Working porperly now by using TouchItem()
I tried the following. Here's a unit that I have called Parent
class ParentApp {
constructor(x) {
this.name = x;
}
}
module.exports = {ParentClass: ParentApp}
Here's another unit that I have called Child
var parent = require("Parent")
class Child extends parent.ParentClass {
constructor(y, z) {
super(y);
this.age = z;
}
}
function test() {
var myChild = new Child('Bill', 25);
Log.Message(myChild.age);
}
When I run the test function, I get written to my test log the value of 25. So, I'm not 100% certain what issue you're running into since it appears that our code is pretty much copies of each other.
Note that, in TestComplete, the require should always contain the unit name doing the import and that the unit must be in the same project. You mention that you have two different projects. The Parent.js unit needs to be in the same project as your Child.js unit.
See https://support.smartbear.com/testcomplete/docs/scripting/calling-routines/declared-in-another-unit/javascript.html for the specifics of using module.exports within TestComplete.
Hi Robert,
Thanks for the prompt response. I did help to reconsider what I was doing because the code I shared with you was OK. But I realised something - the issue was not due to these being in different projects - in fact I had shared the Parent.js into the project containing the Child.js. It was because of circular references. Though the TestComplete documentation says Javascript supports circular references, there is catch here:
My example question did not mention the full context - here's the code that I had issues with:
PARENT.JS
// In Parent.js - In Project 1, but shared into Project 2 using Add Existing Item...
var child = require("Child")
class ParentApp {
constructor(x) {
this.name = x;
}
}
function initializeGlobal()
{
var childObj = new child.ChildClass("Me", 3);
}
module.exports = {ParentClass: ParentApp}
CHILD.JS
// In Child.js - in Project 2 - also shared into Project 1
var parent = require("Parent")
class ChildApp extends parent.ParentClass {
constructor(y, z) {
super(y);
this.age = z;
}
}
function test() {
var myChild = new ChildApp('Bill', 25);
Log.Message(myChild.age);
}
module.exports = { ChildClass: ChildApp }
What was happening was that in Parent.js when the first .... var child = require("Child").... was called, the require tried to load Child.JS - and in this was trying to execute "class ChildApp extends parent.ParentClass" which threw an error. This was because parent.ParentClass wasn't loaded yet. If I removed the extends all was well.
So what I did was to refactor the code so that the function "initializeGlobal()" was in another common script that avoided the circular referencing. It seems circular referencing fails with extends.
SAMPLE WORKING CODE:
INIT.JS
// In Init.js, in Project 1
var parent = require("Parent")
var child = require("Child")
function initializeGlobal()
{
var childObj = new child.ChildClass("Me", 3);
}
PARENT.JS
// In Parent.js - In Project 1, but shared into Project 2 using Add Existing Item...
class ParentApp {
constructor(x) {
this.name = x;
}
}
module.exports = {ParentClass: ParentApp}
CHILD.JS
// In Child.js - in Project 2 - also shared into Project 1
var parent = require("Parent")
class ChildApp extends parent.ParentClass {
constructor(y, z) {
super(y);
this.age = z;
}
}
function test() {
var myChild = new ChildApp('Bill', 25);
Log.Message(myChild.age);
}
module.exports = { ChildClass: ChildApp }
So it's resolved now. Please try it and let me know if this works.
Sorry for getting back this late - the response is a tad too long if you see.
And yeah, I did not need the "import" keyword.
Thanks for the help. And thanks to Tanya for following-up.
Maybe I should accept my own answer as solution, I don't know.
Yeah, honestly, I'm not sure how that referencing would work outside of the TC environment anyways. Good catch, man. I marked your solution.
Thanks, Robert!
When you find some time if you can validate my solution, I would be quite happy. That's because you are much experienced at using TestComplete and that will give me some confidence.
Appreciate your time.
