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"be" matchers
There are several related "be" matchers:
obj.should be_true # passes if obj is truthy (not nil or false)
obj.should be_false # passes if obj is falsy (nil or false)
obj.should be_nil # passes if obj is nil
obj.should be # passes if obj is truthy (not nil or false)
- Scenarios
-
- be_true matcher
-
- Given
-
a file named "be_true_spec.rb" with:
describe "be_true matcher" do specify { true.should be_true } specify { 7.should be_true } specify { "foo".should be_true } specify { nil.should_not be_true } specify { false.should_not be_true } # deliberate failures specify { true.should_not be_true } specify { 7.should_not be_true } specify { "foo".should_not be_true } specify { nil.should be_true } specify { false.should be_true } end
- When
-
I run
rspec be_true_spec.rb
- Then
- the output should contain "10 examples, 5 failures"
- And
-
the output should contain:
expected: non-true value got: true
- And
-
the output should contain:
expected: non-true value got: 7
- And
-
the output should contain:
expected: non-true value got: "foo"
- And
-
the output should contain:
expected: true value got: nil
- And
-
the output should contain:
expected: true value got: false
- be_false matcher
-
- Given
-
a file named "be_false_spec.rb" with:
describe "be_false matcher" do specify { nil.should be_false } specify { false.should be_false } specify { true.should_not be_false } specify { 7.should_not be_false } specify { "foo".should_not be_false } # deliberate failures specify { nil.should_not be_false } specify { false.should_not be_false } specify { true.should be_false } specify { 7.should be_false } specify { "foo".should be_false } end
- When
-
I run
rspec be_false_spec.rb
- Then
- the output should contain "10 examples, 5 failures"
- And
-
the output should contain:
expected: non-false value got: nil
- And
-
the output should contain:
expected: non-false value got: false
- And
-
the output should contain:
expected: false value got: true
- And
-
the output should contain:
expected: false value got: 7
- And
-
the output should contain:
expected: false value got: "foo"
- be_nil matcher
-
- Given
-
a file named "be_nil_spec.rb" with:
describe "be_nil matcher" do specify { nil.should be_nil } specify { false.should_not be_nil } specify { true.should_not be_nil } specify { 7.should_not be_nil } specify { "foo".should_not be_nil } # deliberate failures specify { nil.should_not be_nil } specify { false.should be_nil } specify { true.should be_nil } specify { 7.should be_nil } specify { "foo".should be_nil } end
- When
-
I run
rspec be_nil_spec.rb
- Then
- the output should contain "10 examples, 5 failures"
- And
-
the output should contain:
expected: not nil got: nil
- And
-
the output should contain:
expected: nil got: false
- And
-
the output should contain:
expected: nil got: true
- And
-
the output should contain:
expected: nil got: 7
- And
-
the output should contain:
expected: nil got: "foo"
- be matcher
-
- Given
-
a file named "be_spec.rb" with:
describe "be_matcher" do specify { true.should be } specify { 7.should be } specify { "foo".should be } specify { nil.should_not be } specify { false.should_not be } # deliberate failures specify { true.should_not be } specify { 7.should_not be } specify { "foo".should_not be } specify { nil.should be } specify { false.should be } end
- When
-
I run
rspec be_spec.rb
- Then
-
the output should contain all of these:
10 examples, 5 failures expected true to evaluate to false expected 7 to evaluate to false expected "foo" to evaluate to false expected nil to evaluate to true expected false to evaluate to true
