Pass Arguments To Test Command

[swensorm]

Requesting this as a feature to send arguments to the test command, without relying on npm or yarn directly. I came across this developing a bash script to run our UI regression tests within a Docker container using Storybook Storyshots and wanting to pass additional arguments, such as --updateSnapshot to the test command. The bash script sets up the container and runs a couple commands within it lastly being running the start-server-and-test command using npx.

• version: 1.11.0
• platforms: Mac OS, Docker image browserless/chrome:1.29.1-chrome-stable
• expected behavior: Runs test command passing arguments
• actual behavior: "Command not found"

Attempts at passing the arguments:

• npx start-server-and-test storybook http://localhost:9009 test:ui --updateSnapshot
  • Result: expected <NPM script name that starts with server> <url or port> <NPM script name that runs tests>
• npx start-server-and-test storybook http://localhost:9009 'test:ui --updateSnapshot'
  • Result: /bin/sh: test:ui: command not found
• npx start-server-and-test storybook http://localhost:9009 'test:ui -- --updateSnapshot'
  • Result: /bin/sh: test:ui: command not found

Working solution in bash script:

#!/bin/bash
npx start-server-and-test storybook http://localhost:9009 "npm run test:ui -- $@"

Desired solution:

#!/bin/bash
npx start-server-and-test storybook http://localhost:9009 "test:ui -- $@"
# or
npx start-server-and-test storybook http://localhost:9009 test:ui $@

For what its worth, this is a solution that works for my use case in executing npm scripts with and without start-server-and-test

Pass arguments to npm script using start-server-and-test ARGS="--spec cypress/integration/login.spec.js --browser chrome" npm run test:open:local:dev

Pass arguments to npm script not using start-server-and-test run test:live:dev -- --spec cypress/integration/login.spec.js --browser chrome
