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 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.
Expect, Expect::Simple.
