When developers challenge test results, don’t argue, just demonstrate. Testing isn’t about proving devs wrong. It’s about making the product right. Precision beats persuasion. -> Maintain bulletproof documentation such as test cases, logs, screenshots, and steps to reproduce. -> Use data, not opinions. -> If a bug is “not reproducible,” pair-test with the dev to replicate it. -> Explain risk, not just failure. How does this bug impact users?

I will show proof with logs, screenshots, videos and test data and will explain the issue's impact and reproducing bugs and linking them to requirements to help build trust and keep things clear for developers.

You can defend findings by presenting clear evidence—logs, screenshots, and reproducible steps. Use data to support claims and align results with requirements. Foster collaboration by addressing concerns openly, explaining methodologies, and inviting retesting if needed. A solution-focused approach builds trust.

Its the common phase where every testing team will face as part of daily job basis. Here are few steps can be followed and cross check on 1. Understand Developers Doubt and their point of validaity 2. Provide Concrete Evidence 3. Correlate with Requirements 4. Checking the Environment & Test Data 5. Reproduce the Issue 6. Cross Check on Automation & CI/CD Evidence

1. Show the Proof – Share test reports, logs, and steps to reproduce the issue. Let the data speak for itself. 2. Explain the Impact – Use real examples and metrics to show why the findings matter. Keep it clear and relevant. 3. Work Together – Invite developers to review and retest with you. A team approach builds trust and clarity.
