This package is a development in progress. Pull requests are welcome.
Current assertions implemented so far are value eq
, value deep eq
, value null
and value undefined
assertions:
value.to.eq
, value.to.deep.eq
Examples:
describe(`Scalar`, () => {
it(`should equal value`, () => {
expect(new y.Scalar('hello')).value.to.eq('hello')
expect(new y.Scalar('hello')).value.to.eq(new y.Scalar('hello'))
expect(new y.Scalar(null)).value.to.eq(null)
expect(new y.Scalar(undefined)).value.to.eq(undefined)
expect(new y.Scalar('')).value.to.eq('')
expect(new y.Scalar('')).value.to.eq(new y.Scalar(''))
})
})
describe(`Pair`, () => {
it(`should equal value`, () => {
expect(new y.Pair('hi', 0)).value.to.eq(0)
expect(new y.Pair('', 0)).value.to.eq(new y.Scalar(0))
expect(new y.Pair('hi', 1)).value.to.eq(1)
expect(new y.Pair('apple', 1)).value.to.eq(new y.Scalar(1))
expect(new y.Pair('apple', null)).value.to.eq(null)
expect(new y.Pair('hi', null)).value.to.eq(new y.Scalar(null))
expect(new y.Pair('hi', 'hello')).value.to.eq('hello')
expect(new y.Pair('hi', 'hello')).value.to.eq(new y.Scalar('hello'))
expect(new y.Pair('hi', '0')).value.to.eq('0')
expect(new y.Pair('hi', '1')).value.to.eq(new y.Scalar('1'))
expect(new y.Pair('hi', 'false')).value.to.eq(new y.Scalar('false'))
expect(new y.Pair('hi', false)).value.to.eq(new y.Scalar(false))
// expect(new y.Pair('hi', undefined)).value.to.eq(undefined)
// expect(new y.Pair('hi')).value.to.eq(undefined)
})
