Usage:
# First, remember to build opencv.js with tests enabled:
${colors.blueBright(`python ./platforms/js/build_js.py build_js --build_test`)}
# Install the tool locally (needed only once) and run it
${colors.blueBright(`cd build_js/bin`)}
${colors.blueBright(`npm install`)}
${colors.blueBright(`node run_puppeteer`)}
By default will run a headless browser silently printing a small report in the terminal.
But it could used to debug the tests in the browser, take screenshots, global tool or
targeting external servers exposing the tests.
TIP: you could install the tool globally (npm install --global build_js/bin) to execute it from any local folder.
# Options
* port?: number. Default 8080
* buildFolder?: string. Default __dirname (this folder)
* debug?: boolean. Default false
* noHeadless?: boolean. Default false
* serverPrefix?: string . Default http://localhost
* help?: boolean
* screenshot?: boolean . Make screenshot on failure by default. Use --no-screenshot to disable screenshots completely.
* noExit?: boolean default false. If true it will keep running the server - together with noHeadless you can debug in the browser.
* noTryCatch?: boolean will disable Qunit tryCatch - so exceptions are dump to stdout rather than in the browser.
* maxBlockDuration: QUnit timeout. If noExit is given then is infinity.
