The first part of this presentation outlined our basic engineering and test processes to set the context for how our testing matures. The following sections outline how some of the specific test techniques and test cases have been observed and measured to change over time. It is important to note the on-going and product (flight) products. Not all results and data are finalized.
To categorize the changes in the test process we are using classification criteria as seen in figure 2-1, which is taken from [Gardiner 99]. Process evolution has been one of the larger areas of change. We have progressed from older custom build tools to generic commercial products. While doing this we have taken the best from the old and added the new.
