  1. Improving the ICM Test Planning and Identification Qian Wu April 23,2010

  2. Agenda • Agood test model • Current approach • Problems • New approach • Benefits • References 1

  3. A Good Test Model : • can effectively combine a series of activities. • can adapt to each kind of software system with different functions. • can find errors in the software design as early as possible. 2

  4. Current Approach • Test Plan and Cases • Test Procedures and Results • Regression Test Package 3

  5. Current Approach 4

  6. Test Cases could be identified by using the following structure: • Test Identifier: This identifies the test by a project unique identifier and test case name. It shall provide a brief description of the test • Test Level : describe the level at which the testing will be performed, for example, software item level or system performance (level of service) level. • Test Class : describe the type or class of the test that will be performed, for example, timing tests, erroneous tests, maximum capacity tests, etc. • Test Completion Criteria: list of completion criteria specific for this test identifier • Test Cases: A test case specification specifies inputs, expected results, and a set of execution conditions for a test item. For each test case, create a sub-heading using the following structure:Identify a test (one of the tests in the test set comprising the application testing addressed by this test description) by a project-unique identifier and provide the information specified below for the test. The name includes the identification of the applicable unit. There may be several test cases for one test identifier. 5

  7. Current Approach Problems: • Develop test plan and test cases too late • Noenough detail in test case identifying 6

  8. New Approach • Develop Condition tree • Develop Behavior tree 7
