Can someone explain pls why the Promise returns pending in the first function, but resolved in the other two?

Can someone explain pls why the Promise returns pending in the first function, but resolved in the other two? When i read MDN it states that just using the word async wont make the code inside asynchronous (we need to use the word await as well). Also, I return the promise explicitly, since I use resolve() (which should return fulfilled promise as in two other functions, yet it returns Pending in the first function). I provided the code below.

const testFunc = async() => {
  return new Promise((resolve,reject)=> {
    resolve()
  })
}

const testFunc2 = () => {
  return new Promise((resolve,reject)=> {
    resolve()
  })
}

const testFunc3 = () => {
  return new Promise((resolve,reject)=> {
    resolve()
  })
}

testFunc().then(()=> console.log("Hello")).then(()=> console.log("there")).then(()=> console.log("Obi One"))

testFunc2().then(()=> console.log(1)).then(()=> console.log(2)).then(()=> console.log(3))

testFunc3().then(()=> console.log(4)).then(()=> console.log(5)).then(()=> console.log(6))

console.log(testFunc())
console.log(testFunc2())
console.log(testFunc3())

Results in the console: 
Promise {<pending>}
Promise {<fulfilled>: undefined}
Promise {<fulfilled>: undefined}
