Class Public methods
fixture_paths Link
Returns the ActiveRecord::FixtureSet
collection.
In your test_helper.rb
you must have require "rails/test_help"
.

# File activesupport/lib/active_support/test_case.rb, line 122
fixture_paths=(fixture_paths) Link
Sets the given path to the fixture set.
Can also append multiple paths.
ActiveSupport::TestCase.fixture_paths << "component1/test/fixtures"
In your test_helper.rb
you must have require "rails/test_help"

parallelize(workers: :number_of_processors, with: :processes, threshold: ActiveSupport.test_parallelization_threshold) Link
Parallelizes the test suite.
Takes a workers
argument that controls how many times the process is forked. For each process a new database will be created suffixed with the worker number.
test-database-0
test-database-1
If ENV["PARALLEL_WORKERS"]
is set the workers argument will be ignored and the environment variable will be used instead. This is useful for CI environments, or other environments where you may need more workers than you do for local testing.
If the number of workers is set to 1
or fewer, the tests will not be parallelized.
If workers
is set to :number_of_processors
, the number of workers will be set to the actual core count on the machine you are on.
The default parallelization method is to fork processes. If you’d like to use threads instead you can pass with: :threads
to the parallelize
method. Note the threaded parallelization does not create multiple databases and will not work with system tests.
parallelize(workers: :number_of_processors, with: :threads)
The threaded parallelization uses minitest’s parallel executor directly. The processes parallelization uses a Ruby DRb server.
Because parallelization presents an overhead, it is only enabled when the number of tests to run is above the threshold
param. The default value is 50, and it’s configurable via config.active_support.test_parallelization_threshold
.
# File activesupport/lib/active_support/test_case.rb, line 81 def parallelize(workers: :number_of_processors, with: :processes, threshold: ActiveSupport.test_parallelization_threshold) workers = Concurrent.processor_count if workers == :number_of_processors workers = ENV["PARALLEL_WORKERS"].to_i if ENV["PARALLEL_WORKERS"] Minitest.parallel_executor = ActiveSupport::Testing::ParallelizeExecutor.new(size: workers, with: with, threshold: threshold) end
parallelize_setup(&block) Link
Set up hook for parallel testing. This can be used if you have multiple databases or any behavior that needs to be run after the process is forked but before the tests run.
Note: this feature is not available with the threaded parallelization.
In your test_helper.rb
add the following:
class ActiveSupport::TestCase
parallelize_setup do
# create databases
end
end
parallelize_teardown(&block) Link
Clean up hook for parallel testing. This can be used to drop databases if your app uses multiple write/read databases or other clean up before the tests finish. This runs before the forked process is closed.
Note: this feature is not available with the threaded parallelization.
In your test_helper.rb
add the following:
class ActiveSupport::TestCase
parallelize_teardown do
# drop databases
end
end
test_order() Link
Returns the order in which test cases are run.
ActiveSupport::TestCase.test_order # => :random
Possible values are :random
, :parallel
, :alpha
, :sorted
. Defaults to :random
.
test_order=(new_order) Link
Sets the order in which test cases are run.
ActiveSupport::TestCase.test_order = :random # => :random
Valid values are:
-
:random
(to run tests in random order) -
:parallel
(to run tests in parallel) -
:sorted
(to run tests alphabetically by method name) -
:alpha
(equivalent to:sorted
)
