Feature: expect error
Expect a proc to change the state of some object.
Scenario: expect error
Given a file named "expect_error.rb" with:
"""
describe Object, "#non_existent_message" do
it "should raise" do
expect{Object.non_existent_message}.to raise_error(NameError)
end
end
#deliberate failure
describe Object, "#public_instance_methods" do
it "should raise" do
expect{Object.public_instance_methods}.to raise_error(NameError)
end
end
"""
When I run "spec expect_error.rb"
Then the stdout should include "2 examples, 1 failure"
Then the stdout should include "expected NameError but nothing was raised"
Scenario: expect no error
Given a file named "expect_no_error.rb" with:
"""
describe Object, "#public_instance_methods" do
it "should not raise" do
expect{Object.public_instance_methods}.to_not raise_error(NameError)
end
end
#deliberate failure
describe Object, "#non_existent_message" do
it "should not raise" do
expect{Object.non_existent_message}.to_not raise_error(NameError)
end
end
"""
When I run "spec expect_no_error.rb"
Then the stdout should include "2 examples, 1 failure"
Then the stdout should include "undefined method `non_existent_message'"
