From 00c881d0dabe77fd2401beb0d39c7386b50bb791 Mon Sep 17 00:00:00 2001 From: David Schmitt Date: Mon, 14 Sep 2015 18:26:25 +0100 Subject: (MODULES-2516) Adds an is_a() function The data type system is very hard to understand. Many people don't understand why type_of([1,2,3]) == Array will fail, but type_of([1,2,3]) <= Array passes. This does a simpler validation that doesn't rely on explicit data types. Instead, use $foo = [1,2,3] if $foo.is_a(Array) { notify { 'This is an array': } } This is based on code by Ben Ford . * Added acceptance tests * Added dispatch * Improved unit tests * Added docs to README --- spec/functions/is_a_spec.rb | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 spec/functions/is_a_spec.rb (limited to 'spec/functions/is_a_spec.rb') diff --git a/spec/functions/is_a_spec.rb b/spec/functions/is_a_spec.rb new file mode 100644 index 0000000..8dec13f --- /dev/null +++ b/spec/functions/is_a_spec.rb @@ -0,0 +1,25 @@ +require 'spec_helper' + +if ENV["FUTURE_PARSER"] == 'yes' + describe 'type_of' do + pending 'teach rspec-puppet to load future-only functions under 3.7.5' do + it { is_expected.not_to eq(nil) } + end + end +end + +if Puppet.version.to_f >= 4.0 + describe 'is_a' do + it { is_expected.not_to eq(nil) } + it { is_expected.to run.with_params().and_raise_error(ArgumentError) } + it { is_expected.to run.with_params('', '').and_raise_error(ArgumentError) } + + it 'succeeds when comparing a string and a string' do + is_expected.to run.with_params('hello world', String).and_return(true) + end + + it 'fails when comparing an integer and a string' do + is_expected.to run.with_params(5, String).and_return(false) + end + end +end -- cgit v1.2.3
