chai javascript code example
Example 1: mocha js
Mocha is a JavaScript test framework!
var assert = require('assert');
describe('Array', function () {
describe('#indexOf()', function () {
it('should return -1 when the value is not present', function () {
assert.equal([1, 2, 3].indexOf(4), -1);
});
});
});
Example 2: chai js
Chai is an assertion library with 3 different assert styles,
namely "should", "expect" and "assert".
foo.should.equal('bar');
expect(foo).to.equal('bar');
assert.equal(foo, 'bar');
It can be used to replace the default assertion styles of JavaScript testing frameworks.
