| 32 """fuse_gmock_files.py v0.1.0 | |
| 33 Fuses Google Mock and Google Test source code into two .h files and a .cc file. | |
| 34 | |
| 35 SYNOPSIS | |
| 36 fuse_gmock_files.py [GMOCK_ROOT_DIR] OUTPUT_DIR | |
| 37 | |
| 38 Scans GMOCK_ROOT_DIR for Google Mock and Google Test source | |
| 39 code, assuming Google Test is in the GMOCK_ROOT_DIR/gtest | |
| 40 sub-directory, and generates three files: | |
| 41 OUTPUT_DIR/gtest/gtest.h, OUTPUT_DIR/gmock/gmock.h, and | |
| 42 OUTPUT_DIR/gmock-gtest-all.cc. Then you can build your tests | |
| 43 by adding OUTPUT_DIR to the include search path and linking | |
| 44 with OUTPUT_DIR/gmock-gtest-all.cc. These three files contain | |
| 45 everything you need to use Google Mock. Hence you can | |
| 46 "install" Google Mock by copying them to wherever you want. | |
| 47 | |
| 48 GMOCK_ROOT_DIR can be omitted and defaults to the parent | |
| 49 directory of the directory holding this script. | |
| 50 | |
| 51 EXAMPLES | |
| 52 ./fuse_gmock_files.py fused_gmock | |
| 53 ./fuse_gmock_files.py path/to/unpacked/gmock fused_gmock | |
| 54 | |
| 55 This tool is experimental. In particular, it assumes that there is no | |
| 56 conditional inclusion of Google Mock or Google Test headers. Please | |
| 57 report any problems to googlemock@googlegroups.com. You can read | |
| 58 http://code.google.com/p/googlemock/wiki/CookBook for more | |
| 59 information. | |
