Hi,
TL;TR. How would be best to distinguish in Groovy 3 foo.x and
foo.getProperty("x") in a call (at the level of an interceptor for a
mocking system)?
More detailed version.
Working on the Spock adjustment to Groovy 3 I spotted that Groovy 3
started for a property access go.x (go - some GroovyObject instance with
a field "x") to call go.getProperty("x") instead of go.getX() directly
(as it took place in Groovy 2). This broke tests for mocking with a
property call (getX() is stubbed, but go.x is called) and forced me to
detect getProperty("x") calls in a mock interceptor - to analyze deeper
and check which method (here getter) is being called and if has been
stubbed.
However, in addition, it should be possible to just stub direct
go.getProperty("x") calls [1]. To do that, currently, I have to analyze
a stack trace to detect groovy.lang.GroovyObject$getProperty.call() at
the position -3 [2] (for direct go.getProperty("x") calls) and deeper
process only the other calls (go.x). It seems to work, but it's quite
ugly and fragile. I wonder, how to reliably differentiate those two
types of calls?
