Automated Testing

  • Automated Testing Part 1

    Testing. Everybody claims to do it, but few do it well. Throwing random input at a program to see what happens is not true testing. As for "regression testing"? Testing everything that has been tested before to PROVE the new changes haven't broken something? The mind boggles. The first part of this series starts to explore how the "main stream" (non-MultiValue) developers do it, and why MultiValue will always be considered archaic if we don't get on board.

  • Automated Testing Part 2 - Unit Tests

    Unit Tests are a fundamental building block in the modern Test Driven Design method of software development. Unfortunately, most of the literature on the subject concentrates on objectoriented design and programming. Even though several of our MultiValue platforms now support object-orientation, our legacy code from years ago does not. Second in a series, this article explores both the concept of Unit Tests and how to implement them in our non-object oriented environment.

  • Automated Testing Part 3: Integration Testing

    Part 1 of this series explained how "mainstream" technologies develop and use automated testing and makes the case for pulling MultiValue testing methodologies into the 21st century if we are to continue to be seen as a viable application development platform. Part 2 tackled the topic of the Unit Test and how we might implement it in a well structured MultiValue solution. This article moves on to the topic of Integration Testing — do all the pieces fit together and work properly?

  • Automated Testing Part 4: Legacy Code

    The first three articles in this series introduced the concepts of automated testing, test driven development, and explored the details of unit testing and integration testing. This article digs into the real-world problem most MultiValue developers grapple with on a day-to-day basis — trying to flog old legacy code into the 21st century.

  • Automated Testing Part 5: Dependencies

    The previous article looked at techniques for refactoring legacy code to expose individual functional pieces for unit testing. Although unit tests for individual routines is fairly straightforward, putting them all together and testing the whole can be challenging. The fifth article in this series examines some of the problems and techniques for handling these issues.
