Payload Driven Framework Creation

Building the Framework

• Define a standard payload format (e.g., JSON files or Excel sheets) for each API endpoint's test data.
• Build a "payload factory" component that reads and assembles payloads dynamically for each test.
• Create reusable utility methods to send requests and validate responses consistently.
• Wire the payload source into TestNG's @DataProvider so each data row runs as a separate test iteration.

Why This Approach Scales Well

Once built, adding a new test scenario often just means adding a new row of data or a new JSON payload file — no new code required.
