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 collaborator`have_attributes` matcher
Use the have_attributes matcher to specify that an object's attributes match the expected attributes:
Person = Struct.new(:name, :age)
person = Person.new("Jim", 32)
expect(person).to have_attributes(:name => "Jim", :age => 32)
expect(person).to have_attributes(:name => a_string_starting_with("J"), :age => (a_value > 30) )
The matcher will fail if actual doesn't respond to any of the expected attributes:
expect(person).to have_attributes(:name => "Jim", :color => 'red')
- Scenarios
-
- basic usage
-
- Given
-
a file named "basic_have_attributes_matcher_spec.rb" with:
Person = Struct.new(:name, :age) RSpec.describe Person.new("Jim", 32) do it { is_expected.to have_attributes(:name => "Jim") } it { is_expected.to have_attributes(:name => a_string_starting_with("J") ) } it { is_expected.to have_attributes(:age => 32) } it { is_expected.to have_attributes(:age => (a_value > 30) ) } it { is_expected.to have_attributes(:name => "Jim", :age => 32) } it { is_expected.to have_attributes(:name => a_string_starting_with("J"), :age => (a_value > 30) ) } it { is_expected.not_to have_attributes(:name => "Bob") } it { is_expected.not_to have_attributes(:age => 10) } it { is_expected.not_to have_attributes(:age => (a_value < 30) ) } # deliberate failures it { is_expected.to have_attributes(:name => "Bob") } it { is_expected.to have_attributes(:age => 10) } # fails if any of the attributes don't match it { is_expected.to have_attributes(:name => "Bob", :age => 32) } it { is_expected.to have_attributes(:name => "Jim", :age => 10) } it { is_expected.to have_attributes(:name => "Bob", :age => 10) } end - When
-
I run
rspec basic_have_attributes_matcher_spec.rb - Then
- the output should contain "14 examples, 5 failures"
