Writing Test Scripts in UX

How to Write a UX Test Script

Define Clear Objectives

Align each task with a specific research question.

Focus on validating a feature, identifying pain points, or understanding behaviors.

Use Realistic Scenarios

Frame tasks as relatable user goals.

Ground instructions in contextually accurate situations.

Keep Language Neutral

Avoid leading phrases.

Use simple, unambiguous language.

Prioritize Task Clarity

Break down complex workflows into digestible steps.

Use one instruction per task.

Maintain Consistent Structure

• Introduction 
• Warm-up Questions
• Scenario Setup
• Tasks
• Wrap-up Questions

Use consistent formatting for readability (bullet points, bolded instructions, scannable text).

Limit the Number of Tasks

Keep sessions to a minimum number of tasks for moderated tests.

For unmoderated tests, reduce task count to avoid fatigue.

Time and Difficulty Estimation

Estimate 3–5 minutes per task as a starting point.

Pilot test to verify that difficulty and pacing match your expectations.

Follow-up Questions in Moderated Testing

Prepare follow-ups like “What did you expect to happen?” or “What would you do next?”

Use Placeholder Data When Needed

Supply sample login info, dummy credit cards, or addresses.

Separate Core Tasks from Exploratory Tasks

Label required tasks clearly.

Isolate exploratory or optional tasks to avoid biasing behavior.

Control for Order Effects

Randomize task order when feasibe, especially in A/B testing.

Pre-Test Your Script

Run internal dry-runs with team members.

Adjust based on feedback before launch.

Write for the Test Environment

Tailor tasks to device type like mobile or desktop.

Include instructions on screen orientation, scrolling, or interactions as needed.

Include a Debrief Section

Allow space for reflection with open-ended questions like “What did you find most frustrating?”

How to Write Warm-up Questions for User Testing?

General Product Familiarity

“Can you tell me a bit about how you typically use something to solve the same problem?”

“How often do you use this product or service?”

“What’s the last app or website you used for this task?”

Current Tools and Habits

“What tools do you use to complete this task?”

“How do you usually go about solving this problem?”

“Can you walk me through a typical day when you're doing said activity?”

Experience Level

“How comfortable do you feel using technology on various devices?”

“Do you consider yourself more of a beginner, intermediate, or advanced user of this type of technology?”

Expectations and Preferences

“When using a tool like this, what’s most important to you?”

“What do you like or dislike about similar tools you’ve used in the past?”

Role and Context

“Can you tell me about your role and how it relates to the product?”

“What kinds of tasks do you do most often that relate to this?”

Best Practices for Writing UX Test Scripts

• Align tasks with research questions
• Avoid technical jargon or internal labels
• Keep instructions short and actionable
• Test your script internally before going live
• Include dummy data if login, payment, or input is required
