Feature: Global namespace DSL
RSpec has a few top-level constructs that allow you to begin describing
behaviour:
* `RSpec.describe`: Define a named context for a group of examples.
* `RSpec.shared_examples`: Define a set of shared examples that can later be
included in an example group.
* `RSpec.shared_context`: define some common context (using `before`, `let`,
helper methods, etc) that can later be included in an example group.
Historically, these constructs have been available directly off of the main
object, so that you could use these at the start of a file without the
`RSpec.` prefix. They have also been available off of any class or module so
that you can scope your examples within a particular constant namespace.
RSpec 3 now provides an option to disable this global monkey patching:
```ruby
config.expose_dsl_globally = false
```
For backwards compatibility it defaults to `true`.
@allow-should-syntax
Scenario: By default RSpec allows the DSL to be used globally
Given a file named "spec/example_spec.rb" with:
"""ruby
describe "specs here" do
it "passes" do
end
end
"""
When I run `rspec`
Then the output should contain "1 example, 0 failures"
@allow-should-syntax
Scenario: By default rspec/autorun allows the DSL to be used globally
Given a file named "spec/example_spec.rb" with:
"""ruby
require 'rspec/autorun'
describe "specs here" do
it "passes" do
end
end
"""
When I run `ruby spec/example_spec.rb`
Then the output should contain "1 example, 0 failures"
Scenario: When exposing globally is disabled the top level DSL no longer works
Given a file named "spec/example_spec.rb" with:
"""ruby
RSpec.configure { |c| c.expose_dsl_globally = false }
describe "specs here" do
it "passes" do
end
end
"""
When I run `rspec`
Then the output should contain "undefined method `describe'"
Scenario: Regardless of setting
Given a file named "spec/example_spec.rb" with:
"""ruby
RSpec.configure { |c| c.expose_dsl_globally = true }
RSpec.describe "specs here" do
it "passes" do
end
end
"""
When I run `rspec`
Then the output should contain "1 example, 0 failures"
