However, these testing principles can also be acquired through experience. But why not gain all this knowledge before making any blunders?
Come let’s dive into them!
Optimal Software Testing Practices
Here are a few of the Leading Testing Practices that can be garnered from Experience:
#1) Learn to Scrutinize your test results in detail. Do not disregard any test results. The final test result may be a “pass” or a “fail”, but investigating the root cause of a “fail” will deliver the solution to the issue. Testers will be esteemed if they not only log the Bugs but also propose remedies.
#2) Make efforts to augment Test Coverage each time you test any software. Achieving 100% test coverage might not be feasible but regardless, one can always aim to attain near to it.
#3) To guarantee maximum test coverage, devise your Application Under Test (AUT) into more compact functional units. Create test cases for each of these individual unit modules. Also, break these modules into even smaller components if feasible.
For instance, let’s hypothesize that you’ve subdivided your web application into modules and ‘taking user information’ is one of them. This ‘User information’ screen can be disintegrated into smaller pieces for establishing test cases: Segments like UI testing, Security Testing, Functional Testing of the ‘User information’ form etc.
Execute all kinds of field types and size tests, negative and validation tests in the input fields, and form all such test cases for maximum coverage.
#4) When Constructing Test Cases, initially write test scenarios for intended function i.e., valid scenarios according to the specifications. Followed by writing test cases for invalid scenarios. This will encompass the predicted as well as unforeseen behavior of the application at hand.
#5) Cultivate a positive mindset. Start testing the program with the objective of finding glitches/errors. Don’t preconceive that the application will be bug-free. If you examine the application with the intention of spotting bugs, you will definitely manage to uncover those Subtle Bugs too.
#6) Formulate your test cases during the requirement analysis and design phase itself. This way you can ensure all the requirements are testable.
#7) Make your test cases available to the developers before coding starts. Don’t withhold your test cases waiting for the final application release for testing, thinking that you can log more bugs. Allow the developers to thoroughly examine your test cases to build a quality application. This will also spare re-work time.
#8) If possible, identify and categorize your test cases for Regression Testing. This facilitates quick and effective manual Regression Testing.
#9) For applications critical in response time, they should be exhaustively tested for performance. Performance testing is an indispensable part of several applications. In Manual Testing, it is often neglected by testers due to a lack of required large data volume.
Seek ways to test your application for performance. If it’s not viable to generate test data manually, then generate some basic scripts to create performance test data or ask the developers to write one for you.
#10) Developers should not test their own code. As mentioned in our previous post, mere Unit Testing of developed applications should suffice for developers to release the application to testers. But you (testing personnel) should not pressurize the developers to release the product for testing.
Let them take their own time. Everyone at all levels, from the lead to the manager, is well-aware of when the module/update will be released for testing and they can estimate the testing period accordingly. This process is standard in an Agile project scenario.
#11) Go beyond the scope of Requirement Testing. Examine the application for what it is not expected to do.
#12) During regression testing, make use of the prior Bug graph (Bug graph – count of bugs discovered over time for various modules). This module-based bug chart can be invaluable to predict the most likely defective part of the application.
#13) Record any new terms and techniques you encounter while testing. Keep a text file open during the testing of applications. Jot down the testing progress and observations in it. Employ these notepad annotations while preparing the final test release report. This good practice will assist you in producing a comprehensive unambiguous test report and release particulars.
#14) Often testers or developers alter the code base of the application under testing. This is a necessary step during development or testing to prevent the execution of live transactions like in banking projects.
Jot down all such testing related code changes and ensure to remove all these alterations from the final client-side deployment file sources at the time of final release.
#15) Maintain a distance between developers and the test environment. This practice is required to identify any missing configuration changes in the release or deployment document. Occasionally developers make system or application configuration changes but fail to include these in the deployment steps.
If developers do not have access to the testing environment, they cannot make such changes accidentally on it and the omitted elements can be detected at the proper place.
#16) A good approach is to involve testers from the Requirement and Design phase itself.
This way, testers can gain an understanding of application relationships leading to more detailed test coverage. If you are not asked to be a part of the development cycle, you should ask your superior or manager to involve your testing team in all decision-making processes and meetings.
#17) Testing teams should share their best testing practices and experiences with the other teams in their organization.
#18) Enhance your conversation with developers to understand more about the product. Whenever possible, have face-to-face interactions to resolve disputes quickly and prevent any misunderstandings.
But also, when you comprehend the requirements or resolve any disagreement, ensure to communicate the same through written communication methods like emails. Do not keep anything verbal.
#19) Don’t run out of time to perform high-priority testing activities. Organize your testing work in order of high to low priority and structure your work accordingly. Evaluate all associated risks to prioritize your work.
#20) Write a lucid, detailed, and unambiguous Bug Report. Do not merely present the bug symptoms but also provide the impact of the bug and all possible solutions.
Remember, testing is a creative and challenging task. Ultimately, your skill and experience determine how successfully you meet this challenge.
