Start with journeys that carry risk
Identify actions involving money, customer data or changes that are difficult to reverse. For booking, test availability, reservation, confirmation and cancellation together. Agree on expected results first. Use realistic test data containing missing values and boundary cases without copying sensitive production records into an unsecured test environment.
Deliberately test failure
Disconnect during submission, retry an action and simulate an unavailable dependency. Check what the user sees and whether work can safely resume. Include double clicks and expired sessions. A success message should reflect confirmed completion; a failure should preserve enough information for the customer to take a useful next step.
Combine automation and human checks
Use unit tests for isolated rules, integration tests for connected components and end-to-end tests for important journeys. Add manual checks for clarity, keyboard access and device behaviour. Prioritise useful coverage over a percentage target: numerous tests of implementation details can still overlook a broken customer journey.
Make release and rollback deliberate
Record known issues and agree which ones block release. Verify monitoring, backups and rollback before deploying. After release, check critical journeys with approved test accounts without creating unintended transactions. Give each incident an owner and identify which resolved failures should become regression tests to prevent the same issue returning.
Example: test a booking as a customer and as an operator
Create a booking using an approved test account, then locate it in administration, change an allowed status and verify the customer-facing result. Repeat with an unavailable slot and an interrupted submission.
Record the starting conditions, expected outcome and actual result. A defect report should explain how to reproduce the failure and its business effect, rather than only attaching a screenshot with “it does not work.”
A release checklist that covers more than screens
- Critical journeys and permissions verified.
- Failure, retry and duplicate-action cases reviewed.
- Arabic direction, labels and small-screen layouts checked.
- Monitoring, backups and rollback ownership confirmed.
- Known issues recorded with severity and an owner.
Choose checks according to product risk. A payment system and a brochure site do not need identical testing plans, even when both are built with the same framework.
Turn production incidents into focused regression checks
After resolving an incident, identify the rule or integration behaviour that failed and add a targeted check where useful. Keep test data and environments reproducible so failures can be investigated.
Review flaky tests rather than repeatedly rerunning them until they pass. A reliable small set of meaningful checks gives better release evidence than a large suite whose results the team no longer trusts.
