TestCase human-readable name

[Dmitry V. Sabanin]

Hello!

I have a question about TestUnit. How can i set a human-readable name for my
TestCase? I see name argument for a new, but i don't know where class
instance is initialized. That would be nice if i could change name of TC from
setup().

I'm having trouble understanding what it is you want to change the name of.
In Test::Unit, what happens is that your TestCase class is initialized once
for each test that it contains. So if you have a TestCase like this:

class TC_Me < Test::Unit::TestCase
def test_me
end

def test_me_too
end
end

The framework will call the constructor of your TestCase once for each test:

TC_Me.new(:test_me)
TC_Me.new(:test_me_too)

Thus, the TestCase is 'named' once for each test that it contains.

I'm guessing that you're asking this question because you want to change the
output somehow... I might be able to help more if I can get a better feel
for what you're trying to accomplish.

HTH,

I want to do something similiar to, but for a test case:
def self.suite
suite = Test::Unit::TestSuite.new "Muravey News System Tests"
end
where output is:
Loaded suite Muravey News System Tests
Started
FFF
Finished in 0.008444 seconds.

Now output for testcases is:
1) Failure!!!
test_get_news(TC_MNS_View_News) [./tests/test_view.rb:28]:

I want TC_MNS_Views_News to be replaced with my own string, like in
TestSuite. If it's not possible i will live with that :)

This (or some variant) will work:

require 'test/unit'

class Test::Unit::TestCase
def name
"#@method_name(#{self.class.fixture_name})"
end
end

class TC_Me < Test::Unit::TestCase
def self.fixture_name
"It's all about ME!"
end

def test_me
flunk
end
end

Output:

Loaded suite t
Started
F
Finished in 0.02 seconds.

1) Failure!!!
test_me(It's all about ME!) [t.rb:15]:

1 tests, 1 assertions, 1 failures, 0 errors

I'm not sure I like this... the point of having the class name there is that
it makes it easier to figure out where in the world the failure occurred.
It's your code, though :-)

HTH,

Thanks a lot Nataniel!
Class name is good for searching where the failure is, but line number is more
usefull for me (class name don't give me much information, as for example
name of section where error happened do). But there is not much difference
here..
