Phase 7: Quality Assurance and Testing

The quality assurance and testing phase is your last checkpoint before going live. Any issue that gets caught now can be a quick fix, but if you catch it post-launch, it won’t be a good experience for real visitors.

Content Testing

Check text, images, and heading structure across the site against your Phase 1 content inventory. That inventory shows exactly how many pages should exist and what each should contain. If something doesn’t match, that’s your first sign it didn’t migrate correctly.

Functional Testing

Test navigation, custom modules, search, and any interactive tools from Phase 5 – just the way a real visitor would use them. Edge cases and unusual inputs are where problems tend to surface.

Form Testing

For every form on your website, submit valid data and confirm it actually reaches your CRM and inbox. Then submit invalid data and check that validation and error messages work correctly.

A form that submits without an error isn’t proof it works. Verify the data lands where it should.

Responsive, Mobile, and Browser Testing

Test on real mobile devices (iOS and Android), tablets, and major desktop browsers (Chrome, Safari, Firefox, Edge). Pull your actual visitor data from Google Analytics on your new site. That way you’re testing what matters most to your audience, not just testing at random.

Performance Testing

Compare your new WordPress site against the Core Web Vitals baseline from Phase 1, using Google PageSpeed Insights or Search Console.

Check loading speed, interactivity, and visual stability. If the new site is slower, fix it before launch. This affects both rankings and how visitors experience your site.

Security Testing

Make sure SSL is installed correctly, WordPress core, theme, and plugins are updated, and a security plugin (Wordfence or Sucuri) is active.

Also check that user permissions follow least-privilege access, meaning people only get the access they actually need. Bring in your IT security team now, not after launch.

Stakeholder Review and User Acceptance Testing (UAT)

This is where you involve stakeholders for a final review of the site against the business requirements. Give them a clear checklist, set a feedback deadline, and log every issue as launch-blocking or post-launch.

What You Should Have When This Phase Is Done

By the end of Phase 7, you should have:

• Content verified against your original inventory
• Functional features and forms tested end-to-end
• Cross-device and cross-browser compatibility confirmed
• Performance benchmarked against your Core Web Vitals baseline
• Security review completed
• Documented stakeholder sign-off

With testing complete and sign-off secured, you’re ready for the moment this guide has been building toward: the actual launch and the careful process of replatforming over from Sitecore to WordPress without disrupting your business.
