DSL - Extended

after

Define an 'after' action.

before

Define a 'before' action.

children

Returns the children of this spec.

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.

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_”.

Guard - Extended

jruby?

Is this running on jruby?

maglev?

Is this running on maglev?

mri?

Is this running on mri?

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,
.runnable_methods

Each subclass of Runnable is responsible for overriding this method to return all runnable methods.

.runnables

Returns all subclasses of Runnable.

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.

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_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_predicate

For testing with predicates.

#assert_raises

Fails unless the block raises one of exp.

#assert_respond_to

Fails unless obj responds to meth.
