TypeScript Expected 1 arguments, but got 2

December 15, 2021

What’s wrong with my function createUser()?
Why I can’t put params in Smoke.ts ?

interface User {
  url: string,
  email: string,
}

class Test{ 
async createUser(user: User) {
    await Page.setUrl(user.url);
    await Page.setEmail(user.email);


   
  }
}

Smoke.ts

test("Smoke Test", async (t) => {
  console.log("Starting test");  
  await Login.createUser(
  "google.com","joe"
  );

An error appear : Expected 1 arguments, but got 2.

>Solution :

The method createUser is expecting an object with the following shape:
{
url: string,
email: string,
}

And you are passing a string as first parameter and another string as the second parameter.

you should be passing an abject like this:

createUser({ 
   url: 'google.com', 
   email: 'joe' 
})

BTW why are you using "interface" and not "type" here?
type is more common for defining object shapes and interface is often used to describe behaviours
