To add a collaborator to this project you will need to use the Relish gem to add the collaborator via a terminal command. Soon you'll be able to also add collaborators here!
More about adding a collaboratorRspec-subject-extensions 0.3.0
rspec-subject-extensions adds each
short-hand to generate a nested example group with
a single example that specifies the expected value of each attribute of the subject.
If no attribute is given, each element of the subject will be used.
Each
Using the singular name of the attributes
Creates a nested example group named by each
and the submitted attribute
,
and then generates an example for each attribute using the submitted block.
# This ...
describe Object do
each(:item) { should be_an(Integer) }
end
# ... generates the same runtime structure as this:
describe Object do
describe "each item"
it "should be an Integer" do
subject.items.each do |item|
item.should be_an(Integer)
end
end
end
end
The attribute
can be a Symbol
or a String
.
Using no attribute. Ideal to test scopes
Creates a nested example group and then generates an example
for each instance using the submitted block.
# This ...
describe Object do
subject { Object.visible }
each { should be_visible }
end
# ... generates the same runtime structure as this:
describe Object do
describe "each instance" do
it "should be visible" do
subject.each do |element|
element.should be_visible
end
end
end
end
Issues
The documentation for rspec-subject-extensions is a work in progress. We'll be adding
Cucumber features over time, and clarifying existing ones. If you have
specific features you'd like to see added, find the existing documentation
incomplete or confusing, or, better yet, wish to write a missing Cucumber
feature yourself, please submit an issue or a pull request.
