Test Execution Script
For the sample code in this repository, runTests.sh allows you to easily build the test executable, run the tests, and generate coverage output.
code/runTests.sh
#!/bin/bash
# check coverage flag
if [ "$1" == "--coverage" ]; then
echo "Coverage mode enabled."
COVERAGE_FLAGS="-DCMAKE_CXX_FLAGS=--coverage -DCMAKE_C_FLAGS=--coverage"
else
echo "Running tests without coverage."
COVERAGE_FLAGS=""
fi
# build
cd test/test
cmake $COVERAGE_FLAGS CMakeLists.txt
make
# run test suites
./runTests
# if coverage enabled, generate coverage report
if [ "$1" == "--coverage" ]; then
echo "Generating coverage report..."
# create coverage directory
mkdir -p ../../coverage
# colect coverage info
lcov --capture --directory . --output-file coverage.info
# remove test code, google test code, and other library code coverage from report
lcov --remove coverage.info '/usr/*' '*/gtest/*' '*/gmock/*' '*/test/*' --output-file coverage_filtered.info
# generate coverage report
genhtml coverage_filtered.info --output-directory ../../coverage
echo "Coverage report generated in root/coverage directory."
fi
Running the Tests
If you only want to run the tests, execute the script as shown below:
cd code
bash runTests.sh
The test results will be displayed in the terminal.
Generating Coverage Reports
If you want to generate a coverage report in addition to running the tests, execute the script with the coverage option as shown below:
cd code
bash runTests.sh --coverage
The coverage report will be output as an HTML file under code/coverage by the coverage tool lcov1. You can check the coverage for each file.
Clicking on the links for each file will show how many times each line has been executed.
