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


- 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

- 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.
