save/test/delete.js

A simple CRUD based persistence abstraction for storing objects to any backend data store. eg. Memory, MongoDB, Redis, CouchDB, Postgres, Punch Card etc.

module.exports = function(idProperty, getEngine) {
  describe('#delete()', function() {
    it('should delete the entity', function(done) {
      getEngine(function(ignoreError, engine) {
        engine.create({ a: 1 }, function(ignoreError, insertedObject) {
          engine.delete(insertedObject[idProperty], function(error) {
            ;(error === undefined).should.equal(true)
            engine.find(insertedObject, {}, function(ignoreError, objects) {
              objects.length.should.eql(0)
              done()
            })
          })
        })
      })
    })

    it("should emit a 'delete' event", function(done) {
      getEngine(function(ignoreError, engine) {
        engine.create({ a: 1 }, function(ignoreError, insertedObject) {
          engine.on('delete', function(entity) {
            entity.should.eql(insertedObject[idProperty])
            done()
          })
          engine.delete(insertedObject[idProperty])
        })
      })
    })

    it("should emit a 'afterDelete' event", function(done) {
      getEngine(function(ignoreError, engine) {
        engine.create({ a: 1 }, function(ignoreError, insertedObject) {
          engine.on('afterDelete', function(entity) {
            entity.should.eql(insertedObject[idProperty])
            done()
          })
          engine.delete(insertedObject[idProperty])
        })
      })
    })
  })
