Javascript Classes vs. //USEUNIT

[francisd84]

I was a little bit surprised when I tried to create an object from a class located in another file within the same project when this file is imported using //USEUNIT and got a reference error

//File A
class MyClass
{
   constructor(x)
   {
      this.x = x;
   }
   GetX()
   {
      return this.x
   }
}

//File B
//USEUNIT A

function test()
{
  var myObj = new MyClass(5)
  //Or
  var myObj = new A.MyClass(5)
  //Will throw "Reference Error: MyClass is not defined"
}

I read couple of posts in this forum and, the fact of using "module.exports" and "require" seems (in my opinion) to defeat the purpose of //USEUNIT that I currently use to import global variables and functions from other units which works very well and makes code clean.

But unfortunately, classes from other files aren't imported using //USEUNIT.

Is it a known limitation of the implementation of Javascript through TestComplete?  A limitation of the engine? A bug? A misunderstanding of my own?

Thanks to help me see a little bit clearer on that.

This may be what you are looking for.  See the Referencing Other Script Units section.  It discusses module.exports and USEUNIT.

Thanks Marsha_R

I already read this page and didn't found answers that I wanted.

BUT, I think I found a workaround that will limit the use of "require" in one file only.

So if //USEUNIT only imports global variables and functions, so why not put the "require" statement within it's own file and then use //USEUNIT to import it?

//File A

var AClasses = require("A");

class MyClass
{
   constructor(x)
   {
      this.x = x;
   }
   GetX()
   {
      return this.x
   }
}

module.exports.MyClass = MyClass;


//File B
//USEUNIT A

function test()
{
  var myObj = new AClasses.MyClass(5)
  //Works!
}

IMO, this is a more cleaner way if we want to use the class in multiple units, we just need to use //USEUNIT instead of declaring another variable in each file.

Hi,

Is there a way we can call functions from one project into another. 

Project1 - > Unit1 -> Function1 returns something

Can we use Function1 into Project 2. Both projects are in the same suite
