You need not to define matrix_init_xxx method, but init with block:

In your test case:

def setup
  init(:logined){ login_as :dongbin}
end

then "login_as :dongbin" will be called when setup include "logined"

Reuse your test with after_filter

In your test case

  after_filter :render_form, :new, :edit

  def matrix_test_render_form
    assert_response :success
    assert assigns(:job)
    assert_form(assigns(:job), *@@job_default_attr.keys)
  end

  def matrix_test_new
    assert_template 'new'
  end

  def matrix_test_edit
    assert_template 'edit'
  end

Then matrix_test_render_form will be called after matrix_test_new or matrix_test_edit

  #assert_form
  assert_form(@user, :email, :password)

equals to

  assert_select("form[action=/users]") do
    assert_select("#user_email[name=?]", "user[email]")
    assert_select("#user_password[name=?]", "user[password]")
    assert_select("input[type=submit]")
  end

# Add a method named "create" for unit tests and functional tests
