The term ‘automation’ means the absence or minimal impact of human factors on the testing process. The main purpose of automation is to increase testing effectiveness and to cover the most user scenarios within the same limited period of time, and thus, to improve the software.
Usually, automated testing is combined with manual testing. This way, it becomes a powerful tool for project development and testing.
Because automation is not set in stone and it is not a must-have in software development, the question is when to automate testing.
What projects do require automation testing?
There are several preconditions when to automate testing on a project with maximum benefits. Basically, test automation best practices make possible to minimize human errors on repetitive tasks when engineers get easily distracted.
From our experience, automation is needed in the following cases:
- Highly complex projects – i.e. when functional testing is impossible through manual testing.
- Projects with ongoing changes – when adding new functionality into existing projects/updating existing functions, i.e. when doing regression testing.
- Portability testing (or configuration testing) – when software development targets several platforms.
When deciding on automated testing, customers should be aware that the initial cost of the development and implementation of test scripts is higher than for manual testing. Moreover, every quality assurance (QA) team member must possess programming skills as well as experience in automation. Automation tools are chosen according to the automation level, which should be determined for any specific project since functional, regression, user interface (UI), and load testing may be automated.
Why is automation testing important?
Automation testing services help increase the quality of the end product, and also improve the product’s structure and the mobility of the used test scripts. Instead of spending their time on what has been done already, QA engineers can focus on top priorities, such as security testing, functional, and performance testing and more.
Here are the benefits of automation testing:
impact on testing
100% guarantee that all required testing will be conducted within the specified time limits
save time during regression testing
every time a new feature is released, QAs must check its compatibility with already existing code;
automated tests do it better
save time for stabilization
testers use automated tests to quickly check the functionality before they forward the app for manual testing
automated testing makes it possible to do tests with more accuracy and on a larger scale
Automation implies that testers prepare a test script once and then use it during the whole development process; they make changes only to adopt it to the changes in requirements.
What are the main types of automation testing?
Many of testing activities on a project can be automated; however, the degree of test automation depends on the project requirements.
The most frequently automated test types include:
What Test Cases Cannot Be Automated?
Automated testing does not work well for small-scaled, simple projects with rare updates.
This is why: automation is a laborious, time-consuming process which requires a full range of technical documentation from automation testing company (which describes all details of the particular process including specifications for developers and a test plan for the testing team), experience, and clear objectives.
Owners may just exceed their budget which they can spend on other, more important things. Instead of enjoying benefits of automation testing—those become visible within a relatively large scope of work—they may just get things they will not really use.
Hence, the need of automation testing must be discussed with experts in order to apply the right strategy for software development.
