Test cases are one of the most important part in any project because it is the opening step in any testing cycle. If anything goes wrong at the first step, the impact gets extrapolated as you move forward in the software testing life-cycle.
Knowing how to write a good test case is utterly important for you as a testing resource doesn’t take much intention.
What is a test case? It is a term that implicates the documentation which states input, prerequisites, set of accomplishment steps and expected results. There are elements that describe an input, action or event and a pending reply, to induce if a feature of the app is working rightly.It describes what to test and how to run a particular test. Test case means a detailed procedure that fully tests a feature or an aspect of a feature and it ought to be listed in the test scenario. Test cases are one of the most important part in any project because it is the important part in any testing cycle. Knowing how to write a good test case is utterly important for performing test with a great chance to find errors in the test project.
What is test scenario? It is any functionality that should be tested. Every test scenario is joined to a minimum of Requirements or User Story as per the Project Methodology. Test scenarios based on customer priorities should be run. It guarantees that the Test Coverage will be completed. Test scenario serves as a quick tool to determine the testing work effort and create a proposal accordingly for the client or organize the workforce and allows the customer to optimally allocate time and efforts of test engineers. They help to make the most important end-to-end transactions testing or the actual use case of the software apps. Also, they are used for studying the program functioning.
Importance of the Scenario Testing
All-round testing of any software app is impossible because of the following reasons: the quantity of input data combinations and possible paths in the software tends to infinity.
As a result, you constantly prioritize your testing efforts and focus on the most important areas. It ensures that software works for the most accepted user scenarios. And it helps to find lots of defects which cannot be found with other testing types.
Scenario testing is essential for complex transactions and for considering end-to-end functioning of the program.
Test cases are vital parts of Software Development Life Cycle and it’s difficult to track, penetrate, follow and think out something without one. Scenario testing is done by creating test cases that reproduce the various use cases. A test scenario might be an independent test case or a series of test cases that follow each other. Test case scenario is just a story that explains the usage of the software by any end user.
Let us consider the difference between test scenario and test case.
- The test scenario is no more than test procedure. Test case involves a set of inputs to cover definite test Condition.
- A scenario has umpteen test cases. Test cases must be written for the test scenario. First, you prepare test scenarios then you create test cases for each scenario.
- The test case is derived (or written) from test scenario. And the scenario is derived from the use case.
- Test Scenario means a series of actions that are associated together. While test Case means an action performed by user.
In general, test cases is how one can run a test and the test scenario is what to test.So, what is test case? The following video will provide you with more information about what test case and test scenario are
These are the 10 steps you ought to take in any test case scenario
Step 1. Name your test case thoroughlyA strong title is a good start for a test case.You may call it as the module that is tested or functional area that is verified. E. g. if the login page is tested the title of the test case must include “Login Page”.
Step 2. Write a description for every test case
Reading the description the tester must understand what he is going to test and the purpose of running the test. The description contains pertinent information (test data, precondition, assumption, test environment). Make sure to add as much information as possible before the test case is run.
Step 3. Consider the data
Test data ought to be given for test case or test case step. You must mention the proper data for each test.If the test involves some values that must be verified, you can specify the value range or describe what values must be tested and for which field. It also can be done for negative scenarios.
Step 4. Cover all verification points in test design steps
Ensure that test case optimally covers all the verification points.The test steps should contain the data and information on how to perform the test. This is the most fundamental part of a test case. Keep this section clear and don’t leave out any necessary details.
Step 5. Consider dividing test cases into sets if necessary
You should consider subdividing your Test Cases into sets (subsets) to test some certain scenarios. If you aim for writing an effective test case, you should mention these special functions of the test cases one by one. Ensure that all scenarios (positive and negative) are included. For example, the test case that verifies error conditions should be written apart from functional test case and have steps to verify the error messages.
Step 6. Ensure that it is readable and simply apprehensible
You should keep in mind that the Test Case will not always be carried out by the one who designs it. So the tests should be simply apprehensible, readable and to-the-point.
Step 7. Give some expected resultsExpected results help to determine whether the test is a “pass” or “fail”. So, when writing test cases, note at length what page/screen you contemplate to appear after the test. You should mention updates you expect as a result to be made in back-end systems or database. Screenshots or specification documents can be attached to the relevant step mentioning the system work as outlined in the given document.
Step 8. Make sure about maintenance and updates
It’s of great importance to sure that the Test Case is eternally updated as per the lately introduced changes in the app they apply to. Always consider updating the existing Test Cases before you start writing a new one!
Step 9. Review the test case
After creating test cases must be reviewed. Your peers can uncover missteps in your test case design, that you may simply overlook.
Step 10. Make it reusable
Test cases may be reused in other projects.A good test case is reusable and provides longtime concern to the software testing team. If you need a specific test case to execute another one, you can transfer the existing test case in pre-conditions or at a specific test design step.
As you see, writing an effective test case with all the necessary details on is a very important thing in the test cycle. The test case must be effective at finding defects and implement most of the scenarios on the tested system. If you will follow the steps we have prepared your test cases will really help you in your test process.
