Overview

Spec – The faster, better, less-magical spec framework!

For a list of expectations, see Expectations.

Class Method Summary

DSL - Extended

after	Define an 'after' action.
before	Define a 'before' action.
it	Define an expectation with name `desc`.
let	Essentially, define an accessor for `name` with `block`.
register_spec_type	Register a new type of spec that matches the spec's description.
spec_type	Figure out the spec class to use based on a spec's description.
specify	Alias for DSL#it.
subject	Another lazy man's accessor generator.

Test - Inherited

.i_suck_and_my_tests_are_order_dependent!	Call this at the top of your tests when you absolutely positively need to have ordered tests.
.make_my_diffs_pretty!	Make diffs for this Test use `#pretty_inspect` so that diff in assert_equal can have more details.
.parallelize_me!	Call this at the top of your tests when you want to run your tests in parallel.
.runnable_methods	Returns all instance methods starting with “test_”.
.test_order	Defines the order to run tests (:random by default).

Guard - Extended

jruby?	Is this running on jruby?
maglev?	Is this running on maglev?
mri?	Is this running on mri?
osx?	Is this running on macOS?
rubinius?	Is this running on rubinius?
windows?	Is this running on windows?

Runnable - Inherited

.methods_matching	Returns all instance methods matching the pattern `re`.
.run	Responsible for running all runnable methods in a given class, each in its own instance.
.run_one_method	Runs a single method and has the reporter record the result.
.runnable_methods	Each subclass of Runnable is responsible for overriding this method to return all runnable methods.
.runnables	Returns all subclasses of Runnable.

Instance Attribute Summary

Reportable - Included

#error?	Did this run error?
#passed?	Did this run pass?
#skipped?	Was this run skipped?

Assertions - Included

#skipped?

Was this testcase skipped? Meant for #teardown.

Runnable - Inherited

#assertions	Number of assertions executed in this run.
#failures	An assertion raised during the run, if any.
#name	Name of the run.
#name=	Set the name of the run.
#time	The time it took to run.
#passed?	Did this run pass?
#skipped?	Was this run skipped? See `#passed?` for more information.

Instance Method Summary

Test - Inherited

#run	Runs a single test with setup/teardown hooks.

Guard - Included

#jruby?	Is this running on jruby?
#maglev?	Is this running on maglev?
#mri?	Is this running on mri?
#osx?	Is this running on macOS?
#rubinius?	Is this running on rubinius?
#windows?	Is this running on windows?

Test::LifecycleHooks - Included

#after_setup	Runs before every test, after setup.
#after_teardown	Runs after every test, after teardown.
#before_setup	Runs before every test, before setup.
#before_teardown	Runs after every test, before teardown.
#setup	Runs before every test.
#teardown	Runs after every test.

Reportable - Included

#location	The location identifier of this test.
#result_code	Returns “.”, “F”, or “E” based on the result of the run.

Assertions - Included

#assert	Fails unless `test` is truthy.
#assert_empty	Fails unless `obj` is empty.
#assert_equal	Fails unless `exp == act` printing the difference between the two, if possible.
#assert_in_delta	For comparing Floats.
#assert_in_epsilon	For comparing Floats.
#assert_includes	Fails unless `collection` includes `obj`.
#assert_instance_of	Fails unless `obj` is an instance of `cls`.
#assert_kind_of	Fails unless `obj` is a kind of `cls`.
#assert_match	Fails unless `matcher` `=~` `obj`.
#assert_mock	Assert that the mock verifies correctly.
#assert_nil	Fails unless `obj` is nil.
#assert_operator	For testing with binary operators.
#assert_output	Fails if stdout or stderr do not output the expected results.
#assert_path_exists	Fails unless `path` exists.
#assert_predicate	For testing with predicates.
#assert_raises	Fails unless the block raises one of `exp`.
#assert_respond_to	Fails unless `obj` responds to `meth`.
#assert_same	Fails unless `exp` and `act` are `#equal?`
#assert_send	`send_ary` is a receiver, message and arguments.
#assert_silent	Fails if the block outputs anything to stderr or stdout.
#assert_throws	Fails unless the block throws `sym`
#capture_io	Captures $stdout and $stderr into strings:
#capture_subprocess_io	Captures $stdout and $stderr into strings, using Tempfile to ensure that subprocess IO is captured as well.
#diff	Returns a diff between `exp` and `act`.
#exception_details	Returns details for exception `e`
#fail_after	Fails after a given date (in the local time zone).
#flunk	Fails with `msg`.
#message	Returns a proc that will output `msg` along with the default message.
#mu_pp	This returns a human-readable version of `obj`.
#mu_pp_for_diff	This returns a diff-able more human-readable version of `obj`.
#pass	used for counting assertions.
#refute	Fails if `test` is truthy.
#refute_empty	Fails if `obj` is empty.
