02

Plan Test Scenarios

Identify testing scope, risk areas, critical user journeys, and target environments.

Prioritize scenarios based on business impact and risk assessment.

03

Design Test Cases

Create detailed test cases applying Equivalence Partitioning and Boundary Value Analysis.

Include clear pre-conditions, steps, input data, and expected outcomes.

04

Execute & Report

Run manual tests, uncover defects, and document comprehensive bug reports with reproduction steps.

Provide screenshots, logs, severity, and priority for developer clarity.

05

Verify & Improve
