JScript Language Reference¶
Important
Starting from Rapise 8.0, the default JavaScript engine used is NodeJS v14.15.3 runtime. Starting from Rapise 8.1, the default JavaScript engine used is NodeJS v18.18.0 runtime.
In versions prior to 6.7, Rapise used Microsoft JScript with WScript as the only available JavaScript engine. This document provides a language reference for that older version.
If you have existing tests or testing frameworks that are not compatible with NodeJS, you have the option to switch back to using WScript.
You can set the desired engine in two locations:
-
In the Test Settings (choose from Default, Node, WScript). The Default option uses the engine defined in the Global Options.
-
In the Global Options (choose from Default, Node, WScript). The Default option means Node.
NodeJS Support Features and Limitations¶
Features¶
- NodeJS v14 contains most of latest features of JavaScript including EcmaScript2015 (ES6) and beyond. You may see more detailed list of features here.
- You may find the most complete and up to date language reference at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference.
- You may use most of available npm packages in your test scripts. You may include
node_modulesfolders in the root of your testing framework (i.e.%WORKDIR%\node_modules).
Limitations¶
-
NodeJS engine now runs in 32 bit mode. This is required to keep compatibility with
ActiveXObjectsupport that is an essential part of WScript but has to be emulated in NodeJS. -
Rapise has own copy of node.exe installed. So if you have npm modules installed globally and need to use them in your test, you have to install them locally into the framework.
Reference¶
The language reference covers EcmaScript v2 supported by default JScript Engine. It is missing majority of latest features, properties and methods. For example, there is no Array.join or String.trim.
