Ruby Watir 在运行类之外找不到断言方法？

我有一个想要在许多测试用例中使用的类：

require 'rubygems'
require 'test/unit'
require 'watir'

class Tests < Test::Unit::TestCase
  def self.Run(browser)
    #  make sure Summary of Changes exists
    assert( browser.table(:class, "summary_table_class").exists? )
    # make sure Snapshot of Change Areas exists
    assert( browser.image(:xpath, "//div[@id='report_chart_div']/img").exists?  )
    # make sure Integrated Changes table exists
    assert( browser.table(:id, 'change_table_html').exists? )
  end
end

但是，当在我的一个测试用例中运行时：

require 'rubygems'
require 'test/unit'
require 'watir'
require 'configuration'
require 'Tests'

class TwoSCMCrossBranch < Test::Unit::TestCase
  def test_two_scm_cross_branch
    test_site = Constants.whatsInUrl
    puts " Step 1: go to the test site: " + test_site
    ie = Watir::IE.start(test_site)

    Tests.Run(ie)

  end
end

我收到错误：

NoMethodError: undefined method `assert' for Tests:Class
    C:/p4/dev/webToolKit/test/webapps/WhatsIn/ruby-tests/Tests.rb:8:in `Run'

缺少什么？谢谢！

I have a class that I want to use in many test cases:

require 'rubygems'
require 'test/unit'
require 'watir'

class Tests < Test::Unit::TestCase
  def self.Run(browser)
    #  make sure Summary of Changes exists
    assert( browser.table(:class, "summary_table_class").exists? )
    # make sure Snapshot of Change Areas exists
    assert( browser.image(:xpath, "//div[@id='report_chart_div']/img").exists?  )
    # make sure Integrated Changes table exists
    assert( browser.table(:id, 'change_table_html').exists? )
  end
end

However, when run in one of my test cases:

require 'rubygems'
require 'test/unit'
require 'watir'
require 'configuration'
require 'Tests'

class TwoSCMCrossBranch < Test::Unit::TestCase
  def test_two_scm_cross_branch
    test_site = Constants.whatsInUrl
    puts " Step 1: go to the test site: " + test_site
    ie = Watir::IE.start(test_site)

    Tests.Run(ie)

  end
end

I get the error:

NoMethodError: undefined method `assert' for Tests:Class
    C:/p4/dev/webToolKit/test/webapps/WhatsIn/ruby-tests/Tests.rb:8:in `Run'

What's missing? Thanks!

assert() 是 TestCase 上的实例方法，因此仅适用于测试实例。您在类方法中调用它，因此 Ruby 正在测试中寻找不存在的类方法。

更好的方法是将 Tests 设为模块，将 Run 方法设为实例方法：

module Tests
  def Run(browser)
    ...
  end
end

然后将 Tests 模块包含在测试类中：

class TwoSCMCrossBranch < Test::Unit::TestCase
  include Tests

  def test_two_scm_cross_branch
    test_site = Constants.whatsInUrl
    puts " Step 1: go to the test site: " + test_site
    ie = Watir::IE.start(test_site)

    Run(ie)
  end
end

这将使 Run 方法可用于测试，并且 Run() 将找到 assert()测试类中的方法。

assert() is an instance method on TestCase so would only be available to instances of Tests. You are calling it inside a class method so Ruby is looking for a class method in Tests which doesn't exist.

A better way to do this is to make Tests a module and the Run method an instance method:

module Tests
  def Run(browser)
    ...
  end
end

Then include the Tests module in your test class:

class TwoSCMCrossBranch < Test::Unit::TestCase
  include Tests

  def test_two_scm_cross_branch
    test_site = Constants.whatsInUrl
    puts " Step 1: go to the test site: " + test_site
    ie = Watir::IE.start(test_site)

    Run(ie)
  end
end

which will make the Run method available to the test and Run() will find the assert() method in the test class.
