java - Junit test; Is it possible to configure a Bean's default property, before application context starts up? -

i have bean property "dbserver"; has default of "location1";

during application startup, depending on value of "dbserver", different classes instantiated.

i have 200 tests default setting fine.

however, of now,i test alternative.

question:

is there way within junit test case reset default before application context starts ?

junit won't start application context unless write setup method under @before annotation. in case can initialize bean values.
