Disadvantages of Tosca

 Some of the cons of using Tosca include:

• High cost: Like UFT, Tosca is a commercial tool and can be expensive for small organizations or projects. It’s perhaps not as expensive as UFT, but it’s a licensing cost that companies will still need to be willing to pay.
• Maintenance: Its base scripting might be easy to set up, but if you’re not writing your own frameworks, reliant on the core modules, maintenance could be quite a challenge.
• Big footprint: Its VM footprint for its automation runners remains quite sizeable and not ideal for widespread containerization or cloud usage.
• Performance: While the tool is no slouch, it's one of the slower automation tools when it comes to object scanning and so its execution speeds are not ideal for regular pipeline execution.

When to select Tosca:

• If you need your automation to cover a wide range of application types while still supporting traditional open-source tools.
• If accessibility testing is critical to you, Tosca has one of the best offers in this range
• When you have the budget for a big integrated testing suite but are wary of long-term vendor lock.
