The importance of software testing is often overlooked. It's not enough to write code that works; it needs to work for everyone else.
And this can't be done without tester input. Testing has a responsibility in making sure a product will work for all customers and their different needs, wants, and limitations.
Software testers are the last line of defense before releasing new features or updates into production or live environments. If they find problems with what has been built, they have saved countless hours of frustration from being experienced by users once these issues are released live to the public.
Here are seven things everyone should know to understand what is software testing.
Testing Is Not a Phase; It's a Process
Software testing is not a phase that someone goes through; it's a process that should be integrated into a development cycle. The earlier someone starts testing, the easier and less expensive it will be to find and fix errors.
There is no such thing as perfect code, so there will always be room for improvement. Testers should be included in the design and development to get the most accurate picture of how it will work once released.
Tests Can Be Automated
Not all tests need to be done manually. Automated testing tools can help speed up the process by automating repeated tasks. This also helps to ensure accuracy and consistency. In addition, automated tests can be run on different platforms and configurations, ensuring that the product works as expected no matter where it's used or who's using it.
Code Cannot Be Tested in Isolation
Code cannot be tested in isolation because the owner doesn't know how their product will integrate with all of the other products that may be running. Everything is connected and should be tested to ensure everything works as expected when integrated into a larger system or suite of applications. When someone asks what end-to-end testing is, this is the answer.
Integrated Tests Are Better Than Unit Tests
It might seem more efficient to separate each component and write unit tests when writing test cases, but this is not how most automated tools work best. Integrated tests provide the most accurate results because they consider how different components affect each other when working together in the same environment. As a result, they can find errors that would go unnoticed if written in isolation.
Testing Is an Art
There is no right or wrong way to test software. What works for one product may not work for another. However, testers must have a good understanding of how the software works and what can go wrong. They must also be creative in finding ways to break the software so they can find potential problems.
Testers Are Friends
Testers are not the enemy. Instead, they are the last line of defense against releasing a broken product. Testers should be included in the development process to provide feedback early and often. This will help avoid misunderstandings and ensure that the final product is ready for production.
Testing Affects Everyone
If testing finds a problem, no one can release that particular feature or update until it's fixed. This affects the entire development team and may set back other progress. However, if a test case does not find an issue, everyone can move on to working on what's next instead of wasting time going through the old code again.
Software testing is not easy because it's an abstract process that requires critical thinking and creativity. However, many tools and services are available to help automate the process so testers can spend more time focusing on problems instead of spending all day running test cases. Everyone who works for a software company should know about testing.
