In modern times, the shift left testing approach has taken back all the software engineers. But what does it actually mean? In simple words, it means performing more software testing during the software development process in order to improve quality and reduce the number of defects in an application. Shift-left testing is a popular concept in the QA, where engineers work hard to detect defects as early as possible in the testing process so that it can be moved to development. Mostly, it means that QA testers engage in developing and executing more automated testing of the user interface (UI) and APIs.
However, there are some basic software testing steps that every software developer should perform before showing someone else their work. It is also imperative to use test case management tools whether it is for shift-left testing, Adhoc testing, formal testing, or just getting quick help from a colleague. The main goal is to identify the defects that appear immediately. Elsewise, QA engineers get into an expensive and unnecessary cycle of having to describe the issues to the developer, who then has to reproduce it, debug it, and resolve it before running it again.
Following are a few essential software testing steps that every software engineer should perform prior to sending an application into production:
Test engineers should begin their testing processes by ensuring that the basic functionality of an application works. This means that they should make sure that every button on the screen works. It is also essential to ensure that they can enter simple text into each field without crashing the application. The main aim here is to test the application thoroughly before anyone else can test/use it.
Developers write unit tests to ensure that the unit is working as expected to and test it with a range of valid and invalid inputs. In a continuous testing environment, unit tests should run every time there us a change made to the source code repository. Some teams set goals for their unit tests yet fail a build if the tests aren’t extensive enough.
It is always a good idea to have another peer or colleague having a look at the source code to uncover issues in an application. If a coding methodology requires peer review, this step should be performed before handing the code for testing.
Test Case Management Tools
Introducing test case management tools early in the development process will help engineers keep track of their test cases in an organized manner. It is better to stay hands-on with a tool that integrates with the other tools in a software testing suite to ensure testing is headed in the right direction.
Striking the Right Balance
It can be a little tricky for engineers to maintain the right balance by finding out to test your application before handing it to anyone for retesting or detection of bugs. It is better to identify and resolve issues before someone else can do that for you.
