Automated testing presupposes using automation tools to execute a set of test cases. As this kind of work is done by automatic, less time is required for manual testing, but more time is needed to support automated scenarios. Automation is good for large projects that require multiple checks of the same areas. Also those projects that have already passed the initial process of manual testing. Finding bugs in simple operations is the main task of automation. This type of testing is more suitable for large-scale companies, as it requires significant investments.
Advantages of the automated testing
Automation has many advantages, some of which will be discussed below:
- round-the-clock tests are an opportunity to start the test in the evening and get the results in the morning after coming to work;
- fewer specialists – preferably one automation engineer, instead of a group of manual testers;
- sequence – an opportunity to learn about previously performed actions;
- volume – the number of devices on which tests are carried out can be simply huge;
- reuse is the most reliable way, because no test can be missed;
- execution without intervention while the tests are being executed, the tester can do other useful things.
Thanks to these advantages, it can be argued that the quality of the obtained product will be high. Less time and resources are spent on testing.
The most popular programming languages for automated testing
The programming language used in automation also plays an important role. There are eight main points to consider when evaluating any automation language. These criteria specifically evaluate the language in terms of cleanliness and usability, not necessarily in terms of the immediate needs of the project.
Usability. A good automation language is quite high-level and should perform complex tasks such as memory management. Development speed is also very important to project timelines.
Elegance. The process of translating a test case into code should be simple and clear. For ease of maintenance, test code should also be kept short and self-documenting.
Available Test Frameworks. Frameworks provide basic needs such as setup/cleanup, logging and reporting. Examples are Cucumber and xUnit.
Available Packages. It is better to use ready-made packages for common operations, such as web drivers (Selenium), HTTP requests and SSH.
Powerful Command Line. A good CLI makes it easy to run tests. This is very important for continuous integration when tests cannot be run manually.
Easy Build Integration. Build automation should run tests and report results. Complex integration is a nightmare for developers.
IDE Support. Because Notepad and vim are simply not suitable for large projects.
Industry Adoption. Support is important. If the language remains popular, the frameworks and packages will be well supported.
Next, we will consider the most popular languages for test automation.
