Question

The Java library that I’m currently working on can be configured with a .properties file in the classpath. Now I want to write JUnit tests that do the following:

1. If the file exists, assert that the values in there are loaded.
2. If the file does not exit, assert that the default values are loaded.

Is that sort of thing possible?

Answer 1

Yes it is possible. Create a temporary .properties file in a folder that is on your classpath for testing. Run test.

In second test rename the file to something else, run test, rename file back to original name.
