Module: RSpec::Core::Metadata

Defined in:
lib/rubypitaya/app-template/vendor/bundle/ruby/3.1.0/gems/rspec-core-3.12.0/lib/rspec/core/metadata.rb

Overview

Each ExampleGroup class and Example instance owns an instance of Metadata, which is Hash extended to support lazy evaluation of values associated with keys that may or may not be used by any example or group.

In addition to metadata that is used internally, this also stores user-supplied metadata, e.g.

RSpec.describe Something, :type => :ui do
  it "does something", :slow => true do
    # ...
  end
end

‘:type => :ui` is stored in the Metadata owned by the example group, and `:slow => true` is stored in the Metadata owned by the example. These can then be used to select which examples are run using the `–tag` option on the command line, or several methods on `Configuration` used to filter a run (e.g. `filter_run_including`, `filter_run_excluding`, etc).

Class Method Details

.ascend(metadata) ⇒ Object

Returns an enumerator that iteratively walks up the given metadata through all example group ancestors, yielding each metadata hash along the way.

def self.ascend(metadata)
  enum_for(:ascending, metadata)
end

.ascending(metadata) {|metadata| ... } ⇒ Object

Iteratively walks up from the given metadata through all example group ancestors, yielding each metadata hash along the way.

Yields:

  • (metadata)

    yield group_metadata
    break unless (group_metadata = group_metadata[:parent_example_group])
  end
end

.build_hash_from(args, warn_about_example_group_filtering = false) ⇒ Object

Used internally to build a hash from an args array. Symbols are converted into hash keys with a value of ‘true`. This is done to support simple tagging using a symbol, rather than needing to do `:symbol => true`.

.relative_path(line) ⇒ String

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns relative path to line.

Parameters:

  • line (String) —

    current code line

Returns:

  • (String) —

    relative path to line

.relative_path_regex ⇒ Object

Matches strings either at the beginning of the input or prefixed with a whitespace, containing the current path, either postfixed with the separator, or at the end of the string. Match groups are the character before and the character after the string if any.
