sorry for my bad explanation, i try to explain with an example. I have a
method that writes information to disk. This method throws IOException
if cannot write information to disk (disk is full, ...). So if i have a
class called SaveInformation with a method saveInformation, that uses a
class called IOUtils that has a method writeDisk, i would have something
like:
void saveInformation(...) {
try{
IOUtils.writeDisk(....);
catch(IOEXception e) {
e.printStackTrace();
}
}
If i want a 100% of code coverage i need that writeDisk throws a
IOException, of course i could think that for example create a directory
without permissions, but this would be bad because every testing machine
would need this directory. For this reason if i could create a
ProbeInsertion that simply when someone called writeDisk, the probe
insertion fragment throws new IOEXception(), a 100% of code coverage
would reach, and the tester would not to create extra resources like
directories.
Thank you very much.

I don't quite understand why you want to do this. Can you explain
what you mean by : "So i can simulate all IOExceptions without having

Unfortunately fragments can't throw an exception. The Java method
generated for them don't specify this in their header and you can't
modify the generated Java class yourself. It'll just get overwritten
by the Probekit editor. I might be able to help you out if you
further explain the logic behind what you're doing.

[tptp-tracing-profiling-tools-dev] And more things about exceptions
in Probe Insertion
Hello, i think that everybody has noted that i m betting seriously in
TPTP and Probe Insertion. Ok, the problem now is that i want to simulate
an IOException using probeinsertion. My injected code is as simple as
if(methodname.equals("method")) {
throw new IOException();
}
So i can simulate all IOExceptions without having to think in real files
that would throw this kind of exception. The problem is that the method
_entry doesn't throw any exception so it is impossible to simulate
because the exception isn't propagated. Only adding throws Throwable to
this method, this problem would be required. But if i added manually,
then when i try probekit eclipse editor, an error occurs, and all the
information is deleted. Is there any way to throw specific expcetions in
fragment code? With runtime exception would be great, but for example
IOException extends from Exception.
Thank you very much for your attention.
