What A Software Testers Do?

Software Testers

Software testers are responsible for checking that software applications are functional, reliable, and meet the user’s needs. They use various techniques, such as manual testing, automation testing, or performance testing, to identify defects and improve software quality. Another essential attribution of a tester is to provide constructive feedback, so that it can improve the quality of the software they test.

A software testing role also involves working in collaboration with multiple stakeholders including developers, project support teams and system users to understand the scope of the project. A software tester troubleshoots, writes bug reports, provides feedback to developers, and also communicates test outcomes with both technical and non-technical stakeholders.

Software testers often analyses how the application should work before the code is even written. They ask questions like “what if the user does this” or “what if I enter a negative value? What happens?” These are just two examples of questions. They can multiply infinitely. The software tester’s job is to anticipate as many potential scenarios for using the application as possible. Eliminating bugs at the very beginning of our development process is cheaper than fixing them at a later stage.

testers pay attention to the fact that the navigation should be intuitive and not misleading. Often at this point, the tester’s job also involves making suggestions for improvements to the app. Then, after the developers have created the app, the software testers proceed to test it. At this point, the tester’s job is to verify that the ordered app works according to the requirements. The tester has to make sure that the system does exactly what it is supposed to do and that it works fast enough to fulfil its function. Additionally, it has to be checked if the app is intuitive, easy to use and its visual part is good in perception.

If you’re someone who enjoys a challenge and solving complex problems, a career in software testing might be just the thing for you. Each new software is different and poses different issues. This requires looking at products from different angles and adopting a new approach to testing each time.

Goals Of A Software Test

The goals of software testing are multifaceted and critical to the overall success of software development. Testing is not just about finding bugs, it encompasses a broader scope aimed at ensuring the software meets its requirements and provides a quality user experience.

1. Verify and Validate

  • Verification: Ensures the product is developed correctly according to the design specifications.
  • Validation: Ensures the product meets the user’s needs and requirements.

2. Ensure Quality

The primary goal of testing is to ensure the software’s quality. This includes its usability, reliability, performance, and security. Quality software not only meets its functional requirements but also provides a satisfactory user experience.

3. Detect Defects

Identifying bugs and defects before the software reaches the end user is a core objective. This process involves executing the software under controlled conditions and checking if it behaves as expected. Finding defects early in the development cycle can significantly reduce the cost and time to fix them.

4. Reduce Risks

Testing helps to mitigate risks associated with software failure. By identifying potential issues early, testing can prevent bugs that might cause data loss, security breaches, or system outages, thereby reducing the risk of financial loss and damage to the brand’s reputation.

5. Compliance with Requirements

Ensuring that the software complies with regulatory standards and industry specific requirements is essential, especially for applications in areas like healthcare, finance, and aviation. Compliance helps in avoiding legal penalties and ensuring the software is safe and reliable.

6. Support Decision Making

Testing provides stakeholders with information about the software’s quality and risks associated with its deployment. This information is crucial for making informed decisions regarding the software’s release readiness and understanding any limitations it may have.

7. Enhance User Satisfaction

By ensuring the software is bug free, easy to use, and performs well under various conditions, testing aims to enhance overall user satisfaction. Satisfied users are more likely to trust and remain loyal to the software.

8. Facilitate Continuous Improvement

The feedback loop from testing into the development process allows teams to continuously improve the software. Testing can uncover areas of improvement not only in the application itself but also in the development and testing processes.

9. Support Product Evolution

As software evolves with new features and updates, testing ensures that modifications do not adversely affect the existing functionality. Regression testing, for example, checks that new code changes do not introduce new defects into existing features.

Types of software testing

There are many types of software testing, but the two main categories are dynamic testing and static testing.
Dynamic testing is an assessment that’s conducted while the program is executed; static testing examines the program’s code and associated documentation. Dynamic and static methods are often used together.

The Main Types Of Software Testing Methodologies:

  • Integration testing. This groups together two or more modules of an application to ensure they function collectively. This type of testing also reveals interface, communication and data flow defects between modules.
  • Unit testing. Typically conducted during the application development phase, the purpose of unit testing is to ensure that each individual unit or component performs as expected. This is a type of white box testing and test automation tools.
  • Functional testing. This entails checking functions against functional requirements. A common way to conduct functional testing is by using the black box testing
  • Security testing. This ensures the software is free of potential vulnerabilities, known flaws and security loopholes that might affect the user system and data. Security testing is generally conducted through penetration testing.
  • Performance testing. This tests the performance and speed of an application under a given workload.
  • Regression testing. This verifies whether adding new features causes a decline in the functionality of an application.
  • Stress testing. This assesses the strength of software by testing how much load it can take before reaching a breaking point. This is a type of nonfunctional test.
  • Acceptance testing. This evaluates the entire system against the desired requirements and ensures the project is complete.

Software Tester Duties

  • analyzing users’ stories and/or use cases/requirements for validity and feasibility
  • collaborate closely with other team members and departments
  • execute all levels of testing (System, Integration, and Regression)
  • Design and develop automation scripts when needed
  • Detect and track software defects and inconsistencies
  • Provide timely solutions
  • Apply quality engineering principles throughout the Agile product lifecycle
  • Provide support and documentation


Software testers play a critical role in the development lifecycle, ensuring the reliability, functionality, and quality of software products. Identify bugs and inconsistencies, assess the software’s performance, and validate that it meets all requirements and specifications.
Beyond just finding errors, testers contribute to improving user experience, enhancing security, and ensuring the software behaves as expected under various conditions.
