How to Run All Tests With Minitest

How to run all tests with minitest?

Here's a link to Rake::TestTask.

There is an example in the page to get you started.

I'll post another one that I'm using right now for a gem:

require 'rake/testtask'

Rake::TestTask.new do |t|
  t.pattern = "spec/*_spec.rb"
end

As you can see, I assume that my files are all in /lib and that my specs are in /spec and are named whatever_spec.rb

Hope it helps.

How to run MiniTest::Unit tests in ordered sequence?

You can use i_suck_and_my_tests_are_order_dependent!() class method.

class MyTest < MiniTest::Unit::TestCase
  i_suck_and_my_tests_are_order_dependent!   # <----

  def test_1
    p 1
  end

  def test_2
    p 2
  end
end

But as the name suggest, it's not a good idea to make the tests to be dependant on orders.

Is it possible to run a single test in MiniTest?

I'm looking for similar functionality to rspec path/to/file.rb -l 25

With Nick Quaranto's "m" gem, you can say:

m spec/my_spec.rb:25

How do I run a single test file in minitest?

bin/rails test test/controllers/issues_controller_test.rb

Rails: How to prepare test-DBs for parallelized tests with Minitest

Thanks to edariedl's hint I was able set up the parallelised testing. I had to grant global permissions to my dev-sql user. This is different from my usual setting, where I grant permissions only to the dev-database.

After granting global privileges to my dev-sql user:

mysql > GRANT ALL PRIVILEGES ON *.* TO user@localhost;
mysql > FLUSH PRIVILEGES;

Minitest does the rest and forks the testing. It creates n Databases, where n is the amount of cpu-cores of your system.

In my case this kind of parallelisation appears to be more solid and faster than threaded testing.

I want to call def setup method before all tests in minitest ruby

You can use minitest-hooks gem with before_all something like:

require "minitest/autorun"
require 'minitest/hooks/test'

class TestLogin < MiniTest::Test
  include Minitest::Hooks

  def before_all
    puts "setup .."
  end

  def test_case1
    puts "testcase1"
  end

  def test_case2
    puts "testcase2"
  end
end

Now when you run the test you should see something like:

Run options: --seed 58346

# Running:

setup ..
testcase1
.testcase2
.

Finished in 0.001259s, 1588.7504 runs/s, 0.0000 assertions/s.

2 runs, 0 assertions, 0 failures, 0 errors, 0 skips
