Test Execution/Evaluation (Do/Check)

You will recall that in the spiral development environment, software testing is described as a continuous improvement process that must be integrated into a rapid application development methodology. Deming’s continuous improvement process using the PDCA model was applied to the software testing process. We are now in the Do/Check part of the spiral model (see Figure 18.1).

Figure 18.2 outlines the steps and tasks associated with the Do/Check part of spiral testing. Each step and task are described along, and valuable tips and techniques are provided.

Step 1: Setup and Testing

Task 1: Regression Test the Manual/Automated Spiral Fixes

The purpose of this task is to retest the tests that discovered ...
