Writing test scripts for software

Remember: the name of the test method must include the method or unit under test and what is the expected outcome. It should also be noted that each unit should be tested in isolation. A meaningful method name allows anyone reviewing the results to understand what the unit test was testing for. Moreover, it signals the data to be tested, the expected result, and what was tested. If the test fails, knowing the expected result is critical in allowing for easier troubleshooting and ensuring no regressions are introduced.

The data used needs to be enough to execute the test. For unit testing, we want to make it as simple as possible to test the most basic unit of our application. The data could be as simple as making a string or object variable for which you can control the data.

Or a mock framework can be used for the test if a dependency is not available or you need that dependency to be in a specific state. Having just enough to test that one part if sufficient. All of this affects how the unit test will behave since this is the data being used for unit test execution. As such, this part of unit testing is the most time consuming as it requires some understanding of the code you are testing to know what data to use for testing.

Keep it simple by using just the parts needed for the code being tested. Mocks are very useful in this phase as they allow you to control how methods from those objects will behave when interacting with your test.

We do not want to introduce nor configure another object for this test as it adds another layer of maintainability for that object, and it is not affecting the result of the method under test.

The next line shows the Account object being created along with the mock and the Initial Balance to prepare the method we are testing for with the data we just used. The next line defines the input as the method under test requires a number to be used.

Then the method is executed with the result of the method being stored in our variable for us to use later. Once the test can complete successfully as in it runs from start to finish with no exceptions or errors , then it is time to apply an assertion to the unit test.

Without the assertion, the unit test is meaningless since there is nothing you are enforcing to ensure it is working as intended. Collecting coverage of what lines were executed does tell what was executed but it does not provide enough detail to determine the following:.

As long as the unit test contains one assertion that is checking the method under test result, this is a meaningful unit test. How to write effective tests and test cases can be streamlined over time. Some best practices include using strong titles, strong descriptions, and keeping the language concise and clear. The other aspect of a test case involves test suites and test plans. These differ in key ways and both are vital to accurate test case development.

A test suite comes into play for test cases as it relates to source code, the collection of dependencies, or the suite of tests to be performed on code. Test suites allow you to categorize test cases in ways that align with any analysis or planning needs. This means that core software features might have their own test suite while another test suite is for a specific testing type such as smoke or security.

Think of test suites as a bookshelf to organize your test cases on. In contrast, a test plan is more like the umbrella that stands over all of the test suites. If test cases are books and test suites are bookshelves, then test plans are the room that contains the bookshelf. Generally, test plans are set up in terms of manual tests, automated tests, and a general format of how to go about testing. Not only can they assist with automation, but they can help from the very beginning of development.

One might forget that software just has to function first. This tool allows beginners and experts alike to improve their unit testing skills more quickly, as well as the unit testing experience. After establishing a foundation, it executes the unit tests then guides the user to ensure that the tests are meaningful.

When you can understand the kinds of things to look for in a test, test case writing becomes less intimidating. As a Solution Architect at Parasoft, William helps teams strategize and prioritize as they adopt modern software development and testing practices into their organization. Reading Time: 10 minutes How to write test cases might not seem like such an important part of development. In this blog, we cover the following topics related to how to write a test case: What is a test case?

Test script vs. Request a Demo. Download Whitepaper. Read the Blog. Simplify API testing and boost software quality. This makes sure that each function is tested correctly and that testers do not miss steps in the software testing process. You should be creative enough to predict all the different paths that users would use while running a system or application. Test Script Template is a reusable formatted document that contains pre-selected information important for creating a usable test script.

This document determines how detailed your tests are and what information should be included in each test case. Skip to content.
