Overview

Create a task that runs a set of tests.

Example:

Rake::TestTask.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 “TESTOPTS=options” command line option, then the given options are passed to the test process after a '–'. This allows ::Test::Unit options to be passed to the test suite.

Examples:

rake test                           # run tests normally
rake test TEST=just_one_file.rb     # run just one test file.
rake test TESTOPTS="-v"             # run in verbose mode
rake test TESTOPTS="--runner=fox"   # use the fox test runner
