@node-cli-toolkit/send-inputs-to-cli v0.4.2

@node-cli-toolkit/send-inputs-to-cli

This is a generic utility that should be able to send inputs to any CLI/process executed by child_process.exec. It's meant to be used in the context of Jest as it exports mock functions that fire when there's data on stdout or stderr. It is also mean to be used in conjunction with @node-cli-toolkit/test-cli

Supported Features:

• Send inputs to a CLI
• Set different timeout for inputs
• Set a default timeoutBetweenInputs

To see examples of each please see tests under __tests__

Usage

Basic usage

const { output, error, code } = await testSendInputToCLI({
  bashCommand: "ts-node ./mockCLIs/standard.ts",
  inputs: [
    // Check "Option 1"
    SPACE,

    // Move to "Option 2"
    DOWN,

    // Move to "Option 3"
    DOWN,

    // Check "Option 3"
    SPACE,

    // Next Question
    ENTER,

    // Type answer to "What's your name"
    "Anatoliy Zaslavskiy",

    // Submit answer to question
    ENTER
  ]
});

expect(error.mock.calls.length).toBe(0);

expect(code).toBe(0);

expect(output).toBeCalledWith(
  expect.stringMatching(/Which option do you want to choose\?/)
);

expect(output).toBeCalledWith(expect.stringMatching(/◯ Option 1/));

expect(output).toBeCalledWith(expect.stringMatching(/◯ Option 3/));

expect(output).toBeCalledWith(expect.stringMatching(/Option 1 Chosen/));

expect(output).not.toBeCalledWith(expect.stringMatching(/Option 2 Chosen/));

expect(output).toBeCalledWith(expect.stringMatching(/Option 3 Chosen/));

expect(output).toBeCalledWith(expect.stringMatching(/What's your full name\?/));

expect(output).toBeCalledWith(
  expect.stringMatching(/Your name is "Anatoliy Zaslavskiy"/)
);
