Join Chiu-Ki Chan for an in-depth discussion in this video Incoming intents: Loading string, part of Advanced Android Espresso Testing.
- [Instructor] Let's take a look at the…Punny Test Method.…On line 30 we had coded the string Punny.…In general, it is better to load strings from…resources instead of hot coding it.…That way when we update a string resource…the test automatically looks for the updated string.…To load a string resource we need a context.…Let's add that.…
In the beginning of the test method on line 29 add…val context…= InstrumentationRegistry….getTargetContext…Make sure you pick getTargetContext…instead of getContext.…What is the difference?…getContext gives you the context of the test APK…which does not contain the strings in the app.…
For that you need getTargetContext.…Now that we have a context…we can load the string with context.getString…On line 31…type val theme…= context….getString…and then R.string.theme_punny…Next, replace the hot coded strings with this theme.…
On line 34 for the second parameter…replace the hot coded string Punny with theme.…Do the same on line 38.…Let's run the test to make sure it still passes.…Click on the green triangle.…
