ruby - How to run code before each test case in all tests in MiniTest? -

i need run code before each test in tests in minitest.

before did:

minitest::unit::testcase.add_setup_hook    ...code run before each test end 

after upgraded minitest version 4.7.2 shows following error:

undefined method `add_setup_hook' minitest::unit::testcase:class (nomethoderror) 

i using ruby mri 2.0.0p0.

solution

module myminitestplugin   def before_setup     super     # ...code run before test cases   end    def after_teardown     # ... code run after test cases     super   end end  class minitest::unit::testcase   include myminitestplugin end 

add_setup_hook removed in 4.6.0. https://github.com/seattlerb/minitest/commit/792a480ebeb32983b9150adae575b7c396e2ae63

use before_setup instead.
