# Runs TestValidatePod in pkg/api/validation with the verbose flag set
make test WHAT=./pkg/api/validation KUBE_GOFLAGS="-v" KUBE_TEST_ARGS='-run ^TestValidatePod$'
# Runs tests that match the regex ValidatePod|ValidateConfigMap in pkg/api/validation
make test WHAT=./pkg/api/validation KUBE_GOFLAGS="-v" KUBE_TEST_ARGS="-run ValidatePod\|ValidateConfigMap$"
或者直接用go test
go test -v k8s.io/kubernetes/pkg/api/validation -run ^TestValidatePod$
并行测试
并行测试是root out flakes的一种有效方法:
# Have 2 workers run all tests 5 times each (10 total iterations).maketestPARALLEL=2ITERATION=5
生成测试报告
make test KUBE_COVER=y
Benchmark测试
go test ./pkg/apiserver -benchmem -run=XXX -bench=BenchmarkWatch
集成测试
Kubernetes集成测试需要安装etcd(只要按照即可,不需要启动),比如
hack/install-etcd.sh # Installs in ./third_party/etcd
echo export PATH="\$PATH:$(pwd)/third_party/etcd" >> ~/.profile # Add to PATH
# Run integration test TestPodUpdateActiveDeadlineSeconds with the verbose flag set.maketest-integrationKUBE_GOFLAGS="-v"KUBE_TEST_ARGS="-run ^TestPodUpdateActiveDeadlineSeconds$"
End to end (e2e)测试
End to end (e2e) 测试模拟用户行为操作Kubernetes,用来保证Kubernetes服务或集群的行为完全符合设计预期。
make WHAT='test/e2e/e2e.test'
make ginkgo
export KUBERNETES_PROVIDER=local
启动cluster,测试,最后停止cluster

有用的-ctl
# -ctl can be used to quickly call kubectl against your e2e cluster. Useful for# cleaning up after a failed test or viewing logs. Use -v to avoid suppressing# kubectl output.gorunhack/e2e.go---v-ctl='get events'gorunhack/e2e.go---v-ctl='delete pod foobar'
