rspec users - Jul 2011 - How can I make before/after all a method?

I would like to turn this:

describe TestClass do
before :all do
# set some config
end
after :all do
# restore some config
end
# do a bunch of tests to this
end

into

describe TestClass do
with_config_value(X)

# do a bunch of tests to this
end


Basically, I want to include before :all and after :all clauses into a test.
 However, I do not want this to apply toa ll tests.

Thanks in advance.

There a number of ways to do this, but if you really just want a method, then
just write one!

def with_config_value(foo)
  before(:all) do
    # stuff that can access foo
  end

  after(:all) do
    # more stuff that can use foo
  end
end

What you''re talking about is generally called a macro.

describe TestClass do
  def self.with_config_value(config)
    before :all do
      #set some config
    end

    #etc.
  end

  with_config_value(x) do
    # do a bunch of tests
  end
end

You can put the macro in a module and either use #extend to make it available in
a describe block, or use RSpec''s config.extend method to do that
automatically.

Does that help?

cheers,
Matt
