Testing Agent

The Testing Agent is LaunchPulse’s built-in quality layer. After LaunchPulse completes a task, the Testing Agent helps review the result, clean up the code, detect issues, and fix problems before you continue building. It is not a separate beta feature you need to turn on. It works inside the LaunchPulse build process to help keep your project stable as it grows.
Think of the Testing Agent as an automatic reviewer that checks each task after it is completed, so every change has a better chance of working before you move on to the next one.

​
What the Testing Agent does

Reviews completed tasks

After a build step finishes, the Testing Agent checks what changed and looks for obvious issues in the result.

Cleans up code

It helps remove messy, duplicated, or unnecessary code created during the build process.

Fixes detected issues

When LaunchPulse finds errors, broken states, or incomplete logic, the Testing Agent helps repair them.

Checks user flows

It helps verify that important flows still make sense after a new feature or change is added.

Reduces regressions

It helps catch cases where a new update accidentally breaks something that was already working.

Improves build quality

It supports cleaner, more reliable output as your app grows from a simple MVP into a larger product.

​
How it fits into the LaunchPulse workflow

The Testing Agent works in the background as part of the build cycle.
1

You request a task

You ask LaunchPulse to build, update, fix, or improve part of your app.
2

LaunchPulse completes the change

The platform updates the app, code, screens, flow, or product logic based on your request.
3

Testing Agent reviews the result

After the task is completed, the Testing Agent checks the work for issues, messy code, broken behavior, or incomplete changes.
4

Issues are cleaned or fixed

If problems are detected, LaunchPulse can clean up the code, repair issues, and make the result more stable.
5

You preview and continue

You review the app in preview, test the main flow, and continue with the next focused request.

​
When the Testing Agent helps most

The Testing Agent is especially useful after:
  • adding a new feature
  • changing an existing page or screen
  • updating navigation
  • connecting a flow between pages
  • adding authentication, payments, storage, or AI services
  • fixing a bug
  • preparing a web app for publishing
  • preparing a mobile app for iOS or Android publishing
  • making design or layout changes across multiple screens
The Testing Agent helps automatically, but you should still preview the app yourself. The best workflow is: build → automatic review → preview → focused follow-up prompt.

​
What it checks

AreaWhat the Testing Agent helps with
Code qualityCleans messy code, reduces duplication, and improves structure
Build errorsLooks for errors that prevent the app from running properly
UI issuesHelps catch broken layouts, missing states, or inconsistent screens
User flowsChecks whether important actions still make sense after changes
Feature logicLooks for incomplete or conflicting behavior
Regression riskHelps reduce cases where new changes break existing work
Launch readinessSupports final cleanup before publishing or app store preparation

​
Example: how it works after a task

Imagine you ask LaunchPulse: 
Add a booking flow to my fitness coach mobile app.

Users should be able to:
- choose a coach
- select a date and time
- confirm the session
- see a booking confirmation screen
After LaunchPulse builds the booking flow, the Testing Agent helps check the result. It may look for things like:
  • whether the new booking screens were added correctly
  • whether the navigation between screens works
  • whether the confirmation state exists
  • whether the app has obvious broken logic
  • whether the code needs cleanup after the change
  • whether the new flow accidentally affects another part of the app

​
How to prompt for stronger testing

Even though the Testing Agent is built in, you can still ask LaunchPulse to focus the review. Use prompts like: 
Review the changes from the last task and fix any issues you find.

Focus on:
- broken buttons
- missing states
- layout problems
- incomplete logic
- anything that could break the main user flow
Or: 
Test the booking flow from start to finish.

Check that a user can:
1. open the booking page
2. choose a date and time
3. confirm the booking
4. see a success state

Fix anything that prevents this flow from working.
Or: 
Clean up the code from the last feature.

Do not add new features.
Focus only on:
- removing duplication
- fixing errors
- improving structure
- keeping the same user experience

​
Best way to use the Testing Agent

Build one feature at a time

Smaller tasks are easier for LaunchPulse to review, test, and clean up properly.

Preview after major changes

Use the live preview to check the result like a real user before adding more features.

Ask for focused checks

If a flow matters, ask LaunchPulse to test that exact flow instead of asking for a generic review.

Fix before expanding

If something feels broken, fix it before asking LaunchPulse to add more functionality.

​
Testing by task type

Task typeGood testing prompt
New page“Check the new page for layout issues, broken links, and missing empty states.”
New feature“Test this feature end-to-end and fix anything that blocks the main flow.”
Design update“Review the page on desktop and mobile sizes and fix spacing or layout issues.”
Payment flow“Check the payment journey from pricing to confirmation and identify anything incomplete.”
Authentication“Test sign-up, login, logout, and protected page behavior.”
Mobile app flow“Check the mobile screens, navigation, tap targets, and success states.”
Pre-launch“Review the app for broken flows, obvious bugs, unfinished states, and launch blockers.”

​
What the Testing Agent does not replace

The Testing Agent improves quality, but it does not remove the need for human review. Before launching, you should still:
  • click through the live preview yourself
  • test the main user journey
  • check the app on desktop and mobile sizes
  • review important copy and messaging
  • confirm payments or subscriptions if included
  • check authentication if included
  • test mobile publishing flows if building a mobile app
  • ask real users or teammates to try the product
Automatic testing helps catch issues earlier, but no automated review can guarantee that every product decision, edge case, or user expectation is correct.

​
Common mistakes

MistakeBetter approach
Adding many features before testingBuild one feature, let it be reviewed, then preview it
Asking for vague testingAsk LaunchPulse to test a specific flow
Ignoring the previewClick through the app after major changes
Continuing after a broken taskFix the issue before adding more features
Asking for redesign and bug fixes togetherSeparate design polish from technical cleanup
Publishing without final reviewRun one final testing and cleanup pass before launch

​
Final pre-launch testing prompt

Use this before publishing a web app or preparing a mobile app for store release: 
Run a final testing and cleanup pass before launch.

Check:
- main user journey
- navigation
- broken buttons or links
- layout issues
- mobile responsiveness
- empty states
- authentication flow, if included
- payment or subscription flow, if included
- obvious bugs or unfinished screens

Fix clear issues and tell me what still needs manual review.
