Manage legacy testing application

A legacy software is a software that has been in production for some time. It may have had several successive versions or code refactorings that correctly met the customers needs. The maintenance of this kind of solution can be reduced to a minimum: few evolutions and limited bug fixes. The maintenance can be ensured by a team composed of a part-time single person. This kind of software is "as is" as far as the testing and validation aspects are concerned, and everything is possible: manual tests galore or redundant tests, automated tests on several automation solutions, no data tests, no unit tests...

Legacy software testing is important because older software systems are often critical to business operations and can be difficult to replace or upgrade. Testing helps to identify any potential issues or bugs that may impact the functionality of the software, allowing them to be addressed before they cause problems.

Legacy software testing is often more challenging than testing newer software because the older systems may not have documentation or support resources available. Additionally, the software may have been modified over time by different developers, making it more difficult to understand how it functions.

The frequency of legacy software testing will depend on the specific needs of the software and the business it supports. It is generally recommended to perform testing on a regular basis, such as every six months or annually, to ensure that the software is functioning properly and to identify any potential issues before they cause problems.
