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.

func BlockNetwork ¶

func BlockNetwork(from string, to string)

func foo() {

	...
}

Also, it ensures that at least minPods are running and ready. It has separate behavior from other 'wait for' pods functions in that it requests the list of pods on every iteration. This is useful, for example, in cluster startup, because the number of pods increases while waiting. All pods that are in SUCCESS state are not counted.

If ignoreLabels is not empty, pods matching this selector are ignored.

func WaitForPodsSuccess ¶

the test invokes the returned cleanup function, usually in an AfterEach
the test suite terminates, potentially after skipping the test's AfterEach (https://github.com/onsi/ginkgo/issues/222)

PatchItems has the some limitations as LoadFromManifests: - only some common items are supported, unknown ones trigger an error - only the latest stable API version for each item is supported

LoadFromManifests loads .yaml or .json manifest files and returns all items that it finds in them. It supports all items for which there is a factory registered in Factories and .yaml files with multiple items separated by "---". Files are accessed via the "testfiles" package, which means they can come from a file system or be built into the binary.

LoadFromManifests has some limitations:

aliases are not supported (i.e. use serviceAccountName instead of the deprecated serviceAccount, https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.11/#podspec-v1-core) and silently ignored
the latest stable API version for each item is used, regardless of what is specified in the manifest files

}

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.
