Automated testing is processes that run programs and scripts to test individual modules using repetitive actions. In fact, this means that the program runs certain scripts to check all the components of the project and evaluate it. In order to create any testing tools, certain resources are required. Automated testing should include a tester who will create the program and then run it. The most popular testing software is Selenium.
Not that long ago testing of programs was carried out manually either by the programmers themselves or by users, which could hardly be called a systematic approach and, moreover, did not allow evaluating the quality of the code. A little later, testing stood out in a separate area of knowledge as part of software development and rather quickly came the realization that manual testing is inefficient since it requires a lot of workforce and time. The first test automation tools were mainly libraries that could be used to write test scripts, which required the tester to be able to program at the developer level. Modern automated testing tools allow you to create automated tests with minimal human involvement.
What is Automation Testing Pyramid?
Automation testing is closely linked to Mike Cohn as he introduced the automation testing system in the form of a pyramid.
The base of the pyramid is Unit Tests, the process of checking individual modules of the source code. Unit tests are good at testing code that contains some kind of logic. If there is little logic in the code, and it mostly refers to other classes then unit tests can be difficult to write.
The second stage is Integration Tests – at this stage, individual software modules are tested in groups. In order to avoid errors and not depend on external conditions, integration testing is carried out in a controlled environment.
After that goes Acceptance Testing, which determines the suitability of the product for future use.
At the top of the pyramid, is UI Tests, which can be carried out both automatically and manually. Thus, automated testing is at the junction of testing and programming.
Manual testing in the form of a cloud is often placed above the peak since it is not considered an integral part of the pyramid, although it is interconnected with it. This pyramid is considered typical for test automation, although it can be turned upside down and modified depending on the specifics of the work.
What types of testing are recommended to be automated?
Regression Testing. This type of testing is the first candidate for automation due to the regular launch of tests. On long-term projects, automation technology can significantly reduce the cost of ensuring product quality.
Stress Testing. Automation of stress testing allows you to get results faster, save on capacities and cost of tools.
Localization Testing. If the product will be introduced to the world market, it must be adapted to the cultural aspects of different countries. Localization includes the translation of all interface elements, service elements, adaptation of the display mode of the date, time, units, currency. Even more, if the product is regularly updated and new functionality is added, then it is more profitable to conduct localization testing in an automatic mode.
Automated testing. Main nuances of software quality control
Modern software is a complex multifunctional object. Its manual verification requires significant workforce and time costs. That is why automation testing tools come to rescue as they improve the quality and provide reuse of tests when adjusting the software. The test automation process is the intellectual creativity of highly qualified IT specialists. However, to achieve desired goals it also needs to be carried out systematically. At each stage, specialists choose the right test strategy when checking the quality of the investigated object. The use of automation software testing tools is relevant in the following cases:
- Writing to the database, file logging, backend processes, that is, places in the system that are difficult to access.
- Quite often it is used functionality that has a high level of risk for errors. Automating critical functionality through testing ensures errors to be found quickly.
- Automated testing is effective for routine operations. For example, forms in which there are a large number of fields for a data set. The test process allows you to automatically fill in the fields, as well as to check them after saving.
- This type of testing allows you to automate the process of filling in the fields with incorrect data, to test various validations.
- Long scenarios (end-to-end).
- Testing data that requires accurate mathematical calculations.
- To automate the correctness of data search.
Depending on the requirements of the company and the capabilities of the tool, other software products are also subject of automation testing. The development of separate automation test cases makes the testing process more efficient. Creating initial conditions minimally affecting other tests allows you to use test scripts that can return the system to its original state.
What are test automation areas?
Evaluating the functionality of the application GUI. Automated GUI testing allows you to emulate the work of real users with the system interface. At the same time, the operation of the system is checked for compliance with the technical specifications using modern automated testing tools. Automated GUI testing is designed to test the application through the graphical user interface. Any applications that have a graphical user interface need to be tested by the GUI, including web applications, client desktop applications, banking applications, payment systems.
What are the key benefits of GUI testing?
- Imitation of the work of real users of the system using automated test scripts.
- Testing numerous application scenarios, including those that are difficult to test manually.
- Checking the correct operation of the application on large volumes of test data without a significant increase in labor costs.
Evaluating database compliance with functional and non-functional requirements. Database testing allows you to verify the correct functioning of the database and minimize risks when implementing the system in commercial operation. Database testing allows you to check the operation of the database application for compliance with functional and non-functional requirements. Any applications that include databases in their architecture require database testing, including web applications, applications with a high degree of criticality for business, applications with high fault tolerance, banking applications.
What are the key benefits of database testing?
- Checking the logic of the application implemented at the database level, including stored procedures, tables, and views, relationships between tables, indexes, scheduled tasks, access rights for users.
- Data warehouse fault tolerance check.
- Identification of application performance problems on large volumes of test data.
Web Service Testing
Testing the functionality of web services implemented by automated testing tools. Quite often, web services are used as an intermediary between the client part of the application and the data provider. A web service can have several consumer systems, so the availability of many other client business decisions depends on the reliability of its operation. The service allows you to identify possible defects in the operation of the web service and check its implementation for compliance with industry standards.
What are the key benefits of web service testing?
- Identification of defects in the integration of automated customer systems, the interaction of which is carried out using web services.
- Checking numerous scenarios of web services without the need to deploy additional customer systems (consumers and suppliers).
Automation testing of mobile applications
Checking the functionality of a mobile application on various mobile devices and operating systems. Test automation is not a new topic, but mobile automation has become a relatively recent trend. And the demand for the service is constantly growing. This is due to the fact that mobile applications are becoming more functional, taking over the role of desktop PCs. However, the growing functionality and frequent updates do not always allow the manual tester to cover all regression cases in a short period of time. And here automation, as well as automation software, come to the rescue.
What are the key benefits of mobile applications testing?
- The advantages of automated testing of mobile applications coincide in many respects with the advantages of automated testing of web applications.
- Decrease in terms of testing a mobile application.
- Improving the quality of testing by testing numerous application scenarios on a variety of devices and platforms.
- Leveling problems associated with a manual approach to testing (decreased attentiveness when performing similar tests).
Checking the efficiency of web application modules. Testing web applications is a complex process consisting of many interdependent elements and requiring a professional approach. A team of experienced experts performs a full analysis of the system in order to identify existing defects and problems and also provides control over the completeness of their correction at further stages of development. In the process of checking the application, specialists take into account the specifics of a particular project and the mechanics of the interaction of the server-side, web servers, database, user interface, and third-party components.
What are the key benefits of website testing?
- Website testing can improve the layout to display relevant information on it.
- It can help you get rid of all the ineffective elements on your site, including bad links, ads, buttons, text, code, etc. that distract your message.
- It also lowers the cost of development and changes the design, enhancing user satisfaction.
- Identifies important tasks to be accomplished in the design process.
- The best-performing pages on your site will emulate their strengths over the weakest ones.
- You get an extra level of website testing in areas that haven't been tested yet, or for more detailed testing.
- Productivity increases and cost decreases.
