Lesson Transcript
Instructor: Lucinda Stanley

Lucinda has taught business and information technology and has a PhD in Education.

In this lesson, we will explore the dry run testing phase of the software development life cycle. We will consider the process and benefits of dry run testing.

Software Development Life Cycle

Have you ever bought a new piece of software and found yourself saying: ''There are so many bugs I can't even use this software!'' I hope not! But if you have, it's likely because the developer didn't take the time to do some dry run testing of the software before they made it available to users. Testing software is an important part of the software development life cycle.

The Software Development Life Cycle (SDLC) is a framework or process for tasks that need to be accomplished in developing software. The life cycle consists of five processes, including analyzing and planning, defining requirements, developing, testing, and deployment.

Testing actually may happen throughout the development process to find and fix problems. The formal testing phase happens after there has been a needs analysis (what is the purpose of the software), the specific requirements (what do we want it to do) are defined, and the software code is written, but before the software is released to the end user (deployment).

The two types of tests that may be performed are static and dynamic. Static testing is done before a prototype is developed. Dynamic testing is done with a working prototype of the software.

Dry Run Testing

Dry run testing is a static test and should be performed by the developer to mitigate the effects of a failure of the product - meaning before the end user gets the product and discovers it doesn't do what it says it will. In dry run testing, no hardware is used, but it is assumed that the programmer who is testing the code is aware of what each line of code is supposed to do and gives him or her the opportunity to make corrections to the code before it becomes an issue for the actual software. Basically, a dry run test consists of programmers manually reading their code line by line to find errors and fix them. This is a simple Visual Basic code page; a full software application code page would look much more involved.:
