// This small program is a proxy for the "jest" program defined by the Jest package. The proxy is
// necessary because Jest is not a dependency of the Expo package. Some package managers (e.g., npm)
// don't hoist binaries provided by nested dependencies, so to consistently define a program named
// "jest" we use this proxy script.
//
// We forward all arguments and stdio streams to the real "jest" program and exit with the same
// signal or status code.
//
// If you need to run Jest with the JS debugger enabled, run Jest directly. It is usually under
// node_modules/jest/bin/jest.js.
