end

#add_filter(filter_argument = nil, &filter_proc) ⇒ Object

Add a filter to the processing chain. There are three ways to define a filter:

  • as a String that will then be matched against all source files’ file paths, SimpleCov.add_filter ‘app/models’ # will reject all your models

  • as a block which will be passed the source file in question and should either return a true or false value, depending on whether the file should be removed SimpleCov.add_filter do |src_file|

    File.basename(src_file.filename) == 'environment.rb'

    end # Will exclude environment.rb files from the results

  • as an instance of a subclass of SimpleCov::Filter. See the documentation there on how to define your own filter classes

# File 'lib/simplecov/configuration.rb', line 186

def add_filter(filter_argument=nil, &filter_proc)
  filters << parse_filter(filter_argument, &filter_proc)
end

#add_group(group_name, filter_argument = nil, &filter_proc) ⇒ Object

Define a group for files. Works similar to add_filter, only that the first argument is the desired group name and files PASSING the filter end up in the group (while filters exclude when the filter is applicable).

# File 'lib/simplecov/configuration.rb', line 195

def add_group(group_name, filter_argument=nil, &filter_proc)
  groups[group_name] = parse_filter(filter_argument, &filter_proc)
end

#at_exit(&block) ⇒ Object

Gets or sets the behavior to process coverage results.

By default, it will call SimpleCov.result.format!

Configure with:

SimpleCov.at_exit do
  puts "Coverage done"
  SimpleCov.result.format!
end

def at_exit(&block)
  return Proc.new {} unless running or block_given?
  @at_exit = block if block_given?
  @at_exit ||= Proc.new { SimpleCov.result.format! }
end

#command_name(name = nil) ⇒ Object

The name of the command (a.k.a. Test Suite) currently running. Used for result merging and caching. It first tries to make a guess based upon the command line arguments the current test suite is running on and should automatically detect unit tests, functional tests, integration tests, rpsec and cucumber and label them properly. If it fails to recognize the current command, the command name is set to the shell command that the current suite is running on.

You can specify it manually with SimpleCov.command_name(“test:units”) - please also check out the corresponding section in README.rdoc

def command_name(name=nil)
  @name = name unless name.nil?
  @name ||= SimpleCov::CommandGuesser.guess
  @name
end

#configure(&block) ⇒ Object

Allows you to configure simplecov in a block instead of prepending SimpleCov to all config methods you’re calling.

SimpleCov.configure do

add_filter 'foobar'

end

This is equivalent to SimpleCov.add_filter ‘foobar’ and thus makes it easier to set a buchn of configure options at once.

# File 'lib/simplecov/configuration.rb', line 114

def configure(&block)
  return false unless SimpleCov.usable?
  instance_exec(&block)
end

#coverage_dir(dir = nil) ⇒ Object

The name of the output and cache directory. Defaults to ‘coverage’

Configure with SimpleCov.coverage_dir(‘cov’)

# File 'lib/simplecov/configuration.rb', line 26

def coverage_dir(dir=nil)
  return @coverage_dir if @coverage_dir and dir.nil?
  @coverage_dir = (dir || 'coverage')
end

#coverage_path ⇒ Object

Returns the full path to the output directory using SimpleCov.root and SimpleCov.coverage_dir, so you can adjust this by configuring those values. Will create the directory if it’s missing

# File 'lib/simplecov/configuration.rb', line 36

def coverage_path
  coverage_path = File.join(root, coverage_dir)
  FileUtils.mkdir_p coverage_path
  coverage_path
end

#merge_timeout(seconds = nil) ⇒ Object

Defines them maximum age (in seconds) of a resultset to still be included in merged results. i.e. If you run cucumber features, then later rake test, if the stored cucumber resultset is more seconds ago than specified here, it won’t be taken into account when merging (and is also purged from the resultset cache)

Of course, this only applies when merging is active (e.g. SimpleCov.use_merging is not false!)

Default is 600 seconds (10 minutes)

Configure with SimpleCov.merge_timeout(3600) # 1hr

# File 'lib/simplecov/configuration.rb', line 167

def merge_timeout(seconds=nil)
  @merge_timeout = seconds if !seconds.nil? and seconds.kind_of?(Fixnum)
  @merge_timeout ||= 600
end

#nocov_token(nocov_token = nil) ⇒ Object Also known as: skip_token

Certain code blocks (i.e. Ruby-implementation specific code) can be excluded from the coverage metrics by wrapping it inside # :nocov: comment blocks. The nocov token can be configured to be any other string using this.

Configure with SimpleCov.nocov_token(‘skip’) or it’s alias SimpleCov.skip_token(‘skip’)

  @nocov_token = (nocov_token || 'nocov')
end

#project_name(new_name = nil) ⇒ Object

Returns the project name - currently assuming the last dirname in the SimpleCov.root is this.

  @project_name = new_name if new_name.kind_of?(String)
  @project_name ||= File.basename(root.split('/').last).capitalize.gsub('_', ' ')
end

#root(root = nil) ⇒ Object

The root for the project. This defaults to the current working directory.

Configure with SimpleCov.root(‘/my/project/path’)

  @root = File.expand_path(root || Dir.getwd)
end

#use_merging(use = nil) ⇒ Object

Defines whether to use result merging so all your test suites (test:units, test:functionals, cucumber, …) are joined and combined into a single coverage report

end
