Tester’s and Developer’s Mindsets

Tram Ho

Testers and developers (Tester and Dev) often have different thoughts. Usually, a Dev guy often thinks: How can I create applications? The Tester’s Perspective, as well as the User’s Perspective, is: How can I break the application? But we can only achieve the desired result when both dev and test handshake.

In this article, we will discuss the different views of Dev and Test and how they can work together to achieve efficiency and success.

Mindset of Dev and Tester

Thinking is the way we handle situations, the ways we deal with what is happening and what we should do. Different people around us have different mindsets. Similarly, devs and testers have a different way of thinking. Usually the dev will ask: What do I need to build, what should I do? The tester will ask: What could be wrong? What can I do to break the application or find a weak spot?

By saying, ‘How can I break the application? It does not mean that the motto of Tester is to ruin the work done by the dev. That means the Tester should put itself in the customer’s shoes and test the application for all possible scenarios and ensure that the application is not broken when in a production environment.

Opinions of devs and testers at different stages of the Software Development Life Cycle (SDLC):

Software development life cycle (SDLC) plays a very important role in any software application development. Previously, software testing happened during the final development stage. However, fixing the errors in the final stage is often very difficult and expensive. Therefore software testing currently occurs at every stage of SDLC. It means that testing starts right at the request stage. Both testers and developers have become an integral part of the development process from the beginning.

Let us discuss and get a brief idea of ​​the involvement of testers and developers at different stages of SDLC:

  1. Request collection and analysis: The preparation of required documents takes place during this phase, as stated by the customer.
  • Dev’s role: After receiving the request documents, they will analyze the requirements and start researching the technology.
  • The role of the Tester: After analyzing the requirements document, the testing team can ask more about the requirements. Tester can also find required defect. It saves time and money if discovered and fixed at this stage.
  1. System design: During this phase, the structure, interface, modules and data for a system are defined to meet the specified requirements.
  • Dev role: The conversion of requirements defined in the requirements analysis phase into the system design document takes place here. This document accurately describes the system design. In addition, it acts as an input for the development of the system in the next phase. Based on these detailed specifications, developers write code for the software.
  • The role of Tester: From testers, from their understanding and creative thinking, analyzing all possible scenarios for all new, integrated features … Preparing scenarios Trial version & test data occurs to ensure smooth application testing. For this, they create a test strategy, integrated test plan, test case, test list and test data.
  1. Coding phase: The coding phase is also called the implementation or development phase. It involves the development of real products. The dev writes the code and then tests it continuously and incrementally to make sure that different components work together. This is the most time-consuming stage of the SDLC process.
  • Dev’s role: After the system design phase is over, the next stage is coding. During this phase, developers begin to build the entire system by writing code in the chosen programming language. During the coding phase, the division of a task into units or modules takes place and then, it is assigned to each dev.
  • Tester role: During this stage, the function test will be performed. The tester will test as soon as the dev completes coding for each module. At this stage, the tester will test each component and also conduct component integration testing. Therefore, Tester needs to work closely with devs to make this phase successful.
  1. Testing the system: After the software is completed and deployed in a test environment, the Tester team starts testing the functionality of the entire system. That is to ensure that the entire application works according to customer requirements.
  • Dev’s role: Tester finds bugs and feedback for developers. Dev receives ticket bugs and checks again as well as fixes and sends it back to the Tester team to check again. This process continues until the software has no errors, is stable and works, and conforms to the Requirement
  • Tester’s Role: During this phase, the Tester performs test cases from start to finish and verifies every aspect of the system. In addition to the desired functionality, they also test the system from a user perspective. So these Tester use their creative thinking and explore each possible scenario. Testing of system integration, including integration with third-party systems, also occurred at this stage.
  1. Maintenance phase: The maintenance phase begins when the system deployment process comes into production and the customer begins using the product. This phase includes post-deployment support and fixes.
  • Dev’s role: During this phase, the developer performs the following three activities: – Bug fixes: The developer fixes bugs reported by the customer. – Update: They update the application to the latest versions of the software. – Improvement: The developer also added some new features to existing software based on customer feedback.
  • Tester role: When the dev completes its work, the tester retry the application. Tester ensures that the system works correctly after code changes or advanced functions. The tester is also responsible for performing regression testing to ensure the existing functionality is not broken by the latest changes.

Therefore, we find that developers and testers interact a lot during each stage of the software development life cycle. Therefore, they must work together as a single team to ensure a successful project.

Compare the Test Mindsets and Dev

Creating software products is a complex endeavor that requires the cooperation of people with different skills, knowledge and thinking. Developers and testers must work together to create and deliver quality products. These people may have different perspectives, perceptions and insights. To understand the differences in their approach and perspective, let’s consider the following points-

  • Compare dev and test approaches: Testing and reviewing other applications with their analysis and development. Dev, while creating or developing applications, is working hard to create products according to user specifications; Continually solve problems during development. However, during testing or reviewing a product, Tester will often find defects and bugs in the product. Therefore, building software requires a different mindset to test the software.
  • Dev plays the role of Tester: Although, Dev and Tester are two separate roles; That doesn’t mean their roles are irreversible. In other words, Tester can be dev and vice versa. Developers always check the component they build before giving it to anyone. This process is called Unit Test. However, we all know that it’s hard to find your own mistakes. Therefore, dev sends applications for testing, experts or professional testers to allow independent testing of the system. This level of independence avoids the bias of the creator itself and is often more effective at finding defects and bugs.
  • Communication about defects between dev and test: It is the responsibility of the tester to test the software according to the specified requirements and report errors. But app builders can react conservatively and treat this reported flaw as a personal judgment. Therefore, Tester needs to be very careful when acting or reporting bugs / errors to the dev to avoid unnecessary conflicts.

In short, appreciating the difference is essential for production groups. But different approaches help find a solution and lead to providing a product that works in the best way. Tester and dev together form a capable group. Their responsibility is to ensure the best product. And, it is only possible if the two of them shake hands with proper understanding and positive feedback.
