Add a filter to the processing chain. There are four 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 array of strings that are matched against all sorce files' file paths and then ignored (basically string filter multiple times)
SimpleCov.add_filter ['app/models', 'app/helpers'] # ignores both dirs
-
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 276 def add_filter(filter_argument = nil, &filter_proc) filters << parse_filter(filter_argument, &filter_proc) end
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 285 def add_group(group_name, filter_argument = nil, &filter_proc) groups[group_name] = parse_filter(filter_argument, &filter_proc) end
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
# File lib/simplecov/configuration.rb, line 178 def at_exit(&block) return proc {} unless running || block_given? @at_exit = block if block_given? @at_exit ||= proc { SimpleCov.result.format! } end
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
# File lib/simplecov/configuration.rb, line 82 def command_name(name = nil) @name = name unless name.nil? @name ||= SimpleCov::CommandGuesser.guess @name end
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 bunch of configure options at once.
# File lib/simplecov/configuration.rb, line 161 def configure(&block) return false unless SimpleCov.usable? Docile.dsl_eval(self, &block) end
The name of the output and cache directory. Defaults to 'coverage'
Configure with SimpleCov.coverage_dir('cov')
# File lib/simplecov/configuration.rb, line 30 def coverage_dir(dir = nil) return @coverage_dir if defined?(@coverage_dir) && dir.nil? @coverage_path = nil # invalidate cache @coverage_dir = (dir || "coverage") end
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 41 def coverage_path @coverage_path ||= begin coverage_path = File.expand_path(coverage_dir, root) FileUtils.mkdir_p coverage_path coverage_path end end
Returns the list of configured filters. Add filters using SimpleCov.add_filter.
# File lib/simplecov/configuration.rb, line 69 def filters @filters ||= [] end
Gets or sets the configured formatter.
Configure with: SimpleCov.formatter(SimpleCov::Formatter::SimpleFormatter)
# File lib/simplecov/configuration.rb, line 93 def formatter(formatter = nil) return @formatter if defined?(@formatter) && formatter.nil? @formatter = formatter raise "No formatter configured. Please specify a formatter using SimpleCov.formatter = SimpleCov::Formatter::SimpleFormatter" unless @formatter @formatter end
Gets the configured formatters.
# File lib/simplecov/configuration.rb, line 110 def formatters if @formatter.is_a?(SimpleCov::Formatter::MultiFormatter) @formatter.formatters else Array(formatter) end end
Sets the configured formatters.
# File lib/simplecov/configuration.rb, line 103 def formatters=(formatters) @formatter = SimpleCov::Formatter::MultiFormatter.new(formatters) end
Returns the configured groups. Add groups using SimpleCov.add_group
# File lib/simplecov/configuration.rb, line 134 def groups @groups ||= {} end
Defines the maximum coverage drop at once allowed for the testsuite to pass. SimpleCov will return non-zero if the coverage decreases by more than this threshold.
Default is 100% (disabled)
# File lib/simplecov/configuration.rb, line 236 def maximum_coverage_drop(coverage_drop = nil) @maximum_coverage_drop ||= (coverage_drop || 100).to_f.round(2) end
Defines the 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 215 def merge_timeout(seconds = nil) @merge_timeout = seconds if seconds.is_a?(Integer) @merge_timeout ||= 600 end
Defines the minimum overall coverage required for the testsuite to pass. SimpleCov will return non-zero if the current coverage is below this threshold.
Default is 0% (disabled)
# File lib/simplecov/configuration.rb, line 226 def minimum_coverage(coverage = nil) @minimum_coverage ||= (coverage || 0).to_f.round(2) end
Defines the minimum coverage per file required for the testsuite to pass. SimpleCov will return non-zero if the current coverage of the least covered file is below this threshold.
Default is 0% (disabled)
# File lib/simplecov/configuration.rb, line 247 def minimum_coverage_by_file(coverage = nil) @minimum_coverage_by_file ||= (coverage || 0).to_f.round(2) end
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')
# File lib/simplecov/configuration.rb, line 125 def nocov_token(nocov_token = nil) return @nocov_token if defined?(@nocov_token) && nocov_token.nil? @nocov_token = (nocov_token || "nocov") end
Returns the hash of available profiles
# File lib/simplecov/configuration.rb, line 141 def profiles @profiles ||= SimpleCov::Profiles.new end
Returns the project name - currently assuming the last dirname in the SimpleCov.root is this.
# File lib/simplecov/configuration.rb, line 188 def project_name(new_name = nil) return @project_name if defined?(@project_name) && @project_name && new_name.nil? @project_name = new_name if new_name.is_a?(String) @project_name ||= File.basename(root.split("/").last).capitalize.tr("_", " ") end
Refuses any coverage drop. That is, coverage is only allowed to increase. SimpleCov will return non-zero if the coverage decreases.
# File lib/simplecov/configuration.rb, line 255 def refuse_coverage_drop maximum_coverage_drop 0 end
The root for the project. This defaults to the current working directory.
Configure with SimpleCov.root('/my/project/path')
# File lib/simplecov/configuration.rb, line 20 def root(root = nil) return @root if defined?(@root) && root.nil? @root = File.expand_path(root || Dir.getwd) end
Coverage results will always include files matched by this glob, whether or not they were explicitly required. Without this, un-required files will not be present in the final report.
# File lib/simplecov/configuration.rb, line 54 def track_files(glob) @tracked_files = glob end
Returns the glob that will be used to include files that were not explicitly required.
# File lib/simplecov/configuration.rb, line 62 def tracked_files @tracked_files if defined?(@tracked_files) end
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
# File lib/simplecov/configuration.rb, line 198 def use_merging(use = nil) @use_merging = use unless use.nil? @use_merging = true unless defined?(@use_merging) && @use_merging == false end
