Getting Started

• First you need to make the two CDD tool windows 'Testing' and 'CDD Output' visible. Do that by going to the menu 'View -> Tools' and select 'Testing' and 'CDD Output':

• Now enable background execution and extraction of test cases. The first will cause the execution of your test cases after every compilation and the second will extract a new test case after every exception. To enable both make sure both of the toolbar buttons (marked in red) below are pressed.

How to add a manual test case

To add a manual test case simply create a new class whose name contains the word 'TEST', have it inherit from CDD_TEST_CASE and add one or several unit test routines. Make sure that all unit test routines start with 'test_'. Here is a simple example test class:

class TEST_BANK_ACCOUNT
inherit CDD_TEST_CASE
feature
  test_deposit
    local
      ba: BANK_ACCOUNT
    do
      create ba.make_with_balance (0)
      ba.deposit (100)
      check
         money_depisited: ba.balance = 100
      end
    end
end

After you have added your test class, recompile and your test case should automatially appear in the 'Testing' tool window. A template test case can created by pressing the 'Create new manual test case' button:

How to extract a test case

CDD automatically extracts a new test case after every thrown exception. This test case will appear in the normal test case tool window and can be managed like an ordinary manually written test case.

How to search for a test case

Use the filter text box to search for test case by name or tag. Make sure you press enter after you have changed the filter text.

How to add a tag to a test case

You can add custom tags to test cases by adding a indexing item 'tag' to either the test class or the test routine. Here is an example of a test class with a tag:

indexing
  tag: "fixme"
class TEST_BANK_ACCOUNT
inherit CDD_TEST_CASE
feature
  test_deposit
    local
      ba: BANK_ACCOUNT
    do
      create ba.make_with_balance (0)
      ba.deposit (100)
      check
         money_depisited: ba.balance = 100
      end
    end
end

How to restrict test case execution

If the 'Restrict' push-button is pressed, only test cases matching the current filter criterion (i.e. test cases that show up in the tree-view) will be executed. You can use this to shorten testing time when working on a particular subset of your program.
