In this thesis, the applicability of the control application of the test automation system as a browser-based software is investigated. The current control application in the target company is a locally installed software on the control computer. The target company wants to renew the current test automation system, which creates the need to find out if the control application can be implemented as a browser-based solution.

The target company is a Finnish industrial equipment manufacturer. The suitability assessment was carried out in the testing and reliability unit of the target company.

The work introduces the target company's reliability testing and test automation system. Software models are studied, and the data transfer protocol used in the suitability assessment is discussed.

As a result of the suitability assessment, it can be stated that a browser-based control application is a possible future solution in the target company to replace the current locally installed software. However, there is still a need for further development and new studies, because the solution produced in the suitability assessment does not meet the requirements of the target company's final product.

The material of this engineering work and the solution created in the feasibility study will be used in the design of the target company's new automation system and in future follow-up studies. The target company was satisfied with the result.
