When people think about Software Testing, they often imagine someone checking an application for bugs after it has been developed. However, a Software Tester’s role involves much more than just finding errors.
Testers analyze requirements, check how different features behave, identify unexpected issues and work closely with developers to improve the quality of the applications before it reaches the end users.
Understanding What The Software Should Do
Before testing an application, the testers need to have knowledge about the application and how it works. They study the requirements and expected behaviour of different features.
For example, while testing an online shopping application, a tester may need to understand how users should search for products, add items to their cart, make payments, and place orders. This helps them compare the actual behaviour of the application with what was expected.
Creating Test Cases
Testers usually create test cases to thoroughly check the features of the application. A test case defines what needs to be tested, the steps to follow, and the expected result.
For instance, for a login page, a tester may check whether a user can log in using correct credentials. They may also check incorrect passwords, empty fields, invalid usernames and other possible scenarios.
Thinking Beyond The Normal Scenario
A good tester does not only check whether a feature works when everything goes as expected. They also think about what could go wrong.
If a website asks the users to enter their mobile numbers, a tester may check what will happen if the field is empty, too many digits are entered, letters are entered or there is a use of special characters.
This requires logical thinking, curiosity, and attention to detail.
Finding & Reporting Bugs
If testers discover unexpected behaviour, they report it to the development team. A good bug report explains what went wrong, the steps to reproduce the issue, the expected result, and the actual result. Screenshots or recordings may also be included when required.
Clear reporting helps developers understand and fix problems more efficiently.
Resting After The Fix
A tester’s job does not end when a developer fixes the bug. They need to reset the issue to ensure that it has been resolved.
They may also check related features to ensure that it has not affected something that was already working properly. This is known as regression testing.
Working With Different Teams
Testers work regularly with developers, business analysts, product managers, designers and other team members. They discuss requirements, give suggestions and feedback, clarify expected behaviour and report issues throughout the development process.
Manual Testing & Automation
Testing can involve both manual and automation testing. Manual testing involves checking applications yourself, while automation uses scripts and tools to perform repetitive tests.
For beginners, understanding testing fundamentals, test cases, bug reporting, SQL, APIs and basic programming can provide a strong foundation.
The Bottom Line
The software testers do much more than find bugs. They understand requirements, test different scenarios, investigate unexpected behaviour, report issues and verify fixes.
For students looking to enter the IT industry, developing logical thinking, attention to detail, communication, and testing skills can provide a strong foundation for a career in software testing.
