Blog Post #1 JUnit 5 Testing

In class, we have been learning about testing with Junit 5 and doing assignments related to it. After watching the video for the advanced part of the assignment,  I decided that I wanted to research further into the topic for my first blog post. So, what is Junit? In a short answer, JUnit is a Java open sources unit testing framework that is used to write and run repeatable automated tests. JUnit 5 Is the updated version of the highly popular testing library that is Junit 4 which I’m sure you all have heard of it. Junit 5 was released in 2017 that adds good use for Java 8 features. In fact, JUnit 5 requires Java 8 JDK or higher to work.

While researching a few of the key differences between the two versions are Junit 5 is composed of 3 sub-projects JUnit Platform, JUnit Jupiter, and JUnit Vintage. The Assertions and Annotations have been changed, and most importantly Junit 5 adds the support of the lambda expression in which we went over in class. One of the blogs I read recommends doing this example,  which I found quite helpful and easy to understand. The code below is just a conversion between Fahrenheit to Celsius and Junit to test it. The author breaks each part down into subsections which made It easier to follow along. I was also, curious about how Junit 5 worked in the Gradle so I followed tutorials to see how the build systems provide supports to the new feature. I highly recommend watching the video that I have provided; it explains everything you need to know about Junit 5 and the architecture behind It.

Sprint 3 Retrospective

https://gitlab.com/LibreFoodPantry/client-solutions/theas-pantry/reportingsystem Here is the Link to the repositories that contains everything we worked on Sprint-3. Backend, Frontend, Event system, and Keycloak. Connect RabbitMQ receive file to DB : Connected the MongoDB database on the received file. Implement Event System components: Implemented RabbitMq components for Event System. Meet with other Event System Teams. : Met with other teams to finalize everything about messages. New TheasPantryReport: The new Theas Pantry Report Create two channels for both teams: Created two channels for both teams on the send and receive files.   For this Sprint, I worked mainly with Austin on the backend components such as implanting the rabbbitMQ, making API, and trying to get out system working. What worked well / did not work well For this sprint, what worked best was that we got our reporting system functioning. We have a system where the Rabbitmq receives the messa...

Boundary Value Analysis and Equivalence Partitioning Testing

When it comes to a large pool of input data, it is not possible to perform exhausting testing for each set of test data. There should be an easy way to select test cases from the pool so that all scenarios are covered. This is when the Equivalence Partitioning & Boundary Value Analysis testing techniques were introduced. In today’s blog, I want to do further research on the testing technique of Boundary Value Analysis and Equivalence Partitioning Testing. Equivalence Partitioning and Boundary value analysis are linked to each other and can be used together at all levels of software testing. To start, Boundary value testing is the process of testing between extreme boundaries between the partitions, for example like start, end, lower, upper, maximum, minimum, just inside, and outside values. Normally Boundary value analysis is part of stress and negative testing. Using the Boundary Value Analysis technique tester creates test cases for the required input field. Now when it comes t...
