Feature: basic structure (describe/it)
RSpec is a DSL for creating executable examples of how code is expected to
behave, organized in groups. It uses the words "describe" and "it" so we can
express concepts like a conversation:
"Describe an account when it is first opened."
"It has a balance of zero."
The `describe` method creates an example group. Within the block passed to
`describe` you can declare nested groups using the `describe` or `context`
methods, or you can declare examples using the `it` or `specify` methods.
Under the hood, an example group is a class in which the block passed to
`describe` or `context` is evaluated. The blocks passed to `it` are evaluated
in the context of an _instance_ of that class.
Scenario: one group, one example
Given a file named "sample_spec.rb" with:
"""
describe "something" do
it "does something" do
end
end
"""
When I run `rspec sample_spec.rb -fn`
Then the output should contain:
"""
something
does something
"""
Scenario: nested example groups (using context)
Given a file named "nested_example_groups_spec.rb" with:
"""
describe "something" do
context "in one context" do
it "does one thing" do
end
end
context "in another context" do
it "does another thing" do
end
end
end
"""
When I run `rspec nested_example_groups_spec.rb -fdoc`
Then the output should contain:
"""
something
in one context
does one thing
in another context
does another thing
