"""gen_gtest_pred_impl.py v0.1
|
|
|
|
Generates the implementation of Google Test predicate assertions and
|
|
accompanying tests.
|
|
|
|
Usage:
|
|
|
|
gen_gtest_pred_impl.py MAX_ARITY
|
|
|
|
where MAX_ARITY is a positive integer.
|
|
|
|
The command generates the implementation of up-to MAX_ARITY-ary
|
|
predicate assertions, and writes it to file gtest_pred_impl.h in the
|
|
directory where the script is. It also generates the accompanying
|
|
unit test in file gtest_pred_impl_unittest.cc.
