The test case is the first and most important step in any software testing cycle, and it is crucial to any software testing project. If something goes wrong at this stage, the impact will be amplified throughout the software testing process. This can be readily avoided if QA engineers and testers follow the correct recommendations and procedures while creating the test case template. But first, let's take a short look at what the Test Case is all about.
What Are Test Cases in Software Testing
It is a key document that contains a set of procedures and conditions that must be followed on the software app in order to confirm the feature's intended performance and usefulness. Test case primarily examines whether a software app or one of its features is performing as expected. The test case is the most important and descriptive method of documenting test work after test scripts.
Test cases guide the enthusiastic software tester through a sequence of actions to confirm whether an app is bug-free and performs as expected by the end-user. Knowing how to write effective test cases necessitates attention to detail, basic writing skills, and a great understanding of the AUT (application under test).
A test suite is a collection of test cases for a certain module or component of an app. There will almost always be multiple test cases in a testing session because there will be more than one situation to be tested. The majority of enterprises use test case management systems such as JIRA, HP QC (HP Quality Center), while others still use excel sheets to write test cases.
Who Writes Test Cases
It varies from one organization to the next. If a dedicated group or team of testers and developers is involved, it might be considered a collaborative effort.
- Testers write Acceptance Tests
- Developers write Unit Tests
- Testers & Developers write Integration Tests
Any quality assurance tester should be able to understand and carry out the test if the test case is well-written. When developing test cases for software testing, it's crucial that they put themselves in the shoes of the customer and consider all relevant information. Investing the extra time and effort now to write good test cases will save them time and work later.
Advantages of Writing Effective Test Cases
The advantages of Writing an effective test case are as below:
- Test cases make sure effective test coverage
- Lessen the software support and maintenance costs
- Help improve the software quality
- Help confirm that the software meets the end-user necessities
- Test cases can be reusable for future deeds– anybody could reference them and carry out the test.
- Allows the software tester to think carefully and approach the testing from distinct angles as possible
How To Write Test Cases in an Effective Way
Some of the most important points on how to write test cases are as follows:
Deep Knowledge of Domain
In IT, detailed domain knowledge requires a thorough understanding of operational dynamics and business, as well as the project's prospects and hazards. The best practices in the given vertical must be followed.
Stay In Your Lane
It is always best to get a thorough understanding and knowledge of the SRS document. Testers often become more intuitive somewhat rather than following a common or logical approach, and often this intuition results in assumptions. When creating test cases, an assumption of functionalities and features might occasionally lead them away from the actual requirements of the user or client. This will have an impact not just on the product being tested, but also on customer-company relationships.
Simple To Understand and Execute Language
We need to use simple language like "enter username," "click on the login button," "go to the login page," "enter a password," and so on to make the test cases clear and faster to perform.
Be Aware of the Product Updates
Concentration on SRS is critical, but not if it is based on an out-of-date version of the software. No one wants to put a depreciated or obsolete trait to the test! We live in a world ruled by agile approaches, in which product development is pushed into the fast lane. The software requirements specification (SRS) document is occasionally left unmodified to deal with shorter time frames or after organizing an urgent bug repair. It is recommended that any minor or substantial modification be documented in the software requirements specification (SRS).
Include the Anticipated Outcome
The expected outcome informs the tester of what they should expect as a result of or as a consequence of the test stages. This is where the software tester decides if the test case is a “fail” or “pass”
100% Test Coverage
Test coverage is a crucial aspect of any software's long-term viability. Before anyone digs deep into the test cases, it's critical to aim for 100 percent test coverage. Make a mental note to cover all of the functionality and components listed in the SRS document with your test cases.
Writing test cases necessitates a thorough understanding of the software under test as well as some practice. Test cases that are well-written can make your testing process go faster, smoother, and save you time and effort in the long run.
