The opening plays smoothly. Your preferred choice reaches the right scene. The project feels ready—until someone selects the other option and lands in an explanation that makes no sense.

Branching video testing checks both the mechanics and the meaning of an interactive experience: does each choice play the intended content, can viewers operate it, and does the ending fit the route they took? Treat it as a short release review, not a single watch-through.

List each decision, the options viewers see, the expected next clip, and the intended ending. Add a place for the actual result and any issue you find. A simple document is enough for a small project.

Hypothetical example: a creator makes a product demonstration with two options: “See a quick overview” and “Explore the setup.” The overview route should show the summary; the setup route should show the demonstration. Both later reach a shared invitation to learn more.

Test both routes from the start. Then check the join: does the shared invitation still make sense if the viewer never saw the setup? Reusing a clip can be sensible, but its words must not assume an earlier scene that only some viewers watched.

For larger projects, mark every connection you have checked and note which combinations remain unreviewed. Seeing every clip once does not establish that every route through those clips works.

Before clicking an option, read it as a new viewer would. What do you expect to happen? Then compare that expectation with the destination, its opening sentence, and the next available action.

• Replace vague labels such as “Continue” when the alternatives lead to different topics.
• Check for repeated introductions, missing context, sudden changes in tone, and endings that contradict earlier choices.
• Confirm that links and contact instructions still point to the intended next step.

Record issues precisely: the route, the choice, what you expected, and what happened. “Setup choice plays the overview clip” is easier to fix and retest than “the video is confusing.”

A route can be technically correct and still be difficult to understand. Ask someone from the intended audience to use the project while you observe. Tell them you are reviewing the experience, not assessing their ability.

The GOV.UK Service Manual describes moderated usability testing as watching participants attempt specific tasks. Its guidance recommends relevant, believable tasks and neutral instructions.

For the hypothetical demo, try: “You want to understand what would be involved in setting this up.” Avoid “Click Explore the setup.” Nielsen Norman Group's task-scenario guidance likewise recommends realistic activities that do not give away how to use the interface.

Notice hesitation, unexpected choices, and requests for clarification. Ask what the person expected, then revise the content or labels. A small qualitative review can reveal issues; it does not establish a universal success rate.

Test where the audience will encounter the project, not only in the authoring workflow. Check the supported browser and device combinations that matter to your audience. Confirm that choices remain readable and usable on a smaller screen and that the media loads under the intended delivery conditions.

Try the essential interactions without a mouse. W3C's explanation of WCAG's keyboard criterion describes keyboard-operable functionality. Check whether viewers can reach and activate choices, use relevant playback controls, and understand where focus is. Investigate any barrier instead of assuming the player handles it.

Also review captions, written alternatives, audio clarity, and important visual information. These checks are a starting point, not a complete accessibility audit or certification.

IVPLEX's interactive-video guide explains that viewer decisions determine the next video segment. Its getting-started walkthrough introduces video nodes, conditions, and the visual editor.

Use your route log to compare the intended flow with the experience you deliver. Fix blocked routes and misleading destinations before sharing. After changing a shared clip or connection, recheck the affected routes—not only the one where you first noticed the issue.

Keep a brief release note with the version reviewed, date, reviewer, issues fixed, and remaining limitations. This checklist does not imply that IVPLEX provides an automatic path-testing tool.

Is one successful play-through enough?

No. It confirms only the route taken. Check the alternatives and any shared scenes they reach.

Does every viewer need to test every route?

No. Keep technical route coverage separate from observing representative viewers. Assign coverage deliberately across the review.

Should I retest after a small edit?

Recheck what the edit can affect. A label change affects expectations; a shared ending can affect several routes.
