10.42. DD 42: Wallet Dev Experiments#
10.42.1. Summary#
This design document defines new taler:// URIs to cause synthetic errors
or special states in the wallet that can then be rendered by the UI.
10.42.2. Motivation#
UIs need to handle various (error-) states and responses of wallet-core. It’s not easy to cover all of these states and responses manually. Some of them are hard to reach or simulate without an elaborate test setup.
10.42.3. Requirements#
The implementation of synthetic errors should be as separate from production code as possible, to avoid making the normal code paths unreadable.
10.42.4. Proposed Solution#
10.42.4.1. Special taler:// URIs#
taler://dev-experiment/$STATE_IDtaler://pay/...?dev-experiment=
10.42.4.2. Special http(s):// URIs#
http(s)://*.dev-experiment.taler.net/URLs for this subdomain are handled specially by the wallet’s HTTP layer and return fixed / mocked responses instead of making real requests.
