> It is called defensive programming
In any case, if you want to be extremely defensive (I do not see reasons for
this specific case), you can have try-catch:
```diff
@@ -77,7 +77,14 @@ public class Version {
// Because we expect the properties file to be in the same
directory/package
// as this class, the relative path comes in handy and as a bonus is
also
// relocation-friendly (think Maven Shade).
- return Version.class.getResourceAsStream("version.properties");
+ try {
+ return Version.class.getResourceAsStream("version.properties");
+ } catch(Exception e) {
+ new IllegalStateException("Unable to find Xalan's version.properties
resource", e)
+ .printStackTrace();
+ // It must not happen, however, we keep it just in case
+ return null;
+ }
}
```
Frankly, I do not see why one would have that (we should trust
`Class.getResourceAsStream` to a degree), however, adding try-catch there does
not break the code, it fulfills all your requests, it yields the same backward
compatibility, the same test coverage, and it yields better error messages as I
can have separate messages to clarify the error condition (e.g. unable to parse
resource vs unable to find the resource in the first place)
At least, I truly do not see why you said `Not true`. Of course, the very
same tests could be written without Mockito with exactly same efforts.
