Public Class Methods

after_tests() click to toggle source

A simple hook allowing you to run a block of code after the tests are done. Eg:

MiniTest::Unit.after_tests { p $debugging_info }
# File lib/minitest/unit.rb, line 670
def self.after_tests
  at_exit { at_exit { yield } }
end
autorun() click to toggle source

Registers MiniTest::Unit to run tests at process exit

# File lib/minitest/unit.rb, line 677
def self.autorun
  at_exit {
    next if $! # don't run if there was an exception

    # the order here is important. The at_exit handler must be
    # installed before anyone else gets a chance to install their
    # own, that way we can be assured that our exit will be last
    # to run (at_exit stacks).
    exit_code = nil

    at_exit { exit false if exit_code && exit_code != 0 }

    exit_code = MiniTest::Unit.new.run ARGV
  } unless @@installed_at_exit
  @@installed_at_exit = true
end
out() click to toggle source

Returns the stream to use for output.

DEPRECATED: use ::output instead.

# File lib/minitest/unit.rb, line 706
def self.out
  warn "::out deprecated, use ::output instead." if $VERBOSE
  output
end
output() click to toggle source

Returns the stream to use for output.

# File lib/minitest/unit.rb, line 697
def self.output
  @@out
end
output=(stream) click to toggle source

Sets MiniTest::Unit to write output to stream. $stdout is the default output

# File lib/minitest/unit.rb, line 715
def self.output= stream
  @@out = stream
end
plugins() click to toggle source

Return all plugins’ run methods (methods that start with “run_”).

# File lib/minitest/unit.rb, line 739
def self.plugins
  @@plugins ||= (["run_tests"] +
                 public_instance_methods(false).
                 grep(/^run_/).map { |s| s.to_s }).uniq
end
runner() click to toggle source

Returns the MiniTest::Unit subclass instance that will be used to run the tests. A MiniTest::Unit instance is the default runner.

# File lib/minitest/unit.rb, line 732
def self.runner
  @@runner ||= self.new
end
runner=(runner) click to toggle source

Tells MiniTest::Unit to delegate to runner, an instance of a MiniTest::Unit subclass, when MiniTest::Unit#run is called.

# File lib/minitest/unit.rb, line 723
def self.runner= runner
  @@runner = runner
end
