How to compare Go benchmark in TravisCI
Although the article is for Go, but you still can use concept part for others language.
Frist we create a script called bench_compare.sh:
if [ "${TRAVIS_PULL_REQUEST_BRANCH:-$TRAVIS_BRANCH}" != "master" ]; then
REMOTE_URL="$(git config --get remote.origin.url)";
cd ${TRAVIS_BUILD_DIR}/.. && \
git clone ${REMOTE_URL} "${TRAVIS_REPO_SLUG}-bench" && \
cd "${TRAVIS_REPO_SLUG}-bench" && \
git checkout master && \
go test -bench . ./... > master_bench.out && \
git checkout ${TRAVIS_COMMIT} && \
go test -bench . ./... > current_bench.out && \
go get golang.org/x/tools/cmd/benchcmp && \
benchcmp master_bench.out current_bench.out;
fiThen I usually would execute it at after_success this section,
.travis.yml:
script:
# testing part
after_success:
# ignore
- bash ./bench_compare.shp.s. write script part is just want to tell you it's located at that indention
Now let me explain the script, basically we peek ${TRAVIS_PULL_REQUEST_BRANCH:-$TRAVIS_BRANCH} is not master first.
To make sure we are not at master branch, if we are not at master, then we start to compare the benchmark result.
Here has a point, $(git config --get remote.origin.url) is required, you can write git checkout master to know why.
Then we checkout master and ${TRAVIS_COMMIT}(I think this variable already tell you what is it), do benchmarking and store them.
Final step we download golang.org/x/tools/cmd/benchcmp for comparing, and compare two result file.
