Quality assurance in software holds great importance. It ensures the final quality of the product meets the desired requirements. There are different approaches to testing. Though it is not possible to test everything, you can close by choosing the different types of test cases. By enrolling in Quality Assurance Training Chicagoyou can learn about different. The course helps you understand software quality assurance and its various concepts, including choosing the test cases that best suit your requirements for achieving the highest quality product.The chances are that some of these areas might overlap with others; however, each type of software quality assurance testing and category of the test case has a unique purpose. Reading further, you will explore some of the commonly used test cases in the software testing world.

User Interface Test Cases

User Interface Test cases are used for verifying those particular pieces of the GUI – Graphical User Interface – work and look as pre-decided and expected. Such test cases are used for identifying cosmetic inconsistencies, spelling errors and grammar, links, and other elements that the end-users see or interact with.

The testing team generally writes user interface test cases; however, the design team may also be involved because they know the interface. These test cases are usually used in software testing for cross-browser testing. Browsers render things differently, and user interface test cases help ensure your software application works consistently across all the browsers. These test cases are performed once the software development is done and the User Interface is hooked up to the database. For instance, what happens when a website is browsed on a small screen like a smartphone? Does the User Interface break?

Functionality Test Cases

These are widely used for discovering if the application interface works with the remaining system and its users. The tests establish the failure or success of functions that the software app has to perform.

These test cases are a form of black-box testing that uses for its base the user stories or specifications of the software on which the test is performed. This makes it possible to perform testing without having access to the internal structures or working of the software product being tested. As the task belongs to the QA processes, the software quality assurance team is generally the writers of functional test cases. The first function can be written and run as soon as it is available for testing. If the tester has access to the requirements, they can be written in advancement to steer the development process.

Usability Test Cases

Also known as “scenarios” or “tasks,” these test cases have an important role to play in the software Quality Assurance Process. Instead of providing complete step-by-step guidelines to implement the test, the software quality assurance professionals are presented with a high-level task or scenario to complete.

Usability test cases help identify how end-users approach and use the software application. They guide the tester through several flows and situations. In this case, there is no requirement to have prior knowledge of the application. The design team prepares the test cases along with the testing team. It should be performed before user acceptance testing. For instance, can the user add more than one product to the shopping cart?

Performance Test Cases

These test cases validate the overall effectiveness and response time of an app. Once the action is executed, how long does the system take to respond? It is important to ensure that the performance test cases have clear success criteria.

Usually, performance test cases are automated and written by the testing team. A large application can have hundreds, maybe thousands of performance tests. Automating and running these test cases helps understand scenarios or situations in which the application fails to perform at the expected level.

These test cases help software Quality Assurance Professionals understand how the application would perform in the real world. Once the testing team receives performance requirements from the product development team, the test cases can be written effectively. It is equally important to know that several performance issues can be recognized manually without a specific set of requirements. For instance – how long does the system take to load the next page or authenticate a user? Does the software app remain stable when multiple people log in at the same time?

Integration Test Cases

The main purpose of integration test cases is to establish how different modules interact with each other. These test cases make sure that the interfaces between the different types of modules work properly or as intended. The testing team identifies the areas that must undergo integration testing, while the development team determines how those test cases should be written. Either of these two teams might work for writing the integration test cases. They verify that the modules work individually as well as together. For instance, they check the link between the favorite section and the home page. When an item is marked “favorite” from the homepage, does it appear in the “favorite” section?

Database Test Cases

Database test cases examine what happens behind the scenes. The user interface is clean, and everything works smoothly; however, where is the data going? To write these test cases, you should know the stored procedures, the entire application, and the database tables. The software testing team usually uses SQL queries for developing and writing Database test cases. These test cases verify that the developer has written a code in such a way that it handles and stores data safely and consistently. For instance, think of the creation of a user profile. The following should be considered when the user submits their profile according to the database. 

  • Was there any data loss in the process?
  • Unauthorized users should not have access to the user’s information.
  • Did the software app store the inputted data in the database?
  • Partially written data should not have been saved.

These are some of the most commonly used test cases in the software quality assurance process. There is so much more to learn about test cases. The best way to get started is by registering for a short-duration course like quality assurance training in Chicago and learning about different types of test cases.
