Test::Unit questions

[enroxorz]

I am a little new with Test::Unit and am coming from a PHPUnit
background.

1. How are test dependencies done with Test::Unit? I am looking to do
something similar to how PHPUnit does it: http://pastebin.com/yExugFYD
2. Can I call an individual test method from outside the Test::Unit
class?
3. Is there a setup_before and a teardown_after? http://pastebin.com/QtHbFjpp

Thank you very much for your help in advance.

Hello,

2. Can I call an individual test method from outside the Test::Unit
class?

Yes. Take a look on TestSuites.
Here a little example. It calls MyTest#test_3 in demo.rb.

gem 'test-unit'
require 'test/unit'
require 'test/unit/ui/console/testrunner'

require './demo'

#create a new empty TestSuite, giving it a name
my_tests = Test::Unit::TestSuite.new("My Special Tests")
my_tests << MyTest.new('test_3')

#run the suite
Test::Unit::UI::Console::TestRunner.run(my_tests)

3. Is there a setup_before and a teardown_after? http://pastebin.com/QtHbFjpp

Yes.

See attached example.
setup/teardown is done once for each test.
startup/shutdown is done once per TestCase.

gem 'test-unit', '>= 2.1.1' #startup
require 'test/unit'

class Test_setup < Test::Unit::TestCase
def setup
puts "Setup"
end

def teardown
puts "End"
end

def test_1()
puts "Testing setup 1"
assert_equal(2, 1+1)
end
def test_2()
puts "Testing setup 2"
assert_equal(2, 1+1)
end

end

class Test_startup < Test::Unit::TestCase
def self.startup
puts "startup"
end

def self.shutdown
puts "shutdown"
end

def test_1()
puts "Testing startup 1"
assert_equal(2, 1+1)
end
def test_2()
puts "Testing startup 2"
assert_equal(2, 1+1)
end
end
