Test::Unit running all tests with automated suite

[Brett Schuchert]

Am I missing something when using Test::Unit in Eclipse? I am used to
using JUnit and/or NUnit and being able to select a project and run all
of the tests. I don't see this feature and I suspect I'm just blind.

I've come up with the following "automated" suite script that seems to
get the job done. I had to do this in JUnit 5 years ago when the JUnit
eclipse 2.x plugin didn't support this:

require 'test/unit'
require 'find'

def allFiles
files = Array.new
Find.find('./') { |f|
if(f =~ /_test/)
f = f.sub(/\.\//, "").sub(/\.rb$/,"")
files.push(f)
end
}
files
end

allFiles().each {|f| require f}

A comment:
This is simple, I know. I only recursively find files that match
*_test.rb from the current directory then I require the files and
Test::Unit automatically generates the suite method for me. For now this
is adequate.

So two questions:

1. Is the necessary or what am I missing (I've just started using Ruby a
few days ago).
2. I assume someone can suggest to me ways to shorten this up. I'm all
ears.

Thanks!

There's an excellent article at the following URL on IBM's site
introducing the Ruby mode for Eclipse. Tthey run you through how to
set up Test::Unit run configurations. Hope this helps.

As far as eclipse goes, I cannot help you. Generically, there are
many ways to go about it.

+ Use testrb:

% testrb test/**/*_test.rb
[...]
Finished in 5.562656 seconds.

297 tests, 886 assertions, 0 failures, 0 errors

+ Here is a much more concise version of what you wrote:

(%w(test/unit) + Dir['**/*_test.rb']).each { |f| require f }

+ And then there is autotest:

% autotest
# and happily leave it running all day

+ And probably many more.

Andy,

Thanks, that is an excellent article for getting started and it's what I
started with. Unfortunately it only discusses running individual tests,
not suites of tests.

Ya, maybe I'm just an old Eclipse hack (I like using it). I even use a
VI plugin in eclipse.

+ Use testrb:

% testrb test/**/*_test.rb

Maybe instead of using Test::Unit I should be using other testing
frameworks. Not sure. When I started using Java years ago (and C++
before that) I did pretty much work at the command line.

+ Here is a much more concise version of what you wrote:

(%w(test/unit) + Dir['**/*_test.rb']).each { |f| require f }

Thanks, that's better. I need to update this to skip subversion meta
directories (.svn) but I'm sure I can figure that out.

+ And then there is autotest:

% autotest
# and happily leave it running all day

+ And probably many more.

So is there a direction in which the "ruby community" is going with
respect to unit testing and continuous integration?

2. I assume someone can suggest to me ways to shorten this up. I'm all

To answer both questions:

require 'test/unit'
require 'test/unit/collector/dir'

Test::Unit::Collector:ir.new.collect

By default this recursively collects and runs all test case classes in
the current directory in files that match the pattern test_*.rb. It is
very customizable though. For example to examine all .rb files for
tests:

dc = Test::Unit::Collector:ir.new
dc.pattern << /\b.*\.rb\Z/m
dc.collect

Someone really needs to properly document all the cool stuff included
with Test::Unit. That someone may be me eventually

Even better!

Thanks Ryan, I figured I was missing something obvious. Now if someone
would update the plugin to do this!
