These are slow tests that we were already effectively turning into
no-ops when running on Travis CI. By skipping them using the proper
JUnit mechanism, these tests will show up as ignored or skipped in
test outcome reports. That's better than having them show up as
passing, when we really don't know whether they would have passed or
failed.
Unnecessary "throws" declarations tend to cascade. If foo() calls
bar() and bar() falsely declares that it might throw IOException, that
often leads a programmer to declare that foo() might throw IOException
as well. Fixing the bar() throws declaration then reveals that we can
fix the foo() throws declaration too. By the time we reach a fixed
point with cleaning these up, we have removed roughly 320 unnecessary
throws declarations.
In a few cases, this cleanup even lets us remove entire "try
... catch" statements where the only thing being caught was an
exception that we now statically know cannot be thrown. Nice!
In Eclipse project configurations, upgrade any future such shenanigans
from warnings to errors. Now that we've fixed this, we don't want it
coming back again.
There is a potential drawback to this change. Conceivably some public
WALA API entry point might have declared that it could throw some
exception merely to reserve the *option* of throwing that exception in
third-party code that subclasses and overrides the API entry point in
question. I have no idea whether this is a significant concern in
practice, though.
We used to use junit.framework.Assert for test assertions, and that
class reports failures by throwing
junit.framework.AssertionFailedError. However, junit.framework.Assert
is obsoleted by org.junit.Assert, and we've already replaced the
former with the latter. org.junit.Assert reports failures by throwing
java.lang.AssertionError, so that's what we need to expect in our
testing infrastructure.
now, for me, code works using e44 with maven
dalvik tests refactored for mobile version with android dev tools
IDE tests Eclipse metadata fixed to make e44 work for me
new android entrypoint to fix failure in new droidbench tests
