From 9f71fcf440030a8ac3ba0d8af0eda3eb629e5269 Mon Sep 17 00:00:00 2001 From: Zach Wasserman Date: Sat, 3 Apr 2021 11:42:27 -0700 Subject: [PATCH] Speed up MySQL tests (#585) Improves MySQL test time (on my 2020 MBP) to ~18s from ~125s. - Use separate databases for each test to allow parallelization. - Run migrations only once at beginning of tests and then reload generated schema. - Add `--innodb-file-per-table=OFF` for ~20% additional speedup. --- Makefile | 6 +- docker-compose.yml | 3 +- server/datastore/datastore_test.go | 1 - server/datastore/mysql_test.go | 120 ++++++++++++++++----- server/live_query/redis_live_query_test.go | 5 - server/pubsub/query_results_test.go | 5 - server/sso/session_store_test.go | 6 +- 7 files changed, 100 insertions(+), 46 deletions(-) diff --git a/Makefile b/Makefile index a4b6b4559f..88b9abeb3f 100644 --- a/Makefile +++ b/Makefile @@ -42,10 +42,6 @@ ifdef CIRCLE_TAG DOCKER_IMAGE_TAG = ${CIRCLE_TAG} endif -ifndef MYSQL_PORT_3306_TCP_ADDR - MYSQL_PORT_3306_TCP_ADDR = 127.0.0.1 -endif - KIT_VERSION = "\ -X github.com/kolide/kit/version.appName=${APP_NAME} \ -X github.com/kolide/kit/version.version=${VERSION} \ @@ -123,7 +119,7 @@ lint-go: lint: lint-go lint-js test-go: - go test -tags full ./... + go test -tags full -parallel 8 ./... analyze-go: go test -tags full -race -cover ./... diff --git a/docker-compose.yml b/docker-compose.yml index ff38199eac..b3fe56ed2a 100644 --- a/docker-compose.yml +++ b/docker-compose.yml @@ -16,7 +16,8 @@ services: mysql_test: image: mysql:5.7 - command: mysqld --datadir=/tmpfs --slow_query_log=1 --log_output=TABLE --log-queries-not-using-indexes --event-scheduler=ON + # innodb-file-per-table=OFF gives ~20% speedup for test runs. + command: mysqld --datadir=/tmpfs --slow_query_log=1 --log_output=TABLE --log-queries-not-using-indexes --event-scheduler=ON --innodb-file-per-table=OFF tmpfs: /tmpfs environment: *mysql-default-environment ports: diff --git a/server/datastore/datastore_test.go b/server/datastore/datastore_test.go index a4f5cc9487..b30cabcb25 100644 --- a/server/datastore/datastore_test.go +++ b/server/datastore/datastore_test.go @@ -34,7 +34,6 @@ var testFunctions = [...]func(*testing.T, kolide.Datastore){ testCreateUser, testSaveUser, testUserByID, - testPasswordResetRequests, testSearchHosts, testSearchHostsLimit, testSearchLabels, diff --git a/server/datastore/mysql_test.go b/server/datastore/mysql_test.go index 14f26f9c08..c5a52472b7 100644 --- a/server/datastore/mysql_test.go +++ b/server/datastore/mysql_test.go @@ -1,7 +1,10 @@ package datastore import ( + "database/sql" + "fmt" "os" + "os/exec" "testing" "github.com/WatchBeam/clock" @@ -13,46 +16,115 @@ import ( "github.com/stretchr/testify/require" ) -func setupMySQL(t *testing.T) (ds *mysql.Datastore, teardown func()) { +const ( + schemaDbName = "schemadb" + dumpfile = "dump.sql" + testUsername = "root" + testPassword = "toor" + testAddress = "localhost:3307" +) + +func connectMySQL(t *testing.T, testName string) *mysql.Datastore { config := config.MysqlConfig{ - Username: "fleet", - Password: "insecure", - Database: "fleet", - // When using docker-compose.yml for local testing - Address: "127.0.0.1:3307", - } - - // When using Docker link on CI - if h, ok := os.LookupEnv("MYSQL_PORT_3306_TCP_ADDR");
