issue with upgrade to version 10.1.1

[AramSol]

After upgrading to version 10.1.1, we encountered an error. The same tests were working fine with versions earlier than 10.

The unit tests run fine in the browser, but the error only appears when trying to run them with grunt-contrib-qunit.

It looks like you're using QUnit 2.3.2 which is quite old. Consider updating that first!

https://github.com/qunitjs/qunit/blob/2.21.1/History.md

https://qunitjs.com/api/callbacks/QUnit.on/#the-error-event

The README says the minimum version is 2.2.0 which is incorrect indeed.

@Krinkle thanks for fast replay, we are using ui5 framework that provide only QUnit 2.3.2 and QUnit 1.18.0, it there any other way to fix this issue?

[Krinkle]

@AramSol You can use grunt-contrib-qunit 9.x for the time being. I also recommend filing an issue with UI5 to upgrade QUnit. There have been no breaking changes inside QUnit 2.x over the past 8 years. This should be a safe upgrade for them.

@AramSol See also UI5/openui5#3832, UI5/openui5#3204 (comment), UI5/openui5#1359, UI5/openui5#1105.

I believe if you modify your HTML file, you can use any QUnit version you like, instead of the default. For example, you can remove the loading of sap's qunit, and instead add:

<link rel="stylesheet" href="https://code.jquery.com/qunit/qunit-2.21.0.css">
<script src="https://code.jquery.com/qunit/qunit-2.21.0.js"></script>

Or, if you add "qunit": "^2.21.0" to package.json, you can reference ../node_modules/qunit/qunit/qunit.css and ../node_modules/qunit/qunit/qunit.js instead.
