How to Create Test Cases?

A TEST CASE is a series of activities performed to ensure that a specific feature or functionality of your software application is working properly. A Test Case is a set of test steps, data, preconditions, and postconditions created for a particular test scenario in order to validate any requirement. The test case contains complex variables or conditions that a testing engineer may use to compare predicted and actual outcomes in order to assess if a software product meets the customer’s needs.

In order to decide whether a function of an application is working correctly, a test case has elements that define input, behavior, and expected response.

1. A well-written test case must enable any tester to comprehend and perform the test.

When writing test cases, it’s important to understand the type of the user and provide all relevant information. Spending the extra time and effort upfront to write successful test cases will save you time and effort later. The difference between a well-tested application and a badly tested application can be determined by well-written test cases. Effective testing necessitates the development of simple and functional test cases. This technique ensures the consistency and therefore the performance of your product, so you can’t afford to take risks and make them at a chance.

Writing test cases, particularly large numbers of them at once, can take a long time. TestDel makes it easy to write and arrange high-quality test cases. We’ve included some pointers on how to write test cases below this.

2. Tips for Writing Test Cases Safely

2.1. Use a Catchy Headline

A strong headline is the foundation of a successful test case. It’s a good idea to call the test case after the module that you’re testing as a best practice. If you’re checking the login page, for example, include “Login Page” in the test case description. If the tool you’re using doesn’t already do this, it might make sense to include a unique identifier in the headline of the test case as well, so that the identifier can be mentioned rather than a long title.

2.2. Test Cases must be Straightforward and Easy to Understand

Make the test cases as clear as possible. They must be straightforward and descriptive since the test case writer might not be able to implement them. Use declarative language such as “go to the home page,” “enter the info,” “click here,” and so on. This makes it easier to grasp the test steps and speeds up the testing process.

2.3. Self-Contained

They are unable to rely on other test cases. Your test is unreliable if it needs many more test cases to be performed until it can be maintained. If you need to add any preconditions, do so during the setup of the test case to prevent any constraints. However, be wary of too many prescriptions in this situation. As a result of this autonomy, test cases can be run in random order. In the case of automation, this can also determine if they can be applied in tandem.

2.4. Ensure Complete Coverage

Make sure you write test cases to ensure you’ve covered all of the program specifications in the requirement specification. To ensure that no use case or scenarios are left untested, use the traceability matrix .

2.5. Definite

In order to get conclusive results and prevent “ambiguity,” test designers should specifically state the success or failure requirements for each test case.

2.6. Recognizable

The test case id should be named in such a way that it can be easily found and recognized later on when monitoring defects or recognizing a program requirement.

2.7. Use Testing Methodologies

In the software application, you won’t be able to search for any possible scenario. Software testing methods assist you in selecting a small number of test cases that have the best chance of detecting a flaw.

Boundary Value Analysis (BVA): As the name implies, this technique defines the testing of boundaries for a given range of values.
Equivalence Partitioning (EP): This technique divides the range into equal parts/groups that have similar behavior
State Transition Technique: This method is used when the behavior of software changes from one state to another as a result of a specific activity.
Error Guessing Technique: This is a method for guessing/predicting errors that may occur during manual testing. This is not a traditional procedure, but it makes use of a tester’s prior experience with the application.

2.8. Concentrated on a single task.

Just one item or one element should be measured in a single test case. Assume it tests two things at the same time and one of them fails. Is the test case going to pass or fail? Someone could say, ‘partially.’ However, this is not the expected outcome of testers. Tests must be precise and free of confusion.

2.9. Repeatable and Reusable

Some test cases will almost always need to be repeated, so make sure you built your test case in such a way that it can be re-executed at any time, either immediately or after some time has passed.

A good test case is reusable and significantly contributes to the software testing team in the longer term. Take this into consideration when writing a test case. You will save time in the long run by reusing the test case rather than writing it from scratch.

2.10. Interpersonal Assessment.

After you’ve finished creating test cases, have them reviewed by your coworkers. Your teammates can spot flaws in your test case design that you might overlook.

These were some of the tips or pointers which you can look for while writing an effective test case.
