实例公有方法

assert_class_method(method, content, &block)

断言给定类方法在给定内容中存在。此方法不检测类方法内部 (class << self)，只检测以“self.”开头的类方法。当提供代码块时，它将生成该方法的内容。

assert_migration "db/migrate/create_products.rb" do |migration|
  assert_class_method :up, migration do |up|
    assert_match(/create_table/, up)
  end
end

# File railties/lib/rails/generators/testing/assertions.rb, line 88
def assert_class_method(method, content, &block)
  assert_instance_method "self.#{method}", content, &block
end

assert_directory(relative, *contents)

别名: assert_file

assert_field_default_value(attribute_type, value)

断言给定属性类型获得适当的默认值

assert_field_default_value :string, "MyString"

源代码: 显示 | 在 GitHub 上

# File railties/lib/rails/generators/testing/assertions.rb, line 117
def assert_field_default_value(attribute_type, value)
  if value.nil?
    assert_nil(create_generated_attribute(attribute_type).default)
  else
    assert_equal(value, create_generated_attribute(attribute_type).default)
  end
end

assert_field_type(attribute_type, field_type)

断言给定属性类型被正确地转换为字段类型

assert_field_type :date, :date_select

源代码: 显示 | 在 GitHub 上

# File railties/lib/rails/generators/testing/assertions.rb, line 110
def assert_field_type(attribute_type, field_type)
  assert_equal(field_type, create_generated_attribute(attribute_type).field_type)
end

assert_file(relative, *contents)

断言给定文件存在。您需要提供一个绝对路径或相对于配置目标的路径

assert_file "config/environment.rb"

您也可以提供额外的参数。如果参数是正则表达式，它将检查正则表达式是否匹配给定文件的内容。如果它是一个字符串，它将比较文件与给定字符串

assert_file "config/environment.rb", /initialize/

最后，当提供代码块时，它将生成文件内容

assert_file "app/controllers/products_controller.rb" do |controller|
  assert_instance_method :index, controller do |index|
    assert_match(/Product\.all/, index)
  end
end
也称为: assert_directory

源代码: 显示 | 在 GitHub 上

# File railties/lib/rails/generators/testing/assertions.rb, line 25
def assert_file(relative, *contents)
  absolute = File.expand_path(relative, destination_root)
  assert File.exist?(absolute), "Expected file #{relative.inspect} to exist, but does not"

  read = File.read(absolute) if block_given? || !contents.empty?
  assert_nothing_raised { yield read } if block_given?

  contents.each do |content|
    case content
    when String
      assert_equal content, read
    when Regexp
      assert_match content, read
    end
  end
end

assert_initializer(name, *contents, &block)

断言给定初始化器存在。您需要提供相对于“config/initializers/`目录的路径。

assert_initializer "mail_interceptors.rb"

您也可以提供额外的参数。如果参数是正则表达式，它将检查正则表达式是否匹配给定文件的内容。如果它是一个字符串，它将比较文件与给定字符串

assert_initializer "mail_interceptors.rb", /SandboxEmailInterceptor/

最后，当提供代码块时，它将生成文件内容

assert_initializer "mail_interceptors.rb" do |initializer|
  assert_match(/SandboxEmailInterceptor/, initializer)
end

源代码: 显示 | 在 GitHub 上

# File railties/lib/rails/generators/testing/assertions.rb, line 141
def assert_initializer(name, *contents, &block)
  assert_file("config/initializers/#{name}", *contents, &block)
end

assert_instance_method(method, content)

断言给定方法在给定内容中存在。当提供代码块时，它将生成该方法的内容。

assert_file "app/controllers/products_controller.rb" do |controller|
  assert_instance_method :index, controller do |index|
    assert_match(/Product\.all/, index)
  end
end
也称为: assert_method

源代码: 显示 | 在 GitHub 上

# File railties/lib/rails/generators/testing/assertions.rb, line 100
def assert_instance_method(method, content)
  assert content =~ /(\s+)def #{method}(\(.+\))?(.*?)\n\1end/m, "Expected to have method #{method}"
  assert_nothing_raised { yield $3.strip } if block_given?
end

assert_method(method, content)

别名: assert_instance_method

assert_migration(relative, *contents, &block)

断言给定迁移存在。您需要提供一个绝对路径或相对于配置目标的路径

assert_migration "db/migrate/create_products.rb"

此方法操作给定路径并尝试找到任何与迁移名称匹配的迁移。例如，上面的调用将转换为

assert_file "db/migrate/003_create_products.rb"

因此，assert_migration 接受与 assert_file 相同的参数。

# File railties/lib/rails/generators/testing/assertions.rb, line 64
def assert_migration(relative, *contents, &block)
  file_name = migration_file_name(relative)
  assert file_name, "Expected migration #{relative} to exist, but was not found"
  assert_file file_name, *contents, &block
end

assert_no_directory(relative)

别名: assert_no_file

assert_no_file(relative)

断言给定文件不存在。您需要提供一个绝对路径或相对于配置目标的路径

assert_no_file "config/random.rb"
也称为: assert_no_directory

源代码: 显示 | 在 GitHub 上

# File railties/lib/rails/generators/testing/assertions.rb, line 47
def assert_no_file(relative)
  absolute = File.expand_path(relative, destination_root)
  assert !File.exist?(absolute), "Expected file #{relative.inspect} to not exist, but does"
end

assert_no_migration(relative)

断言给定迁移不存在。您需要提供一个绝对路径或相对于配置目标的路径

assert_no_migration "db/migrate/create_products.rb"

源代码: 显示 | 在 GitHub 上

# File railties/lib/rails/generators/testing/assertions.rb, line 74
def assert_no_migration(relative)
  file_name = migration_file_name(relative)
  assert_nil file_name, "Expected migration #{relative} to not exist, but found #{file_name}"
end
