Usage: test-flake [<options ...>]
|
|
|
|
Description:
|
|
|
|
test-flake surfaces flakiness in tests by constraining CPU resources.
|
|
|
|
Single or package-wide tests are run for multiple iterations with a configurable
|
|
amount of CPU resources.
|
|
|
|
0.15 CPUs and 30 iterations are configured as reasonable defaults.
|
|
|
|
See Docker docs for more info on tuning 'cpus' param:
|
|
https://docs.docker.com/config/containers/resource_constraints/#cpu
|
|
|
|
Options:
|
|
|
|
--pkg="" Target package
|
|
--test="" Target test (requires pkg flag)
|
|
--cpus=0.15 Amount of CPU resources for container
|
|
--n=30 Number of times to run tests
|
|
|
|
Examples:
|
|
|
|
./test-flake.sh --pkg connect/proxy
|
|
./test-flake.sh --pkg connect/proxy --cpus 0.20
|
|
./test-flake.sh --pkg connect/proxy --test Listener
|
|
./test-flake.sh --pkg connect/proxy --test TestUpstreamListener
|
|
./test-flake.sh --pkg connect/proxy --test TestUpstreamListener -n 100
