Tester or Developer- What suits you the most?
These days, there has been an increase in the number of applications that are being developed for various platforms. All these apps require a team of testers and developers in order to ensure that the app is completed within time, scope and budget. The quality of the applications also needs to be top-notch to ensure that no bugs escape out into the wild. However, this may not be as easy as it sounds since the process of developing an application for any platform involves a lot of people working together to ensure that the final product is presentable and usable.
Who is a tester and who is a developer?
In the application development team, there are several different roles that are needed to be filled. The main ones include testers and developers. Perhaps, this is a confusing part for most people as not everyone knows the difference between a tester and a developer. In the next couple of paragraphs, we will take a keen look at each of the tasks and what each entails. This will give you a clear picture of what each role is like. We will also look at some of the ways in which you can get started based on your choice. Read on and discover the amazing world of application development.
Modern applications keep on growing in terms of complexity and features. An application these days requires a complicated set of features that have to work in harmony with each other in order to achieve the overall goal of the system. This is usually stated at the beginning by the party that needs to have the application developed for them. Most of the time, this may be a company or a business that needs to streamline the way in which they carry out their tasks. The developers will then be presented with a proposition for the system and the features that will need to be included in the application. It is upon the developer or team of developers to sit down and break down the features into smaller chunks that can be represented as a computer program. This is done through meetings and collaboration with all the stakeholders that are involved.
Once the features have been nailed down, it is now time to convert these features into actual applications. This is the role of the developer who will use a certain set of tools such as programming languages, data structures, integrated development environments and staging servers to get the system started. A lot of work usually goes into the development of an application since all the features have to be constructed. During the development process, the developer is required to write down and execute basic test cases which will determine whether the application is structurally sound. This is usually done through a process known as unit testing. It is important to note that unit testing is not the same as the testing that is done by the tester. Unit tests are just used to find out whether there are any obvious bugs and that the program works as it was expected. However, there are other bugs which may not be caught early enough by the developer and this is where the tester comes in useful.
A tester is the person responsible for trying out all the usage scenarios for an application in order to ensure that it is working as expected. The tester usually reports back to the development team with the bugs that were discovered and what series of actions led to that particular error. These bugs are usually addressed before the application can be deployed or shipped to the consumers. The work of the tester involves carrying out several activities inside the application as a normal user would do. The tester is usually expected to try out several different approaches to doing the same thing in order to find out a combination of steps that may lead to the program crashing.
It is very important that software bugs are caught early enough to avoid increased costs in case the system fails once it has been deployed in the real world environment. There have been several cases of software failure in the past and this has costs businesses billions in revenue and added costs to fix the bugs. With a tester as part of the development cycle, an application will be shipped with very few bugs since the major ones have been discovered by the tester. In short, the work of the tester is to find bugs before they are caught in the wild. This means that the tester helps to reduce the overall cost of the project and this usually means a lot for a development project.
Tester or Developer?
Your choice usually depends on your particular interests in the world of software development. A developer needs to have programming skills and proficiency at writing code. Development is usually about creating prototypes and testing these prototypes until they are able to function as the developer wanted it. A tester on the other hand is responsible for testing the application and pushing it to its limits. The tester needs to have a knowledge of the system that is being developed and has proper communication skills. This is because the tester will be reporting the bugs back to the development team so that they can work on the errors and fix them. There are a lot of ways in which a person can get started with either of the above. A person who wants to be a developer will usually focus on programming and writing algorithms to solve problems as well as writing the business logic of an application in such a way that it will serve the needs of the customer. On the other hand, a tester will focus on usability and communication so that errors in the application are caught early enough before they become too big or costly. This way, the developers will not have to handle errors once the system has been deployed since they have already been identified by the tester and corrected in time.
