Test::Expect - Automated driving and testing of terminal-based programs
# 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");
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.
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', );
The command may either be a string, or an arrayref of program and arguments; the latter for bypasses the shell.
command
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");
The expect_send subroutine sends a command to the program. You pass in the command and an optional comment.
expect_send("ping", "expect_send");
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");
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");
This returns the Expect object.
Closes the Expect handle.
