What Types of Test Cases Need to Be Automated?

Testing is one of the essential steps in creating software because it helps to identify the slightest problems in the software. Today there are 2 main types of testing – automatic and manual. Each of them has a different scope and performs other functions. Today we want to focus on automated tests and determine when their use is mandatory.

What is automated testing and its role in software operation?

Automated testing uses various tools that help to analyze the program code more deeply. A person sets a test script, and the tool checks the software’s operation. Over the past few years, automated testing has taken an enormous step forward, allowing you to detect the most minor previously inaccessible bugs.

Automation testing services are typically used after the code has been written, and the application or site has gone live. It allows you to run tests invisibly to users, which helps you identify and fix bugs before they become visible to users or lead to system failures.

Test cases to automate first

Before you start automating, you should develop a testing strategy. It is worth introducing automation gradually, which will avoid possible errors and make the process more thoughtful and efficient. We have identified 3 testing cases that need to be automated first.

1. Unit testing

Any software consists of several modules, each responsible for specific functions. Test automation is best to start with unit testing because this is the easiest way. Here you create reusable tests that are easy to set up and do not require significant financial costs. Today, there are a large number of frameworks that you can use when debugging unit testing, no matter what programming language you use.

2. Integration tests

Integration tests allow you to understand how well your software works with other programs and operating systems. You expect your site to work equally well across different browsers and devices. Doing manual testing will take a lot of time, and you need access to many devices. But, when using automatic testing, you can check the operation of your software as quickly as possible and ensure a high-quality connection.

3. Functional testing

Your software will only be successful if it performs the functions for which it was created. The main task of functional testing is to check whether your software can perform the most important goals and tasks. To perform functional testing, you can use simple tools and a lot of time to set them up.

Which aspects of software operation should be automated, and which should be left to manual tests?

Many experts say automated testing may completely replace manual testing in the next few years. Indeed, this allows you to study the program code and highlight hidden vulnerabilities. However, a few aspects should be left to manual tests, such as checking the operation of the interface. Unfortunately, today automated tests cannot simulate human behavior. So, only people can evaluate how convenient it is to use your device.

At the same time, most tests need to be automated. All technical aspects of your software should be entrusted to special tools. They can identify performance or security issues and evaluate compatibility with various devices or payment systems.

What problems can you face when automating testing?

Even though automation has a vast number of advantages, in the early stages, you will have to face specific difficulties:

1. Selection of test instruments. When choosing tools, there are many factors to consider, such as the programming language, features, and test cases that need to be executed.
2. Financial costs. Most of the tools are paid, so you need to spend a lot of money on them.
3. Creation of documentation. When testing is complete, the tools will list the bugs they found. The tester’s task is to analyze them and recommend their elimination. All changes to the software must be documented.
4. Interaction in the team. It is essential to establish communication within your teams. Programmers must understand the importance of testing and respond to errors in time.
5. Test service. Sometimes people think it is enough to write a test script once, but the truth is that the approach to testing should be flexible and change as the project and market situation grows.

But the main problem is choosing the most suitable testers. Experienced professionals know the above difficulties and can cope with them. The QA team should be well versed in the peculiarities of your project and do everything possible to identify and correct errors in time. They should have the necessary experience with similar projects and the skills to use the right tools.
