Documentation

Overview

Package framework contains provider-independent helper code for building and running E2E tests with Ginkgo. The actual Ginkgo test suites gets assembled by combining this framework, the optional provider support code and specific tests via a separate .go file like Kubernetes' test/e2e.go.

Functions

func AddOrUpdateLabelOnNode added in v1.4.0 

func AddOrUpdateLabelOnNode(c clientset.Interface, nodeName string, labelKey, labelValue string)

AddOrUpdateLabelOnNode adds the given label key and value to the given node or updates value.

func AllNodesReady 

func AllNodesReady(c clientset.Interface, timeout time.Duration) error

AllNodesReady checks whether all registered nodes are ready. TODO: we should change the AllNodesReady call in AfterEach to WaitForAllNodesHealthy, and figure out how to do it in a configurable way, as we can't expect all setups to run default test add-ons.

func AssertCleanup 

func AssertCleanup(ns string, selectors ...string)

AssertCleanup asserts that cleanup of a namespace wrt selectors occurred.

func BlockNetwork 

func BlockNetwork(from string, to string)

BlockNetwork blocks network between the given from value and the given to value. The following helper functions can block/unblock network from source host to destination host by manipulating iptable rules. This function assumes it can ssh to the source host.

Caution: Recommend to input IP instead of hostnames. Using hostnames will cause iptables to do a DNS lookup to resolve the name to an IP address, which will slow down the test and cause it to fail if DNS is absent or broken.

Suggested usage pattern: 

func foo() {
	...
	defer UnblockNetwork(from, to)
	BlockNetwork(from, to)
	...
}

}

TestContextType contains test settings and global state. Due to historic reasons, it is a mixture of items managed by the test framework itself, cloud providers and individual tests. The goal is to move anything not required by the framework into the code which uses the settings.

The recommendation for those settings is:

  • They are stored in their own context structure or local variables.
  • The standard `flag` package is used to register them. The flag name should follow the pattern <part1>.<part2>....<partn> where the prefix is unlikely to conflict with other tests or standard packages and each part is in lower camel case. For example, test/e2e/storage/csi/context.go could define storage.csi.numIterations.
  • framework/config can be used to simplify the registration of multiple options with a single function call: var storageCSI { NumIterations `default:"1" usage:"number of iterations"` } _ config.AddOptions(&storageCSI, "storage.csi")
  • The direct use Viper in tests is possible, but discouraged because it only works in test suites which use Viper (which is not required) and the supported options cannot be discovered by a test suite user.

Test suite authors can use framework/viper to make all command line parameters also configurable via a configuration file. 

var TestContext TestContextType

TestContext should be used by all tests to access common context data.
