Difference under the perspective of “Testers” and “Developers”

In this article, we will see the different views of Testers and Developers and their relationships to make a perfect application.

The purpose of Testers and Developers is the same, both want to provide a quality product to customers. But their way of thinking is different.

It is not wrong to say: “Testers and Developers are not different, they only follow different paths to achieve the same goal.”

Developers thought: “How can I do applications?

Testers thought, “How can I break down applications?”

Testers and Developers operate like Tom and Jerry. But the end result is positive only when both work together.

By saying “How can I break the application” it does not mean that the motto of a Testers is to ruin the work done by the Developers. It means that Testers who think outside the framework and put themselves in the customer’s position, apply all possible scenarios to the application.

For any Developers software applications, the SDLC software development cycle plays an important role. Previously, software testing was done at the final stage of development. But fixing errors / errors at the final stage is very difficult and expensive.

Therefore, to avoid such hassles, now, software testing is part of all stages of SDLC. This means starting Test from the first stage of the process

“Testers” looks at an application from a different creative perspective and if end-user requirements are clear, it makes a lot of difference. View of Testers and Developer at different stages of SDLC:

1) Collect requirements and analyze:

In this stage at the request of the customer and the application will have a required document prepared.

Let’s take a very common example: The end-user request is “Don’t allow special characters to be entered into fields”.

Role Developers: write a code to insert an input field so that when the user enters any special characters, and the appropriate error message is displayed.

The Tester: Tester perspective will first check the requirements, then there will be many scenarios in the head. There will be questions like:

• What happens if only special characters are entered? Will it show the same message or a different message to the user?
• What if the user copied and pasted the combination of special characters and alphanumeric characters into that field?

To evaluate any product or application, Testers must ask questions about a product to cover most scenarios because an end user can be anyone and can use the app in any way. Whichever they want.

2) System / application design:

After collecting the data and after completing the requirements, the Developers begin their design on the application. This includes review of design documents before implementation.

Testers from their understanding and creative thinking analyze all possible situations for all new features, integrated, updated interface .., whatever is mentioned in the request .

They created Test cases, checklist and test data for the application.

3) Implementation stage:

During this stage, Developers actually implement the complete system design.

From Developers’ perspective, they are focusing on building the required functions and the function will work perfectly and efficiently.

From the perspective of Testers, when Developers focus on implementing functions, Testers applies all of their creations to test functionality. It may also be a case when Developers misunderstand the request. And in that case when Testers apply their script and the possibility of that function failing is very high.

4) Check the system:

The Developers upload the application with a view that: the functions implemented by Developers were perfect according to the specified requirements; They show the Testers to verify again.

But for Testers, create a lot of different ways that an end-user can think of using a specific application. It is the task of Testers to use creative thinking and explore every good scenario.

5) Maintenance phase:

This stage is to test the combined efforts of Testers and Developers. The final application after all implementation is sent to users for use. If it works as expected then there is no problem. But if there is any wrong, it requires a combined effort of both Testers and Developers during the maintenance phase.

Testers and Developers together make an effective team because it is the responsibility of both to ensure the best product. This is achieved if both hands work in hand with the right understanding and get positive feedback.

Here are some important points defining the role of Testers and Developers:

• While Developers must ensure that there are no errors in what they develop, Testers should make sure that if there are errors, they should be reported and fixed at the right time.
• One Developer should have positive and constructive feedback from testers.
• It is imperative to say that Developers are ‘experts’ in a separate technical area and they can use all their skills and techniques to develop a project on demand. Testers are third parties that report errors effectively on the basis that the quality of the application can be significantly improved.

Working as a Tester:

“Tester” is a person who is not affected by the application developed by Developers and tester in their own opinion based on practical experience, practice, using applications with all possible situations.

A good Tester is a user who detects many errors while using a new product. Users learn how to use a new product by trying and seeing what happens rather than reading instructions.

Therefore, the main focus of Tester is “What may be wrong.” Developers’ main interest is to provide the required project.

A good Tester and a good Developers:

A good Tester is a person who is comfortable with conflict. Many times it becomes very difficult to identify the source of the errors, it may be an encryption error, document error, design error … But that’s the job of the Tester to report all errors.

A good Developers is one who has positive and constructive feedback, diagnose problems, and debugs it. But Developers often avoid conflicts and interfere.

Conclusion:

Testers and Developers together make an effective team because it is the responsibility of both to ensure the best product. This is achieved if both hands work in hand with the right understanding and get positive feedback from each other.
