Test Implementation

Definition

Test implementation is the testing task of implementing the software testing work products.

Objectives

Test implementation typically has the following objectives:

• Implement the test software:
  • Test harnesses.
  • Test procedures.
  • Test scripts.
  • Test suites of test cases.
  • Test data.
• Debug the test software.

Preconditions

Test implementation can typically begin when the following preconditions hold:

• The initiation phase has begun.
• The tests have been planned and designed.

Completion Criteria

Test implementation is typically complete when the following postconditions hold:

• The software test work products have been implemented.

Steps

Test implementation typically involves performing the following steps:

• Program the test harness.
• Program the test scripts.
• Program the test suites of test cases.
• Create the test data (e.g., content).
• Debug the test harness, scripts, suites, cases, and data.

Techniques

Test implementation typically can be performed using the following techniques:

• Pair Programming
• Debugging

Work Products

Test implementation typically results in the production of all or part of the following testing work products:

• Test Harnesses
• Test Scripts
• Test Suites
• Test Cases
• Test Datas

Guidelines

• Because there are often more ways that an application can fail than execute successfully, the amount of test software may well greatly exceed the amount of application software components if robustness is important.
