"""fuse_gmock_files.py v0.1.0.
|
|
|
|
Fuses Google Mock and Google Test source code into two .h files and a .cc file.
|
|
|
|
SYNOPSIS
|
|
fuse_gmock_files.py [GMOCK_ROOT_DIR] OUTPUT_DIR
|
|
|
|
Scans GMOCK_ROOT_DIR for Google Mock and Google Test source
|
|
code, assuming Google Test is in the GMOCK_ROOT_DIR/../googletest
|
|
directory, and generates three files:
|
|
OUTPUT_DIR/gtest/gtest.h, OUTPUT_DIR/gmock/gmock.h, and
|
|
OUTPUT_DIR/gmock-gtest-all.cc. Then you can build your tests
|
|
by adding OUTPUT_DIR to the include search path and linking
|
|
with OUTPUT_DIR/gmock-gtest-all.cc. These three files contain
|
|
everything you need to use Google Mock. Hence you can
|
|
"install" Google Mock by copying them to wherever you want.
|
|
|
|
GMOCK_ROOT_DIR can be omitted and defaults to the parent
|
|
directory of the directory holding this script.
|
|
|
|
EXAMPLES
|
|
./fuse_gmock_files.py fused_gmock
|
|
./fuse_gmock_files.py path/to/unpacked/gmock fused_gmock
|
|
|
|
This tool is experimental. In particular, it assumes that there is no
|
|
conditional inclusion of Google Mock or Google Test headers. Please
|
|
report any problems to googlemock@googlegroups.com. You can read
|
|
https://github.com/google/googletest/blob/master/docs/gmock_cook_book.md
|
|
for more
|
|
information.
