"""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/gtest |
|
sub-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 |
|
http://code.google.com/p/googlemock/wiki/CookBook for more |
|
information. |
