As my final semester approaches here at Worcester State University, I figured a relatable blog topic would be the best practices you can learn as a Software Engineer. The article can be found here: http://www.excella.com/insights/best-software-engineering-practices
This article touches upon three different practices that the author thought highly enough to include. The three practices are S.O.L.I.D., Automated Unit Testing, and continuous integration.
S.O.L.I.D. – an acronym for an object oriented design principle.
S – Single Responsibility – a class should have only a single responsibility.
O – Open/Closed Principle – Software should be open for extension, but closed for modification.
L- Liskov substitution principle – objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
I- Interface Segregation Principle – Many client-specific interfaces are better than one general-purpose interface.
D- Dependency inversion principle – One should depend upon abstractions, not concretions.
When you use all of these principle together, a developer can create code that is much easier to maintain and improve over time. The code is SOLID.
Automated Unit Testing
Automated unit testing is a software development and testing approach where you independently test units to ensure that they are operating correctly. Unit testing can be done manually and it was in the past, but automation has taken over and everyone is thankful for that.
I use JUnit in eclipse to test java programs continuously. It makes it very easy to track where there is an error and what caused it to happen.
Developers become much more confident in their work when they don’t have to worry about wasting a bunch of time finding errors, instead we test immediately and fix the problem before it gets too clustered.
Continuous Integration quite literally means that you continuously ingrate the code and fixing issues before they are submitted to the actual project repository. In my classes we used Github or GitLab to manage repositories.
It works by a developer checking new code submissions in the repository. The integration process then builds and runs tests while analyzing the code. The CI detects any problems with the code and gives feedback to the developer. The developer fixes them and then approves the changes to the code. This way no code ever gets broken.
One of the benefits about using Continuous integration is that the version control system holds all current and changed code. You can easily go back to see what changed and how something may have broke.
