have_files

Note: Fork with temporal compatibility fix, see: mosop/have_files#pulls

A Crystal Spec/spec2 matcher for testing if two file trees are identical.

Build Status

Requirements

  • Git (git diff) - is used for file comparison.

Installation

Add this to your application's shard.yml:

dependencies:
  have_files:
    github: amberframework/have_files

Usage

require "spec"
require "have_files/spec"

it "may work" do
  "/path/to/actual".should have_files "/path/to/expected"
end

If test fails, have_files generates a diff message like:

Failures:

  1) may work
     Failure/Error: nil.should have_files("/path/to/expected") do |dir|

        diff/test.txt | 2 +-
        1 file changed, 1 insertion(+), 1 deletion(-)

       diff --git a/diff/test.txt b/diff/test.txt
       index 8ab686e..415b41d 100644
       --- a/diff/test.txt
       +++ b/diff/test.txt
       @@ -1 +1 @@
       -Hello, World!
       +Hello, Worlb!

     # ./spec/hello_spec.cr:8

Preventing Namespace Pollution

To prevent pollution of top level namespace, you can directly create expectations.

require "spec"
require "have_files/spec/expectation"

it "may work" do
  "/path/to/actual".should HaveFiles::Spec::Expectation.new("/path/to/expected")
end

Or you can define the have_files method anywhere you like.

require "spec"
require "have_files/spec/dsl"

module Test
  extend HaveFiles::Spec::Dsl

  it "may work" do
    "/path/to/actual".should have_files "/path/to/expected"
  end
end

have_files "/path/to/expected" # => compile error

With spec2

You can also use have_files with spec2.

require "spec2"
require "have_files/spec2"

Spec2.describe "with spec2" do
  it "is expected to work" do
    expect("/path/to/actual") have_files "/path/to/expected"
  end
end

API

have_files

Parameters

  • expected_dir : A path to your expected file tree. (required)
  • base_dir : A base path of working directory. To compare file trees with git diff, have_files makes a working directory, that is temporary and uniquely named, under this path and copies all of target files into the working directory. (default: /tmp)
  • cleanup : Determines whether working directory will be deleted after test ends. (default: true)

Details

have_files treats an actual value as a path of directory whose actual files. Then have_files copies the directory into a working directory and compares it to an expected file tree.

Releases

    • (Breaking Change) nil can't be passed as an actual value any longer.
  • v0.2.0
