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`start_with` matcher
Use the start_with matcher to specify that a string or array starts with the expected
characters or elements.
expect("this string").to start_with("this")
expect("this string").not_to start_with("that")
expect([0,1,2]).to start_with(0, 1)
- Scenarios
-
- with a string
-
- Given
-
a file named "example_spec.rb" with:
RSpec.describe "this string" do it { is_expected.to start_with "this" } it { is_expected.not_to start_with "that" } # deliberate failures it { is_expected.not_to start_with "this" } it { is_expected.to start_with "that" } end - When
-
I run
rspec example_spec.rb - Then
-
the output should contain all of these:
4 examples, 2 failures expected "this string" not to start with "this" expected "this string" to start with "that"
- with an array
-
- Given
-
a file named "example_spec.rb" with:
RSpec.describe [0, 1, 2, 3, 4] do it { is_expected.to start_with 0 } it { is_expected.to start_with(0, 1)} it { is_expected.not_to start_with(2) } it { is_expected.not_to start_with(0, 1, 2, 3, 4, 5) } # deliberate failures it { is_expected.not_to start_with 0 } it { is_expected.to start_with 3 } end - When
-
I run
rspec example_spec.rb - Then
-
the output should contain all of these:
6 examples, 2 failures expected [0, 1, 2, 3, 4] not to start with 0 expected [0, 1, 2, 3, 4] to start with 3
