Runner.startApp Method

Specifies a shell command that is executed before TestCafe runs tests. Use it to launch or deploy the tested application.

async startApp(command, initDelay) → this

After tests are finished, the application is automatically terminated.

The startApp function takes the following parameters:

Parameter	Type	Description Default
`command`	String	The shell command to be executed.
`initDelay` (optional)	Number	The amount of time (in milliseconds) allowed for the command to initialize the tested application.

TestCafe adds node_modules/.bin to PATH so that you can use binaries the locally installed dependencies provide without prefixes.
