3. A Good Test Model : 1) can effectively combine a series of activities. 2) can adapt to each kind of software system with different functions. 3) can find errors in the software design as early as possible. 2

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 No enough detail in test case identifying 6
