Testing Plan

• Added unit tests

Pull request overview

This PR adds mParticle custom event logging to track every selectPlacements call for improved visibility and troubleshooting. Each time selectPlacements is invoked, a custom event of type "Other" (EventType 8) is logged with both the developer-passed attributes and the final merged attributes sent to Rokt.

Changes:

• Added a new logSelectPlacementsEvent function that logs custom events with both original and final attributes as JSON strings
• Modified selectPlacements to accept and track devPassedAttributes parameter
• Added comprehensive unit tests for the new logging functionality

The JSON.stringify calls on lines 294 and 295-296 could potentially throw an error if the attributes objects contain circular references, BigInt values, or other non-serializable data. While this is unlikely in typical usage, consider wrapping these calls in a try-catch block to prevent the logging from breaking the selectPlacements flow.

For example:

try {
    var eventAttributes = {
        devPassedAttributes: JSON.stringify(devPassedAttributes || {}),
        selectPlacementsAttributes: JSON.stringify(selectPlacementsAttributes || {})
    };
    window.mParticle.logEvent(EVENT_NAME_SELECT_PLACEMENTS, EVENT_TYPE_OTHER, eventAttributes);
} catch (error) {
    console.error('Error logging selectPlacements event:', error);
}

Suggested change

	var eventAttributes = {
	devPassedAttributes: JSON.stringify(devPassedAttributes || {}),
	selectPlacementsAttributes: JSON.stringify(
	selectPlacementsAttributes || {}
	),
	};
	window.mParticle.logEvent(
	EVENT_NAME_SELECT_PLACEMENTS,
	EVENT_TYPE_OTHER,
	eventAttributes
	);
	try {
	var eventAttributes = {
	devPassedAttributes: JSON.stringify(devPassedAttributes || {}),
	selectPlacementsAttributes: JSON.stringify(
	selectPlacementsAttributes || {}
	),
	};
	window.mParticle.logEvent(
	EVENT_NAME_SELECT_PLACEMENTS,
	EVENT_TYPE_OTHER,
	eventAttributes
	);
	} catch (error) {
	// Ensure logging issues do not break the selectPlacements flow
	console.error('Rokt Kit: Error logging selectPlacements event:', error);
	}
