Defined in:
lib/rspec/core/example_group.rb

Overview

ExampleGroup and Example are the main structural elements of rspec-core. Consider this example:

describe Thing do
  it "does something" do
  end
end

The object returned by describe Thing is a subclass of ExampleGroup. The object returned by it "does something" is an instance of Example, which serves as a wrapper for an instance of the ExampleGroup in which it is declared.

Example group bodies (e.g. describe or context blocks) are evaluated in the context of a new subclass of ExampleGroup. Individual examples are evaluated in the context of an instance of the specific ExampleGroup subclass to which they belong.

Besides the class methods defined here, there are other interesting macros defined in Hooks, MemoizedHelpers::ClassMethods and SharedExampleGroup. There are additional instance methods available to your examples defined in MemoizedHelpers and Pending.

end

+ (void) context + (void) context(&example_group_definition) + (void) context(doc_string, *metadata_keys, metadata = {}, &example_implementation)

An alias of example_group. Generally used when grouping examples contextually (e.g. "with xyz", "when xyz" or "if xyz"). Generates a subclass of this example group which inherits everything except the examples themselves.

Examples:


RSpec.describe "something" do # << This describe method is defined in
                              # << RSpec::Core::DSL, included in the
                              # << global namespace (optional)
  before do
    do_something_before
  end
  let(:thing) { Thing.new }
  context "attribute (of something)" do
    # examples in the group get the before hook
    # declared above, and can access `thing`
  end
end

Overloads:

  • + (void) context(&example_group_definition)

    Parameters:

    • example_group_definition (Block) —

      The definition of the example group.

  • + (void) context(doc_string, *metadata_keys, metadata = {}, &example_implementation)

    Parameters:

    • doc_string (String) —
