The “Looks Good to Me” Trap: Why Broken Builds Reach the Client
Nothing looks worse than sending a staging site over to a client and having them spot obvious visual bugs in five minutes. When QA gets skipped or rushed, developers end up drowning in re-work and the relationship takes a hit. We should always find our own mistakes first. Here is the testing routine I use to vet features internally before sharing them with stakeholders.
What is the QA, Testing, and Acceptance Criteria Stage?
This step is simple: we test everything internally before the client sees it. We run through the original acceptance criteria, push for edge-case errors, and verify the work is dependable. It turns raw code into something secure, tested, and ready for review.
The Deliverables: QA Test Matrix & Staging Sign-Off
The primary outputs of this stage are a structured QA Test Matrix and a verified Staging Sign-Off Report confirming the build meets all baseline requirements before moving to the client.
This phase focuses on four critical testing pillars:
- Acceptance Criteria Verification: Testing every functional path explicitly defined in the SFS to confirm each pass/fail condition is met without deviation.
- Cross-Browser & Device Validation: Verifying responsive layouts, touch interactions, and rendering consistency across modern browsers (Chrome, Safari, Firefox, Edge) and mobile viewports.
- Edge Case & Error State Testing: Deliberately testing boundary conditions, network failures, empty database states, and invalid user inputs to ensure error handling is graceful and secure.
- Defect Logging & Triage: Documenting bugs with exact reproduction steps, console logs, and video captures directly on the project board, categorizing issues by severity (Blocker, Major, Minor) for rapid resolution.
Next Steps
Once internal QA passes and staging is verified against all acceptance criteria, the build is ready for formal client review.
We close out the development lifecycle with Part 7: Deployment, UAT, and Post-Launch Warranty to handle client sign-off, domain cutovers, and post-launch stability.
