TestRunner

This module exposes a wrapper testRunner around the ACT Rules Testcases for each of the rules in ACT Rules Repository, thereby allowing to execute a given evaluation function against the test case as a document context.

Usage of TestRunner

Code snippet, showing various ways to use the testRunner.

consttestRunner=require('testrunner')// testrunner refers to file entry file `src/index.js`// execute asyncconstresults=awaittestRunner(config);// or execute as a promise chaintestRunner(options).then(results=>{// explore results}).catch(error=>{// handle error})

Configuration Object for TestRunner

Members of the config object passed to the testRunner.

Name	Type	Default Value	Description
config.debug	Boolean	false	(Optional) Runs the testRunner in debug mode, which launches each test case page in a chromium (non-headless) mode
config.injectScripts	Array<String>[]	undefined	(Optional) A list of path or url of scripts to be injected into the puppeteer page context
config.globals	Object	undefined	(Mandatory) An object containing key-value pairs of variables or functions to be mounted as a global variable in the puppeteer page context for usage by the evaluate function
config.globals.rulesMap	Object	-	(Mandatory) An object containing key-value pairs of ruleId of each act-r rule mapped to a uniqueId of rule(s) to run against a chosen test tool
config.evaluate	Function	-`	(Mandatory) A function containing logic to be evaluated on the page context

An example configuration object is as below:

constconfig={debug: false,injectScripts: ['https://code.jquery.com/jquery-3.3.1.min.js'// can be relative paths to any scripts as well, (eg: `../../myscript.js`)],globals: {
rulesMap
// this can also contain functions to be made available on the page context// eg: myLogger: function(data) { console.log(data) }},evaluate: ()=>{// logic to be evaluated within the page context.}}

Rules Mapping

To help define a 1 to 1 or 1 to Many relationship between ACT Rules and the test tool, an object of key-value pairs must be defined with the key rulesMap in the config.globals.

A sample template to build mappings, showing each of the ACT Rules with their ids, can be seen here

An example mapping is as below:

construlesMap={'SC1-3-5-autocomplete-valid': ['autocomplete-valid']}

If no mapping is defined an error is thrown by the module.

NPM Scripts

There is no build mechanism for this module. The entry point is set to src/index.js

• npm run dev runs prettier to format, then lint, then test, followed by example usage.
• npm run lint runs eslint across all .js files.
• npm run test runs test and reports coverage both in terminal and coverage directory.
• npm run format runs prettier on the code base to format to standard code style.
