Playwright Cookbook
Run a subset of tests
To run a subset of your test suite you can use the KNAPSACK_PRO_TEST_FILE_LIST_SOURCE_FILE environment variable:
Reporters
Use the blob reporter without specifying an outputDir or outputFile. Later, execute playwright --merge-reports to output any aggregated reports you need (e.g., json):
npx @knapsack-pro/playwright --reporter=blob,@knapsack-pro/playwright/reporters/batch
npx playwright merge-reports --reporter=list blob-report/
Knapsack Pro generates one blob file per batch of tests executed named as follows: blob-report/report-[HASH].zip (e.g., blob-report/report-24ad5ce.zip).
