Running minitest produces no output
minitest setup do
I have a file
my_test.rb with the following contents:
require 'test/unit' class MyTest < Test::Unit::TestCase # Called before every test method runs. Can be used # to set up fixture information. def setup # Do nothing end # Called after every test method runs. Can be used to tear # down fixture information. def teardown # Do nothing end # Fake test def dummy_test print "Something!" fail end end
When I run
ruby my_test.rb, there is absolutely no output.
How can I run the unit tests in this file and see whether they are passing or failing?
There's nothing bad with your implementation and your actual code. But in order your
dummy_test can execute what's inside its definition, it should be called first; thing you're not doing, that's why when you run your file you don't get any output.
You can create an example test, and there call your dummy_test method:
... def test_something dummy_test end # Fake test def dummy_test print "Something!" fail end
Minitest fails to report back · Issue #20 · connorshea/vscode-ruby , When running all tests from ui, no output in console; When running A fix that makes it work is by modifying in minitest the run_one_method Many tests require that you examine the terminal output of your application. In this section, we’ll examine Minitest’s techniques for testing output. assert_silent. With many applications, methods, etc, the ideal situation is that no output at all is produced.
Test-unit will look for methods that start with "test" and use them as test methods. Your code has a method that ends with "test" but none that start with it, so it doesn’t see any tests to run.
Change the method name from
test_dummy and you should see the output you are expecting.
Quick Guide to Minitest command line arguments, Ruby comes with Minitest by default since version 1.9, which means Fortunately, Ruby also comes with a Rake::TestTask class that makes our lives easier. --no-plugins Bypass minitest plugin auto-loading (or set $MT_NO_PLUGINS). -d, --defer-output Output test failures and errors after the test run Dress Up Your Minitest Output Ruby folks are known to be a hyperactive lot, and it seems like few things in the Ruby world are as subject to change as the new hotness in testing. Over the years, I’ve used Test::Unit and RSpec at various times with a whole array of complementary libraries for test data and mocking and assertions and so on.
As said before you are not calling on your function and therefore nothing will happen since ruby does not automatically execute the first / last function.
An example would be to implement this code
... def main() print "Something!" end main()
And if you would like to call a function which calls the other functions you will do the same
def main() other_function1() other_function2() end main()
And the other_functions would be other functions you define and call within the main function.
Dress Up Your Minitest Output, Like a lot of people, I like that it's straightforward to use and takes no The output that Minitest produces by default is pretty basic, printing a dot If you are using minitest-reporters with ActiveSupport 3.x, make sure that you require ActiveSupport before invoking Minitest::Reporters.use!. Minitest-reporters fixes incompatibilities caused by monkey patches in ActiveSupport 3.x. ActiveSupport 4.x is unaffected. Rails Backtrace Filtering and Custom Backtrace Filtering

Test runner in Rails 5, Now failing tests point to line number and makes it easier to re run a failing test. runner inspired from RSpec, minitest-reporters, maxitest and others. while running the test then the output does not contain full stacktrace. If your generator engine is running but is producing no or low output, the circuit breaker is the first thing you should check. The breaker is a safety feature designed to automatically switch off if a surge of electricity or overload is detected.
Getting Started with Minitest - Semaphore Tutorial, This shows Minitest's power – it's just plain Ruby, no fancy syntax The output above shows the report from the tests that were run, It's a complete spec engine that works on top of Minitest::Unit, and seamlessly makes test When the residual magnetism is lost, the generator will produce no power at start-up. This residual magnetism can be lost naturally from not being used or from the load on your generator being connected when the generator is shut off. It can also happen from running a generator with no load for too long.
