What is Software Testing? Applying AI in software testing

Software Testing is one of the important stages of the software development process. Software Testing includes many different levels and aims to improve software quality as well as enhance user experi...

Automated testing is often applied when:

Large number of tests, high frequency, large data, and must be performed in a short time.
The test applies in many different environments.
The project is stable, its functions will not change in the future.
Automated testing is iterative over and over again with basic data.

Test Automation is the best way to test and increase the efficiency, test coverage, and speed of execution of software tests. The automated testing process is quite important for many reasons such as:

Test automation helps synchronize workflows, thereby saving time and money.
It is difficult to test multilingual websites without using automation.
Test automation does not require human intervention and can run entirely on its own.
Automated testing helps increase the speed and scope of testing.
Test automation helps the monitoring process become more accurate and clearer.

3. Benefits and limitations of test automation

About benefits:

Automated testing tools are more stable than humans, so the reliability of test automation is higher.
Reduce QA processing time by up to 80%, helping reduce software launch time.
Automated testing helps save costs, improve software accuracy, and ensure information consistency.
Human intervention is not required while conducting the test.
Can be checked regularly.
Processes can be repeated thanks to automation.
Test results through automation are reliable because the process is already in place.
The test can be reused across different versions of the software if there are feature updates or interface changes.

Testing and Debugging: The Important Difference

Nowadays, any software technology company pursues the goal of providing the best service to customers by developing Web App and Mobile App. In the software development process, Testing and Debugging a...

About the disadvantages:

Labor costs, hiring QA engineers, and specialized automated software tool costs are high.
The time to design a software test for the first time is quite long and needs to be carefully installed before testing.
Maintaining and upgrading tests as required takes a lot of time and effort.
Requires Testers to have experience and extremely professional programming skills.

The test automation process includes 5 stages as follows:

Phase 1: Select testing tools

To choose the right testing tool, technicians need to rely on the technology on which the software being tested is built. Each type of testing tool will have its characteristics and is suitable for different types of automated testing. Before deciding on the right tool, you can consider several issues such as:

How many languages does the tool support?
Is the tool easy to develop and maintain scripts?
Is the test reporting function installed?
How many types of testing can the tool be applied to?
Can the tool work on platforms such as websites, smartphones, and tablets?

Phase 2: Determine the scope of automation

Automation coverage is the area where the software under test will have its workflow automated.

To determine the scope of automation, pay attention to the following points:

Typical characteristics of the enterprise.
Complexity of test cases.
Technical feasibility.
General features of the software.
The amount of data of the tested software.

Automation technology is a phrase that is mentioned a lot in the field of industry, production, and distribution of goods today. Automation was born to help enterprises optimize production processes,...

Phase 3: Planning, design and development

At this stage, the technician will plan the test, design, and develop the process. To perform this step, it is necessary to complete the automation tool selection, design the framework and features, and set up the testing schedule and execution time.

Phase 4: Conduct testing

After planning, designing, and developing the test procedure, the test is conducted. Command sets require input test data before being set up to run. After implementation, a detailed test report is required.

The process can be done using automation tools directly or indirectly through test management tools.

Phase 5: System maintenance

Finally, after testing, the software will be maintained and rechecked to see if the software’s functions operate stably or not. The maintenance process takes place regularly and is integrated into command sets to help increase working efficiency and improve the effectiveness of automation commands in subsequent cycles.
