Hello dear reader. This is my last blog for my Software Construction and Design and as a very important part of development I choose to talk in this blog post for REST API.

REST API stands for Representational State Transferee and provides a lighter weight compared to SOAP. Instead of using XML to make a request, REST relies on a simple URL in many cases. In some situations, additional information needs to be provided. Most Web services using REST rely exclusively on obtaining the needed information using the URL approach. REST can use four different HTTP verbs (GET, POST, PUT, and DELETE) to perform tasks.
REST-based Web services output the data in Command Separated Value (CSV), JavaScript Object Notation (JSON) and Really Simple Syndication (RSS). The point is that you can keep the output you need in a form that’s easy to understand and use within the language you are using for your application. The information you receive when using REST is a JSON formatted document containing the information you asked for. You can use your browser to interact with the Web service, which makes it a lot easier to create the right URL and verify the output you need to parse with your application.
In most of the part REST is easier and more flexible to use. To use REST you do not need to purchase any tools, Postman or Insomnia can be downloaded for free. REST though, is efficient as it uses the small message formats and it has a fast process.
There are some very strong reasons that you should be using REST. First, REST is the most popular choice of programmers to build APIs.  Also REST API is great on making the data available as a resource as opposed to service.
To create a REST API, the following six architectural constraints are needed: 1. Uniform interface, which means that the same resource should not have more than one URL; 2. Client-server separating, which means that the client and the server should act independently. 3. Statelessness, which means that there should never be any server-side sessions; 4. Cacheable resources, means that the server responses should contain information even though the data sent might or not be cacheable; 5.Layered system, which means there might be different layers of servers between the client and the server that returns the purpose; 6. Code on demands, which means that the response can contain code that the user can execute.

If I also refer to the previous blog about SOAP API I would say that there are clearly good reasons why REST API is a better choice to use when requesting/ expecting data and when you want to build your own program. However the decision is yours. I hope I have helped your CS journey. Till next time…

And the biggest question if the software testing is manual testing vs automatic testing? Why do we need automated testing?

@All Welcome to my last blog post for my Software Test class. As a last blog post for this class I wanted to talk about the Automated Testing.

From the name we can tell that Automated Testing is automated. Automated testing is done through an automated tool, which is needed in exploratory tests and in maintaining test scripts while increasing overall test coverage. Automated Testing is usually used for large projects that require testing the same area lots of times.
Automated Testing has its own implementing strategy which consist in the shape of a pyramid. This strategy calls for automating testing at three different levels. The biggest percentage of this test automation pyramid goes to unit testing. The is followed from API testing and UI testing.

Software tests have to repeated often during development cycles to ensure quality. Every time the source code is modified, software test should be repeated. From my experience at my work, we recently automated the testing and deployment process for one of our systems. For every deployment, we had to test every connected system. One of the benefits of Automated Testing is that is much faster than the manual testing and it also can reduce the time to run repetitive tests all the time. In my opinion time savings equals cost savings. Another benefit of Automated Testing is it increases the test coverage.  It can easily execute thousands of different complex test cases during every test run, providing coverage that is almost impossible with manual testing.

Kyle makes a good point in explaining the differences between the test automation and automated testing as its important to know the difference.
