.setGraph({
      nodes: [{ id: 0 }, { id: 1 }],
      edges: [{ source: 0, target: 1 }]
    }).then(() => {
      assert.equal(ogma.getNodes().size, 2);
    });
  });
});

Jest

 npm i --save-dev jest canvas
 jest

Alternatively, you can use other canvas-mock library, like jest-canvas-mock, and set it up to be included in the setup.

const Ogma = require('@linkurious/ogma');

describe ('dummy suite', () => {

  test ('dummy test', () => {
    const ogma = new Ogma();
    return ogma.setGraph({
      nodes: [{ id: 0 }, { id: 1 }],
      edges: [{ source: 0, target: 1 }]
    }).then(() => {
      expect(ogma.getNodes().size).toBe(2);
    });
  });
});

Jasmine

 npm i --save-dev jasmine
 jasmine

const Ogma = require('@linkurious/ogma');

describe ('dummy suite', () => {

  it ('dummy test', () => {
    const ogma = new Ogma();
    return ogma.setGraph({
      nodes: [{ id: 0 }, { id: 1 }],
      edges: [{ source: 0, target: 1 }]
    }).then(() => {
      expect(ogma.getNodes().size).toBe(2);
    });
  });
});
