Best Practices for Execution
Once test goals are understood and factors and response variables have been identified, evaluators can generate a formal design to determine exactly how the test will be executed and how many resources will be required to conduct the test. This section also covers practical considerations for carrying out the test and provides access to useful design tools.
A test design is a blueprint that describes factors and levels and how much testing is needed across the factors and levels of your test. Careful design enables you to answer questions of interest.
In this section you will learn about common test designs and techniques for selecting the right test design, as well as the field of Design of Experiments.
Assessing test adequacy is complex. However there are tools and techniques that allow you to compare designs and demonstrate the efficiency and effectiveness of tests.
In this section you will learn about statistical measures of merit that answer the question “How much testing is enough?” and help testers balance test resources with level of certainty in test results.
Conducting a test also involves thinking about logistical nuances and also anticipating how you might respond to problems that arise during the test. An awareness of common issues that interrupt test execution can help reduce the loss of data and even avoid test aborts.
In this section you will learn about many of the practical considerations and constraints that affect testing in defense applications.
Here you can find tools including interactive applications and useful resources to assist with designing and right-sizing a test.
