NAME

Test::More::Behaviour - BDD module for Perl

INSTALL

cpan -i Test::More::Behaviour

DESCRIPTION

Test::More::Behaviour is a Behaviour-Driven Development module for Perl programmers. It is modeled after Rspec (http://rspec.info), the BDD tool for Ruby programmers.

Because Test::More::Behaviour uses Test::More as its 'base', you can treat every Test::More::Behaviour test as if it were Test::More!

SYNOPSIS

Basic structure

Test::More::Behaviour uses the words `describe` and `it` so we can express concepts of the application as we would in conversation:

"Describe a bank account."
"It transfers money between two accounts."

code:

describe 'Bank Account' => sub {
    it 'transfers money between two accounts' => sub {
        my $source = BankAccount->new(100);
        my $target = BankAccount->new(0);
        $source->transfer(50, $target);

        is($source->balance, 50);
        is($target->balance, 50);
    };
};

Then the output should be:

Bank Account
   transfers money between two accounts

The `describe` subroutine takes a description and a block. Inside the block you can declare examples using the `it` subroutine.

Nested groups

You can also declare nested groups using the `describe` or `context` subroutines.

describe 'Bank Account' => sub {
    context 'when opening without an initial amount' => sub {
        it 'has an initial balance of 0' => sub {
            ...
        };
    };

    context 'when opening with an initial amount of 100' => sub {
        it 'has an initial balance of 100' => sub {
            ...
        };
    };
};

QUICK REFERENCE

This project is built with the philosophy that 'Tests are the Documentation'. For a full set of features, please read through the test scenarios.

Some examples are listed with the source code (https://github.com/bostonaholic/test-more-behaviour) under `examples/`.

describe

Used to group a set of examples of a particular behaviour of the system that you wish you describe.

describe 'Bank Account' sub => {
    ...
};
it

An example to run.

describe 'Bank Account' => sub {
    it 'transfers money between two accounts' => sub {
        ...
    };
};
context

Used to further establish deeper relations for a set of examples. This is best used when several examples have similar interactions with the system but have differring expectations.

describe 'Bank Account' => sub {
    context 'when opening without an initial amount' => sub {
        it 'has an initial balance of 0' => sub {
            ...
        };
    };

    context 'when opening with an initial amount of 100' => sub {
        it 'has an initial balance of 100' => sub {
            ...
        };
    };
};
before_all
after_all

These subroutines will run before and after all the `it` examples.

sub before_all {
    ...
};
  
sub after_all {
    ...
};

describe 'Bank Account' => sub {
    it 'transfers money between two accounts' => sub {
        ...
    };
};
before_each
after_each

Used to define code which executes before and after each `it` example.

sub before_each {
    ...
};
  
sub after_each {
    ...
};

describe 'Bank Account' => sub {
    it 'transfers money between two accounts' => sub {
        ...
    };
};

BUGS AND LIMITATIONS

Currently, each `it` will not run as a Test::More::subtest. This is because the coloring was not working correctly because subtest needed the description before evaluating the block passed in. If you can fix this, please submit a github pull request and I will take a look.

If you do find any bugs, please send me an email or create a github issue (https://github.com/bostonaholic/test-more-behaviour/issues) or pull request with a failing test (and your fix if you're able to) and I will be more than happy to fix.
