class Minitest::Runnable

Represents anything “runnable”, like Test, Spec, Benchmark, or whatever you can dream up.

Subclasses of this are automatically registered and available in Runnable.runnables.

Attributes

assertions [RW]

Number of assertions executed in this run.

failures [RW]

An assertion raised during the run, if any.

metadata [W]

Sets metadata, mainly used for Result.from.

time [RW]

The time it took to run.

Public Class Methods

methods_matching (re)

Returns all instance methods matching the pattern re.

# File lib/minitest.rb, line 390
def self.methods_matching re
  public_instance_methods(true).grep(re).map(&:to_s)
end

run (reporter, options = {})

Responsible for running all runnable methods in a given class, each in its own instance. Each instance is passed to the reporter to record.

# File lib/minitest.rb, line 405
def self.run reporter, options = {}
  pos = options[:filter]
  neg = options[:exclude]

  pos = Regexp.new $1 if pos.kind_of?(String) && pos =~ %r%/(.*)/%
  neg = Regexp.new $1 if neg.kind_of?(String) && neg =~ %r%/(.*)/%

  filtered_methods = self.runnable_methods
    .select { |m| !pos ||  pos === m || pos === "#{self}##{m}"  }
    .reject { |m|  neg && (neg === m || neg === "#{self}##{m}") }

  return if filtered_methods.empty?

  t0 = name = nil

  @_info_handler = lambda do
    unless reporter.passed? then
      warn "Current results:"
      warn reporter.reporters.grep(SummaryReporter).first
    end

    warn "Current: %s#%s %.2fs" % [self, name, Minitest.clock_time - t0]
  end

  with_info_handler reporter do
    filtered_methods.each do |method_name|
      name = method_name
      t0 = Minitest.clock_time

      run_one_method self, method_name, reporter
    end
  end
end

run_one_method (klass, method_name, reporter)

Runs a single method and has the reporter record the result. This was considered internal API but is factored out of run so that subclasses can specialize the running of an individual test. See Minitest::ParallelTest::ClassMethods for an example.

# File lib/minitest.rb, line 445
def self.run_one_method klass, method_name, reporter
  reporter.prerecord klass, method_name
  reporter.record Minitest.run_one_method(klass, method_name)
end

runnable_methods ()

Each subclass of Runnable is responsible for overriding this method to return all runnable methods. See methods_matching.

# File lib/minitest.rb, line 481
def self.runnable_methods
  raise NotImplementedError, "subclass responsibility"
end

runnables ()

Returns all subclasses of Runnable.

# File lib/minitest.rb, line 488
def self.runnables
  @@runnables
end

test_order ()

Defines the order to run tests (:random by default). Override this or use a convenience method to change it for your tests.

# File lib/minitest.rb, line 454
def self.test_order
  :random
end

Public Instance Methods

metadata ()

Metadata you attach to the test results that get sent to the reporter.

Lazily initializes to a hash, to keep memory down.

NOTE: this data must be plain (read: marshal-able) data! Hashes! Arrays! Strings!

# File lib/minitest.rb, line 527
def metadata
  @metadata ||= {}
end

metadata? ()

Returns true if metadata exists.

# File lib/minitest.rb, line 539
def metadata?
  defined? @metadata
end

name ()

Name of the run.

# File lib/minitest.rb, line 376
def name
  @NAME
end

name= (o)

Set the name of the run.

# File lib/minitest.rb, line 383
def name= o
  @NAME = o
end

passed? ()

Did this run pass?

Note: skipped runs are not considered passing, but they don’t cause the process to exit non-zero.

# File lib/minitest.rb, line 556
def passed?
  raise NotImplementedError, "subclass responsibility"
end

result_code ()

Returns a single character string to print based on the result of the run. One of ".", "F", "E" or "S".

# File lib/minitest.rb, line 565
def result_code
  raise NotImplementedError, "subclass responsibility"
end

run ()

Runs a single method. Needs to return self.

# File lib/minitest.rb, line 546
def run
  raise NotImplementedError, "subclass responsibility"
end

skipped? ()

Was this run skipped? See passed? for more information.

# File lib/minitest.rb, line 572
def skipped?
  raise NotImplementedError, "subclass responsibility"
end
