Waterfall testing model in Testing Fundamentals - Build an Automation Script

Verify Waterfall Testing Model Phases Execution

Preconditions (2)

Step 1: Review the requirements documentation

Step 2: Verify the design document is created based on requirements

Step 3: Check that the implementation (coding) is done according to design

Step 4: Confirm that the testing phase is executed after implementation

Step 5: Validate that the deployment happens only after testing is complete

Step 6: Ensure maintenance phase is planned after deployment

✅ Expected Result: Each phase of the Waterfall testing model is completed in sequence without overlap, and the output of one phase is the input for the next phase.

Automation Requirements - N/A - Manual process verification

Assertions Needed:

Verify phase completion order

Verify documentation artifacts exist for each phase

Verify no phase starts before the previous phase ends

Best Practices:

Use checklist to confirm phase completion

Maintain clear documentation for each phase

Communicate phase status with stakeholders

Automated Solution

The Waterfall testing model is a sequential process and is mostly verified through documentation and process checks rather than automation code. Automation is not applicable here because it is a methodology, not a software feature. The test involves confirming that each phase is completed before the next begins, which is done by reviewing documents and project status reports.

Therefore, no automation script is provided. Instead, testers use checklists and documentation reviews to ensure the Waterfall phases are followed correctly.

Common Mistakes - 3 Pitfalls

Trying to automate the Waterfall model phases as if it were a software feature

Skipping phase verification and assuming phases are completed

Overlapping phases in Waterfall model

Bonus Challenge

Create a checklist template to manually track the completion of each Waterfall testing model phase with three sample projects.
