These informal test cases occur when the tester evaluates the system on an ad-hoc basis to attempt to discover defects missed by structured testing. Test cases define how to test a system, software or an application. A test case is a singular set of actions or instructions for a tester to perform that validates a specific aspect of a product or application functionality. If the test fails, the result might be a software defect that the organization can triage.

Test cases also confirm whether the product meets its software requirements. This test confirms recent code or program changes have not affected existing system features. Regression testing involves selecting all or some of the executed test cases and running them again to confirm the software’s existing functionalities still perform appropriately.

The tester must understand the application flows well to write effective integration tests. A test case provides a set of actions performed to verify that specific software features are performing correctly. Test cases are typically written by members of the quality assurance team or the testing team and can be used as step-by-step instructions for each system test. Testing begins once the development team has finished a system feature or set of features. A sequence or collection of test cases is called a test suite.

Any conditions that are necessary for the tester or QA engineer to perform the test. Higher quality products lead to more satisfied customers. The above fields give context for the test that is going to be performed. The information remains available to anyone who wants to see who performed the test and what exactly was done.

Formal and Informal Test Case

As part of the quality assurance process, they are designing test cases to evaluate and validate the performance of their app. Next, testers should define how the software testing activities are performed. This process starts by identifying effective test case scenarios — or functionality that can be tested.

  • Test cases are typically written by members of the quality assurance team or the testing team and can be used as step-by-step instructions for each system test.
  • Check if the user is logged in successfully by verifying the presence of the home screen.
  • Organizations can conduct usability testing in a variety of ways, including moderated or unmoderated and remote or in-person.
  • Knowing what a test case is, will improve your documentation, specifications, and code by making them testable and easier to read and understand.
  • Here are the inputs and results from a simple test.

Writing test case ensures the maximum coverage of the product or application as per the customer requirement. It saves time of the team members as no one has to sit and make another person understand about the functionality of the feature. With Applause augmenting your internal testing efforts, your organization can focus on high-priority quality initiatives and ensure your customers have top-notch digital experiences.

Software Testing Metrics

A Metric defines in quantitative terms the degree to which a system, system component, or process possesses a given attribute. The ideal example to understand metrics would be a weekly mileage of a car compared to its ideal mileage recommended by the manufacturer. Larger test cases may also contain prerequisite states or steps, and descriptions. Test steps – In this field, the exact steps are mentioned for performing the test case.

On the other hand, the test case status will likely be marked as fail if the actual results do not match the expected results. After running an important test case, she discovers that the actual result and the expected result are not the same. A test case can have one or multiple test scripts and a collection of test cases is called a test suite. In scenario testing, hypothetical stories are used to help the tester think through a complex problem or system. These scenarios are usually not written down in any detail. They can be as simple as a diagram for a testing environment or they could be a description written in prose.

The test has failed here as the page was not loaded due to a browser compatibility issue, it would have loaded the test would have passed. Here a test case template for login functionality has been created with its parameters and values. So, test cases are written in such cases, as test cases help in further development and make sure that we are meeting all the needed requirements.

Test cases require consistency in naming conventions and descriptions. A sanity check can also reveal whether the writer’s “simple” description of the test steps actually makes sense to another reader, and that it reflects real-world conditions. Generally, the tester should write test cases early in the SDLC, such as during the requirements gathering phase. Testers should refer to requirements and use case documentation as well as the overall test plan when they write test cases. A prototype can also inform the tester about how the feature or functionality will look when completed.

Negative tests ensure the system handles invalid input correctly, such as not allowing login if a password is wrong. Both types of tests either pass or fail depending on the expected outcome. These types of test cases assess how the combined functionality works when merged into the application. While it is important to test individual units of software, it is equally important to make sure disparate systems can communicate with each other effectively.

Software Testing Metrics: What is, Types & Example

Verify that a successful login is indicated by viewing the home screen for the app, which should now display an active user session. Test Case should be marked as Blocked in case any feature is not functional at all. Moreover for Incomplete or Impeded completely depends on the story/business requirement. Your clients will not wait for your systems to react to finish the purchase. Test cases help to check if a particular module/software is meeting the specified requirement or not. To understand how to calculate the test metrics, we will see an example of a percentage test case executed.

Test case steps should be broken into the smallest possible segments to avoid confusion when executing. Reusable, meaning the document can be reused to successfully perform the test again in the future. Economical, meaning no unnecessary steps or words are used. An outline of how the system should respond to each test step. Also called the description, this important component describes what the test intends to verify in one to two sentences. Now let’s see some examples from Daniel’s application that tracks traffic and suggests the best route.

Testing Traffic

A good test case will include information about how the test was performed, what results were expected and what results were obtained. That information can be useful when performing later tests or when building or troubleshooting future versions. If the test status comes up as ”Passed,” the team can be assured that the product performed the function as expected with the given inputs. Eventually, the team can release a tested, error-free program. The overall importance of different test cases is often divided into three categories known as high, low, and medium.

Types of Behavior Driven Development (BDD)

This component identifies what the test case needs to run correctly, such as app version, operation system, date and time requirements and security specifications. Links to user stories, design specifications or requirements that the test is expected to verify. definition of blocked test case Daniel is a software engineer who has created a new application to track traffic for drivers and suggest the best route. He wants to make sure that the software works properly, so he asks for advice from his friend Rocky, who is a software tester.

When the actual result and the expected results are the same, it means that the software is working as expected and the test status is pass. When the expected result and the actual result are not the same, the status of the project is fail, meaning some changes to the software or application need to be incorporated before testing it again. The overall goal of test cases is to improve the quality and accuracy of software and applications before they are released to users. Software Testing Metrics are the quantitative measures used to estimate the progress, quality, productivity and health of the software testing process.


These types of test cases validate the product from the end user’s perspective. An end user or client conducts user acceptance tests in a testing environment to validate the end-to-end flow of the product. Organizations can conduct usability testing in a variety of ways, including moderated or unmoderated and remote or in-person. The goal is to take advantage of an end user’s perspective to identify points in the application that would cause them to stop using it.

This is the output you actually receive from the system. Part of a QA organization’s success depends on test case management. Learn the challenges that software dev orgs face in managing TCM and see three best practices. To establish the right development team size, managers must look at each member’s responsibilities and communication paths, as … In 2023, companies expect to increase spending on public cloud applications and infrastructure, and hyperscalers that have …

With these types of test cases, the tester writes a test in which the inputs are all known and detailed, such as the preconditions and test data. Formal tests have predefined input, which means they provide an expected output, which the test attempts to validate. A test script is a line-by-line description of all the actions and data needed to properly perform a test. The script includes detailed explanations of the steps needed to achieve a specific goal within the program, as well as descriptions of the results that are expected for each step. An integration test case is written to determine how the different software modules interact with each other.

An expected result or expected outcome is usually given. For applications or systems without formal requirements, test cases can be written based on the accepted normal operation of programs of a similar class. In some schools of testing, test cases are not written at all but the activities and results are reported after the tests have been run.

Testers execute these types of test cases to discover and record the outcomes, which can reveal interesting findings about digital quality. This type of test case aims to examine what is happening internally, helping testers understand where the data is going in the system. Testing teams frequently use SQL queries to write database test cases. The next step is to define the test case framework. Test cases typically analyze compatibility, functionality, fault tolerance, user interface and the performance of different elements.
