For UI automation, I used Playwright with JavaScript to sign in via saved session state, create a project, upload the CSV, run the pipeline, wait up to two minutes for the run button, and assert success with a five minute timeout. For API testing, I used a black box approach by inspecting network calls and wrote four tests, two positive and two negative, including cases for missing auth and a fake project ID. For data validation, I compared input and output CSVs with row count, schema, casing, date formats, consistency, and whitespace checks, and I found a real bug where extra whitespace remained around the salary value in row 8. I did not request any action from viewers.
