In the context of a custom matcher, you can call helper methods that are available from the
current example's example group. This is used, for example, by rspec-rails in order to wrap
rails' built-in assertions (which depend on helper methods available in the test context).
Scenario: call method defined on example from matcher
Given a file named "example_spec.rb" with:
"""ruby
RSpec::Matchers.define :bar do
match do |_|
foo == "foo"
end
end
RSpec.describe "something" do
def foo
"foo"
end
it "does something" do
expect("foo").to bar
end
end
"""
When I run `rspec ./example_spec.rb`
Then the output should contain "1 example, 0 failures"
Scenario: call method _not_ defined on example from matcher
Given a file named "example_spec.rb" with:
"""ruby
RSpec::Matchers.define :bar do
match do |_|
foo == "foo"
end
end
RSpec.describe "something" do
it "does something" do
expect("foo").to bar
end
end
"""
When I run `rspec ./example_spec.rb`
Then the output should contain "1 example, 1 failure"
And the output should match /undefined.*method/
And the output should contain "RSpec::Matchers::DSL::Matcher"
And the output should not contain "ExampleGroup"
