Class Method Details

.pending(description, &block) ⇒ Object

This method will define a test method using the description as the test name (“pending function” => “test_pending_function”)

Instead of doing this:

def test_function_is_pending

pending "this test is pending"

end

You can just do this:

pending “function is pending”

This method can be called with a block passed, the same as the instance method

Instance Method Details

#pending(description = "", &block) ⇒ Object

The pending method lets you define a block of test code that is currently “pending” functionality.

You can use it two ways. One is simply put a string as the parameter:

def test_web_service_integration
  pending "This is not done yet..."
end

This will output a “P” in the test output alerting there is pending functionality.

You can also supply a block of code:

def test_new_helpers
  pending "New helpers for database display" do
    output = render_record(User.first)
    assert_equal "Jerry User ([email protected])", output
  end
end

If the block doesn’t fail, then the test will flunk with output like:

<New helpers for database display> did not fail.

If the test fails (i.e., the functionality isn’t implemented), then it will not fail the surrounding test.
