| # acov is a tool for gathering coverage information from a device and generating |
| # a report from that information. To use: |
| # |
| # 1. sudo apt-get install lcov |
| # 2. Build application/library with coverage information. |
| # 3. Push the new binaries to the device. |
| # 4. Run tests with the additional environment variables: |
| # * GCOV_PREFIX=/data/local/tmp/gcov |
| # * GCOV_PREFIX_STRIP=`echo $(ANDROID_BUILD_TOP) | grep -o / | wc -l` |
| # 5. Run `acov`. |
| # |
| # acov will pull all coverage information from the device, push it to the right |
| # directories, run lcov, and display the coverage report (currently by opening |
| # it in your browser). |
