Test/unit : params order in assert_equal

ruby-talk
1

Hi all.

I've found myself to always writing:

assert_equal variable_to_test, 'value expected'

And Test::Unit says to me:
'some wrong value' expected but was 'value expected'

when I'd want to see

'value expected' expected but was 'some wrong value'

Is it because English is not my native? I mean, all others think that order

assert equal <what I test>, <what I expect>

is natural?

BTW, "my" order seems more natural to mee also because long expressions:
assert_equal some/very*long.calculations(Of::My.value), 'blah'
vs.
assert_equal 'blah', some/very*long.calculations(Of::My.value)

Thanks,
Victor.

expected always comes first for all the assertions.

Wrong example :slight_smile: I meant the opposite:

[Some very long calculation of x]
assert_equal x, %w(one two three four five) #my way
vs.
[Some very long calculation of x]
assert_equal %w(one two three four five), x #common way

sorry :slight_smile:

assert_equal seems backwards to native english speakers, too. use rspec
instead.

  require 'spec' # gem install rspec
  # calculate x
  x.should.equal %w(one two three four five)

it actually works!
