I am native English, but can grasp enough German to at least find the ausgang. bitte!
I want to explore what our app does when I change between a few supported languages, on Windows, Mac and “linux”, are there any get out of jail free cards or tips/hotkeys/pointers that will help me verify that basic things switch over when I start my app after changing my locale. Ways to safely change locale? There must be so many newbie mistakes to make or not. I have gotten some hints from a thread a year ago here Website Localisation Testing, Where Did You Start? . But am keen not to necro that thread, because my context is more about exploring and not actually bugs, and is definitely not about text layout and CSS/web apps yet. Not going as far as buying different keyboards, but valuable guidance here welcome too. Asian languages are not currently on the cards, but please do weight in if you have experience in that department and things like right-to-left etc.
It’s a separate thing entirely to test localization, and my scope is just smoke-testing depth, like opening a few dialogues and relying on memory and learning just enough of a language, to check that forms have roughly the correct kind of data in them only.
