What is Test Case in Software Testing? | Features, Benefits

This blog post is about the topic "what is test case in software testing" and its benefits in the development world. The question is seen trending on search engines and needs to be addressed.

What Is Test Case in Software Testing?

A test case is a single-purpose document that tells how to reproduce an issue, including what steps you will take, who will execute them, and when they will be performed. A failure in your test case should result in an error message being displayed on your computer screen or phone screen (if applicable).

A test case is an automated and detailed test script. Test cases are used to recreate a specific problem. They're written in a way that can be understood by a human reader and can also be read by computers, who will then execute the tests on their own. Test cases should be comprehensive, but they shouldn't be overly complex or time-consuming to create. Test cases should be detailed and contain all the necessary information to recreate a specific problem. You must cover every aspect of your software so that there's no question as to what went wrong in any given scenario.

When you're writing test cases, they must be easy to read and understand. You want your readers (that is, whoever is reading your tests) to be able to follow what's going on in them. If a test case can be confusing or difficult for someone else to understand, then it will likely cause problems later on when trying to run the tests themselves. This is why we recommend taking care with how you structure your tests: by crafting them carefully, you can ensure that even someone unfamiliar with Java programming language can easily follow along with what's happening in each scenario. Since we talked a bit about the question of what is test case in software testing, now let’s head on to its direct advantages.

Advantages of Test Cases:

  • A high-level description of functionality being tested - this helps ensure that all individuals involved in building software understand what they need to do;
  • Detailed instructions on how each part of functionality will be tested - this ensures that all individuals involved in building software follow these instructions exactly;
  • Explanations about why certain things were not included/not tested (for example, if there was no time available for testing).

Features of Test Case:

  • Write a test case based on what you already know.
  • Use as much documentation as possible.
  • Write a test case that is easy to understand and repeat.
  • Write a test case that is easy to update when new information or resources become available (e.g., if someone changes the resolution of your app).

Format of Test Cases:

  • Test case id
  • Unit to test: (What to be verified?)
  • Assumptions are taken for the test
  • Test data: (Variables along with their values)
  • Execution Steps
  • Results (expected)
  • Actual results data
  • Did it Pass or Failed
  • End Remarks and Comments

Importance of Test Cases

Test cases are the basis of your testing process. They're made up of scenarios, input values, and expected outputs. Test cases describe how to perform a user story in a system under test (SUT).

A good tester should be able to create test cases for each step required for testing an application or software product by using specific scenarios, inputs, and expected outcomes. This will help you write code faster because you don't have to think about what kind of data should be used while writing your tests as well as what different types of data look like before running them through the SUTs or software products themselves.

Test cases can be used to verify the software in the context of the system under test (SUT). A test case is a set of conditions that must be met for a specific behavior or result, such as an expected outcome or error message. It specifies how this behavior should occur and what inputs should cause it, along with any other relevant information needed by programmers or testers.[1] Test suites are collections of test cases that represent different aspects of an application under development. WeTest testing services of App Test Solution consider every possible test case scenario developer might have and is tested by an experienced team of more than ten years with big names like Riot games, SuperCell, PUBG, and more. WeTest uses leading tech and state-of-the-art techniques with multiple testing tools to consider every possible test case.

Wrapping Up:

This concludes our topic of “what is test case in software testing” and its direct advantages. They are a way to document requirements, the functionality of your system, and bugs in your system. They also allow you to write tests that can be run against any version of your codebase to verify that it is still working as expected. If you've been working with test automation tools for a while, you probably know that writing test cases is not easy. It's quite difficult, and it takes time to get used to the process. However, if there is one thing, we can say about writing test cases is that practice makes perfect!
