Rake::TaskLib
Create a task that runs a set of tests through rcov, generating code coverage reports.
Example:
require 'rcov/rcovtask' Rcov::RcovTask.new do |t| t.libs << "test" t.test_files = FileList['test/test*.rb'] t.verbose = true end
If rake is invoked with a "TEST=filename" command line option, then the list of test files will be overridden to include only the filename specified on the command line. This provides an easy way to run just one test.
If rake is invoked with a "RCOVOPTS=options" command line option, then the given options are passed to rcov.
If rake is invoked with a "RCOVPATH=path/to/rcov" command line option, then the given rcov executable will be used; otherwise the one in your PATH will be used.
Examples:
rake rcov # run tests normally rake rcov TEST=just_one_file.rb # run just one test file. rake rcov RCOVOPTS="-p" # run in profile mode rake rcov RCOVOPTS="-T" # generate text report
Create a testing task.
# File lib/rcov/rcovtask.rb, line 82 def initialize(name=:rcov) @name = name @libs = ["lib"] @pattern = nil @test_files = nil @verbose = false @warning = false @rcov_opts = ["--text-report"] @ruby_opts = [] @ruby_opts << "--debug" if RUBY_PLATFORM == 'java' @output_dir = "coverage" yield self if block_given? @pattern = 'test/test*.rb' if @pattern.nil? && @test_files.nil? define end
Create the tasks defined by this task lib.
# File lib/rcov/rcovtask.rb, line 99 def define lib_path = @libs.join(File::PATH_SEPARATOR) actual_name = Hash === name ? name.keys.first : name unless Rake.application.last_comment desc "Analyze code coverage with tests" + (@name==:rcov ? "" : " for #{actual_name}") end task @name do run_code = '' RakeFileUtils.verbose(@verbose) do run_code = case rcov_path when nil, '' "-S rcov" else %"#{rcov_path}"! end ruby_opts = @ruby_opts.clone ruby_opts.push( "-I#{lib_path}" ) ruby_opts.push run_code ruby_opts.push( "-w" ) if @warning ruby ruby_opts.join(" ") + " " + option_list + %[ -o "#{@output_dir}" ] + file_list.collect { |fn| %["#{fn}"] }.join(' ') end end desc "Remove rcov products for #{actual_name}" task paste("clobber_", actual_name) do rm_r @output_dir rescue nil end clobber_task = paste("clobber_", actual_name) task :clobber => [clobber_task] task actual_name => clobber_task self end
Explicitly define the list of test files to be included in a test. list is expected to be an array of file names (a FileList is acceptable). If both pattern and test_files are used, then the list of test files is the union of the two.
# File lib/rcov/rcovtask.rb, line 77 def test_files=(list) @test_files = list end
