Although there are few benefits of standardized tests‚ it does offer important data. One benefit is how it measures students’ and teachers’ strengths and weaknesses. Standardized tests are given out to measure teacher’s effectiveness in the classroom and a student’s success. The results are then compared amongst others who took the same test. If a student got a higher or lower score than the “standard” score on the test‚ then that is considered his or her strength or weakness. A teacher can then

SOFTWARE TESTING SOFTWARE TESTING Testing is the process of executing a program with the intent of finding errors. TESTING PRINCIPLES All tests should be traceable to customer requirements. Tests should be planned long before testing begins. The Pareto principle applies to software testing. Stated simply‚ the Pareto principle implies that 80 percent of all errors uncovered during testing will likely be traceable to 20 percent of all program components. TESTING PRINCIPLES Testing should begin

1. Can you explain the PDCA cycle and where testing fits in? Software testing is an important part of the software development process. In normal software development there are four important steps‚ also referred to‚ in short‚ as the PDCA (Plan‚ Do‚ Check‚ Act) cycle. Let’s review the four steps in detail. Plan: Define the goal and the plan for achieving that goal. Do/Execute: Depending on the plan strategy decided during the plan stage we do execution accordingly in this phase. Check: Check/Test
