NoMethodError: undefined method `assert_true'

NoMethodError: undefined method `assert_true'

Am getting above error while running tests using test-unit in ruby. test-unit gem and rake versions are below,

test-unit (2.5.5)
rake (10.1.0)

Sample test file:-

require 'test/unit'

class Sample < Test::Unit::TestCase

  def setup
    # code block
  end

  def test_sample
    assert_true("test"=="test")
  end

  def teardown
    # code block
  end

end

How to solve this ?

I solved the problem by using following way. No need to change assert statements.

require 'rubygems'
gem 'test-unit'
require 'test/unit'

class Sample < Test::Unit::TestCase

  def setup
    # code block
  end

  def test_sample
    assert_true("test"=="test")
  end

  def teardown
    # code block
  end

end

Since 1.9.2, test/unit is a wrapper around minitest, implemented directly in the ruby source code. The assert_true method does not exist in the new implementation, just use assert instead, as Simon Brahan already suggested. So the gem source you were looking at is no longer in use. The now relevant documentation is here.

assert_true does not appear to be in the list of available assertions for test-unit. Try using assert. Reference: http://ruby-doc.org/stdlib-2.0.0/libdoc/test/unit/rdoc/Test/Unit/Assertions.html
