Derin's CS Journey

For the last and final blog for the CS 433 class, I want to focus on an interesting topic that is automation testing. Nowadays, most companies have implemented automated testing environments. It is the best way to increase effectiveness, test coverage, and the execution speed of software testing. Before I get started, what exactly is automation testing? Well, automation testing or Test automation is a software testing technique that performs using various software tools to execute a test case suite. The automation testing software can enter test data into the system and compare expected and actual results with the generated details test reports. There several benefits of using test automation, it is the best way to increase effectiveness and save money. Other factors include manual testing, which is time-consuming, Test automation does not require human intervention and can run automated tests unattended or even overnight, it is reliable in results, improve accuracy, better speed, and ...

During class, we have been doing many testing methods including Junit 5 and for the past two weeks we have been using Mockito, so for today’s blog, I want to focus more on the framework and testing with Mockito. Before we get started let us talk about what is mocking. Mocking is a process of developing the objects that act as the mock or clone of the real objects. In another word, mocking is a technique where mock objects are used instead of real objects. The purpose is to isolate and focus on the code being tested. Mock uses objects such as Fakes, Stubs, and mocks. A fake object has working implementation but takes shortcuts which makes them not suitable for production. Stub object usually does not respond to anything outside that is programmed in for the test. Mocks are objects that are preprogrammed with expectations which form a specification of the call that is called to receive. Now let us move on to what Mockito is, Mockito is a java based mocking framework ...

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...

In class, we have been learning about the different types of testing methods. Today I want to focus on Black-Box vs. White-Box testing. Let us start by looking at how each test method differs from the other. Black Box testing is a software method in which the internal structure design and implementation of the item being tested are not known to the tester. However, in white box testing, the internal structure, design, and implementation are known to the tester. Let us start by looking at a diagram example that was provided in one of my resources for black-box testing. The picture above of Black Box testing can be any software system. For example, a website like a google or an amazon database. All under the Black Box testing, you can test the applications by just focusing on the inputs and outputs without knowing their internal code implementation. There are many types of black box testing methods, but the main types are functional, nonfunctional and regression testing.   Now let ...

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 recommen...

Hello Everyone, I'm Derin Sabu, this is my introductory blog post for CS-443 and CS-448. Excited and looking forward to learning new concepts. It won’t be easy, but it is worth it.  Good Luck!
