This is a low-level library used as the backbone for all Collection running & Request sending functionality, in the Postman App, and allied systems (Postman Monitoring, Newman)
If you are looking to execute collections, you should be using Newman, this is very low level.
npm run test: Runs lint, system, unit and integration tests of runtimenpm run test-integration-newman: This command runs tests of newman with the under-development variant of runtimenpm run test-coverage: This command runs postman-runtime tests and generate overall coveragenpm/memory-check.sh: This bash scripts performs first-level memory usage analysis, and plots a graph out of the resultsPostman Runtime supports a lot of options to customize its behavior for different environments and use-cases.
