Hi Laurent,
Perhaps I am missing something but you only need 2 conditions to detect what
you are looking for:
1) changed method is a test (and defined in a subclass of TestCase)
2) changed method has a sender that is a test method

Hi,
I struggle for a functionality I want to add on Autotest. Suppose a class with
two methods A and B, such as A senders of B
Zork>>methodA self methodB
And unit tests:
ZorkTest>>testSomething ..... Zork new methodA ... self assert: ....
If I change methodA, Autotest detects it, search all senders of methodA in
tests and run. As ZorkTest>>testSomething is sender of Zork>>methodA, it will
find and run it.
Now if I change methodB and there's no senders in tests, the previous heuristic
won't work. So I added as last heuristic: if no method found, search all
TestCases that references the changed method class and run.
So here it will find ZorkTest and run all its tests. The problem is that I
don't really know if the method I've changed has been actually "hit" by the
tests. I just see that tests has been run. I don't know if my method has been
called when running the tests.
So I want to detect this.
One way of doing this seems to use
MethodContext>>runSimulated:contextAtEachStep:. I've found this looking at
MessageTally. Is it the best solution ?
So in Autotest>>findRunAndShowTestsOf: I try something like this
Autotest>>findRunAndShowTestsOf:changedMethod | testMethods aTestResult
methodHit |
"Finds the test related to changedMethod, run them and tell the view to
update" testMethods := search methodsFor: changedMethod.
methodHit := false. thisContext sender
runSimulated: [aTestResult := runner run: testMethods]
contextAtEachStep: [:current|
(current method =
changedMethod) "<--- here I detect if changedMethod has been hit"
ifTrue: [methodHit := true]].
.....
but using this debugger opens with "SimulationGuardException: triggered by
BlockClosure>>newProcess" in MethodContext>>doPrimitive:method:receiver:args:
As I don't (yet :) understand all this stuff, I want to know if it's the right
way to do it and what should I check.
ThanksLaurent Laffont
