Passing the Level Two (G2) road test gives you full Class G driving privileges. The two-step licensing system takes at least 20 months to complete and includes two road tests. Graduated licensing lets you gain driving skills and experience gradually, in lower-risk environments. To help new drivers develop better, safer driving habits, Ontario introduced graduated licensing in 1994 for all drivers applying for their first car or motorcycle licence. In fact, Rails provides the following classes for you to inherit from:Įach of these classes include Minitest::Assertions, allowing us to use all of the basic assertions in our tests.Statistics show that new drivers of all ages are far more likely than experienced drivers to be involved in serious or fatal collisions. 2.6 A Brief Note About Test CasesĪll the basic assertions such as assert_equal defined in Minitest::Assertions are also available in the classes we use in our own test cases. You can also pass named routes such as assert_redirected_to root_path and Active Record objects such as assert_redirected_to see the usage of some of these assertions in the next chapter. ), message=nil)Īsserts that the response is a redirect to a URL matching the given options. AssertionĪssert_not_equal( expected, actual, )Įnsures that expected.equal?(actual) is true.Īssert_not_same( expected, actual, )Įnsures that expected.equal?(actual) is false.Įnsures that a string matches the regular expression.Įnsures that a string doesn't match the regular expression.Īssert_includes( collection, obj, )Īssert_not_includes( collection, obj, )Īssert_in_delta( expected, actual,, )Įnsures that the numbers expected and actual are within delta of each other.Īssert_not_in_delta( expected, actual,, )Įnsures that the numbers expected and actual are not within delta of each other.Īssert_in_epsilon ( expected, actual,, )Įnsures that the numbers expected and actual have a relative error less than epsilon.Īssert_not_in_epsilon ( expected, actual,, )Įnsures that the numbers expected and actual have a relative error not less than epsilon.Įnsures that the given block throws the symbol.Īssert_raises( exception1, exception2. Specify to make your test failure messages clearer. The parameter is an optional string message you can Here's an extract of the assertions you can use with They are the ones that actually perform the checks to ensure that things are going as planned. Assertions are the worker bees of testing. 2.4 Available Assertionsīy now you've caught a glimpse of some of the assertions that are available. Test "should report error" do # some_undefined_variable is not defined elsewhere in the test case assert_raises ( NameError ) do some_undefined_variable end end Copy In this case, we can modify our test environment by changing the options found in config/environments/test.rb. The application_system_test_case.rb holds the default configuration for your systemīy default, every Rails application has three environments: development, test, and production.Įach environment's configuration can be modified similarly. The test_helper.rb file holds the default configuration for your tests.
