Test::Expect(3p)

NAME
Test::Expect - Automated driving and testing of terminal-based programs

SYNOPSIS
  # in a t/*.t file:
  use Test::Expect;
  use Test::More tests => 13;
  expect_run(
    command => "perl testme.pl",
    prompt  => 'testme: ',
    quit    => 'quit',
  );
  expect("ping", "pong", "expect");
  expect_send("ping", "expect_send");
  expect_is("* Hi there, to testme", "expect_is");
  expect_like(qr/Hi there, to testme/, "expect_like");

DESCRIPTION
Test::Expect is a module for automated driving and testing of terminal-based programs. It is handy for testing interactive programs which have a prompt, and is based on the same concepts as the Tcl Expect tool. As in Expect::Simple, the Expect object is made available for tweaking.

Test::Expect is intended for use in a test script.

SUBROUTINES

  expect_run
The expect_run subroutine sets up Test::Expect. You must pass in the interactive program to run, what the prompt of the program is, and which command quits the program:

  expect_run(
    command => "perl testme.pl",
    prompt  => 'testme: ',
    quit    => 'quit',
  );

  expect
The expect subroutine is the catch all subroutine. You pass in the command, the expected output of the subroutine and an optional comment.

  expect("ping", "pong", "expect");

  expect_send
The expect_send subroutine sends a command to the program. You pass in the command and an optional comment.

  expect_send("ping", "expect_send");

  expect_is
The expect_is subroutine tests the output of the program like Test::More's is. It has an optional comment:

  expect_is("* Hi there, to testme", "expect_is");

  expect_like
The expect_like subroutine tests the output of the program like Test::More's like. It has an optional comment:

  expect_like(qr/Hi there, to testme/, "expect_like");

  expect_handle
This returns the Expect object.

expect_quit
Closes the Expect handle.
