Testing & Quality Assurance

In any high-scale CMS migration project (especially when moving from a tightly integrated platform like HubSpot to WordPress), testing & Quality Assurance isn’t just another stage of the migration process. It’s the stage that validates that your new system really works in the real world, not just in a development environment.

Said another way: Good QA closes the gap between theory and reality. It checks every piece: the frontend design, the backend working, and the content work as intended.

This stage confirms that your new WordPress CMS stack is truly ready to replace the old one, and unlock its promise to do more, better.

Functional testing

Functional testing ensures every feature, integration, and workflow you’ve rebuilt on WordPress works exactly as it did (or better than) in HubSpot.

What to cover:

• Test case templates: For each major feature or module, write clear test cases. Example: “Contact form submits data to CRM and shows success message.”
• User scenario testing: Test real-world visitor journeys. If a user downloads a gated asset, does the lead data reach your CRM? If someone switches languages, does the content switch seamlessly?
• Business process validation: Check workflows behind the scenes: Does content move through the editorial flow? Are marketing triggers live? Do APIs pass data in and out properly? Map these workflows in advance and confirm each one works end-to-end.

Build functional test cases alongside your migration plan. Don’t leave them to the end — they become your QA roadmap. At rtCamp, we prioritize a “shift-left” approach to QA and testing. We build functional test cases alongside the migration plan itself. These cases become your QA roadmap, not an afterthought.

User Acceptance Testing (UAT)

UAT puts your new WordPress site in the hands of the people who actually run it (editors, marketers, content owners) before it goes live.

Key steps for UAT:

• Stakeholder involvement: Identify who needs to sign off: marketing, design, legal, product owners, regional leads.
• Clear testing criteria: Define upfront what “ready to launch” looks like. Does the content render correctly? Are form submissions tracked? Are integrations firing?
• Feedback collection: Track feedback in a single system (sheets, tickets, or your project management solution) and prioritize fixes logically: some must be fixed pre-launch; others can go into your post-launch backlog.

Run UAT in short, structured sprints (a week or two max) so feedback doesn’t drag out your launch. Get clear approvals in writing as UAT isn’t finished until all key owners agree it’s ready!

Performance testing

It’s not enough for your new WordPress site to “look” right. It has to run right, too. That means speed, stability under load, and strong Core Web Vitals scores.

What to test:

• Speed testing: Use Lighthouse, WebPageTest, or similar tools to check load times for key pages. Flag large assets, render-blocking scripts, or unused code.
• Load testing: Simulate realistic traffic spikes, especially if you expect seasonal surges or campaign pushes. Tools like k6 or LoadImpact help you spot server-side bottlenecks before your real users do.
• Mobile performance: Validate how the site performs on 3G/4G and older devices. Many sites look fine on desktop but choke on slower connections.
• Core Web Vitals: Test for LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), and FID (First Input Delay). These signals directly affect your SEO and real user experience.

Run these tests in a robust staging environment, ideally identical to production. Tune performance before go-live, not after.

Wrapping it up…

In the end, a new CMS migration project isn’t judged by the plan on paper, it’s judged by how solidly it performs when real visitors arrive and real teams get to work. Thorough testing and quality assurance close the gap between a promising rebuild and a live site that actually delivers from the first click. 

When you invest in HubSpot to WordPress migration QA, you’re not just preventing technical problems, you’re securing the trust, reach, and results your business depends on.

For any HubSpot to WordPress migration, this final stage transforms a risky handover into a calm, confident launch. Get it right, and the migration isn’t just done… it’s truly ready.
