NAME
MooX::Cmd::Tester - MooX cli app commands tester
VERSION
version 1.000
SYNOPSIS
use MooX::Cmd::Tester;
use Test::More;
use MyFoo;
# basic tests as instance check, initialization check etc. is done there
my $rv = test_cmd( MyFoo => [ command(s) option(s) ] );
like( $rv->stdout, qr/operation successful/, "Command performed" );
like( $rv->stderr, qr/patient dead/, "Deal with expected command error" );
is_deeply( $rv->execute_rv, \@expected_return_values, "got what I deserve?" );
cmp_ok( $rv->exit_code, "==", 0, "Command successful" );DESCRIPTION
The test coverage of most CLI apps is somewhere between poor and wretched. With the same approach as App::Cmd::Tester comes MooX::Cmd::Tester to ease writing tests for CLI apps.
result_class
Builder for result class to use. Returns MooX::Cmd::Tester::Result by default.
test_cmd
my $rv = test_cmd( MyApp => \@argv );test_cmd invokes the app with given argv as if would be invoked from command line and captures the output, the return values and exit code.
Some minor tests are done to prove whether class matches, execute succeeds, command_name and command_chain are not totally scrambled.
It returns an object with following attributes/accessors:
- app - Name of package of App
- cmd - Name of executed (1st level) command
- stdout - Content of stdout
- stderr - Content of stderr
- output - Content of merged stdout and stderr
- error - the exception thrown by running the application (if any)
- execute_rv - return values from execute
- exit_code - 0 on success, $! when error occurred and $! available, -1 otherwise
test_cmd_ok
my $rv = test_cmd_ok( MyApp => \@argv );Runs test_cmd and expects it being successful - command_name must be in command_commands, etc.
Returns the same object test_cmd returns.
If an error occurred, no additional test is done (behavior as test_cmd).
ACKNOWLEDGEMENTS
MooX::Cmd::Tester is inspired by App::Cmd::Tester from Ricardo Signes. In fact, I reused the entire design and adopt it to the requirements of MooX::Cmd.
