Executing perl script from perl scripts

palette has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I have a number of perl scripts that execute from the crontab.
I want to write a test script that executes the perl files.
After executing each perl files I have to validate the database. So I have to add the test case for those validation.
Now I have to execute the next perl script in the same test script and validate that as well.
So it's sequential execution of some process scripts that I have to validate. But after each process script I will be doing some validation.
How can I do this in perl.
Does 'require' works fine for this.

example 1.pl
print "1";

2.pl
print "2";

test.t
require "1.pl"
ok("1","test 1");
require "2.pl";
ok("2","test 2");
Pls note I want require 1.pl to execute, complete the validation and then the require 2.pl should execute.

In a test file you should call the scripts in the same what that cron does, which is through a system call or the shell. You can do that in perl like this: `system($^X, '1.pl'); # and check for system's return value! ok(1, 'Test 1'); system($^X, '2.pl'); ok(2, 'Test 1');` [download] If you want to process the script output, use `my $res = qx($^X 1.pl); chomp $res; is($res, 1, '1.pl worked'); $res = qx($^X 2.pl); chomp $res; is($res, 2, '2.pl worked');` [download] (`$^X` is the path of the current perl interepreter)	[reply] [d/l] [select]

Getting an error on executing 1.pl should throw error telling that 1.pl is errored. 1.pl might not return a value '1'. What can be done in that case.	[reply]

So what happened when you tried that? Aside from the nit that I'd say you probably want to use do not require, your sample code (though unfortunately berefit of <code></code> tags) should do what you described. The cake is a lie. The cake is a lie. The cake is a lie.	[reply]

I'm not quite certain I understand the request, but if what you need is how to launch one process from another, take a look at How to avoid to launch a unix shell script in a perl script.	[reply]

Good idea to start with a simple test, but these tests are too simple. `ok("1","test 1");` tests whether `"1"` is a true value. If you ever find this test failing, please let me know.	[reply] [d/l] [select]
