Why can't I new a object in ES6?

I'm learning ES6, I wrote the test code like below:

// export.js:
class Test {
    constructor() {
        console.log('teste5ty')
    }
}

class Test2 {
    constructor() {
        console.log('test2')
    }
}
export {Test, Test2}
export default Test

another export file code is below:

// test2.js
class Teste3 {
    construct() {
        console.log('heheheheh')
    }
}
export default Teste3

finally, test code as below:

import Test from './export'
import {Test2} from './export'
import Teste3 from './test2'

new Test()
new Test2()
new Teste3()

after transforming to es5 by Babel, I got the output like below:

teste5ty
test2

Apparently, Test3 is not instantiated, why this happens??
