From 7fd7788556f191adec0aca49581ba147efb8ba26 Mon Sep 17 00:00:00 2001 From: Warren Fernandes Date: Wed, 9 Sep 2020 14:43:12 -0600 Subject: [PATCH] Refactor MachineHealthCheck tests Converts Ginkgo based test suite to a vanilla go test framework with individual sub-tests to avoid shared state between test runs. Some other refactors include moving all private test helper functions to bottom of the file and renaming current Ginkgo test suites. --- .../machinehealthcheck_controller_test.go | 1987 ++++++++++------- controllers/machinehealthcheck_targets.go | 6 +- .../machinehealthcheck_targets_test.go | 2 +- controllers/remote/suite_test.go | 4 +- controllers/suite_test.go | 109 +- test/helpers/envtest.go | 1 - 6 files changed, 1191 insertions(+), 918 deletions(-) diff --git a/controllers/machinehealthcheck_controller_test.go b/controllers/machinehealthcheck_controller_test.go index f522aef3dd1b..e0c4eb3865ae 100644 --- a/controllers/machinehealthcheck_controller_test.go +++ b/controllers/machinehealthcheck_controller_test.go @@ -21,7 +21,6 @@ import ( "testing" "time" - .
